Connector used for wind power generator gear box experimental table

Abstract

The present invention discloses a connector used for a wind power generator gear box experimental table. The connector comprises a coupling, a fixing end base, a cross-axle universal joint extension shaft, a pin, a universal joint rotating arm, a lifting base, a lifting slider, sliding chutes and a shaft-connecting disk. The cross-axle universal joint extension shaft is arranged on the fixing endbase, one end of the coupling is connected with the shaft of a sensor in the experimental table, the other end of the coupling is connected with the cross-axle universal joint extension shaft, and theuniversal joint rotating arm is connected with the cross-axle universal joint extension shaft via the pin. The sliding chutes are arranged in the lifting base, the lifting slider is arranged in the sliding chutes, and the lifting slider can slide up and down in the sliding chutes driven by a lifting mechanism. A second deep groove ball bearing is arranged in the lifting slider, the cross-axle universal joint extension shaft penetrates the second deep groove ball bearing, and the second deep groove ball bearing is connected with the shaft-connecting disk. The shaft-connecting disk is providedwith a plurality of through holes used for connecting input shafts of gear boxes with different sizes. The connector can realize the test of the gear boxes of various types with one experimental table.

Description

technical field [0001] The invention relates to the technical field of wind power generation testing equipment, in particular to a connector used for a wind power generator gearbox test bench. Background technique [0002] At present, as a relatively fast-growing wind power technology, it has gradually entered the vision of various countries. As a clean and renewable energy source, wind power has been included in the national long-term energy development strategy of various countries. A wind turbine is a device that realizes wind power generation. In a wind turbine, the gearbox is one of its core components. Due to the high post-maintenance cost of the gearbox, the test of the gearbox is particularly important. [0003] Gearbox testing requires the use of gearbox test benches. The existing gearbox test benches have certain limitations. The main reason is that the existing test benches can only be limited to testing a certain type of gearbox, but the actual During the test,...

Problems solved by technology

[0003] Gearbox testing requires the use of gearbox test benches. The existing gearbox test benches have certain limitations. The main reason is that the existing test benches can only be limited to testing a certain type of gearbox, but the actual During the test, it is often necessary to test gearboxes of different specifications, but due to the difference in height due to the different specifications of the gearboxes, there will be problems in the connection between the gearbox and the test bench or the test of a gearbox with a large span It is necessary to replace the matching experimental bench, and it is time-consuming and laborious to replace different experimental benches.
