Automatic measuring system for abrasion of gear reducer

Abstract

The invention belongs to the field of automatic measurement control, and specifically relates to an automatic measuring system for abrasion of a gear reducer. The system is characterized in that the duckbill design is adopted in an outer lubricating oil circulating process; when mixed liquid of the lubricating oil and abrasive dust flows to a rotating outer cylindrical separating drum, the abrasive dust is adsorbed to the surface of the outer cylindrical surface through adsorption power of inner cylindrical surface of a permanent magnet field; when the adsorbed abrasive dust arrives at the lower part as the outer cylindrical separating drum rotates, an inner magnetic field is removed, and the abrasive dust is guided into a planar container under the effects of gravity, centrifugal force, ultrasonic wave and a dust scrapping device; the abrasive dust at the bottom part of the planar container attracts a magnet adhered to the upper part of a magnetic-electric converter, and thus the pressure of a strain transducer is changed; the change of the pressure of the strain transducer leads to the change of output voltage of the strain transducer, so that the abrasion of the reducer can be measured. According to the system, the measurement is automatically carried out, so that the system is of important significance in monitoring the abrasion of the gear reducer, improving the working efficiency of mechanisms, and prolonging the service lives of the mechanisms.

Description

technical field [0001] The invention belongs to the field of automatic measurement and control, and in particular relates to the measurement of wear in the working process of a gear reducer, in particular to an automatic measurement system for the wear of a gear reducer. Background technique [0002] Gear reducers are common equipment in various machinery and machines. Generally, reducers have three working stages: running-in period, normal working period and excessive wear failure period. During the running-in process of the new reducer, more wear and shedding debris (mainly iron and iron alloy, referred to as wear debris) will be generated; when the reducer passes the run-in period, the amount of wear debris will decrease instead, and it will enter the normal optimal working period ; When the reducer runs to the failure period, due to the high pressure and high-speed sliding grinding of the gear working surface, under the local high temperature condition, the tooth surface...
