An end-connecting type hydraulic loader to solve the difficult loading and assembly on the same side in closed power closed testing in planetary gearbox, includes a transmission shaft (), an internal output inner gear sleeve () on a left end of the transmission shaft (), a thrust shaft () rotatably mounted on the transmission shaft () and positioned on a right side of internal output inner gear sleeve (), an external output inner gear sleeve () coaxially installed on the internal output inner gear sleeve () and connected to the thrust shaft (), a spiral floating cylinder () on a right end of the thrust shaft () and a siding assembly on the transmission shaft () meshed with the spiral floating cylinder () having a left and right sliding movement along the transmission shaft () under a hydraulic oil circuit action of the transmission shaft.

End-connecting type hydraulic loader

A high-power and heavy-load back-to-back planetary gear test bench for full speed and full loading testing, which solves transmission shaft's high processing cost problem and the inability to test in a simulated environment, includes a driving device, first and second shaft couplings, a speed increaser, a speed and torque meter, a back-to-back planetary gearbox closed power system, a clamping groove body coaxially sleeved on an axial positioning protrusion, a clamping component embedded inside an axial positioning groove, and a shaft segment coaxially installed on the clamping groove body to provide an axial displacement by the clamping component to tightly clamp the clamping groove body and the axial positioning protrusion, therefore the clamping groove body generates a radial displacement under an axial pushing of the clamping component and is expanded in the radial direction to tightly connect with the axial positioning groove; and a marine test component for marine environment simulation.

High-power and heavy-load back-to-back planetary gear test platform

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.
