Problems solved by technology
[0002] At present, there is still no special measuring instrument for radial clearance of bearings in the domestic market. The commonly used measurement method is still the feeler gauge measurement. Since the feeler gauge measurement is controlled by humans, the operators have limitations in the measurement methods and operating experience. Larger differences, the resulting measurement error can not be controlled

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 measuring instrument for the radial clearance of medium and large rolling bearings. Background technique [0002] At present, there is still no special measuring instrument for radial clearance of bearings in the domestic market. The commonly used measurement method is still the feeler gauge measurement. Since the feeler gauge measurement is controlled by humans, the operators have limitations in the measurement methods and operating experience. If there is a large difference, the resulting measurement error cannot be controlled. Contents of the invention [0003] The object 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, which is special in that it includes a measuri...
