Embodiment
[0053] Such as figure 2 Shown: In order to achieve the above purpose, a design method for obtaining a precision wind power ring gear heater, the device relied on includes a V-shaped induction coil with a symmetrical left and right structure, a magnetic conductor arranged at the tip of the V-shaped corner of the induction coil, and a heated Wind power ring gear; the induction coil is placed between the two teeth of the wind power ring gear, parallel to the end face of the wind power ring gear and at the same distance from the flanks of the two teeth;
[0054] Such as figure 1 As shown, the following steps are also included:
[0055] 1) Measure the wind power ring gear that actually needs to be heated, and obtain the wind power ring gear parameters: single tooth width, tooth height, pressure angle;
[0056] 2) Set the induction coil structure in the initial induction heating simulation according to the parameters of the wind power ring gear; specifically include:

The invention discloses a design method for obtaining a precision wind power ring gear heater, which includes an induction coil, a magnetizer and a wind power ring gear; the design steps are as follows: measuring the single tooth width, tooth height, and pressure angle parameters of the wind power ring gear; according to the parameters Set the induction coil structure in the initial induction heating simulation; simulate the discretization setting of the induction coil; simulate the induction coil to scan and heat the wind power gear temperature field; complete the heating and fit the isotherm distribution on the single tooth; extract the contour temperature cloud map of the xoy section; judge the temperature Whether the distance between the isotherm and the tooth profile meets the requirements of the thickness of the hardened layer; cyclic heating and the above judgment process save all values to the array; design and adjust the structural parameters of the induction coil based on this, and obtain a single-tooth scanning induction coil with uniform heating and smooth transition. The invention can automatically match the distance between the induction coil and the wind power ring gear, adjust the shape of the induction coil based on this, realize uniform heating in the tooth profile direction of the wind power ring gear, and improve the quality of the wind power ring gear.
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-...
