Production process for conical roller bearing

Abstract

The invention discloses a production process for a conical roller bearing. The production process includes the following steps of the production technological process of an outer ring, the production technological process of an inner ring and the step that after the inner ring and the outer ring are sent to an assembly workshop, the sizes of an inner ring roller path and an outer ring roller path are grouped, assembling, final inspecting, typewriting, rust protecting and packaging are conducted, and then the conical roller bearing is put in storage. The production technological process of the outer ring includes the steps of forging, lathing, thermal treatment, double end face grinding, outer diameter part coarse grinding, outer diameter part fine grinding, outer roller path coarse grinding, outer roller path fine grinding, outer roller path super-finishing, outer diameter coping and demagnetization cleaning and the step of sending the outer ring to an assembly workshop. The production technological process of the inner ring includes the steps of forging, lathing, thermal treatment, double end face grinding, inner diameter coarse grinding, inner roller path coarse grinding, large flange coarse grinding, inner roller path fine grinding, large flange fine grinding, inner diameter fine grinding, large flange super-finishing, inner roller path super-finishing and demagnetization cleaning and the step of sending the inner ring to the assembly workshop. The production process has the advantages that the complex machining procedures of an ordinary process are simplified, bearing machining quality is improved, production efficiency is greatly improved, and production cost is saved.

Description

technical field [0001] The invention relates to a production process of a bearing, in particular to a production process of a tapered roller bearing. Background technique [0002] The existing production process of general rolling bearings is as follows. Outer ring processing flow: Billet storage—pickling—blanking—capillary cooling—spheroidization—pickling—phosphating—saponification—cold drawing—annealing—general inspection of steel pipes—blanking Material—soft grinding end face—chamfering—heat treatment—grinding end face—grinding outer diameter—rolling outer diameter—grinding groove—superfinishing grinding groove. Inner ring processing flow: Billet storage—pickling—blanking—hot piercing—cold capillary inspection—pickling—phosphating—saponification—cold drawing—annealing—general inspection of steel pipes— Blanking—soft grinding end face—soft grinding outer diameter—chamfering—grooving—heat treatment—grinding end face—grinding outer diameter—rolling outer diameter—grinding ...
