AI Technical Summary

Technical Problem

Existing methods for manufacturing angular contact ball bearings generate waste and require additional machining, leading to increased costs and logistical challenges due to the separation and further processing of bearing rings, which can result in defects and inefficiencies.

Method used

A method where both bearing rings are formed concentrically on a single forming blank, with rolling raceways on one side, and a predetermined separation point is introduced to facilitate easy separation after heat treatment, eliminating the need for additional machining and reducing logistical efforts.

Benefits of technology

This method reduces waste, minimizes additional processing steps, and decreases the risk of defects by ensuring both bearing rings are hardened together, allowing for efficient assembly and reducing the overall production time and costs.

Abstract

Method for manufacturing bearing rings of an angular contact ball bearing (1, 20, 30), in which a first bearing ring (7, 17, 27) of an angular contact ball bearing (1, 20, 30) and a second bearing ring (8, 18, 28), each with at least one rolling raceway (5, 6, 15, 19, 32, 33) for rolling elements (2) of the angular contact ball bearing (1, 20, 30), are first manufactured together in one piece and then separated, wherein a forming blank (10, 22, 29, 36) is formed which has both bearing rings (7, 8, 17, 18, 28) concentrically in one piece and on which the first bearing ring (7, 17, 27) radially connects to the second bearing ring (8, 18, 28) on its inner circumference, whereby the first bearing ring (7, 17, 27) is surrounded on its outer circumference by the second bearing ring (8, 18, 28) and is connected to it in one material on the forming blank (10, 22, 29), characterized in that both rolling raceways (5, 6, 15, 19, 32, 33) are on the same side of the forming blank (10, 22,29) are formed by embossing and the forming blank is produced from a wire.
