Planetary reducer for DELTA robot

Abstract

The invention provides a planetary reducer for a DELTA robot. The planetary reducer fixes a crossed roller bearing on a front shell through an output shaft and a first-stage planetary retainer; a second set screw connects the output shaft and the first-stage planetary retainer integrally to fix the crossed roller bearing in the axial direction; as the crossed roller bearing is small in size and large in axial (front and rear directions) bearing force, only one crossed roller bearing is adopted to enable the planetary reducer to obtain larger axial bearing force and smaller axial length; and the first-stage planetary retainer adopts a four-planet structure to improve the transmission precision and the transmission torque of the reducer so as to obtain a larger reduction ratio. Compared withthe existing planetary reducer, the planetary reducer provided by the invention is larger in bearing force and higher in precision, solves the problems that the existing planetary reducer is small inaxial bearing force, large in size, insufficient in precision, smaller in torque and short in service life and has better application in the industry of the DELTA robots.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a planetary reducer for a DELTA robot. Background technique [0002] The DELTA robot is a very commonly used robot in the general direction of Industry 4.0. Among them, the planetary reducer of the DELTA robot plays a vital role in its joints. The joints of the DELTA robot have extremely high requirements on the reducer. Due to its fast movement speed, High precision requirements, large loads and 24-hour non-stop operation, the existing planetary reducers for DELTA robots generally reflect weak axial bearing capacity, insufficient precision, large volume, low transmission torque, and insufficient life. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a planetary reducer for DELTA robot, which has large axial bearing capacity, small volume, large transmission torque, high transmission precision and hig...

[0002] The DELTA robot is a very commonly used robot in the general direction of Industry 4.0. Among them, the planetary reducer of the DELTA robot plays a vital role in its joints. The joints of the DELTA robot have extremely high requirements on the reducer. Due to its fast movement speed, High precision requirements, heavy load and 24-hour non-stop operation, the existing planetary reducers for DELTA robots generally reflect weak axial bearing capacity, insufficient precision, large volume, low transmission torque, and insufficient service life.
