Abstract
The invention relates to a machining method of a wind power generation yawing gear ring, relates to the field of machining, in particular to a machining method of a wind power generation yawing gear ring. The machining method comprises the following steps of blanking; roughly turning; tempering a workpiece; semi-finish turning, removing a majority of machining allowance of a blank, remaining a finish machining allowance of each main machined surface, and turning a secondary machined surface to a needed size; primarily finish machining, to be specific, machining each main surface of the workpiece; nitriding, to be specific, nitriding the workpiece; and removing a nitrided layer on an outer circle and two end surfaces of a tooth part according to a benchmark uniform principle; grinding the upper end surface and the lower end surface of the workpiece; machining a bolt hole on the workpiece, and chamfering a hole end; installing and positioning the workpiece on a gear hobbing machine, machining a gear by selecting an appropriate hobbing cutter, and chamfering the tooth part; nitriding; and surface hardening. The machining method is simple in operation, not only can the production efficiency be improved, but also the production cost can be reduced, and the labor intensity of workers can be alleviated.
Description
Technical field
The present invention relates to field of machining, be specifically related to wind-power generating yaw ring gear machining method.
Background technology
Yawing gear ring is the key components and parts in wind power equipment yaw system, and its effect is equivalent to large-scale bearing.It is positioned at bottom cabin seat, lower end is connected and fixed by bolt and tower cylinder, top supports whole cabin mechanism by sliding surface, around be meshed with four yawing reducer output gears, by the driving of motor of going off course, drive cabin whole mechanism slow circumvolve, to reach the object in adjustment wind electric impeller direction.The projected life of yawing gear ring is generally 20 years, special because of its installation site, in use maintenance difficult, replacement cost are high, so have this part of higher requirement to belong to large-sized annular gear member category to the accuracy of manufacture of this part and quality, material is generally modified steel alloy; According to part instructions for use, outer gear modulus is generally at 10 ~ 20mm, and the flank of tooth requires surface hardening, and hardness General Requirements is at more than 50HRC; Bore design becomes stepped, and wherein the requirement on machining accuracy of endoporus and end face sliding area is higher, and surface requirements nitrogen treatment, hardness General Requirements reaches about 700HV, to improve contact fatigue strength and antiseptic property; Middle subplate Position Design becomes a circle bolt hole, and in order to a conjunction tower drum flange, this place's bolt hole is because quantity is more, so all have higher requirements to screw hole dimensions and position degree.
Processing method in the past, all require very high, and process is loaded down with trivial details to workman and equipment, and production efficiency is low, increases production cost.
Summary of the invention
In order to solve the problem, the invention provides a kind of simple to operate, both can enhance productivity, and can production cost be reduced again, and reduce the wind-power generating yaw ring gear machining method of the labour intensity of workman.
Wind-power generating yaw ring gear machining method of the present invention, comprises the following steps:
The first step, blanking, selects suitable blank material;
Second step, rough turn, carry out rough turn according to processing dimension to blank, remove the major part forging surplus of blank, leave heat treatment process surplus, ensure Part Surface Roughness requirement;
3rd step, heat treatment, carries out modifier treatment to workpiece;
4th step, half finish turning, remove blank major part allowance, each main machined surface stays allowance for finish, and secondary machined surface car is to requiring size;
5th step, first time fine finishining, processes each major surfaces of workpiece, notes the selection of datum level in process;
6th step, nitrogenize, carries out nitrogen treatment to workpiece;
7th step, second time fine finishining, according to unifying datum principle, car falls the nitration case of teeth portion cylindrical and both ends of the surface;
8th step, carries out grinding process to the upper and lower side surface of workpiece, meets surface roughness requirements;
9th step, on data drilling machine, processes the bolt hole on workpiece, nose end chamfering;
Tenth step, on gear-hobbing machine, carries out Set and Positioning to workpiece, selects suitable hobboing cutter, process gear, and carry out chamfered to teeth portion;
11 step, heat treatment, Nitrizing Treatment;
12 step, heat treatment, surface hardening.
Preferably, the tenth step is installed on nipper base on gear-hobbing machine must know burr, and wiped clean, tooth base and locating surface are fitted tightly, and uses centimeter check installation accuracy.
The present invention is simple to operate, both can enhance productivity, and can reduce production cost again, and reduces the labour intensity of workman.
