Exploring mechanical transmission methods and their application examples
Worm gear mechanism, as one of the top ten mechanical transmission methods, is mainly used to transmit motion and power between two intersecting shafts. Its uniqueness lies in its smooth and noise free transmission characteristics.
Example of belt drive shaft breakage
For motors connected by pulleys, when some customers equip the motor output shaft with pulleys, if the pulleys are too heavy or the belt is installed too tightly, it can also cause the motor output shaft to experience continuous alternating bending stress during operation.
