Mechanical transmission system

Mechanical transmission system: It is an important part of the machine tool, mainly driven by ball screws. Ball screws are integrated with the moving shaft during the transmission process, and the machine tool uses an electric motor as the transmission. The function of mechanical transmission is to transmit motion and force. Common types of mechanical transmission include gear transmission, worm gear transmission, belt transmission, chain transmission, and wheel system.

Belt Drive

According to the different cross-sectional shapes of the belt, it can be divided into flat belt, V-belt, and special belt (such as multi wedge belt, circular belt, etc.) Belt transmission has a simple structure, smooth transmission, can buffer and absorb vibrations, can transmit power between large shaft distances and multiple shafts, and is low-cost, lubrication free, and easy to maintain. But it cannot guarantee accurate transmission ratio, resulting in low transmission efficiency. Belt drive is mainly used in long-distance transmission scenarios with smooth transmission and less strict transmission ratio requirements for medium and small power. 

chain drive

Chain drive is a type of meshing transmission that uses chains as flexible pulling elements between two or more sprockets. Compared with belt transmission, the main advantages of chain transmission are: no sliding; High efficiency, η≈98%； No significant tension is required, and the load acting on the shaft is relatively small; Can be used in environments with high temperatures and humidity. The main disadvantage is that it can only be used for transmission between parallel axes; The instantaneous speed is uneven, and it is not as smooth as belt transmission during high-speed operation; Not suitable for application in transmission with large load changes and rapid reverse direction; There is noise during work, etc. Compared with gear transmission, chain transmission has the following main characteristics: lower requirements for manufacturing and installation accuracy; When the center distance is large, its transmission structure is simple; The instantaneous chain speed and instantaneous transmission ratio are not constant, resulting in poor transmission stability. Chain transmission is widely used as a fixed ratio transmission, and can also be made into a stepped chain transmission and a continuously variable chain transmission.
