Detecting device for detecting sealing property of bearing sealing elements

Abstract

The invention discloses a detecting device for detecting the sealing property of bearing sealing elements. The detecting device comprises a detecting seat, the detecting seat is internally provided with a detecting cavity, a rotating main shaft penetrates into the detecting cavity, the rotating main shaft is rotationally installed on the detecting seat, the rotating main shaft is connected with apower mechanism for driving the rotating main shaft to rotate, a fixing sleeve is further fixed in the detecting cavity, the fixing sleeve is arranged on the rotating main shaft in a sleeving manner,and a mounting cavity is formed between the fixing sleeve and the rotating main shaft. A test assembly includes a test bearing and two test sealing elements, the two test sealing elements are arrangedon the two sides of the test bearing, an air pressure detector is arranged outside the detecting seat, an air pressure detecting probe of the air pressure detector is inserted into the test sealing elements, the detecting seat is connected with a medium supply device, and the detecting cavity is further provided with a medium outlet. The sealing performance of the bearing sealing elements under various environments can be tested, operation is simple, the detection efficiency is high, and noise is small.

Description

technical field [0001] The invention relates to the field of bearing equipment, in particular to a detection device for detecting the sealing performance of a bearing seal. Background technique [0002] Bearings can withstand loads of different sizes in high-speed motion. The bearings are composed of a complete set of precision balls, cages, and inner and outer rings. Wheel bearings are widely used in general industry, automobile industry, agriculture, chemical industry and household appliances industry. Performance testing is an important part of the bearing before it leaves the factory, and the sealing performance testing of the bearing is the most important performance in all performance testing, because the bearing is often invaded by external pollutants during operation, resulting in abrasive wear of the bearing , Fatigue spalling, so the corresponding sealing structure is installed around the bearing, which can effectively reduce the damage of the bearing and ensure th...

Performance testing is an important part of the bearing before it leaves the factory, and the sealing performance testing of the bearing is the most important performance in all performance testing, because the bearing is often invaded by external pollutants during operation, resulting in abrasive wear of the bearing , Fatigue spalling, so the corresponding sealing structure is installed around the bearing, which can effectively reduce the damage of the bearing and ensure the safe operation of the vehicle. Experimental equipment capable of simulating the environment is needed, but the prior art lacks such corresponding experimental equipment for leak detection
