Description

High stability worm gear speed reducer Technical Field The utility model relates to the technical field of speed reducers, in particular to a high-stability worm gear speed reducer. Background The worm gear speed reducer is a mechanical transmission device using worm gears and worms, and is mainly used for reducing the rotating speed and increasing the output torque. Such speed reducers are very common in industrial applications, particularly where it is desired to reduce the speed of a high speed motor or engine to a speed suitable for the operational requirements. When the worm gear reducer is used, worm gears are required to be matched with each other, vibration is very easy to be caused by the matched driving mode, so that the use stability of the worm gear reducer is very easy to be affected, and when the worm gear reducer is used by utilizing a driving worm, the driving mode can affect the use stability of the whole reducer if the worm is displaced because the worm is required to be driven to rotate. Disclosure of utility model The utility model aims to provide a high-stability worm gear reducer so as to solve the problems in the background technology.
