The machining method of the small-module gear has the beneficial effects that: compared with the prior art, the machining method has high machining efficiency and high precision, the manufacturing cost is markedly lowered, and the method has the advantages of easiness in machining, simpleness in operation and the like.
Description
Technical field
The present invention relates to the gear machining technology field, especially a kind of processing method of fine module gear.
Background technology
At present, when processing fine module gear in the prior art, generally all adopt the pinion cutter identical to process with the modulus of processed fine module gear; This traditional fine module gear processing method; Its shortcoming is: when adopting the pinion cutter identical with the modulus of fine module gear to process fine module gear, because the cutter tooth strength ratio of little modulus pinion cutter is lower, therefore when the processing fine module gear; Be easy to occur the impaired situation of pinion cutter, so its processing and operation compare all difficult; In addition, the processing that is used to process the needed little modulus pinion cutter of fine module gear is also difficult, because little modulus pinion cutter tooth root and tooth top point very all; Teeth groove is narrow; Particularly during grinding, roll flute emery wheel profile of tooth is point very, and the abrasive grinding wheel shaped portion is difficult; And in grinding process, be easy to occur sand grains and collapse to fall to come off, be difficult to guarantee the uniformity of institute's roll flute shape; Simultaneously, owing to receive the restriction of gear grinding machines model and processing specification, can't carry out the roll flute processing of close-toothed pinion cutter, the domestic especially at present gear grinding machines that still do not have processing less than 0.1 modulus pinion cutter can't solve the roll flute processing problems less than 0.1 modulus pinion cutter.Therefore, existing fine module gear processing method still can not meet the needs of production.
Summary of the invention
In order to overcome above defective, the technical problem that the present invention will solve is: propose a kind of simple to operate, handling ease and the high fine module gear processing method of machining accuracy.
The technical scheme that the present invention adopted is: a kind of processing method of fine module gear; Gear is fixed on the main shaft of gear shapping machine, the modulus of pinion cutter is greater than the modulus of processed pinion, and the number of teeth of pinion cutter is less than the number of teeth of processed pinion; Pinion cutter rotary feed 0.05-0.5mm/stroke; Radial feeds 50-300mm/min, wherein, the modulus of said pinion cutter is 5-8 a times of processed pinion modulus; The number of teeth of processed pinion be pinion cutter the number of teeth 5-8 doubly, cooperate the circumference and the radial feeds of pinion cutter that pinion is processed.
According to another preferred embodiment, a kind of processing method of fine module gear comprises that further the modulus of said processed fine module gear is 0.6-0.8.
According to another preferred embodiment, a kind of processing method of fine module gear comprises that further the number of teeth of said processed pinion is the 100-200 tooth.
The invention has the beneficial effects as follows: the present invention compared with prior art, working (machining) efficiency is high, precision is high, and manufacturing cost significantly reduces, this method has handling ease, simple operation and other advantages.
The specific embodiment
In conjunction with the preferred embodiments the present invention is done further detailed explanation now.
The present invention relates to a kind of processing method of fine module gear, gear is fixed on the main shaft of gear shapping machine, the modulus of pinion cutter is greater than the modulus of processed pinion; The number of teeth of pinion cutter is less than the number of teeth of processed pinion, pinion cutter rotary feed 0.2mm/stroke, radial feeds 100mm/min; Wherein, the modulus 0.8 of said pinion cutter, processed pinion modulus is 0.1; The number of teeth of processed pinion is 200 teeth, and the number of teeth of pinion cutter is 25 teeth, cooperates the circumference and the radial feeds of pinion cutter that pinion is processed; For pinion cutter, be very easy to processing like this, the present invention compared with prior art, working (machining) efficiency is high; Precision is high, and manufacturing cost significantly reduces, and this method has handling ease, simple operation and other advantages.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
