Abstract
The present invention discloses a method for processing a fine module gear. When a gear shaper cutter is adopted for processing the fine module gear, the modulus of the adopted special gear shaper cutter is greater than that of the fine module gear, that is to say the modulus of the adopted special gear shaper cutter is 2 to 10 times greater than that of the fine module gear, and the number of teeth of the adopted special gear shaper cutter is an integer number of teeth which is 2 to 10 times smaller than the number of teeth of a required standard gear shaper cutter of the processed fine module gear. After that according to a conventional method, the number of teeth of the desired standard gear shaper cutter of the processed fine module gear is used as the parameter of a corresponding cutter matched with a tooth-separating change gear of a processing machine tool; thus, the tooth shape addendum part of the special gear shaper cutter can be adopted as the tooth shape of the effective cutter to gear shaping process the fine module gear. When used for processing the fine module gear, the present invention has the advantages of simple operation and easy processing.
Description
Technical field:
The present invention relates to a kind of processing method of fine module gear, belong to the gear machining technology field.
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 are all very sharp, teeth groove is narrow, particularly during grinding, roll flute emery wheel profile of tooth is very sharp, 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 be subjected to 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:
The objective of the invention is: provide a kind of processing method of fine module gear of simple to operate, handling ease, to overcome the deficiencies in the prior art.
The present invention is achieved in that it comprises employing pinion cutter processing fine module gear, when adopting pinion cutter processing fine module gear, the modulus of the special pinion cutter that is adopted is greater than the modulus of processed fine module gear, promptly the modulus of the special pinion cutter that is adopted is 2～10 times of processed fine module gear modulus, and the number of teeth of the special pinion cutter that is adopted is 1/1/2nd～10th the integer number of teeth of the required standard pinion cutter number of teeth of processed fine module gear, then according to the number of teeth of the conventional method standard pinion cutter that processed fine module gear is required corresponding cutter parameters as collocation machining tool divided teeth gear, the profile of tooth tooth top part that can adopt this special pinion cutter is like this come the Gear Shaping fine module gear as the effective profile of tooth of cutter; The modulus of processed fine module gear is not more than 0.5.
Owing to adopted technique scheme, the present invention compared with prior art because pinion cutter greater than the fine module gear modulus of the present invention has the advantage of intensity height, handling ease, therefore, when adopting the present invention to process fine module gear, has advantage simple to operate, handling ease.
The specific embodiment:
Embodiments of the invention: for example processing modulus is 0.08, when the number of teeth is the fine module gear of 262 teeth, the modulus of the standard pinion cutter that it is required should be 0.08, the number of teeth is 250 teeth, but because modulus is 0.08 the very difficult processing of pinion cutter, be subjected in addition gear grinding machines the processing specification restriction and can not process, thereby in the present embodiment, the modulus of processing the special pinion cutter of this fine module gear is defined as 0.4, the number of teeth of this special pinion cutter is defined as 50 teeth, like this, this special pinion cutter just is easy to processed with respect to the pinion cutter of 0.08 modulus, be that available this special pinion cutter is processed this fine module gear then, when processing fine module gear with this special pinion cutter, the calculating of its Gear Shaping divided teeth gear is carried out gear shaping by the number of teeth 250 teeth calculating of standard pinion cutter, can adopt the profile of tooth tooth top part of this special pinion cutter to come Gear Shaping to go out this fine module gear as the profile of tooth of effective cutter like this.
Claims (2)
1, a kind of processing method of fine module gear, it comprises adopts pinion cutter processing fine module gear, it is characterized in that: when adopting pinion cutter processing fine module gear, the modulus of the special pinion cutter that is adopted is greater than the modulus of processed fine module gear, the modulus of special pinion cutter is 2～10 times of processed fine module gear modulus, and the number of teeth of the special pinion cutter that is adopted is 1/1/2nd～10th the integer number of teeth of the required standard pinion cutter number of teeth of processed fine module gear, then according to the number of teeth of the conventional method standard pinion cutter that processed fine module gear is required corresponding cutter parameters as collocation machining tool divided teeth gear, the profile of tooth tooth top part that can adopt this special pinion cutter is like this come the Gear Shaping fine module gear as the effective profile of tooth of cutter.
2, the processing method of fine module gear according to claim 1 is characterized in that: the modulus of processed fine module gear is not more than 0.5.
