Abstract

The invention discloses a kind of processing method of rolling bearing, rolling bearing is made of inner ring, outer ring, rolling element, retainer, and processing method includes：（1）Outer ring and the processing process of inner ring, forging mechanical refining cold roll technology shaping turning processing and heat treatment grinding demagnetizing and cleaning；（2）The processing process of retainer, preliminary machining obtain crude green body heat treatment grinding；（3）Rolling element processing process：By the processing heat treatment hard grind fine grinding of raw material cold-heading molding photosphere；（4）To process outer ring, inner ring, retainer, rolling element carry out antirust treatment, then assembled.The processing method of rolling bearing provided by the invention has simplified common process technological process, improves production efficiency, reduces financial cost, while also improves bearing machining quality, improves its accuracy and service life.

Description

A kind of processing method of rolling bearing
Technical field
The present invention relates to field of machining, and in particular to a kind of processing method of rolling bearing.
Background technology
Rolling bearing is that the sliding friction between axis and axle bed by operating becomes rolling friction, so as to reduce friction loss A kind of precision mechanical organ.The basic structure of rolling bearing is inner ring, outer ring, rolling element, retainer composition.Wherein inner ring It with journal engagement, and rotates together with the axis, plays a supportive role.Outer ring is engaged with bearing block, is played a supporting role.Rolling element is borrowed Help retainer uniformly rolling element is distributed between inner ring and outer ring, shape size and quantity directly affect the axis of rolling The performance held and service life.Retainer can be uniformly distributed rolling element, prevent rolling element from coming off, and guiding rolling element has rotated profit Sliding effect.
Since rolling bearing structure is simple, is suitble to produce in enormous quantities, so many manufactories are all producing, but it is common plus Work technological process is complicated, and production cost wastes a little.
The content of the invention
It is an object of the present invention to provide a kind of processing methods of rolling bearing, have simplified common process technological process, have carried High production efficiency reduces financial cost, while also improves bearing machining quality, improves its accuracy and using the longevity Life.
Technical scheme：A kind of processing method of rolling bearing, rolling bearing is by inner ring, outer ring, rolling element, guarantor Frame composition is held, processing method includes：（1）Outer ring and the processing process of inner ring forge processing-annealing-cold roll technology shaping-vehicle Cut processing-heat treatment-grinding-demagnetizing and cleaning；（2）The processing process of retainer, preliminary machining obtain crude green body- Heat treatment-grinding；（3）Rolling element processing process：By raw material cold-heading molding-photosphere processing-heat treatment-hard grind-essence Mill；（4）To process outer ring, inner ring, retainer, rolling element carry out antirust treatment, then assembled.
The processing method of foregoing rolling bearing, it is described（1）Middle heat treatment condition is 750-850 DEG C of oil quenching and 145- 165 DEG C of lonneal.
Compared with prior art, the processing method of rolling bearing provided by the present invention specifies the making work of all parts Skill process step, while common process technological process has been simplified, it improves production efficiency, reduce financial cost, while also carry High bearing machining quality improves its accuracy and service life.
