Machining process of special-shaped bearing

Abstract

The invention relates to the technical field of special-shaped bearing machining processes, and discloses a machining process of a special-shaped bearing. The machining process comprises the followingsteps that a bar is blanked, and blanking operation is carried out on the bar by adopting a sawing machine; forging is performed, and a hot forging mode is adopted; spheroidizing annealing is carriedout; datum plane machining, bearing inner ring machining and outer ring rough machining are carried out, a CNC milling machine machining reference plane is adopted, and an inner ring and an outer ring of the bearing are subjected to rough machining; a datum hole is machined, and linear cutting is adopted to machine a datum hole; the reference surface is finely ground, a grinding machine is adopted, the datum plane is subjected to finish machining, and meanwhile burrs at the hole opening of the datum hole are ground; finish machining is carried out on the inner ring of the bearing, the reference plane and the datum hole are taken as the positioning reference, ultra-fine grinding are carried out on the channel, the inner diameter and the slope surface of the bearing inner ring by a lathe; and the outer ring of the bearing is machined, the outer ring of the bearing is subjected to ultra-fine grinding machining by taking the inner diameter and the reference surface of the bearing as a machining reference, and the lathe is adopted for carrying out ultra-fine grinding on the outer ring of the bearing. The machining process of the special-shaped bearing has the advantages of being accurate in positioning accuracy and high in product machining precision.

Description

technical field [0001] The invention relates to the technical field of special-shaped bearing processing technology, in particular to a special-shaped bearing processing technology. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. At present, the structure of the outer ring of the common double row angular contact ball bearing is: the two ends are plane and parallel to each other, and the outer diameter, inner diameter, groove and slope surface are all coaxial annular bodies. The outer diameter is positioned and accurate, and the surface such as plane, outer diameter, inner diameter, groove and slope surface is turned, ground and super-finishing, so as to achieve high-precision processing quality and meet design requirements. And for such as figure 1 and figure 2 For the spe...
