Abstract

The invention discloses a component for combining a bearing pedestal and a front frame and a wind generating set. The component comprises a front frame portion and a bearing pedestal portion which areintegrally cast. The front frame portion comprises a top plate, a bottom plate, and a first supporting portion, a second supporting portion and a third supporting portion which are located between the top plate and the bottom plate. The top plate is provided with a first end portion, a second end portion opposite to the first end portion, a first side portion, and a second side portion opposite to the first side portion. The bearing pedestal portion is located at the first end portion of the top plate. The first supporting portion and the second supporting portion are used for supporting thefirst side portion and the second side portion of the top plate correspondingly. The third supporting portion is used for supporting the middle of the top plate. The component adopts a three-fulcrum (the first supporting portion, the second supporting portion and the third supporting portion) carrying structural form, the using amount of materials is greatly reduced and the weight is lowered whilethe strength and stability of the component are guaranteed, meanwhile, the third supporting portion is the main connection section and adopts circular arc transition and a thin-walled structure, force transmission is guaranteed, and furthermore, the materials are efficiently utilized.

Description

technical field [0001] The invention relates to the field of wind turbines, in particular to a component combining a bearing seat and a front frame and a wind turbine. Background technique [0002] The bearing seat and front frame of the existing wind turbine are the core components in the nacelle, and the two structural parts are connected by high-strength bolts, such as figure 1 shown. The two work together to fix the drive chain and connect structural parts such as the gearbox, wheel hub and rear frame. Casting molds are often prefabricated before castings are manufactured, and bearing housings and front frames are large castings. Their shape, structure and weight not only determine their own cost, but also play a decisive role in the production and manufacture of casting molds. [0003] At present, the design of most mechanical parts is mostly based on the design experience of engineers, and there is no clear direction for the force of the parts at the beginning of the...
