Planet wheel installation device and method

Abstract

The invention discloses a planet wheel installation device. The planet wheel installation device is arranged on a planet wheel and a planet carrier, and comprises a planet wheel hoisting mechanism and a planet wheel positioning mechanism, wherein the planet wheel hoisting mechanism comprises a hoisting rod, a transverse beam and a hoisting slide block; and one end of the transverse beam is fixedly connected with the hoisting rod and the other end of the transverse beam is fixedly connected with the hoisting slide block; the planet wheel positioning mechanism comprises an upper supporting cover, a lower supporting cover, a central wheel assembly and a planet wheel assembly; the central wheel assembly and the planet wheel assembly are movably arranged between the upper supporting cover and the lower supporting cover; and the central wheel assembly and the planet wheel assembly are matched so that the planet wheel hoisting mechanism can be expanded and retracted. The planet wheel installation device is simple in structure, low in machining cost, simple and convenient in installation process, wide in applicable range and good in use effect, and has very high application and popularization values.

Description

technical field [0001] The invention relates to a planetary wheel installation device and an installation method thereof, which is especially suitable for centering and positioning the planetary pin holes of the planetary wheel and the planetary carrier during the installation process, and belongs to the field of planetary wheel installation. Background technique [0002] There are usually the following ways to install the planetary gear: [0003] 1. For planetary gears with small size and light weight, they are usually installed in the planetary carrier by manual handling. [0004] 2. For planetary gears with large volume and heavy mass, there are several installation methods as follows: [0005] A. Use lifting rings and slings to hoist the planetary gear to the planetary carrier, and then manually push the planetary wheel to the installation position in the planetary carrier. Since this method cannot fully insert the planetary gear into the planetary carrier, the planeta...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: a. Since there is no fixed connection between the hoisting device and the planetary gear, there is still a risk of the planetary wheel slipping during the hoisting process; b. The design stiffness of the bottom support of the hoisting device is limited by the planetary pin hole boss on the planetary carrier. Height limitation; c. The versatility of the positioning ring is not strong

[0010] Although the above-mentioned technical scheme can solve the hoisting problem of the planetary gear, it still has certain shortcomings

Specifically, the problem solved by the above-mentioned technical solution is very single, it can only complete the hoisting of the planetary gear, and cannot realize the alignment and positioning of the planetary gear and the planetary carrier

In addition, the device structure in the above technical solution is relatively complex, the processing cost is high, and the versatility is poor, it is difficult to guarantee the use effect when facing products of different sizes and specifications
