Problems solved by technology

like figure 1 As shown, the traditional method of measuring the center diameter of the cage pocket is: based on the outer diameter, use a vernier caliper to measure the outer width of the pocket, and qualitatively analyze and measure the change in the center diameter of the pocket by drawing the edge width (drawing the bottom tip) Quantity, the traditional measurement method measures the center diameter of the pocket hole, and the dimensional error cannot be quantitatively analyzed, which makes the inspection efficiency of the product in the first article confirmation and mass production low, and the wide edge is easy to scratch the bottom of the pocket hole

Embodiment Construction

[0036] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] Such as Figure 2-7 As shown, a method for measuring the center diameter of the cage of a thrust spherical roller bearing includes the following steps:

[0038] ① Install a measuring column 3 in the two pockets 2 of the longest chord of the measured cage 1, the measuring column 3 is composed of a cylinder at one end and a truncated cone at the other end. The longitudinal section is an isosceles trapezoid and the inclination angle of the waist of the trapezoid is the same as the inclination angle α of the pocket hole. Cooperate, the central axis of measuring column 3 coincides with the central axis of pocket hole 2;

[0039] ②Measure the distance between the circular platforms of the two measuring columns 3 with a special-purpose caliper 4. The special-purpose caliper includes a main ruler 41, a measuring cla...

Abstract

The invention discloses a measuring method of a cage pocket of a thrust self-aligning roller bearing. According to the measuring method, the central diameter of the cage pocket is measured by employing a special measuring column and a special caliper, a calculating method of a measuring value of the central diameter of the pocket is deduced and summarized, manufacturing deviations of the central diameter of the pocket can be analyzed in a quantitative manner, the conventional method of qualitative analysis and measurement of the central diameter of the pocket is changed into the method of quantitative analysis and measurement of the central diameter of the pocket, the measuring efficiency and the measuring result of the central diameter of the pocket can be greatly improved, and the scratch of the product due to detection can be avoided.

Description

technical field [0001] The invention belongs to the technical field of detection of bearing cages, and in particular relates to a method for measuring pocket holes of thrust self-aligning roller bearing cages. Background technique [0002] At present, in the field of testing solid cages for low-speed, high-load thrust spherical roller bearings, the measurement of the center diameter of the cage pocket is a very important test, and the test results are an important indicator for whether the product is qualified. Such as figure 1 As shown, the traditional method of measuring the center diameter of the cage pocket is: based on the outer diameter, use a vernier caliper to measure the outer width of the pocket, and qualitatively analyze and measure the change in the center diameter of the pocket by drawing the edge width (drawing the bottom tip) Quantity, the traditional measurement method measures the center diameter of the pocket hole, and the dimensional error cannot be quant...
