At this time, the bearing to be tested is placed on the spindle 3, and the L-shaped hook 30 is located in the auxiliary groove 31. Then, the first cylinder 44 and the second cylinder 38... 8. Reset: Under the action of the first elastic connecting piece 27 and the second elastic connecting piece 35, the L-shaped hook 30 contacts the inner ring of the bearing, and the bottom end of the auxiliary pressing transmission rod 37 contacts the top of the outer ring of the bearing under test. At this time, the top end of the auxiliary pressing transmission rod 37 contacts the measuring pen 29, and the measuring pen 29 measures the first data. Then, the lifting cylinder 42 drives the lifting frame 43 to lift, so that the lifting frame 43 abuts against the bottom surface of the outer ring of the bearing under test. At this time, the measuring pen 29 measures the second data. The difference between the first data and the second data is the radial clearance of the bearing under test.

[0034] The bearing radial clearance measuring device of this technical solution has an ingenious structural design and strong practicality. It can adjust the distance between the bottom end of the auxiliary clamping transmission rod 37 and the L-shaped hook body 30 to adapt to the radial clearance measurement of bearings of different sizes. Using this bearing radial clearance measuring device, the radial clearance of larger bearings can be measured, which effectively improves the efficiency of bearing radial clearance measurement and also effectively ensures the production efficiency of bearings.
