Technical Field

[0001] This invention relates to the field of bearing wear resistance testing technology, specifically to a wear resistance testing device for drive wheel hub bearings. Background Technology

[0002] Wheel hub bearings are one of the key components of automobiles. Their main functions are to bear weight and provide precise guidance for the rotation of the wheel hub. This requires them to withstand not only axial loads but also radial loads. As the automotive industry continues to place increasing emphasis on the durability and safety of components, wear resistance testing of drive wheel hub bearings is necessary.

The electronic scale 2 is fixedly installed on one side of the top of the testing platform 1, the filtering mechanism 3 is fixedly installed inside the testing platform 1, the grinding mechanism 4 is fixedly installed on the side of the top of the testing platform 1 away from the electronic scale 2, and the rinsing mechanism 5 is fixedly installed behind the top of the testing platform 1. The filtration mechanism 3 includes a groove 301, a through hole 302, a filter frame 303, a water inlet pipe 304, and a water tank 305. The top of the testing platform 1 has a groove 301, and the inside of the groove 301 has a through hole 302. The front end of the testing platform 1 is movably provided with a filter frame 303, and the bottom end of the filter frame 303 is movably provided with a water inlet pipe 304. The rear end of the testing platform 1 is fixedly provided with a water tank 305. The water tank 305 is located at the rear end of the water inlet pipe 304 and is fixedly connected to it, which facilitates the filtration of water source after rinsing and polishing the drive wheel hub bearing body 403, filters impurities in the water source, and allows the water source to be reused.

[0016] The grinding mechanism 4 includes a motor 401, a turntable 402, a drive hub bearing body 403, a bolt 404, a mounting groove 405, a rotating block 406, a lead screw 407, a positioning nut 408, a connecting block 409, and a grinding block 410. The motor 401 is fixedly mounted at the top of the interior of the inspection table 1. The output shaft of the motor 401 extends through the inspection table 1 into the interior of the groove 301. The turntable 402 is fixedly mounted at the output shaft of the motor 401. The drive hub bearing body 403 is movably mounted at the top of the turntable 402. A bolt 404 is threaded onto the upper end of the drive hub bearing body 403, extending into the groove 406. Inside the disc 402, the top of the testing platform 1 has an installation groove 405 on the side away from the electronic scale 2. A rotating block 406 is movably arranged on one side of the testing platform 1. The rotating block 406 extends through the testing platform 1 and is fixedly installed inside the installation groove 405. A lead screw 407 is threaded on the outer end of the lead screw 407. A positioning nut 408 is threaded on the top of the positioning nut 408. A connecting block 409 is fixedly installed on the top of the connecting block 409 near the drive wheel hub bearing body 403. The grinding block 410 abuts against the drive wheel hub bearing body 403, which facilitates grinding and testing of the drive wheel hub bearing body 403.

[0017] The rinsing mechanism 5 includes a water pump 501, a connecting pipe 502, a mounting plate 503, and a gooseneck tube 504. The water pump 501 is fixedly installed at the bottom of the water tank 305, and the connecting pipe 502 is fixedly installed at the top of the water pump 501. The mounting plate 503 is fixedly installed at the rear of the top of the testing platform 1. The connecting pipe 502 passes through the top of the mounting plate 503 and the gooseneck tube 504 is fixedly installed there. The polished drive wheel hub bearing body 403 will produce some debris, which facilitates rinsing of the polished drive wheel hub bearing body 403 and facilitates subsequent weighing.

[0018] Working principle: First, when conducting wear resistance testing on the drive wheel hub bearing, the operator first places the drive wheel hub bearing body 403 on the electronic scale 2 to weigh and record the weight. Then, the drive wheel hub bearing body 403 is fixed to the turntable 402 using bolts 404. Next, rotating the rotating block 406 drives the lead screw 407 to rotate. The lead screw 407 drives the positioning nut 408, connecting block 409, and grinding block 410 to move until the grinding block 410 abuts against the drive wheel hub bearing body 403. The motor 401 drives the drive wheel hub bearing body 403 to rotate through the turntable 402. The drive wheel hub bearing body 403 rubs against the grinding block 410, generating some debris during the friction process. After a period of friction, the water pump 501 connects to the gooseneck pipe 504 via the connecting pipe 502. Water is drawn out of water tank 305. Workers can adjust the water flow position through gooseneck tube 504 to rinse drive wheel hub bearing body 403. Groove 301 can limit the water source to prevent water from flowing everywhere. Water flows back into water tank 305 through through hole 302, filter frame 303 and water pipe 304. Filter frame 303 can filter debris in the water to keep the water source in water tank 305 clear, so that the water source after rinsing can be used continuously. After long-term use, filter frame 303 can be disassembled to clean the debris inside. Then, drive wheel hub bearing body 403 is disassembled and the surface water is wiped dry. It is then weighed again on electronic scale 2. The weight difference before and after is compared to analyze the wear resistance of drive wheel hub bearing body 403.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
