Transmissions are richly classified. Different transmissions have different functions and different advantages and disadvantages, but in the transmission mode of the transmission, the worm gear transmission has its unique advantages.
CVT is a kind of transmission machinery with compact structure, large transmission ratio and self-locking function under certain conditions. It is one of the most commonly used transmissions. Among them, the hollow shaft worm gear transmission not only has the above characteristics Moreover, it is easy to install and has a reasonable structure, which is becoming more and more widely used.
Hollow shaft worm gear transmission is a multi-stage transmission with a helical gear transmission at the input end of the continuously variable transmission. It can obtain very low output speed. It is a combination of helical gear stage and worm gear stage. Single-stage continuously variable transmission has higher efficiency. And the vibration is small, the noise is low, and the energy consumption is low.
It cannot be ignored that the self-locking function of the continuously variable transmission transmission mode is very useful in mechanical applications, such as winches, conveying equipment, etc. But at the same time, it is because of the frictional transmission method of the continuously variable transmission that the transmission efficiency of the continuously variable transmission is much lower than that of the gear transmission.
Note: Not all continuously variable transmissions have a good self-locking function. The self-locking function of the worm gear can only be achieved by achieving a certain speed ratio.
