Description

A single-stage hypocycloid reducer for industrial robots

Technical Field

The utility model relates to the technical field of cycloid speed reduction equipment, in particular to a single-stage hypocycloid speed reducer for an industrial robot.

Background Art

The cycloid reducer is a novel transmission device that applies the planetary transmission principle and adopts cycloid pin-tooth meshing. Its unique stable structure can replace ordinary cylindrical gear reducers and worm gear reducers in many cases, and is widely used in the manufacturing field of industrial robots.

The existing patent document with technical disclosure number CN219317571U provides a single-stage inner cycloid reducer for an industrial robot. The utility model starts a three-phase motor and the reducer body performs deceleration. During the deceleration process, the internal structure rubs and needs lubrication with lubricating oil to increase the meshing linkage between the structures. After a long period of use, the three-phase motor stops moving and the control valve is automatically opened. The lubricating oil in the oil filling tank flows into the interior of the reducer body through the oil filling pipe to lubricate the internal structure, thereby enabling the internal structure of the cycloid reducer to be automatically oiled.

However, the existing single-stage inner cycloid reducer of industrial robots is not convenient for buffering the external impact force and vibration generated during use. During the use of the cycloid reducer, when it is hit by external force, it is easy to cause certain damage to its structure. In addition, during the long-term use of the cycloid reducer, the vibration generated by the operation of its structure will cause varying degrees of wear to the internal components, which will directly affect the service life of the cycloid reducer.
