Embodiment Construction
[0012] Such as figure 1 , 2 As shown, the present invention is a medium and large rolling bearing radial clearance measuring instrument, including a measuring platform 2 perpendicular to the ground, and a locking device 5 is installed on the measuring platform 2 to lock or loosen the bearing to be tested 4 Inner ring, under the locking device 5 is installed a bearing adjustment positioning device 6 so as to hold the outer ring of the bearing 4 to be tested and adjust the height of the outer ring of the bearing 4 to be tested from the ground; above the locking device 5 is installed The dial indicator positioning device 1 has a dial indicator 3 installed on the dial indicator positioning device 1.
[0013] The locking device 5 includes a threaded rod, one end of the threaded rod is fixed on the measurement platform 2 and the other end of the threaded rod passes through the pressure plate and the locking nut in turn, and the threaded rod is perpendicular to the surface of the measure...

The invention relates to a measuring instrument for radial internal clearance of a medium-large rolling bearing. The measuring instrument is characterized by comprising a measuring table (2) perpendicular to the ground, wherein a locking device (5) is mounted on the measuring table (2), so that the inner ring of the bearing (4) to be measured can be locked or loosened; a bearing adjustment and location device (6) is mounted below the locking device (5), so that the outer ring of the bearing (4) to be measured can be supported, and the height of the outer ring of the bearing (4) to be measured above the ground can be adjusted; a dial gauge location device (1) is mounted above the locking device (5); and a dial gauge (3) is mounted on the dial gauge location device (1). After the measuring instrument is adopted, operators can accurately measure and control bearing radial internal clearance parameters; the inaccuracy of the traditional filler gauge measuring method is avoided; the product quality and the production efficiency are improved; the labor intensity of the operators is reduced; and the market competitiveness of a bearing product is improved.
Description
Technical field [0001] The invention relates to a radial clearance measuring instrument for medium and large rolling bearings. Background technique [0002] At present, there is still no special bearing radial clearance measuring instrument in the domestic market. The usual measurement method is still feeler gauge measurement. Because the feeler gauge measurement is controlled by humans, the operator has the measurement technique and operating experience. Large differences can cause measurement errors that cannot be controlled. Summary of the invention [0003] The purpose of the present invention is to provide a radial clearance measuring instrument for medium and large rolling bearings, which can accurately measure the radial clearance parameters of medium and large rolling bearings. [0004] A measuring instrument for radial clearance of medium and large rolling bearings. Its special feature is that it includes a measuring platform perpendicular to the ground, and a locking devi...
