Abstract

The invention discloses a general gear pair service life test board, which comprises a driving motor, an input bearing support, an input torque sensor, an input main shaft and a coupler for connectingthe driving motor, the input bearing support, the input torque sensor and the input main shaft, wherein the above parts are placed on the input end sliding plate in unified mode; a plastic-coated guide rail is arranged between the input end sliding plate and the marble platform; the moving distance of the input end sliding plate is controlled through a hand wheel, a magnetic grid and a trapezoidal lead screw; a to-be-tested gear is installed in the gear tool clamp; the gear tool clamp is integrally placed in a temperature control box, and a temperature sensor is used for monitoring the surface temperature of a to-be-measured gear in real time. The gear tool clamp is connected with the input main shaft and the output main shaft through couplers. The load motor, the output torque sensor, the output bearing support and the output main shaft are directly placed on the marble platform. The test board is simple in structure and convenient to clamp the gear, and gear measuring time can be greatly saved. Under the condition of full-load operation, the abrasion condition of the to-be-measured gear is tested in a short time, and the service life is reliably evaluated.

Description

technical field

[0001] The invention relates to a universal gear life tester, which belongs to the fields of precision test and measurement technology, precision instruments and mechanical transmission. Background technique

[0002] Since entering the 21st century, gears have been widely used in the transmission system of mechanical equipment, and the service life of the gear system directly affects the service life of the entire equipment. If the service life of the gear system does not meet expectations, it will cause huge losses to the entire production and society. Therefore, the life prediction of gears plays an important role in industrial production.

[0003] Existing gear products usually need to ensure that they can run for more than 70000h under actual working conditions based on the needs of customers. However, based on the development cycle and conditions, it is impossible for domestic and foreign manufacturers to fully restore them during specific product testi...
