The invention relates to a novel rotation type sealing ring performance test machine, which comprises a headstock and a main shaft. The excircle of the main shaft is provided with a stepped shaft. The two ends of the stepped shaft are sleeved with a bearing. The main shaft passes through sidewalls at the two sides of the headstock. The sidewalls on the two sides of the headstock are provided with bearing pedestals and the bearing is arranged on the bearing pedestals. The rear end of the main shaft is in sleeved connection with a belt pulley. The belt pulley is connected with the output end of a deceleration motor through a belt. The front end of the main shaft is connected with a flange seat, and the front end of the flange seat is connected with an experimental shaft. The front end of the experimental shaft is sleeved with a sealing ring. A cavity is filled with liquid and the main shaft is a hollow spindle. The rear end of the hollow spindle is provided with a cold air inlet port. According to the technical scheme of the invention, the novel rotation type sealing ring performance test machine is simple in structure and convenient in operation. The hollow spindle is adopted and an air-blast cooling device is arranged at the rear end of the hollow spindle. Therefore, the temperature of the bearing during the high-speed rotation of the hollow spindle can be effectively reduced.
Description
technical field [0001] The invention relates to a sealing ring performance testing machine, in particular to a novel rotary sealing ring performance testing machine. Background technique [0002] The sealing ring performance testing machine is used to measure the sealing performance of the sealing ring. The main shaft drives the test shaft to rotate at high speed, the sealing chamber is fixed, and the test shaft is given a certain amount of eccentricity. After rotating for a period of time, the oil leakage of the sealing ring is observed. Phenomenon. Generally, the test is carried out in a dust-free environment. However, the existing sealing ring performance testing machine has complex structure and inconvenient operation. During the working process, the bearings will generate high temperature when the main shaft and the rotating shaft rotate at high speed, which will affect the test effect and service life. Contents of the invention [0003] In view of the above defects...
