The main application form of transmission machinery

Posted by uuuseff on November 18th, 2019

Transmission machinery is the use of mechanical transmission of power and movement transmission. Transmission machinery in mechanical engineering is widely used, there are many forms, can be divided into two categories: ① by friction between components to transmit power and movement of the friction transmission, including belt drive, rope drive and friction wheel drive. Friction transmission easy to achieve CVT, most can adapt to the shaft spacing larger transmission occasions, overload slippage also play a role in cushioning and protection of the transmission, but this kind of transmission generally can not be used in high-power situations, can not guarantee accurate The transmission ratio. ② rely on the initiative and follower engagement or through middleware meshing transmission power or motion of the meshing transmission, including the gear transmission, chain drive, screw drive and harmonic drive. Meshing drive can be used for high-power occasions, drive more accurate, but generally require higher manufacturing accuracy and installation accuracy. The basic product categories of transmission machinery: ① Coupling ② Continuously variable transmission: It uses transmission belts and work with variable diameter main and driven wheels to cooperate to transmit power, continuous changes in transmission ratio can be achieved, resulting in transmission and engine The best match of working condition. Common continuously variable transmission with hydraulic mechanical continuously variable transmission and metal belt CVT (CVT-CVT) ③ screw ④ slide and so on
