Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a wear resistance strength detection device. Background Art

[0002] The cage refers to a bearing part that partially wraps all or part of the rolling elements and moves with them. It is used to isolate the rolling elements and usually guide the rolling elements and keep them in the bearing. When the rolling bearing is working, especially when the load is complex and the rotation is high-speed, the cage is subject to great centrifugal force, impact and vibration. There is a large sliding friction between the cage and the rolling elements, and a large amount of heat is generated. The combined effect of force and heat will cause the cage to fail, and in severe cases, it will cause the cage to burn and break. Therefore, it is necessary to test the wear resistance of the bearing cage.

[0003] After searching, the publication number is (CN216449165U), which discloses a bearing retainer wear resistance strength detection device, including a base, a fixing ring is fixedly arranged at the top edge position of the base, hydraulic cylinders are fixedly arranged at the four corners inside the fixing ring, four groups of friction blocks are fixedly arranged at the output ends of the hydraulic cylinders, a motor with the output end facing upward is installed at the center position of the bottom end of the base, the output end of the motor is fixedly connected to an output shaft that passes through the base, a support ring is fixedly arranged on the outer side of the output shaft, and a retainer is arranged on the outer side of the support ring.

[0004] When implementing this technical solution, there are at least the following defects: although this utility model can perform wear resistance detection on the mechanical parts of the bearing cage, different cages need to replace different support rings for support detection, which is too cumbersome, and although the elastic connecting cloth is set to block the debris generated by the detection, it is inconvenient to collect and process the debris, which is urgently needed to be improved. Therefore, we propose a wear resistance strength detection device. Utility Model Content

[0026] A fixing bar 3 is arranged between the fixing rods 23, and a traction rope 31 is fixedly connected to the lower end of the fixing bar 3. A servo motor 4 is fixedly installed at the lower end of one side of the detection frame 1, and a transmission rod 5 is installed at the output end of the servo motor 4. A winding drum 32 is fixedly installed in the middle of the transmission rod 5, and the other end of the traction rope 31 is wound around the outer wall of the winding drum 32. The transmission rod 5 is movably connected to the upper end of the collecting bag 21, and the rubber rod 6 is arranged on the outer side of the collecting bag 21, so that it is convenient to collect and process the debris under the guide row through the setting of the collecting bag 21. A spring rod 14 is fixedly installed on the outer side of the friction block 13, and the spring rod 14 is movably connected to the support plate 12, so that it is convenient to cooperate with the friction block 13 through the spring rod 14, so as to ensure the fit between the friction block 13 and the retaining frame, and further ensure the wear-resistant detection effect. The upper ends of the rotating motor 11 are fixedly connected to the detection frame 1 through electric cylinders on both sides, so that the rotating motor 11 is driven downward by the electric cylinder, so as to facilitate the detection of the retaining frame.

[0027] Rubber rods 6 are fixedly mounted on both sides of the transmission rod 5 , and the rubber rods 6 are arranged below the arc-shaped plate 2 . The arrangement of the rubber rods 6 facilitates the arc-shaped plate 2 to be struck by the rubber rods 6 .
