Assembly technology of hollow integral high-accuracy decelerating device

Abstract

The invention discloses an assembly technology of a hollow integral high-accuracy decelerating device. The assembly technology comprises the following steps that a covering plate is mounted at a gearring; a first cycloidal gear and a second cycloidal gear are mounted; an input shaft is mounted at the first cycloidal gear and the second cycloidal gear; steel balls are mounted; an output shaft is mounted in the gear ring; steel balls are mounted; and a bolt is used for penetrating a hinge pin to connect a rigid disc, the first cycloidal gear, the second cycloidal gear and the output shaft. Theinner and outer rings of a deep groove ball bearing are respectively arranged at the gear ring, the output shaft, the input shaft, the first cycloidal gear and the second cycloidal gear, the inner andouter rings are omitted, and raw materials can be saved.

Description

technical field [0001] The invention relates to an assembly process of a reducer, in particular to an assembly process of a hollow integrated high-precision reducer device capable of reducing the transmission error of the reducer, and belongs to the technical field of reducers. Background technique [0002] The planetary gear reducer with small tooth difference is a new type of reducer developed based on the principle of planetary gear transmission. The reducer assembly adopts integral bearings, pin shafts and pin sleeves, and its position tolerance increases the gap between the pin shaft and pin sleeve cycloidal wheels. [0003] Such as figure 1 As shown, it is the most commonly used planetary gear reducer with small tooth difference in the market, including ring gear 1, output shaft 2, rigid disc 3, input shaft 4, first cycloidal wheel 5, second cycloidal wheel 6, pin Set 7, pin shaft 8, needle roller 9, cover plate 10, bolt 11, first integral bearing 12, second integral...

AI Technical Summary

Problems solved by technology

[0005] 1. The outer circumference of the input shaft 4 is connected to the first cycloidal wheel 5 and the second cycloidal wheel 6 through the first integral bearing 12 and the second integral bearing 13. Multiple parts must be processed separately and then assembled multiple times , its assembly error is large

[0006] 2. The pin shaft 10 and the pin sleeve 7 are processed and assembled separately, resulting in assembly errors

[0007] 3. The outer circumference of the output shaft 2 is connected to the casing through the third integral bearing 14 and the fourth integral bearing 15, and multiple parts are processed and assembled separately, resulting in assembly errors
