The treatment method of the planetary gear of the planetary reducer that cannot rotate

Planetary gears generally refer to planetary gears. It is a gear system that can rotate around its own rotation axis like a fixed shaft gear, and its rotation axis can also rotate around other gear axes with the planet carrier.The planetary gear mechanism occupies a small space, the transmission ratio is stable, and the transmission is stable and efficient.It can not only play the role of high power and high speed, but also suitable for low speed mechanical devices.The main transmission mechanism of the planetary reducer includes: bearings, planetary gears, sun gears and ring gears.This article focuses on how to deal with the situation that the planetary gear of the planetary reducer cannot rotate.

Analysis of the reasons why the planetary gear of the planetary reducer cannot rotate

The maintenance personnel of the Babman planetary reducer found the following three problems during the dismantling and inspection of the planetary gear:

(1) The thrust pads on both sides are severely ablated and melted;

(2) There is a large amount of sludge at the copper sleeve, which causes the lubricating oil channel to be blocked, the copper sleeve is cracked as a whole, and the axial extension is nearly 30mm; (3) The pin shaft is partially cracked.

Based on the analysis of the above damage causes, after the copper sleeve is blocked in the lubrication hole, the copper sleeve will rise sharply, and the temperature will rise to a certain level, which will cause the copper sleeve to crack and expand, and finally contact with the thrust pads on both sides.After the thrust pad is squeezed, the temperature will rise rapidly, and finally ablate, so the pin shaft will bear a large torque and high temperature, resulting in cracks.
