In the mechanical assembly structure, pin connection (Pin Connection) is one of the most commonly used precision positioning means. It is widely used in heavy equipment, gearboxes, couplings, machine tool benchmarks and other fields because of its advantages of simple structure, convenient manufactu

Chain drive is a mechanical transmission method that uses chains to transfer power from one rotating part (the driving sprocket) to another rotating part (the driven sprocket). The driving sprocket engages with the chain, causing it to move. The chain then engages with the driven sprocket, enabling

Gear side clearance refers to the gap between the working tooth surfaces and the non-working tooth surfaces of a gear pair, typically measured along the meshing line. For helical gears, it is measured along the meshing line perpendicular to the tooth surface. What factors usually influence gear side

As one of the core components of the transmission system, the fatigue performance of gear directly affects the service life of the whole equipment under the action of long-term alternating load. How to accurately calculate the fatigue life of gear and how to improve its fatigue resistance through ma
