Ensuring the precision of the turning of bearing outer rings

Abstract

The article shows the influence of the technological system of an automated lathe, in particular cam chucks, on the accuracy of machining bearing rings for production conditions. The value of the ring out-of-roundness during the machining of a single-row tapered roller bearing 32017X on the outer diameter was investigated. For the experiment, samples of rings were selected that were machined under the same conditions, directly in production, without interference in the technological process. The use of replaceable floating cams in the chuck design is proposed to increase the accuracy and productivity of processing. The implementation of product quality accuracy control in production is presented. The influence of clamping force on the accuracy of turning rings is studied. It is shown that the quality of products is formed under the influence of the use of modern computer technologies at all stages of manufacturing and control of parts, which ensures research in a wide range of changes in technological parameters and comparison of individual studies with real machining conditions on the machine, with the results of a sufficient level of reliability.
