The worm gear mechanism has the following characteristics:

1、High reduction ratio:
The worm gear transmission mechanism can achieve a large proportion of reduction, usually the reduction ratio can reach 10:1 to 828:1 and so on.
2、Large torque output:
The worm gear transmission mechanism can output large torque due to its large gear contact area.
3、High precision and stability:
Since the gear contact mode of worm gear transmission is sliding contact, the transmission process is relatively stable without impact and wear.
4、Self-locking feature:
The helical teeth of the worm and the helical teeth of the worm wheel make the system have a self-locking feature, which can maintain a certain position when the power supply is stopped.
