Problems solved by technology

Agricultural machinery, especially those working in paddy fields, the oil seal is a very critical part. The tightness of the oil seal directly affects the service life of the machine. Agricultural machinery working in paddy fields often works in harsh working environments such as muddy water, and muddy water is easy to penetrate through the gaps. In the sealing structure, once the oil seal fails, the sealing performance will be reduced, causing wear to the shaft and bearing, reducing the service life of the machine, and affecting the normal operation of the machine
It is very difficult to test the sealing performance of oil seals used in paddy fields due to the special working environment

Abstract

The invention discloses an oil seal sealing performance testing test bench capable of intelligently simulating paddy field environment. The oil seal sealing performance testing test bench includes a box body, a testing part and a driving mechanism; the test part includes a first cavity, a first bearing, a first oil seal, a transmission shaft assembly, a stirring mechanism and a leakage alarm device; the first cavity is located in the box body; a first mounting hole is formed in the first cavity; the first bearing is located in the first cavity; the transmission shaft assembly passes through the first mounting hole so as to be rotationally connected with the first bearing; the first oil seal is located in the first mounting hole and is mounted on the transmission shaft assembly so as to enable the transmission shaft assembly to be in sealed fit with the first mounting hole; the stirring mechanism is located in the box body; the leakage alarm device is located in the first cavity; and the driving mechanism is used for driving the transmission shaft assembly to rotate. With the oil seal sealing performance testing test bench of the invention adopted, the sealing performance of the first oil seal can be tested. The oil seal sealing performance testing test bench has the advantages of simple structure and convenient use.

Description

technical field [0001] The invention relates to the technical field of oil seal sealing performance testing, in particular to an oil seal sealing performance test bench for intelligently simulating paddy field environment. Background technique [0002] With the improvement of the level of mechanization, mechanization is widely used in the field of agricultural production. Agricultural machinery, especially those working in paddy fields, the oil seal is a very critical part. The tightness of the oil seal directly affects the service life of the machine. Agricultural machinery working in paddy fields often works in harsh working environments such as muddy water, and muddy water is easy to penetrate through the gaps. In the sealing structure, once the oil seal fails, the sealing performance will be reduced, which will cause wear to the shaft and bearing, reduce the service life of the machine, and affect the normal operation of the machine. It is very difficult to test the sea...
