Abstract

The invention relates to the technical field of wind power generation equipment, in particular to a worm and gear type wind turbine blade adjusting mechanism. In the prior gear art, an adjusting mechanism has the problems that mechanism torque which needs to be adjusted is large, reliability is poor, and blade angles cannot be controlled easily. The mechanism comprises a worm gear base, an engine room cylinder wall, a driving motor fixing disc, a gear mechanism and a worm and gear mechanism. The engine room cylinder wall is connected to the driving motor fixing disc. The worm gear base is arranged on the engine room cylinder wall. A main transmission gear is assembled between the worm gear base and the driving motor fixing disc through a bearing and a bearing base. Two circles of transmission gears are arranged around the main transmission gear. The worm and the outer circle transmission gear are assembled between the driving motor fixing disc and the worm gear base coaxially. A worm wheel is arranged on a blade shaft on the inner side of the worm gear base. By changing the structure of the blade adjusting mechanism, the transmission mode is changed; transmission stability and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a worm gear type wind rotor blade adjustment mechanism. Background technique [0002] The wind turbine blade adjustment mechanism is connected with the power unit to drive the main transmission gear to rotate, and the windward angle of the blade is adjusted through the transmission of the transmission mechanism. [0003] At present, some wind turbine blades are installed at a fixed angle, and some are independently adjusted for the blade angle. The independent adjustment of blade angle is poor in synchronization. [0004] In addition, the gear structure of a single-frame impeller disclosed in the invention patent application number 201410561011.7 and the utility model invention ZL 201420608931.5 is also not ideal in terms of blade angle control. As a result, the overall operation and unit power generation cost are still unsatisfactory. Contents of the ...
