GEARBOX TEST SETUP Russian patent published in 2023 - IPC G01M1/00 F16H1/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the testing equipment for testing gearboxes. The device consists of a base, with a drive installed on it and support elements for installing the gearbox under test, and a loader located inside the base. In this case, the base additionally contains a tabletop on which a rack is mounted, which is a column, and the drive is placed on the console of the rack and includes an electric motor mounted on the bearing support of the console, controlled by a frequency converter, a torque sensor, a cardan transmission, a telescopic shaft with a splined shank and a drive support installed in the neck of the housing of the gearbox under test. In this case, the console has the ability to rotate relative to the column with a handle, and the loader contains an electric motor operating in generator mode, controlled by a frequency converter, and a gearbox designed to increase the load torque created by the electric motor. The connection of the loader with the output shaft of the gearbox under test is carried out using a gear movable coupling connecting the shaft of the loader gearbox and a spring-loaded drive head that engages with the output shaft of the gearbox under test under the influence of a set of springs and a rod connected to an automatic spring-loaded gear coupling through a lever. The rod shank interacts with an inductive switch, which ensures that the drive motor turns on at a reduced speed in the absence of engagement.

EFFECT: providing the ability to test the gearbox idle, under load, simulating the real operation of the gearbox with different frequency characteristics of loads with high reliability and minimal labor intensity.
