Abstract

The invention discloses a wind generating set transmission system with the damping function. The wind generating set transmission system comprises an impeller and a main shaft. The front end of the main shaft stretches into the hub of the impeller. The hub of the impeller is internally provided with an annular elastic damping disc with which the main shaft is sleeved. A groove surrounding a disc plane by one circle and provided with the U-shaped cross section is formed in the middle of the disc plane of the elastic damping disc in the axial direction in an inward-concave mode, the inner circumference of the elastic damping disc is provided with an inner assembling end face turned outwards, the outer circumference of the elastic damping disc is provided with an outer assembling end face turned outwards, the main shaft is provided with a protruding ring, the outer surface of the inner assembling end face is closely attached to the inner side face of the protruding ring, the outer surface of the inner assembling end face is connected with the inner side face of the protruding ring, the inner surface of the outer assembling end face is closely attached to the outer end face of the hub of the impeller, the inner surface of the outer assembling end face is connected with the outer end face of the hub of the impeller, and the groove of the elastic damping disc is internally provided with a rubber damping body. The wind generating set transmission system has the advantages that the elastic damping disc deforms to play a role in damping and buffering, reduces loads on the transmission system, reduces the loads borne by a main shaft bearing and enables transmission to be more stable.

Description

technical field [0001] The invention relates to a transmission system of a wind power generating set with a damping function. Background technique [0002] At present, the transmission system of wind turbines is mostly rigidly connected. When the wind turbine is generating electricity, the transmission system directly bears the instantaneous and changeable overturning moment and torque from the impeller. There is no buffer, and the transmission is not stable, which affects the normal operation of the generator set. The main shaft bearing at the front end of the transmission system is under severe stress, which is likely to cause damage to the bearing. Contents of the invention [0003] In order to solve the above technical deficiencies, the present invention provides a wind power generating set transmission system with a shock absorbing function, which can play a buffering role and make the transmission more stable. [0004] The present invention is achieved through the f...
