We present you a self-locking worm gear made of high-quality materials. The worm gear is characterized by durability and solidity. What does self-locking mean? This makes it possible to drive the gear with a worm, but at the same time do not give a chance to drive it with a worm wheel. Why? Because in such a situation there is a significant resistance resulting from the friction and cooperation of the worm and worm teeth. This, in turn, is due to their specific shape. Thus, self-locking occurs when the shear angle of the worm coil line is smaller than the friction angle. Considering that the sheer angle is most often in the range of 15 to 30 degrees.
