Does Self-Locking Worm Gears Really Exist

In theory, the helical gear speeders "locking" cannot be pushed back. But they do not rely solely on this feature that relates to security. Hangzhou Fanglun Drive Equipment Co., Ltd.

Here's a little quiz to test your knowledge on how worm gear endless work:
• When worm gear is self-locking or irreversible, it means that the gear worm can not drive the worm. (True or false?)

• A self-locking gear cannot be driven by the load in the opposite direction to its intended direction of rotation. Hangzhou Fanglun Drive Equipment Co., Ltd. produce servo gearbox and servo gear reducer (True or false?)
• Usually impractical to design gear worm irreversible safely. (True or false?)
The correct answer to all these statements is true, under certain conditions. Hangzhou Fanglun Drive Equipment Co., Ltd. The first statement is the article "interlocking gears: what they are, what they do," TPD 5/89. The second and third states are manual machines, 24th edition. Hangzhou Fanglun Drive Equipment Co., Ltd. produce servo gearbox and servo gear reducer
So how to reconcile these seemingly contradictory statements: the load cannot backdrive in the opposite direction, however, is not practical to design irreversible gear? Hangzhou Fanglun Drive Equipment Co., Ltd. The explanation lies in understanding the difference between the theory of gear design and the practical aspects of engineering applications.
