Abstract

The invention discloses a transmission chain device of a compact-type wind generating set. The transmission chain device is characterized by comprising a main shaft, an independently arranged main bearing, an engine room seat, a transmission gear box and a power generator, wherein the main bearing is a dual-column conical roller bearing, and is arranged on the main shaft; the main shaft and an inner ring of the main bearing are in interference fit; an outer ring of the main bearing is internally arranged in the engine room seat and is fixedly connected with the engine room seat; the engine room seat which acts as the support seat of the main bearing is in transition fit with the outer ring of the main bearing; two ends of the main shaft are respectively connected with an impellor of the wind generator and an input shaft end of the transmission gear box through a flange; the transmission gear box is fixedly arranged on the engine room seat; the power generator is connected with the transmission gear box through a membrane-type coupler; and the engine room seat is fixed on a tower barrel of the wind power generator. According to the invention, the dimension of the transmission chain is shortened greatly, thus the transmission chain system is lighter in weight, and has smaller volume, lower cost and higher efficiency.

Description

technical field [0001] The invention relates to a transmission device, in particular to a compact transmission chain device of a wind power generating set. Background technique [0002] With the development of the new energy industry, wind energy, which was developed earlier in the new energy, occupies an increasing proportion in the power grid. At the same time, more and more wind turbine manufacturers have developed various wind turbine mainframes. At present, there are two main types: horizontal axis and vertical axis wind turbines. Horizontal axis fans are currently widely used and are the mainstream models for wind power generation. In order to enhance the competitiveness of the product in the market, from the improvement of the design of the transmission chain to the consideration of the different functions of various components, they have become different considerations for the design improvement of the main engine of the wind turbine. [0003] According to the work...
