SU1580203A1 - Bed for testing motor-reduction gears - Google Patents

Abstract

The invention relates to mechanical engineering, namely, to measuring equipment, and can be used when running and testing one pair of gear motors. The aim of the invention is to expand the technological capabilities by reducing the labor intensity in adjusting the load and at the same time simplifying the installation and controlling the magnitude of the load during the testing process. During operation, the load is created by supplying compressed air to the working cavities of the pneumatic cylinder 31, which turns the carrier 16 fixed on the central shaft 15 and providing, through the gear system with external teeth, the relative rotation of the output shafts 13 and 14 of the planetary gear and thereby loading the gear motors under test. . The magnitude of the load is controlled by the meter 4 of the load through the slider 40 and the two shoulders levers 41, 42. 5 Il.

Claims (1)

Claim A test bench for gearmotors, containing a base, a planetary gear mounted on it, having a housing, gears, and two output shafts designed for kinematic connection with the tested gearmotors, and a reversing loading device, including a double-acting power cylinder, distinguishing - with the fact that, in order to expand technological capabilities, the output shafts of the planetary gear are made parallel, the gears are cylindrical with external teeth, the planetary gear in It also includes a central shaft parallel to the output shafts and a carrier attached to the last one with axles parallel to the central shaft, two pairs of spur gears are fixed on the axles of the carrier, the third pair is mounted on the output shafts, the fourth pair is mounted for rotation on the central shaft, one of the wheels of the first two pairs are engaged with each other, the other with the wheels of the fourth pair, the latter are also engaged with the wheels of the third pair, the reversing loading device also includes articulated f with a rod of the power cylinder, a rocker arm, one arm of which is hinged-j but connected to the carrier, a slider pivotally connected to the second step of the rocker arm mounted in the planetary gear housing with the possibility of moving parallel to the rod of the power cylinder, and two-arm levers pivotally connected to the planetary gear housing some shoulders of which have the ability to interact with the ends of the slider, and the stand is equipped with a load meter, kinematically connected with the other shoulders of the two-arm levers. 1 Zida Fig.Z Compiled by Yu.Krasnenko Editor N.
