4.2.1.2 Measurement method
The main items to be measured for the wave-type retaining frame are: the deviation of the center circle diameter of the retaining hole; the variation of the retaining hole depth; the deviation of the rivet center and the center circle diameter of the adjacent retaining hole; the radial movement of the steel ball in the retaining hole and the diameter of the sieve needle. 4.2.1.2.1 Measurement of the center circle diameter deviation of the retaining hole ≥Dα) Use a deep groove ball racket filter type retaining frame to measure the center circle diameter of the retaining hole and the depth of the retaining hole for inspection (see Figure 2). The measuring heads are two spherical bodies with the same center size as the ball of the measuring cage. When measuring, the center of the cage of the same bearing model is fixed directly on the indicator table: then the cage is placed on the upper working table of the measuring instrument, and the measuring ball is selected into the cage. After the center and the ball are well matched, the value of the concave hole can be read from the indicator table. b) Use a micrometer to directly measure the center size A (see Figure 3), and calculate AF with the inverse formula: the measurement of the bore should be less than: and Nz?
