[0002] The inner and outer rings of the tapered roller bearings both have tapered raceways. The tapered roller bearings are tested for stiffness by applying radial pressure.

Beneficial Effects

[0015] 1. In the present invention, the tapered roller bearing is tested multiple times by replacing the pressure push plates at different positions, so that the test results can be calculated easily. When the tapered roller bearing is tested for stiffness, the pressure push plates are driven by the adjusting carrier plate to cover the different positions along the guide groove, so that one of the adjusting carrier plates drives the pressure push plates to be at a lower position, so that the pressure rod applies radial pressure to the tapered roller bearing through the pressure push plates, and the adjusting carrier plates are rotated in turn so that the pressure push plates at different positions apply pressure on the bearing body. The same bearing can be tested multiple times to obtain multiple test results, which is convenient for calculating the test results. Even if one pressure push plate is deformed, it will not affect the test stiffness result. If the test is performed multiple times, the test result will be more accurate, which prevents the problem of error in the test result caused by the deformed pressure push plate.

[0016] 2. In the present invention, a protective plate is used to protect the bearings during the inspection process to prevent excessive pressure from causing the tapered roller bearing to rupture and splash. When the tapered roller bearing is inspected, the protective plate is located on the rear side of the bearing body, and the movable protective piece is moved to both sides on the outside of the protective plate, so that the two movable protective pieces and the protective plate form a circle to inspect the bearing body, so that the protective plate and the movable protective piece block the bearing that is ruptured due to the application of greater pressure, preventing the splashing bearing debris from splashing to other places or causing harm to the staff. At the same time, the broken debris of the bearing falls into the debris collection box through the guide groove, which is convenient to clean up. BRIEF DESCRIPTION OF THE DRAWINGS
