Application area of worm and worm self locking function

In the transmission mode of worm gear reducer, worm gear transmission has the characteristics that other gear transmission does not have, that is, the worm can easily rotate the worm gear, but the worm gear can not rotate the worm. This is because the structure and transmission of the worm and worm wheel are caused by friction.



The self-locking function of worm and worm gearing is very useful in mechanical applications, such as winch, conveying equipment and so on. However, it is also because of the worm gear and worm friction transmission mode, also caused the worm gear and worm transmission efficiency is much lower than the gear transmission.



Note: However, it should be noted that not all worm gears have good self-locking function, the self-locking function of worm gears to achieve a certain speed ratio can be achieved. This is related to the lead angle, that is, the self locking function of worm gear with small speed ratio is not so ideal.
