Problems solved by technology

[0002] At present, the test device for the pivot gearbox applied to the dredger mainly relies on imports. Although a similar product was manufactured in China, the test is only a running-in test at a fixed angle, which cannot simulate the actual ship working conditions. The performance not ideal
However, the products imported from abroad have complex structures, inconvenient testing, and high prices, so they cannot be widely used.

Embodiment Construction

[0020] In the actual work of the dredger, the fixed box of the pivotal gearbox is fixed relative to the hull, and the rotating box of the pivotal gearbox is fixedly installed on the bridge frame, and rotates with the bridge frame around the pivot relative to the hull, and the relative rotation angle range is generally 0° ~60°. In the test bench, however, the pivot gearbox rotary box cannot rotate due to the limitation that the hydraulic dynamometer must be fixed. For this reason, according to the principle of relative motion, the technical measures taken by the present invention are: install the rotating box of the pivot gearbox and all the connecting equipment behind it on the fixed base, install the fixed box of the pivot gearbox and all the connecting equipment before it on a swivel base. While the motor transmits power through the pivot gearbox and tests the pivot gearbox, through the cylinder piston, the rotating base and all the equipment on it can rotate 0°~60° around ...

Abstract

This invention disclosed a pivot gear case test-bed which consists of electric motor, flexible coupling, hydraulic clutch, joint slack and fixation case (fixed on the rotating base); rotating case, junction box, acceleration gear case and hydro dynamometer(fixed on the fixation base). The fixation case and rotating case was connected by an axe; one end of steam-cylinder piston was fixed on the fixation base via hinge and the other end was fixed on the rotation base. The structure was logically designed and could solve practical problem in dredging circumstance.

Description

technical field [0001] The invention relates to a marine mechanical transmission device, in particular to a pivot gearbox test bench. Background technique [0002] At present, the test device for the pivot gearbox applied to the dredger mainly relies on imports. Although a similar product was manufactured in China, the test is only a running-in test at a fixed angle, which cannot simulate the actual ship working conditions. The performance not ideal. However, the products imported from abroad have complicated structure, inconvenient testing, and are expensive, so they cannot be widely applied. Contents of the invention [0003] The present invention provides a pivotal gearbox test bench for overcoming the above-mentioned shortcomings existing in the prior art. The pivotal gearbox test bench can carry out various tests on the pivotal gearbox and the pivotal gearbox by using the present invention. Shaft gearbox for experimental research. [0004] The technical scheme adop...
