Embodiment Construction

[0030] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0031] A measuring device for the axial clearance of a four-row tapered roller bearing, the measuring device includes an adjusting device, an inner ring clamping device, an outer ring loading device and a clearance measuring device.

[0032] The adjustment device is centered on the inner spacer ring 6 and has a symmetrical structure up and down. The upper inner ring 5 and the lower inner ring 7 form a hollow structure. The inner spacer 6 is located between the upper inner ring 5 and the lower inner ring 7. A round hole is opened in the center of the inner spacer 6. The diameter of the round hole of the inner spacer 6 is Smaller than the inner diameters of the upper inner ring 5 and the lower inner ring 7 . The first row of rollers 1 and the second row of rollers 2 are installed on the outside of the upper ...

Abstract

The invention belongs to the technical field of measurement of the axial play of bearings, and relates to a measuring method and measuring device aiming at the axial play of four-row tapered roller bearings. The measuring device is mainly composed of an adjusting device, an inner ring clamping device, an outer ring loading device and a play measuring device. By adjusting the position of a threadedguide rod relative to a guide sleeve, clamping of different inner rings is achieved; through the loading device, loading of different rows of rollers is achieved. The measurement of the axial play oforiginal four-row tapered roller bearings is equivalently converted into the measurement of the axial play of three sets of two-row tapered roller bearings ingeniously, the measuring method is simpleand easy to operate, self-locking of rollers is avoided, during measurement, turning is not needed, the method can be implemented through automated equipment, and the measuring efficiency and the measuring precision are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of bearing axial clearance measurement, and relates to a measuring method and a measuring device for the axial clearance of a four-row tapered roller bearing, which are used for measuring the axial clearance of the four-row tapered roller bearing. Background technique [0002] The structure of four-row tapered roller bearings is complex and there are many components. For a long time, the measurement of its axial clearance often adopts the traditional overall measurement method or separate measurement method, and it is measured manually with tools such as feeler gauges. [0003] However, the overall measurement method and the split measurement method have relatively large limitations. In the overall measurement method, due to the effect of gravity, there is a phenomenon that the large end of the roller does not contact the large rib of the inner ring, which leads to a large measurement result. In the split me...
