Straight rack type wind turbine blade adjusting mechanism

Abstract

The invention relates to the technical field of wind power generation equipment, in particular to a straight rack type wind turbine blade adjusting mechanism to solve the problems that the adjusting mechanism in the existing gear wheel technology is poor in reliability, a large torque of the adjusting mechanism is required, and a blade angle is difficult to control. The straight rack type wind turbine blade adjusting mechanism comprises a driving motor fixed disk, an engine room cylindrical wall, a rack fixed front disk, a rack fixed rear disk, a front pressure disk, a rear pressure disk, a gear and rack mechanism, a screw and nut mechanism, three sliding bar bearing pedestals, sliding bar bearings and sliding bars; the front pressure disk is connected on the driving motor fixed disk; the three sliding bar bearing pedestals are uniformly arranged on the rear pressure disk; blade shafts are mounted on the engine room cylindrical wall by bearings; gears are fixed at the end parts of the blade shafts on the inner side of the engine room cylindrical wall and engaged with racks; a nut is fixed in the middle of the rack fixed front disk; and a screw is matched with the nut and connected with an output mechanism of a power unit. According to the straight rack type wind turbine blade adjusting mechanism, by changing the structure of the blade adjusting mechanism and a 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 straight rack 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 part to move, 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 patent ZL 201420608931.5 is 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 invent...
