A circular key is a cylindrical connecting element that is usually installed in a shaft hole and fits with the circumference of the shaft. The circular key mainly transmits force and prevents relative axial movement through axial load.Working principle: The circular key mainly transmits force and pr

gear trainGear systems are divided into two types: fixed axle gear systems and epicyclic gear systems.The ratio of the angular velocity (or speed) of the input shaft to the output shaft in a gear train is called the transmission ratio of the gear train. Equal to the ratio of the product of all drive

RV usually uses cycloidal pinwheels, while harmonics used to use involute tooth profiles. Now, some manufacturers have used double arc tooth profiles, which are much more advanced than involute. These two reducers are worth promoting specifically

What is external force? What types of external forces are metals subjected to during deformation? The metal placed on the hammer anvil was hit by the chain head, causing a change in its original shape. We call the hammering force an external force. There are three types of external forces that metal
