Abstract

The utility model discloses a closed axial loading test apparatus of a helical gear thrust cone balancing device. The apparatus comprises a motor, a test gear box comprising an input shaft and an output gear, an accompanied test gear box comprising the input shaft and the output gear, a coupling, a torque loader and a hydraulic axial thrust loader. The axial thrust loader is mainly formed by an outer sheath of the loader, box bodies and a rolling bearing. During the test, the motor is started so that gear apparatuses in the two box bodies carry out transmission and simultaneously the loader is used to generate a pair of relative torques to end portions of output shafts in the two box bodies. At this time, an elastic shaft and other parts generate elastic torsion and torsional deformation is generated. The accompanied test gear box and the test gear box transmit the torque so as to realize power enclosing. Pressure oil is entered into an oil chamber through an oil inlet channel. A mechanical sealing ring and a rotation sealing ring make the pressure oil do not leak from a joint so that two shaft ends generate the thrust and axial loading is realized to be performed on the thrust cone.
