These teeth have the same profile as the spur gear. A rack consists of teeth cut in a straight row on a flat surface. It is possible to combine spur gears with a rack to convert rotational motion to linear motion. Some disadvantages include high noise and vibration in high-speed applications and the great amount of stress the teeth are subjected to in this simple design. One of its advantages is providing high transmission efficiency while not causing axial loading of the shaft. The simple design allows for a high degree of manufacturing precision. Two differently sized spur gears can be used to change torque and RPM. They work great for moderate load and moderate speed applications and are generally used in applications where noise and vibration are not a concern. Spur gears use the parallel axes configuration in mated pairs. The teeth on spur gears are parallel and straight-cut on a cylindrical gear body. Its simple and effective design creates a possibility for a wide range of applications. Let’s learn a little more about what choices one has and what each one of them offers. The factors that may be considered are as follows:īased on these factors, the selection is further narrowed down to whether the gears will be operating on parallel/non-parallel and intersecting/non-intersecting axes. It comes down to what expectations a designer has from a gear train. There are many types of gears and each one offers some trade-offs. In case of sprockets, one or more broken teeth can cause the chain to leave its position and the system will come to a halt. Gears with a broken tooth may not be as effective as a perfect system but they will work.With sprockets, the rotational direction remains the same. If the driving shaft is rotating clockwise, the driven shaft will rotate anticlockwise. Gears transfer torque in the opposite direction.While gears are capable of transmitting torque in parallel, perpendicular, and any other orientation in between, sprockets can only do so along the parallel axis.A sprocket tooth is actually designed to fit into a cavity such as the chain of a bicycle or the tracks of a military tank.
While the teeth of two gears mesh perfectly with each other, it is not so for a sprocket.Using a sprocket and a chain helps to transmit the power over a considerably longer distance, using a chain. Gears are the preferred solution for short-distance transmissions.While at the outset, they both are similar-looking components, there are some marked differences that can help us identify them with ease. Gears and sprockets both use teeth to transfer torque.
