A multi-level worm wheel blade adjustment mechanism

Abstract

The invention relates to the technical field of wind power generation equipment, in particular to a multilayer worm-and-gear wind turbine blade adjusting mechanism to solve the problems that an adjusting mechanism in the conventional toothed wheel technology requires a large torque on the adjusting mechanism, the adjusting mechanism is poor in reliability, and a blade angle is difficult to control. The multilayer worm-and-gear wind turbine blade adjusting mechanism comprises worm toothed wheel seats, outer layer supporting frames, engine room cylinder walls, a driving motor fixing disk, a toothed wheel mechanism and a worm-and-gear mechanism; the engine room cylinder walls are connected with the driving motor fixing disk; the worm toothed wheel seats are mounted on the engine room cylinder walls; the outer layer supporting frames are uniformly mounted on the outer sides of the worm toothed wheel seats; four transmission toothed wheels are assembled surrounding a main driving toothed wheel from inside to outside and are engaged sequentially; inner layer gears are mounted at the end parts of blade shafts on the inner sides of the worm toothed wheels seats; and outer layer gears are mounted at the end parts of blade shafts on the inner sides of the outer layer supporting frames. Through changing the structure of the adjusting mechanism and the transmission mode, the transmission stability and the accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a multi-level worm wheel and worm type wind wheel 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 angle of each blade. 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 patent ZL201420608931.5 is also not ideal in terms of blade angle control. As a result, the overall operation and unit power generation cost are still unsatisf...

AI Technical Summary

Problems solved by technology

The blade angle is independently adjusted and the synchronization is poor

[0004] In addition, the gear structure of a single-frame impeller disclosed in the invention patent and utility model patent ZL201420608931.5 of the invention patent application number 201410561011.7 is not ideal in terms of blade angle control

As a result, the overall operation and unit power generation cost are still unsatisfactory
