A measuring device for the inner hole of a bearing sleeve

Abstract

The invention provides a bearing sleeve inner hole measuring device and belongs to the technical field of bearings. The bearing sleeve inner hole measuring device solves the technical problem that in the prior art, produced bearings cannot be detected, so that bearing quality and the pass rate cannot be guaranteed, and production cost is increased. The technical scheme is that the bearing sleeve inner hole measuring device comprises a base. A fixed base, a movable base and a control mechanism are sequentially installed on the base, a clamping mechanism is arranged on one side of the fixed base next to the movable base, a detection rod is axially installed on the clamping mechanism, the movable base is provided with a detection support and a support, the detection support is provided with a detection hole, the detection hole and the detection rod are coaxial, the pore diameter of the detection hole is larger than the external diameter of the detection rod, the control mechanism is connected with the movable base and controls the movable base to move on the base, and the detection rod can move along with the movable base to penetrate through the detection hole. A bearing sleeve is detected, product quality and the pass rate are improved, the service life of the bearing sleeve is prolonged, and production cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of bearings, and relates to a measuring device, in particular to a measuring device for measuring the inner hole of a bearing sleeve. Background technique [0002] Bearing is an indispensable mechanical part in the transmission process of the machine. It plays the role of fixing and reducing the friction coefficient of the load. It is installed on the machine and moves relative to each other with other parts on the shaft to reduce the power transmission. Process the coefficient of friction and keep the shaft center position fixed. 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. [0003] Bearings are high-precision products, and their precision, performance, life and reliability play a decisive role in the precision, performance, life and reliability of the main engine, so the precision of...

AI Technical Summary

Problems solved by technology

[0004] However, since the bearing has a certain length, the bearing sleeve will produce a certain error during the manufacturing process, which makes the overall bearing sleeve bend slightly in the axial direction, especially the axial linearity of the inner wall of the bearing sleeve is poor, and different parts, Different degrees of protrusion or depression, if these errors are not corrected in time, it will cause the following two problems. First, the product quality of the bearing sleeve will be reduced, and the service life will be shorter, which will greatly reduce the qualified rate of the product and increase its quality. The production cost affects the overall reputation and production efficiency of the enterprise; second, during the use of the bearing sleeve, the resistance between the bearing sleeve and the shaft increases, the friction coefficient also increases immediately, and the axial movement performance is poor, so that the bearing cannot perform its due role
