No-load test device for overturning of pitch-variable gearbox

Abstract

The invention discloses a no-load test device for overturning of a pitch-variable gearbox. The no-load test device comprises a fixed rack, an overturning station, an air cylinder piston assembly, a balance crane and a driving motor, wherein the overturning station is hinged to the fixed rack through two first hinging shafts, the two first hinging shafts are positioned on the front and rear sides of the overturning station and are centred left and right, the overturning station is articulated with the lower end of a piston rod through a second hinging shaft, the second hinging shaft is positioned on the left side of the overturning station and centred front and back, the upper end of the piston rod extends into an air cylinder body, the upper end of the air cylinder body is hinged to the fixed rack, the lower end of the air cylinder body is suspended, the driving motor is arranged in a lifting frame, the lifting frame is suspended at the lower end of the balance crane, the balance crane is fixedly arranged above the overturning station, and the axes of the first hinging shafts and the second hinging shaft are parallel. According to the no-load test device, the pitch-variable gearbox to be tested can be automatically overturned in a range from 0 degrees to 90 degrees, so that the pitch-variable gearbox can be tested in an approximately real application condition.

Description

technical field [0001] The invention relates to a test device of a gear box, in particular to a no-load test device capable of realizing a 90° overturn of a pitch variable gear box. Background technique [0002] to test as figure 2 As shown in the pitch gearbox 10, the traditional pitch gearbox no-load test bench is fixed and vertically installed, and this test bench can only test the pitch gearbox in a vertical state, such as figure 1 As shown, the tested pitch gearbox 10 and the driving motor 5 are installed on the test bench 11. The main problems are: (1) The tested pitch gearbox 10 cannot be turned over on the test bench 11, and the The actual operating conditions of the pitch gearbox 10 are too different to meet the needs of quality inspection and control; (2) The drive motor 5 is difficult to install, and different types of pitch gearboxes need to be equipped with different types of dedicated drive motors, which is not very versatile . Contents of the invention ...
