It’s very important for an automobile manufacturer to keep an eye on the transmission system of the vehicle in order to provide effective power transfer to the wheels. The transmission gears and shafts help in supplying power to the wheels though smooth and efficient working.
The transmission gears and shafts are used to produce variation in gear ratio through the application of different sized gears having the same module. The reduction of gear ratio is important as it helps in reducing the high rotational speed produced by the engine. Along with this the transmission shafts also plays a vital role in transferring power at some distance.
Generally, the gears used for such work contains round gears or ring gears. The round gears are either spur or helical and exist with a module ranging from 1-7. The finishing is supplied to the gears through shaping, shaving, and grinding. The ring gears exist with a module 1.5-7 and are used as transmission gears. The transmission shaft is made up of the case hardening steel or through hardening steel along with a length varying from 50-600 mm depending upon the requirement.
Thus, transmission gears and shafts are the key parts for the working of an automotive.
