Abstract
A coupling device between a test box and a companion test box for back-to-back planetary testing to solve the problem of axial displacement and motion in the connecting structure of the existing back-to-back planetary test bench, which comprises a first output flange, a second output flange, a first transition coupling gear connected to the first output flange, a second transition coupling gear connected to the second output flange, a ring-shaped toothed flange with internal teeth coupled to the first and the second transition coupling gears, an axial limiting unit installed on the left and right sides of the toothed flange and extends towards the axis of the transmission shaft formed by two semicircular shaped grooved sleeve bodies, a radial limiting ring and screw rods, and an axial compensation groove formed on an inner sidewall of the axial limiting unit.
