Embodiment 1

[0066] Such as Figure 1-Figure 4 As shown, a worm wheel type slewing bearing of this embodiment includes an outer ring 1, a middle ring 5 and an inner ring 8, and the rolling between the outer ring 1 and the middle ring 5 and between the inner ring 8 and the middle ring 5 Steel balls and spacers are installed in the track, so as to realize the two-way rotary motion of the slewing bearing. In this embodiment, a plugging hole is processed on the side wall of the middle ring 5, a plugging 6 is assembled in the plugging hole, and a certain number of steel balls and spacers are installed from the plugging hole, so as to align between the middle ring 5 and the outer ring 1 and between the middle ring 5 and the outer ring 1. 5 is connected with the inner ring 8, and the plug 6 and the middle ring 5 are fixed by the conical pin 7, that is, a plug is installed between the outer ring 1 and the middle ring 5 and between the inner ring 8 and the middle ring 5 6 and a tapered pin 7. In ...

Embodiment 2

[0069] Such as figure 1 As shown, a worm wheel type slewing bearing of this embodiment includes an outer ring 1, a middle ring 5 and an inner ring 8, and the rolling between the outer ring 1 and the middle ring 5 and between the inner ring 8 and the middle ring 5 Steel balls and isolation blocks are installed in the channel. Such as image 3 As shown, in this embodiment, the plugging hole is processed on the side wall of the middle ring 5, the plugging hole is assembled with a plug 6, and a certain number of steel balls and spacers are installed from the plugging hole, so as to align the gap between the middle ring 5 and the outer ring 1. And the middle ring 5 is connected with the inner ring 8, and the plug 6 and the middle ring 5 are fixed by the conical pin 7. The above-mentioned steel ball raceways are all processed into eccentric double-arc raceways, and after assembly between the outer ring 1 and the middle ring 5, and between the middle ring 5 and the inner ring 8, th...

Embodiment 3

[0077] The structure of the worm wheel type slewing bearing of this embodiment is the same as that of Embodiment 2, and the process flow chart of the processing method of the slewing bearing is shown in Figure 5 , including the following steps:

[0078] A. The processing procedure of outer ring 1 is: rough turning—semi-finishing turning—heat treatment (raceway quenching)—finishing turning—gear hobbing (worm gear hobbing)—marking—drilling—turning and grinding, and the specific details of each process The processing process is as follows:

[0079] 1. Rough car

[0080] 1. Take the ring-shaped blank as the processing raw material, select a relatively flat plane as the rough reference, clamp the inner hole of the outer ring 1, and process the other plane to the height required by the process; then use the processed surface as the Precise benchmark, after turning over and clamping, process the unprocessed plane to the height required by the process. The plane machining allowanc...

Abstract

The invention discloses a machining method of a worm gear type pivoting support and belongs to the technical field of pivoting support machining. The machining method of an outer ring of the worm gear type pivoting support comprises the steps of rough turning, half finish turning, heat treatment, finish turning, hobbing, scribing, drilling and lathe grinding. The machining method of a middle ring of the worm gear type pivoting support comprises the steps of rough turning, boring and drilling, half finish turning, heat treatment, finish turning, scribing, drilling and lathe grinding. The machining method of an inner ring of the worm gear type pivoting support comprises the steps of rough turning, half finish turning, finish turning I, gear shaping, heat treatment, finish turning II, scribing, drilling and lathe grinding. The pivoting support machined through the machining method can meet the requirements of entertainment machinery, light industry machinery, filling machinery and the like for bidirectional rotational motion and bear large turning torque, the abrasion resistance of gear teeth is remarkably improved, installation between a sealing ring and the pivoting support is firmer, the sealing ring and the pivoting support are not prone to falling off, and the service life of the worm gear type pivoting support is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of slewing bearing processing, and more specifically relates to a processing method of a worm wheel type slewing bearing. Background technique [0002] The slewing bearing is widely used in the actual industry, and is called "the joint of the machine". The important transmission parts necessary for machinery have the characteristics of compact structure, smooth movement, high precision and strong bearing capacity. In addition to various construction machinery, port equipment, metallurgical equipment, oil drilling platforms, and wind power generation, the application range of slewing rings has gradually expanded to the filling machinery industry, such as entertainment machinery, beverage filling machinery, wine filling machinery, etc. . [0003] At present, the traditional slewing ring equipment usually adopts a single raceway slewing ring, and the driving is transmitted through the meshing of the inner and...
