Measuring device of bearing outer ring

Abstract

The invention discloses a measuring device of a bearing outer ring. The measuring device comprises a chassis. A first installation groove and a second installation groove are arranged in the chassis in an interlaced manner. A first support column is arranged in one end of the first installation groove. Second support columns cooperating with the first support column are respectively arranged in two ends of the second installation groove. Support rotation discs cooperating with tooth moving grooves in the bearing outer ring are rotatably arranged in the first support column and the second support column. A dial indicator is arranged on the chassis via a support. The watch hand of the dial indicator is abutted against the upper end face of the bearing outer ring. The measuring device is advantageous in that the tooth moving grooves arranged in the bearing outer ring rotate on the support rotation discs, so distance from the tooth moving grooves to the bearing outer ring can be quickly measured, thereby acquiring range of parallelism. The measuring method is simple to operate and high in measuring precision; measurement can be easily performed; yield can be effectively ensured; and post-installation quality and product producing quality are improved.

Description

technical field [0001] The invention relates to a bearing measuring device, in particular to a bearing outer ring measuring device. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads in the process of mechanical transmission. Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. The structure of the bearing mainly includes: the outer ring of the bearing and the inner ring of the bearing, the rolling elements and the cage that are rolled between the outer ring of the bearing and the inner ring of the bearing, and the gear groove is also arranged on the outer ring of the bearing. , it is necessary to comprehensively measure the parallelism between the gear groove and the end face of the bearing outer ring. If the deviation exceeds the rate...

Problems solved by technology

The structure of the bearing mainly includes: the outer ring of the bearing and the inner ring of the bearing, the rolling elements and the cage that are rolled between the outer ring of the bearing and the inner ring of the bearing, and the gear groove is also arranged on the outer ring of the bearing. , it is necessary to comprehensively measure the parallelism between the gear groove and the end face of the bearing outer ring. If the deviation exceeds the rated value, it can only be treated as a scrap product. It was originally measured by a vernier caliper and compared visually. This measurement method is not accurate. The outer ring of the bearing needs to be measured many times, the operation is cumbersome, the error is large, and it is difficult to guarantee the yield rate, which will affect the overall installation quality and shipment quality in the later stage
