Problems solved by technology

[0003] At present, the installation part of the planetary wheel usually adopts a separate shell and cover, and the bearings set on the planetary wheel turret are respectively arranged in the shell and the cover, and finally the shell and the cover are screwed together. The overall strength of this structure is poor, and the axial clearance of the bearing has a great influence on the accuracy of the reducer. The processing method of the inner ring gear is limited by the structural design. The gear shaping method is used, and the processing efficiency is very low.

Abstract

The invention relates to a structure for eliminating the axial clearance of bearings of a planet rotating stand. The structure comprises a planet wheel mounting frame and a shell, an inner gear ring is formed on the inner wall of the shell, and a first bearing mounting step and a second bearing mounting step are processed on the shell; a planet wheel mounting cavity and a plurality of pin column mounting holes are formed in the planet wheel mounting frame, and pin columns are arranged in the pin column mounting holes in a penetrating mode; and one end of each pin column is provided with a limiting bump, and the other ends are in threaded connection with locking nuts. The integral strength is large, meanwhile,the inner gear ring can be machined through gear broaching, efficiency is improved by 16 times, axial tension is provided for the first bearing and the second bearing through the pin columns, the clearance influence of the bearings is reduced, and precision is improved; and in addition, the multiple pin columns can guarantee the coaxial assembly precision among the first bearing, the second bearing and the planet mounting frame, and then the overall coaxiality is improved.

Description

technical field [0001] The invention relates to the technical field of planetary reducers, and more specifically, to a structure for eliminating the axial clearance of planetary turret bearings, a planetary reducer and a method. Background technique [0002] The planetary reducer is used to adjust the output speed and output torque of driving equipment such as motors, and it is usually composed of core components such as a sun gear, multiple planetary gears, and an inner ring gear; [0003] At present, the installation part of the planetary wheel usually adopts a separate shell and cover, and the bearings set on the planetary wheel turret are respectively arranged in the shell and the cover, and finally the shell and the cover are screwed together. The overall strength of this structure is poor, and the axial clearance of the bearing has a great influence on the accuracy of the reducer. The processing method of the inner ring gear is limited by the structural design. The gea...
