Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] Include the following steps:

[0023] Step 1. Produce the outer ring of the bearing. The outer ring of the bearing is cast and formed through the first mold. The core of the first mold is a disc-shaped core formed by splicing five core blocks and the peripheral side is an arc edge. A mold cavity is a cylindrical cavity, and the five core blocks include two first core blocks 1, two second core blocks 2 and a rectangular core block 3, and the shape of the core...

Abstract

The invention discloses a production process of a ball bearing and relates to the technical field of production of mechanical parts. The method comprises the following steps: step one, producing a bearing outer ring: the bearing outer ring is cast and molded by a first mold, a core of the first mold is spliced by a plurality of core blocks, is disc-shaped and has arc edge on the peripheral side, and a cavity of the first mold is cylindrical; step two, producing a bearing inner ring, the bearing inner ring is cast and molded by a second mold, the second mold is provided with a cylindrical moldcore, and an arc-shaped flange is arranged on the inner wall of a cavity of the second mold. The bearing inner ring and outer ring are directly cast and molded by the molds, arc surface precision of the bearing rings is improved, and assembly precision of the bearings is further improved; the service life of the bearing is prolonged by matching a reasonable heat treatment process.

Description

technical field [0001] The invention belongs to the technical field of production of mechanical parts, and in particular relates to a production process of a ball bearing. Background technique [0002] Mechanical basic parts mainly refer to: bearings, gears, molds, hydraulic parts, pneumatic components, seals, fasteners, etc., which are an indispensable and important part of the equipment manufacturing industry, directly determining the performance of major equipment and host products, Level, quality and reliability are the key to realizing the transformation of my country's equipment manufacturing industry from large to strong. At present, the existing bearings are produced by metal cutting or forging, and the production precision is not high enough, which affects the quality of the bearings. Contents of the invention [0003] The object of the present invention is to provide a production process of the ball bearing, which improves the precision of the ball bearing, impro...
