BENCH FOR TESTING OF TOOTH GEARS ALONG CLOSED CIRCUIT Russian patent published in 2014 - IPC G01M13/02 

FIELD: testing equipment.

SUBSTANCE: bench comprises a drive, input and output shafts for installation of master and slave wheels of tooth gears with identical gear ratio accordingly, a loader connected to the shaft. The drive and the input shaft are connected with a pin coupling, master and slave wheels of two tested gears accordingly are installed onto inlet and outlet shafts. At the same time one of the shafts is made in the form of two hollow half-shafts, and the loader is made in the form of a torsion and a transverse-screw cap, one half-coupling of which is rigidly fixed on the outer end of one hollow half-shaft, and its second half-coupling is rigidly fixed with a torsion end protruding from the same hollow half-shaft, which is arranged inside hollow half-shafts and is rigidly fixed by one end on the outer end of the other hollow half-shaft. At the same time the bench is equipped with a thermometer and diagnostic equipment, and the drive is equipped with a current and voltage sensor and a device for measurement of frequency of motor rotation.

EFFECT: simplified design, increased volume of information, produced in process of measurements, complex evaluation of factors that impact capacity losses in a tooth gear.
