The worm gear reducer is a common mechanical transmission device that achieves speed reduction through the meshing of a worm gear and a worm.
Worm gear reducers usually consist of main components such as worm gears, worms, drive shafts and bearings. The worm gear and worm are the most important parts of the reducer. Their appearance is similar to gears, but the worm gear has more teeth than the worm, and the helical angle of the tooth groove and the helical angle of the worm are reciprocal of each other.
When the reducer is working, the worm is the driving part and the worm gear is the driven part. The rotation of the worm is transmitted to the worm gear through the transmission shaft. Since the worm gear has more teeth than the worm and the helix angle, the rotation speed of the worm gear will decrease and the torque will increase. This deceleration method is achieved through friction transmission, because the contact surface between the worm gear and the worm forms a spiral friction transmission surface.
During the transmission process, the friction between the worm gear and the worm generates torque, causing the worm gear to start rotating. Since the worm gear has more teeth than the worm, each rotating worm gear tooth slot meshes with the worm gear tooth slot, thereby driving the worm to rotate. This process continues until the worm gear and worm are fully meshed, at which point the transmission process ends.
Due to the friction transmission between the worm gear and the worm, the output torque of the reducer can be transmitted to other mechanical devices, such as cranes, conveyors, etc. This reduction method has the advantages of large reduction ratio, high torque output, low noise, high efficiency, etc., so it is widely used in many mechanical transmission systems.
In short, the working principle of the worm gear reducer is to achieve deceleration through the meshing of the worm gear and the worm. This reduction method has many advantages, such as large reduction ratio, high torque output, low noise, high efficiency, etc., so it is widely used in many mechanical transmission systems.
