Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a reducer with a compact structure. Background Art

[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or actuator. It is a transmission component widely used in modern machinery. The purpose of the reducer is to reduce the speed and increase the torque to meet various work requirements.

[0003] At present, for example, a worm gear reducer is composed of a worm and a worm, and has a compact structure. Under the same output torque, it is small in size, light in weight, and easy to install, which makes it more convenient to use in a small space. Most of the existing reducers are installed on the connecting plate by screws. Since the reducer will generate vibration during operation, the existing reducer is usually buffered and shock-absorbing by dampers and buffer springs. This buffering and shock-absorbing method can effectively reduce vibration, but when the reducer faces extremely high loads or speeds, its vibration reduction effect may still not be able to fully meet the operating requirements of the equipment, resulting in these vibration reduction elements may not be able to fully absorb and disperse these forces, thereby reducing the vibration reduction effect.

[0004] Therefore, it is necessary to provide a new compact reducer to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a compact reducer.
