Lightweight structure method of planetary gear reduction gearbox

Abstract

The invention provides a box body lightweight structure realization method of the reduction gear box of a planetary gear. The method comprises following steps: a, building the 3D model of the box body structure of the reduction gear box; b, through dynamic analysis, obtaining the load force borne by the gear box under the maximum stress; c, through static analysis, obtaining the displacement cloud picture of the 3D model; d, obtaining the location at which rigidity needs to be reinforced; and e, carrying out rigidity reinforcement to the location at which the rigidity needs to be reinforced and reducing the thickness of the outer surface wall of the box body of the gear box. According to the method provided by the invention, the box body structure of the gear box is promoted; the rigidity distribution of the gear box is optimized; the uneven rigidity distribution condition is avoided; the integral wall thickness of the lower box body of the planetary gear is reduced without reducing the load; the rigidity demand is satisfied; the vibration condition is a little different from that before optimization; the weight of the gear box is greatly reduced; and the gear box is enabled to realize the lightweight demand effectively.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a lightweight structure method for a planetary gear reduction gear box. Background technique [0002] The gear box bears the force from the gear and the reaction force generated during gear transmission, and must have sufficient rigidity to withstand the force and moment, prevent deformation, and ensure transmission quality. The design of the gearbox case should be carried out in accordance with the layout arrangement of the power transmission, the processing and assembly conditions, and the requirements for easy inspection and maintenance. With the continuous rapid development of the gearbox industry, more and more industries and different enterprises have applied the gearbox, and more and more enterprises have developed and grown in the gearbox industry. [0003] The existing gear box structure faces two major problems: 1. The rigidity of some positions cannot meet the expected requir...

AI Technical Summary

Problems solved by technology

[0003] The existing gear box structure faces two major problems: 1. The rigidity of some positions cannot meet the expected requirements, and the box is easily damaged during the use of the box; 2. The overall weight of the box is too large, which causes resources The waste also affects the working efficiency of the hoist
