Megawatt level mechanical total power sealed gear test-bed

Abstract

The invention discloses a megawatt level mechanical total power sealed gear test-bed which solves problems that investment is large, energy consumption is serious, assembling and use requirements are influenced as a position of a structure is fixed when a performance and a service life of a megawatt level speed reducer are tested by using a conventional electric power sealed gear test-bed. An input end of a primary test speed reducer is connected with an input sensor; an input end of a secondary test speed reducer is connected with an output sensor; at least one pair of right angle gear boxes are connected in series between the input sensor and the output sensor; a mechanical loader is arranged between the two right angle gear boxes; the right angle gear boxes are connected with the mechanical loader through a transmission shaft; and an input end of any one of the right angle gear boxes is connected with a motor. Through a reasonable design, thereby overcoming the problems that the conventional electric power sealed gear test-bed has larger investment and serious energy consumption; power for driving the motor is reduced to be about 1 / 10 that of an original power; cost is reduced, and at the same time, a test effect is improved; and the test-bed has the advantages of simple structure and convenience in operation.

Description

Technical field [0001] The invention relates to a mechanical test device, in particular to a megawatt-class mechanical full-power enclosed gear test bench. Background technique [0002] The megawatt-class mechanical full-power enclosed gear test bench is a test device used in the machining industry to test the strength and life of the gears of the megawatt reducer. [0003] At present, the electric power enclosed gear test bench is mostly used for the testing of megawatt-level reducers. The electric power enclosed gear test bench adopts a modular structure. Through different combinations and evolution, the performance test and life test of different types of reducers can be realized on the same test bench. [0004] The electric power enclosed gear test bench includes the main test reducer and the auxiliary test reducer. The output shafts of the main test reducer and the auxiliary test reducer are connected through a coupling, and the input shaft of the main test reducer is connected ...
