Method for measuring axial clearance of double-row conical bearing

Abstract

The invention relates to a method for measuring the axial clearance of a double-row conical bearing, which comprises the steps that an inner ring of the bearing is fixed by means of a bearing fixing device in such as manner that the two ends of the bearing are clamped in the axial direction, an outer ring of the bearing is suspended so as to enable the outer ring of the double-row roller bearing to perform axial displacement relative to the inner ring, the bearing is vertically placed, the head of a dial indicator hits a horizontal plane at the axial end of the outer ring of the bearing, the dial indicator and the bearing are relatively fixed in position, the outer ring of the bearing is toggled to enable the outer ring to perform axial drop displacement relative to the inner ring of the bearing, and the reading of the dial indicator is obtained; the bearing fixing device is flipped to enable the bearing and the dial indicator to flip in the axial direction by 180 degrees synchronously, the outer ring of the bearing is toggled to enable the outer ring to perform axial drop displacement relative to the inner ring of the bearing, and the reading of the dial indicator is obtained; and the difference of the two readings of the dial indicator is the average axial clearance of the bearing. The method realizes detection for the axial clearance by using a flipping operation, and has the advantages of simple operation and high work efficiency.

Description

technical field [0001] The invention relates to a bearing detection technology, specifically a method for measuring the axial clearance of a double-row tapered bearing. Background technique [0002] Bearing clearance is also called bearing clearance. The so-called bearing clearance refers to the amount of movement when the bearing is not installed on the shaft or bearing box, the inner ring or the outer ring is fixed, and then the unfixed side of the bearing clearance is moved radially or axially . According to the direction of movement, it can be divided into radial clearance and axial clearance. [0003] At present, there are two methods for axial clearance measurement: matching method during assembly and direct measurement method (loaded, unloaded). In the matching method during assembly, it is necessary to measure the size of each component, and then directly add and subtract; on-load measurement is a commonly used measurement method, and a certain load needs to be lo...
