Under what conditions does a turbo worm reducer lock itself?


蜗轮蜗杆减速机

Does the worm gear reducer have self-locking? Many users may not be familiar with this issue. 0.6 时,蜗杆导程角小于 3 ° 29 11 ″即自锁,反之不自锁;蜗轮付摩擦系数为 0.7 时,蜗杆导程角小于 4 ° 03 57 ″即自锁,反之不自锁;蜗轮付摩擦系数为 0.8 时,蜗杆导程角小于 4 ° 38 39 ″即自锁,反之不自锁。 When the worm gear friction coefficient is 0.6 , the worm lead angle is less than 3 ° 29 11 ″, which is self-locking, otherwise it does not self-lock; when the worm gear friction coefficient is 0.7 , the worm lead angle is less than 4 ° 03 57 ″, which is self-locking. If the friction coefficient of the worm gear is 0.8 , the lead angle of the worm is less than 4 ° 38 39 ″, that is, it is self-locking, otherwise it is not self-locking.

, 即蜗杆可以轻易转动蜗轮,但蜗轮无法转动蜗杆。 Worm gear worm reducer In the transmission mode of the reducer, worm gear transmission has the characteristics of other gear transmission , that is , the worm can easily turn the worm gear, but the worm can not turn the worm. This is because the structure and transmission of the worm gear are caused by friction. The self-locking function of the worm gear transmission method is very useful in mechanical applications, such as winches, conveying equipment, etc.

Worm gear reducer

Worm gear reducer with self-locking, convenient installation, reasonable structure, more and more widely used. Hollow shaft worm gear reducer is equipped with a helical gear reducer at the input end of the worm gear reducer. The multi-stage reducer can obtain a very low output speed. It is a combination of helical gear stage and worm gear stage. Worm gear reducer has higher efficiency. And the vibration is small, the noise is low, and the energy consumption is low.
