Embodiment Construction
[0011] Specific embodiments of the present invention are described in conjunction with the accompanying drawings.
[0012] The method described in the present invention is used for small and medium-sized external teeth quenching slewing bearing outer rings (such as figure 2 ) processing technology, the processing process is: car end face 1 → car tooth top outer diameter 2 → car small outer diameter 3 → car outer inner diameter 4 → car channel 5 → car sealing groove 6 → channel 5 surface quenching → initial Grinding plane 1 → grinding small outer diameter 3 → initial grinding tooth top outer diameter 2 → milling tooth 7 → tooth 7 quenching → final grinding plane 1 → final grinding tooth top outer diameter 2 → grinding outer inner diameter 4 → grinding groove 5; combined image 3 , when quenching the surface of the channel, set two slewing bearings side by side, and heat treat the channel surfaces of the two slewing bearings at the same time, which can increase the relative hei...

The invention discloses a method for processing an outer ring of a small and medium-sized external gear quenching rotary disc bearings. The processing method includes the following steps: processing an end surface of a vehicle; processing a top outer diameter of a vehicle gear; processing a small outer diameter of the vehicle; processing an inner diameter of the vehicle; processing a channel of the vehicle; processing a sealing groove of the vehicle; performing quenching of the channel surface; preliminary-grinding the panel; grinding the small outer diameter; grinding the top outer diameter of the gear; processing gear milling; performing gear quenching; final-grinding the plane; final-grinding the top outer diameter of the gear; grinding the outer inner diameter; and grinding the channel. During the quenching of the channel surface, the two rotary disc bearings are arranged side by side, and the channel surfaces of the two rotary disc bearings are subjected to heat treatment at the same time; during gear milling, the gear milling of two rotary disc bearings needs to be processed at the same time; and during gear quenching, the gears of the two rotary disc bearings are preformed heat treatment at the same time. Through the change of the process flow, the problems of size shrinkage and quenching crack avoidance during quenching of a product are solved, the stability of qualityis guaranteed, and the processing efficiency of the product is improved.
Description
technical field [0001] The invention relates to a processing technology for an outer ring of a slewing bearing, and mainly relates to a processing method for an outer ring of a slewing bearing with small and medium-sized external teeth quenching. Background technique [0002] The slewing bearing is a bearing with a special structure that can bear a large axial load, radial load and overturning moment at the same time, and integrates multiple functions such as support, rotation, transmission, and fixation; in general, the turntable The bearing itself has mounting holes, lubricating oil and sealing devices, and some have internal or external teeth, which can meet the different needs of various hosts working under various working conditions; on the other hand, the slewing bearing itself has Due to its compact structure, convenient guidance and rotation, easy installation and easy maintenance, large slewing bearings are often widely used in lifting and transportation machinery, ...
