Method and device for measuring and selecting gasket of taper bearing

Abstract

The invention relates to the field of mechanical assembly, disclosing to a method for measuring and selecting a gasket of a taper bearing. The method comprises the following steps of: 1, assembling all workpieces except the gasket to be measured according to the normal work state of a taper bearing drive system; 2, simulating the pressure and the speed during the normal work of the taper bearing drive system, and measuring the overall dimension under actual working conditions; and 3, comparing the dimension measured in the step 2 with the dimensions of the bearing inner rings of an upper taper bearing and a lower taper bearing and spacer bushes in static states, wherein the difference value is the thickness of the gasket to be measured. According to the method, the actual operation conditions of the workpieces can be completely simulated for measuring, the measurement accuracy is high, and the real value of the thickness of the actually required gasket can be measured. Meanwhile, the invention also provides a gasket measuring device, which can ensure that the assembled gasket conforms to the actual needs of pretightening the bearings. The detection can be completed by means of the device, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of mechanical assembly, in particular to a method and device for measuring and selecting tapered bearing gaskets. Background technique [0002] There is a huge gap between my country and foreign countries in the field of mass manufacturing of automobiles, construction machinery, and agricultural machinery. The main reason for the gap is not the appearance factors such as seats, but the internal gap between the three major power components: engine, gearbox and axle. In gearboxes, axles and other transmission systems, there are a large number of applications of tapered bearings and angular contact bearings, and the control of axial preload is the key. If the control is not good, it will cause problems such as bearing damage, oil seal leakage, and gear noise. The load-carrying capacity of the transmission system is greatly reduced and the service life is reduced, which also causes Chinese manufacturing to stay at a low-q...

AI Technical Summary

Problems solved by technology

In gearboxes, axles and other transmission systems, there are a large number of applications of tapered bearings and angular contact bearings, and the control of axial preload is the key. If the control is not good, it will cause problems such as bearing damage, oil seal leakage, and gear noise. The bearing capacity of the transmission system is greatly reduced and the service life is reduced, which also causes the Chinese manufacturing to stay at a low-quality level in the international impression

In the past few decades of rapid development, in terms of processing technology, technicians in this field have done a lot of work and have been effectively improved, but they have not really solved all the problems. Poor assembly quality has become the bottleneck of the development of the transmission system, and the axial Preload becomes core issue
