Problems solved by technology

[0002] In the prior art, the planetary carrier assembly applied to the eccentric oscillating gear has two input planetary carriers and output planetary carriers, which need to be used in conjunction with the two planetary carriers. The position of the pin hole, the concentricity of the bearing hole, the bearing hole There are very high requirements for the parallelism of the bearing hole, the accuracy of the bearing hole, and the end face accuracy of the planet carrier. If the input planet carrier and the output planet carrier are processed separately, it is difficult to meet the actual installation requirements. Still can not meet the ideal requirements

Embodiment 1

[0034] An eccentric oscillating gear planet carrier assembly, the eccentric oscillating gear includes a gear transmission device, and the gear transmission device includes: a crankshaft, an eccentric rotating gear, an autorotation gear and a planet carrier. The crankshaft has an eccentric body and an input gear. The eccentric rotation gear cooperates with the eccentric body and rotates eccentrically with the rotation of the crankshaft. The rotation gear meshes with the eccentric gear and has a different number of teeth from that of the eccentric rotation gear. In addition, the autorotation gear autorotates with respect to the eccentric rotation gear. The planet carrier supports the crankshaft. In this gear unit, a carrier coaxially supported by an internal gear rotates in accordance with the swinging rotation of the external gear. Bearings are supported on the planet carrier, and the crankshaft supports the external gear. An eccentric body is fixed to the crankshaft, and t...

Embodiment 2

[0095] Others are the same as in Example 1, the difference is that all processes after S3012 are processed on the same machining center without multi-step repositioning and clamping. At this time, S3024 does not need fine grinding planes for fine grinding oil seal and bearing positions, so The clamping and positioning procedures of S3021, S3023, and S3025 are cancelled.

[0096] Through the above steps, the processing technology of the planet carrier assembly is completed.

Abstract

A processing technology for an eccentric oscillating gear planet carrier assembly. The processing technology includes: the first step: rough machining the input planet carrier and the output planet carrier; the second step: taking the oil seal position plane of the output planet carrier as the reference plane, and The planet carrier and the output planet carrier are clamped and fixed; the third step: processing the taper pin hole; the fourth step: processing the second center hole of the input planet carrier, the first center hole of the output planet carrier and the second bearing hole of the input planet carrier 1. The first bearing hole of the output planetary carrier; the fifth step: turn around and input the second plane of the planetary carrier as a reference, and center the outer circle; the sixth step: finish machining the center step hole, threaded hole and first plane of the output planetary carrier ; The seventh step: process the first bearing hole and the second bearing hole and the oil seal position of the planet carrier group. Through the invention, the position degree of the pin hole, the concentricity of the bearing position, the parallelism of the bearing position, the precision of the bearing position and the end surface precision of the planet carrier are improved, and the assembly precision is guaranteed.

Description

technical field [0001] The invention belongs to the field of gear reducers, in particular to the field of eccentric swing gears. Background technique [0002] In the prior art, the planetary carrier assembly applied to the eccentric oscillating gear has two input planetary carriers and output planetary carriers, which need to be used in conjunction with the two planetary carriers. The position of the pin hole, the concentricity of the bearing hole, the bearing hole There are very high requirements for the parallelism of the bearing hole, the accuracy of the bearing hole, and the end face accuracy of the planet carrier. If the input planet carrier and the output planet carrier are processed separately, it is difficult to meet the actual installation requirements. Still can not meet the ideal requirements. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The purpose of the present invention is to provide a processing technolog...
