A detection device and detection method for lubricating oil inside a gearbox

Abstract

The invention relates to the field of gearboxes, and specifically discloses a detection device and a detection method for lubricating oil inside a gearbox, including a sampling mechanism and a testing mechanism, and the sampling mechanism and the testing mechanism are both installed on a housing outside the gearbox ; The sampling mechanism is installed on the top side of the shell, and the testing mechanism is installed on the middle side of the shell. The accumulation of impurities on the filter increases the weight of the filter, and the pressure of the filter on the bottom support rod increases. The pressure sensor on the top of the support rod measures the pressure value, and the change of the weight of the filter is obtained through the change of the pressure value. In this way, the weight of impurities filtered out by the filter screen can be known, and the content of impurities inside the lubricating oil can be judged by the weight of the filtered impurities, so as to judge the quality of the lubricating oil during use.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device and a detection method for lubricating oil inside a gearbox, and belongs to the field of gearboxes. Background technique [0002] Gearboxes are widely used in commonly used machinery. The gearbox is used to transmit power or control the speed. It is relatively stable in work and can adapt to the needs of different environments. [0003] The condition of the lubricating oil inside the existing gearbox cannot be detected in time during use. If the internal gears are damaged or the lubricating oil is polluted, there are many impurities inside, which cannot be found in time, which will affect the work of other normal gears and reduce the The service life of the gear is shortened, and the safety of the gearbox in use cannot be guaranteed. When detecting lubricating oil, it is necessary to discharge the lubricating oil from the gearbox, which is inefficient and cumbersome to op...
