Problems solved by technology

However, first of all, increasing the measurement points will inevitably lead to a decrease in measurement efficiency. In addition, there may be gaps between the bearing inner ring, rollers, and bearing outer rings, so the height of the bearing outer ring obtained by point measurement itself will have errors. thus affecting the measurement accuracy

Embodiment Construction

[0027] Next, the specific implementation manner of the present invention will be further described in detail in conjunction with the accompanying drawings.

[0028] refer to figure 1 , After the bearing is installed on the shaft 4, it is necessary to measure the height H1 of the outer ring of the bearing relative to a reference plane P to select a shim to adjust the axial clearance. In the prior art, generally, multiple groups of symmetrical points A are selected (only one point is shown in the figure), measured with a height vernier caliper, and then averaged. The more measurement points, the more accurate the measurement value, but the lower the measurement efficiency.

[0029] to combine figure 1 , figure 2 , because there is a gap S between the bearing outer ring 1, the roller 2 and the bearing inner ring 3, when measuring point A, when the measuring claw of the height vernier caliper (not shown) presses on point A, the bearing outer ring will A few flips occur so tha...

Abstract

The invention provides an aid for detecting bearing outer ring height. The aid is of an upside-down-bowl-shaped structure, the lower edge of the aid is a continuously-annular bearing outer ring compression portion, a protruding measuring portion is arranged at the center of the upper end face of the aid, the bearing outer ring compression portion surrounds a recessed portion, and the inner diameter of the recessed portion is in clearance fit with a shaft head of a shaft of a mounting bearing to axially position the aid. The invention further provides bearing outer ring height detecting equipment with the aid and a method utilizing the aid for bearing outer ring height detection. By the aid, the equipment and the method, the bearing outer ring height can be detected efficiently and accurately.

Description

technical field [0001] The invention relates to the field of measurement, in particular to an auxiliary device, equipment and method for detecting the height of a bearing outer ring. Background technique [0002] Various forms of bearings such as balls, rollers, and needles are often used in mechanical equipment, automobiles and other fields. The axial clearance of bearings directly affects the service life of bearings, the smooth operation and reliability of transmission components. In some cases, the installation accuracy of the bearings is very high. For example, when tapered roller bearings are installed back to back, the axial clearance of the bearings is required to be 0.05mm-0.07mm, and the installation accuracy has reached the level of 0.01mm. At this time It is necessary to use a height vernier caliper or a detection method with higher precision to accurately measure the height of the outer ring of the bearing before selecting a suitable gasket to ensure the axial c...
