Worm gears teeth resembles ACME screw thread which mates with a helical gear, except that it is made to envelope the worm as seen along the worm's axis. Operation of worm gears is analogous to a screw. The relative motion between these gears is sliding rather than rolling. The uniform distribution of tooth pressures on these gears enables use of metals with inherently low coefficients of friction such as bronze wheel gears with hardened steel worm gears. These gears rely on full fluid film lubrication and require heavy oil compounded to enhance lubricity and film strength to prevent metal contact.   Worm gear are the perfect choice when the need is for producing large motor speed Gear reductions in a single step. A single reduction range of 5:1 - 100:1 is considered quite a normal thing for Worm Gears. It can climb up to 127:1 or even more, under special circumstances. Worm Wheel Gears are quite in operation. Using a single-lead worm along with a 100 tooth wheel, can do wonders in a single simple step.

A timing belt pulley is part of the timing belt system for an automobile. A timing belt is one way to control the opening and closing of engine valves by connecting the crankshaft to the camshaft of the vehicle. Generally, the timing belt does this by having teeth that lock into the teeth of the two gears for the crankshaft and camshaft. A timing belt is one of several belts used in conventional cars and other vehicles. A serpentine belt is a belt that drives various other engine accessories off of the crankshaft. The serpentine belt can run an alternator, power steering pump, and air conditioning compressor. In some vehicles, these jobs are split between multiple belts,   where a vehicle usually has only one timing belt pulley.     Each belt in a vehicle may have additional pulleys to route it around the engine compartment. An idler pulley is a pulley that provides movement for the belt but does not run an accessory or engine component. A timing belt idler pulley may help provide additional track routing for the belt. The idler timing belt pulley may also be called a tensioner pulley if it helps to provide tension on the belt. A tensioner pulley is one that a vehicle owner or mechanic can adjust to change the amount of tension on the belt when needed.   A timing belt is a very crucial part of engine operation. Damage or malfunctioning of the timing belt will be a serious impediment to driving the vehicle. Those who experience problems with the timing belt of a vehicle should consult a professional mechanic who can calibrate and fix the timing belt properly for regular operation of the vehicle. Though most drivers prefer to let experienced mechanics work on any idler or tensioner timing belt pulleys when belts are having problems, others can learn how to do basic work on their vehicles including how to change tension on a belt by moving the pulley. Most tensioner pulley setups will include several bolts that hold the pulley in place. The person working on the vehicle can loosen the bolts, then adjust tension by either moving the pulley along a threaded bolt, or prying it toward or away from the engine block.   Individual vehicle owners often look at how to replace a serpentine belt or a timing belt pulley for their specific car, truck or other vehicle. Each model of car or vehicle has its own specific setup for serpentine and timing belts and the pulleys involved. Lots of vehicles have routing diagrams for belts, either on decals under the hood or in the owner’s manual. There are several advantages for selection of TIMER BELT PULLEY DRIVES : Timer belt drives are positive grip devices. There is no chordal rise or fall of pitch line, no slippage and no belt creeps. This belt require no lubrication because there is no metal to metal contact and the noise level is low in normal speed range. Cost is always and important advantage and the initial cost is usually the only expense involved. Thus, Timer belt drives are an economical means of power transmission. Timer belts have a speed range from inches per hour to approximately 16.000 fpm. Small pitch belt can transmit positive motion while operating at high speed. Speed in excess of 8000 fpm are generally impractical for large pitch belts. Power capacity of Timer belt drive ranges from subfractional to approximately 800 hp. The drive must be belted to transmit the power required by the highest load encountered. Special functions, Many Timer belts drives are used for functional rather than power transmission application. Because they travel with predictable positive, nonslip, precision, designers have created a variety of devices. As example, anguler drive, triangular drive, squre drive, deflection drives, multi shaft drive, reversing drive, conveyor belt drive etc. Also tubing cut-off system, fabricating cartons, elevator conveyor for ball bearing, drive track for snow mobile etc.

The spur gear is is simplest type of gear manufactured and is generally used for transmission of rotary motion between parallel shafts.  The spur gear is the first choice option for gears except when high speeds, loads, and ratios direct towards other options.  Other gear types may also be preferred to provide more silent low-vibration operation.  A single spur gear is generally selected to have a ratio range of between 1:1 and 1:6 with a pitch line velocity up to 25 m/s.        The spur gear has an operating efficiency of 98-99%.  The pinion is made from a harder material than the wheel.  A gear pair should be selected to have the highest number of teeth consistent with a suitable safety margin in strength and wear.The minimum number of teeth on a gear with a normal pressure angle of 20 desgrees is 18.     Spur gears are the most common type used. Tooth contact is primarily rolling, with sliding occurring during engagement and disengagement. Some noise is normal, but it may become objectionable at high speeds.  Spur gears are the most commonly used gears in the market. Spur Gears are found generally in the form of a cylinder or disk. These gears are applied for varying the force and speed of a rotating axle. These gears have a straight teeth. They are usually mounted on parallel shafts. These days mostly the tooth form is based on the involute curve. For creating large gear reductions, many spur gears are used together.   Internal Spur GearsThis is actually a type of Spur Gear. Internal Spur Gears are not much different from a regular spur gear. These gear by appearance shows pitch surface that is cylindrical. Here the tooth is parallel to the axis. In case of Internal Spur Gears, the gears are positioned to make internal contact. It is also referred to popularly as Ring gears. The output rotation produced by the Ring gears is direction wise same as that of input rotation. External Spur Gears External Spur Gears are the most popular and common type of spur gear. They has their teeth cut on the outside surface of mating cylindrical wheels. While the larger wheel is referred to as the gear and the smaller wheel is known as the pinion. Single reduction stage is the most basic type of arrangement of single pair of spur gears. Here the output rotation is in opposite direction to that of the input. In other arrangements of multiple stages higher net reduction can be achieved where the driven gear is connected rigidly to a third gear. This third gear in turn drives a mating fourth gear. This serves as the ideal output for the second stage. In this way, many output speeds on different shafts are produced starting from a just single input rotation. The image given below shows the inside of External Spur Gears. Spur Gears are the most popular form and the most efficient type of gearing for the cost when transmitting power and uniform rotary motion from one parallel shaft to another. Within the limitations of center distance, spur gears provide a positive, constant speed drive, the speed of which may be increased or decreased by increasing or decreasing the number of teeth in the driving gear. Spur Gears may be operated in a “gear-train” of two or more gears but they must all be of the same diametral pitch and pressure angle. Gears with 14-1/2° pressure angle will not operate with those cut to 20° pressure angle.

Sprocket are very popular and common gear or wheel that comes with a metal teeth which meshes perfectly with a chain or track. The term pitch is used to refer to the distance between two sprockets.  Industrial sprockets today are made in a variety of sizes. Sprockets are available in metric and also in English measurements. Sprockets do not allow gears to slip away and are specifically applied in cases where chains get engaged by gears or wheels and also in cases of motors producing rotational motions. Industrial sprockets are essentially part of the chain drives. It is important in a chain drive that the sprocket should match with the type of chain used. Interestingly, though Sprockets look like gears but it differs in few ways from Gears      Industrial Sprockets usually have more engaging teeth than the gears that has one or two. In sprockets, there is no slippage of teeth. Whereas in gears, the teeth often touch and slip against each other. There is also a variation in terms of the shape of teeth.Sprockets are used in many power transmission drive systems as a continuous drive mechanism that can accomodate large center distances. Sprockets can be made from many different materials including steel, stainless steel, plastic, nylon, bronze, aluminum and many more.A sprocket's pitch is the distance between adjacent tooth centers as shown in the diagram.The  outside diameter is measured from the tip of one tooth to the same point 180 degrees on the opposite tooth. Gears and gears a comprehensive range of stock sprockets for British Standard chain up to two inch pitch.

Combination sprockets (two or more sprockets combined having different pitch sizes and numbers of teeth). Sprockets in two or more sections, i.e. split sprockets or segmental sprockets.  Sprocket and Chain Compatibility    Most drives have an uneven number of pitches in the chain and by using a driver sprocket with an odd number of teeth, uniform wear distribution over both chain and sprocket teeth is ensured. Even numbers of teeth for both the driver and the driven sprockets can be used, but wear distribution on both the sprocket teeth and chain is poor.  Gears and gears a comprehensive range of stock sprockets for British Standard chain up to two inch pitch.

The rack and pinion is used to convert between rotary and linear motion. The rack is the flat, toothed part, the pinion is the gear. Rack and pinion can convert from rotary to linear of from linear to rotary.The diameter of the gear determines the speed that the rack moves as the pinion turns.Rack and pinions are commonly used in the steering system of cars to convert the rotary motion of the steering wheel to the side to side motion in the wheels.   Rack and pinion gears give a positive motion especially compared to the friction drive of a wheel in tarmac. In the rack and pinion railway a central rack between the two rails engages with a pinion on the engine allowing the train to be pulled up very steep slopes.     A rack and pinion is a pair of gears which convert rotational motion into linear motion. The circular pinion engages teeth on a flat bar – the rack.Rotational motion applied to the pinion will cause the rack to move to the side, up to the limit of its travel. For example, in a rack railway, the rotation of a pinion mounted on a locomotive or a railcar engages a rack between the rails and pulls a train along a steep slope. The rack and pinion arrangement is commonly found in the steering mechanism of cars or other wheel, steered vehicles. This arrangement provides a lesser mechanical advantage than other mechanisms such as recirculating ball, but much less backlash and greater feedback, or steering "feel". The use of a variable rack (still using a normal pinion) was invented by Arthur E Bishop, so as to improve vehicle response and steering "feel" especially at high speeds, and that has been fitted to many new vehicles, after he created a specialised version of a net-shape warm press forging process to manufacture the racks to their final form, thus eliminating any subsequent need to machine the gear teeth.      For every pair of conjugate involute profile, there is a basic rack. This basic rack is the profile of the conjugate gear of infinite pitch radius.A generating rack is a rack outline used to indicate tooth details and dimensions for the design of a generating tool, such as a hob or a gear shaper cutter.

Helical gear is a cylindrical shaped gear with helicoid teeth. Helical gears operate with less noise and vibration than spur gears. At any time, the load on helical gears is distributed over several teeth, resulting in reduced wear. Due to their angular cut, teeth meshing results in thrust loads along the gear shaft. This action requires thrust bearings to absorb the thrust load and maintain gear alignment. They are widely used in industry. A negative is the axial thrust force the helix form causes. Helical gears are a type of industrial gears. These gears have angled teeth that creates a thrust load on the gears while they are meshing. They are circular in shape. The teeth of helical gears  are curved along a helical path. There is a refinement in design, which helical gears enjoy over Spur Gears. Actually the leading edges of the teeth in helical gears are designed in such a way as not to be parallel to the axis of rotation. Instead, these gears are set angularly. As the gear shape is curved, the unique angle makes the tooth shape to be like a segment of helix. The angled helical gear teeth is able to engage more gradually than the spur gear teeth and makes it run in more smoothly and quietly as well.HELICAL GEARS when used on parallel shafts are similar in usage to spur gears. Where velocities exceed 1000 feet per minute, helical gears provide a stronger, smoother running gear train. This type of stock gearing is furnished in 45° helix angle. Materials available are hardened steel, steel, stainless, aluminum, bronze, nylon and non-metallic (phenolic). End Thrust is developed by helical gears, but this may be overcome through the use of thrust washers or other suitable types of thrust bearings.   The teeth on helical gears are cut at an angle to the face of the gear. When two teeth on a helical gear system engage, the contact starts at one end of the tooth and gradually spreads as the gears rotate. Two mating helical gears must have equal helix angle but opposite hand. They run smoother and more quietly. They have higher load capacity, are more expensive to manufacture. Helical gears can be used to mesh two shafts that are not parallel and can also be used in a crossed gear mesh connecting two perpendicular shafts. They have longer and strong teeth. They can carry heavy load because of the greater surface contact with the teeth. The efficiency is also reduced because of longer surface contact. The gearing is quieter with less vibration.   One interesting thing about helical gears is that if the angles of the gear teeth are correct, they can be mounted on perpendicular shafts, adjusting the rotation angle by 90 degrees.

Where two axles cross at point and engage by means of a pair of conical gears, the gears themselves are referred to as bevel gears. These gears enable a change in the axes of rotation of the respective shafts, commonly 90°. A set of four bevel gears in a square make a differential gear, which can transmit power to two axles spinning at different speeds, such as those on a cornering automobile.     There are four basic types of bevel gears-   Straight bevel gears: These gears have a conical pitch surface and straight teeth tapering towards an apex Zero bevel gears: This is similar to a bevel gear except the teeth are curved. In essence, Zero Bevel Gears are Spiral Bevel Gears with a spiral angle of zero Spiral bevel gears: The teeth are curved teeth at an angle allowing too contact to be gradual and smooth Hypoid bevel gears: These gears are similar to spiral bevel except that the pitch surfaces are hyperboloids rather than cones. Pinion can be offset above or below gear center, thus allowing larger pinion diameter, and longer longer life and smoother mesh, with additional ratios e.g., 6:1, 8:1, 10:1     The design of bevel gears results in thrust forces away from the apex. With the bearing limitations the gears have to be carefully designed to ensure that they are not thrown out of alignment as they are loaded.   The tooth-bearing faces of the bevel gear are conically shaped. These bevel gears are mounted on shafts that are 90 degrees apart, but they can conveniently be designed to work at other angles as well. By using bevel gears with different numbers of teeth (the teeth can be straight, spiral or hypoid), the rotational speed can easily be changed. Bevel gears can be used to change the direction of drive in a gear system by 90 degrees. A good example is seen as the main mechanism for a hand drill. As the handle of the drill is turned in a vertical direction, the bevel gears change the rotation of the chuck to a horizontal rotation.   The bevel gears in a hand drill have the added advantage of increasing the speed of rotation of the chuck and this makes it possible to drill a range of materials.
