The invention discloses a design method for obtaining a precise wind power gear ring heater. The precise wind power gear ring heater comprises an induction coil, a magnetizer and a wind power gear ring. The design steps are as follows: measuring the tooth width, tooth height and pressure angle parameters of a single tooth of the wind power gear ring; setting an induction coil structure in initialinduction heating simulation according to the parameters; simulating discretization setting of an induction coil; scanning and heating a wind power gear temperature field by the simulation induction coil; completing heating, and fitting isotherm distribution on a single tooth; extracting an xoy section contour line temperature cloud atlas; judging whether the distance between the temperature isotherm and the tooth profile meets the thickness requirement of the hardening layer or not; circularly heating and storing all values to an array in the judgment process; and according to the design, adjusting structural parameters of the induction coil, and obtaining the single-tooth scanning induction coil with uniform heating and smooth transition. The distance between the induction coil and the wind power gear ring can be automatically matched, the shape of the induction coil is adjusted based on the distance, uniform heating in the tooth profile direction of the wind power gear ring is achieved, and the quality of the wind power gear ring is improved.
Description
technical field [0001] The invention relates to the technical field of induction heating, in particular to a design method for obtaining a precision wind power ring gear heater. Background technique [0002] Due to the clean and renewable characteristics of wind energy and the abundant wind resources in our country, the prospect of wind power generation is broad. Wind power ring gear is an important basic component of wind power generation equipment, and gearbox failure accounts for 12% of wind power system failures, which is about twice the average failure probability of industrial gearboxes. Gear failures account for as much as 55% of wind power gearbox failures. Once a failure occurs, it is difficult to repair and cause the entire unit to fail. The wind power gearbox is not only a relatively high cost part of the whole wind turbine, accounting for about 18% of the total cost of the wind turbine, but also the weak link of the wind turbine. Improving the quality of large-...
