Milled oblate ball cage and manufacturing method thereof

Abstract

The invention relates to a flat-square milled ball cage and a production method thereof and belongs to the technical field of ball cages. The flat-square milled ball cage comprises a ball cage seat, an input shaft integrated with the ball cage seat is arranged at the bottom of the ball cage seat, a dust cover buckled with the ball cage seat is arranged on the end face of the ball cage seat, a plurality ball cage assemblies arranged on the same axis and evenly staggered is arranged in the ball cage seat, and each ball cage assembly is provided with an output shaft which is sleeved with the ballcage assembly and extends out of the dust cover. The flat-square milled ball cage has the advantages of compact structure, even stress, inexistence of included angles and long service circle, and stability, handling and heat dissipation performance of vehicles during operation are improved; with the production method of the flat-square milled ball cage, the purposes of no concave and convex surfaces in the plane, reducing clamping of swinging angles, high rigidity precision, tight connection between the ball cage and a drive shaft, simple and practical processing technology and shortened processing cycle are realized.

Description

technical field [0001] The invention relates to the technical field of ball cages, in particular to a milled flat square ball cage and a manufacturing method thereof. Background technique [0002] It turns out that the constant velocity universal joints used in car production and car maintenance in my country mainly rely on imports, which cost a lot of foreign exchange every year. In order to develop our country's automobile industry, after more than ten years of research and development, the rough precision forging technology and production technology of the main parts of automobile constant velocity universal joints have been researched and developed. Now there are many large domestic manufacturers with this production technology, such as Wafangdian Hongda (ZWZ), Shanghai Natiefu (SDS), Hangzhou Wanxiang, Taizhou Jutai (BIK), Taizhou Hongli (LEE), Wenzhou Guansheng (GSP), Ningbo Wanhang and other domestic manufacturers have provided matching ball cages to domestic and for...

AI Technical Summary

Problems solved by technology

[0004] The invention mainly solves the deficiencies in the prior art of poor controllability, unstable swing angle of the ball cage, stuck phenomenon and short service life, and provides a milled flat square ball cage and a manufacturing method thereof. The ball cage has the characteristics of compact structure, uniform force, no included angle and long service life, which improves the stability, handling and heat dissipation performance of the vehicle during operation. Its manufacturing method solves the problem of uneven surface and swing angle Problems of stuck phenomenon, low rigidity precision, loose fit between ball cage and drive shaft, complex processing and long processing cycle
