Gear type

There are many different types of gears for different ranges of use, and all are characterized by the shaft to which they are connected or the position of the shaft (which can be parallel, intersecting, or non-standard) and their tooth profile. This is a list of the most common types and their common uses.

Spur Gears: Spur gears are cylindrical parallel shafts and spur gears, and because of their simplicity, a wide range of applications, and cost-effectiveness, it is one of the most commonly used gear types. Spur gears bear and transmit radial loads and are commonly used in low-speed applications because they tend to generate noise at higher speeds

Helical/dry fixed-gears: Helical gears are also cylindrical but have helical teeth that form a spiral shape, so they can transmit torque and thrust, although the latter is not always useful in their applications and must be accommodated. The benefits of the spiral shape of the teeth are low noise and vibration levels at operation, even at high speeds, and the ability to deliver greater loads than spur gears.

Double helical/Miter gears: A miter gear is basically two helical gears glued together side by side, with teeth in opposite directions. The reason behind this arrangement is to eliminate the thrust generated in the monohelical gears by making the loads cancel each other out. The main disadvantage is that they are difficult to manufacture with the required precision and therefore very expensive to buy.

Bevel/helical gears: Bevel gears are intersecting shaft/shaft types, so they are joined at a vertical tilt. They are conical in shape, and their teeth can be straight or spiral for quieter operation. Although 90-degree angles between interconnected shafts are not mandatory, they are usually found in this arrangement, and they have exactly the same number of teeth, so the rotational speed is the same between the two. Such bevel gears, called helical gears, are used when no change in speed is required. The number of teeth on any other Angle and difference is referred to as a Bevel Gear device.

Hypoid gears: Hypoid gears are very similar to spiral bevel gears, the main difference is that their rotation axes do not coincide. As a result, great care must be taken to fabricate the Angle of the teeth placed on the hyperbolic conical part. They are typically used in applications that require deceleration/increase in speed, so they often appear in vehicle drivelines because the pinion does not have to sit above the hypoid gear but lies on its side, allowing for a more compact implementation.

Worm Gear: Worm gear is a gear device, made up of cylindrical gears similar to helical gears. However, it also includes shaft gears which are characterized by threads arranged in parallel planes but rotating at an axial direction of 90 degrees relative to the first element. Due to the close connection of the two components, the worm gear drive operates quietly and without vibration. The most common type of worm gear application has decisive deceleration, locking, and precision characteristics. Typical examples of these types of gears are the tuning keys in stringed instruments.

Rack and pinion: Similar to the worm arrangement, the rack and pinion have a Spur Gear with a straight rack and pinion, one of which is firmly fixed in position while the other moves left and right. A typical application of rack and pinion is a steering wheel, where the spur gear is locked in position and the rack moves left and right, followed by a pull bar and steering arm that move to turn the wheel. Because the speed of the rack and pinion is very low, the teeth do not need to be tilted or helical and do not produce any sound or vibration.

Sprockets: Sprockets are a type of gear with sharp teeth because they are not meant to be attached to other gears, but to belts or chains. A typical example is a bicycle Sprocket, whose teeth enter the gap in the metal chain to move the rear wheel forward. In industry, sprockets are usually found in conveyor systems, although other types of gears are often preferred, which are safer and less prone to wear.

Inner gear: An inner gear is a cylinder with teeth within its radius. The advantage of having such gears is that they save space, and they do not rotate in the opposite direction, so they are used in applications where those characteristics are required. Most typically, they are found in planetary gear systems

Epicyclic/planetary gears: A typical arrangement of epicyclic gears (or planetary gears) consists of a central spur gear and an external spur gear that moves circumferentially around it. The point of having this arrangement is to achieve an effective conversion from reciprocating motion to rotation. A typical example of such a system is the early steam locomotive, which shows that different types of gears have historically played an important role.
