Mechanical transmission is one of the most important technologies in the machinery manufacturing industry, because as long as there is movement, there must be transmission. No matter what form of energy, if you want to change it into a specific movement and achieve a specific function, you must achieve it through the transmission device.
Nowadays, the research and development work in the field of mechanical transmission is mainly to optimize its existing functions. the research work is to optimize existing products on the basis of in-depth understanding of existing functions. the development work focuses on two aspects: first, reduce the cost of mechanical transmission mechanism, improve the bearing capacity, life and transmission efficiency, and reduce noise, weight, failure rate and operation cost; On the other hand, other means are used to complete the required functions. for example, electronic device numerical control system can be used to supplement or replace mechanical devices to realize the functions of mechanical elements in the past. however, from the current situation, it is possible to replace mechanical transmission with electronic components only in individual cases. In most cases, mechanical components, especially gears, are also used as components of conventional transmission. Therefore, many improvements are still aimed at mechanical transmission.
