Abstract
The invention discloses a rotational supporting assembly for a gearbox test bench of a wind generating set. The rotational supporting assembly comprises a hollow shaft, wherein one end of the hollow shaft is connected with an expansion connecting sleeve through a transmission flange; the internal hole surface of the expansion connecting sleeve is matched with a high-speed output shaft of a gearbox for expansion; a rotational oil seal assembly is arranged between the hollow shaft and the high-speed output shaft of the gearbox; a rear end sealing cover is arranged on the rear enclosure of the hollow shaft and is connected with the gearbox; a bearing sleeve is arranged between the hollow shaft and the rear end sealing cover; and bearings are arranged between the bearing sleeve and the hollow shaft. The rotational supporting assembly of the gearbox test bench of the wind generating set provided by the invention adopts the two bearings reasonably, so that the design requirements on high bearing capacity and high transmission torque can be met; a forcible splash lubricating way and a cooling system distributed reasonably are adopted for lubrication, therefore, the service lives of the bearings can be effectively ensured; and as the expansion connecting sleeve is connected with the output shaft of the gearbox, the rotational supporting assembly is good in centering performance, high in bearing capacity and large in transmission torque, meets the requirement on the frequent disassembly of the gearbox, and has an auxiliary seal effect.
Description
[technical field]
The present invention relates to a kind of rotary support assembly of gear box test bed of wind generating set.
[background technique]
Wind-driven generator group wheel box is as the crucial weak element of wind power generating set, from its design and develop, the aspects such as the authentication of quality control, type and customer demand all necessarily require gear-box correlated performance parameter is tested, whether satisfy re-set target with checking, and the rotary support component design is as the gear box test table important component part, for the gearbox high-speed output shaft provides support, transmitting torque and sealing function requirement.So propose this compact type wind power generating set 6.0 MW class gear box test table swivel assembly structural design schemes.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art part, a kind of long service life is provided, load capacity and transmitting torque are large, and centering property is good, quick detachable, and have the rotary support assembly of the gear box test bed of wind generating set of fine seal lubrication performance.
The object of the present invention is achieved like this:
