What Is The Small Gear Called in A Spur Gearing System?
Feb 20, 2025| The small gears in a spur gear transmission system are commonly referred to as spur gears. Spur gears are cylindrical gears with teeth parallel to the shaft, widely used and easy to manufacture.
In a spur gear transmission system, the working principle of the small gear and the large gear is as follows: the small gear is usually used as the input shaft, with fewer teeth and faster speed but smaller torque; As the output shaft, the large gear has a large number of teeth and a slow speed but high torque. By meshing the small and large gears, the speed and torque can be adjusted to meet different work requirements.
In addition, the gear types in the spur gear transmission system also include helical gears, double helical gears, internal gears, etc., each of which has different characteristics and application scenarios
