Abstract
The invention discloses a method for controlling toothed gear shaving modification quality so as to solve the problem that difficulty on control over toothed gear shaving modification quality in the prior art is high. The method includes the steps that coordinate points corresponding to the tooth profile spread length and the tooth direction are obtained by utilizing a tooth profile detection chart and a helical line detection chart respectively combined with quality requirements, a K-shaped control chart is drawn on a toothed gear measurement center according to the coordinate points; actual tooth profile measuring traces of the tooth profile and tooth direction of the toothed gear after shaving modification are compared with the K-shaped control chart, if the actual tooth profile measuring traces are within the K-shaped control chart, shaving is qualified, and if the actual tooth profile measuring traces are out of the K-shaped control chart, shaving is unqualified. By means of the method for controlling toothed gear shaving modification quality, whether shaving is qualified or not can be judged visually.
Description
Technical field
The present invention relates to a kind of static measurement method of gear quality.
Background technology
Along with the raising that people require the car comfortableness, each Automotive producer is also more and more higher to the quality requirements of saloon car transmission gear.In order to reduce transmission gear transmission noise, all can carry out correction of the flank shape to tooth top, the tooth root of gear, the noise produced to eliminate the gear meshing interference.The standard detected due to the gear metering is the standard involute urve, and the standards for gear accuracy of gear metering output comprises following several: fH α (flank profil inclination tolerance), ff α (profile geometry tolerance), F α (flank profil gross tolerance) and fH β (helix inclination tolerance), ff β (helix shape tolerance), F β (helix gross tolerance).These standards one are that data are various, the 2nd, be all for the difference that departs from the standard involute urve, particularly to tooth top, tooth root tip relief and increment tip relief can't be visual in image therefore judge that the more difficult judgement of workman, technician and metrological personnel can not be guaranteed gear shaving correction of the flank shape quality.
Summary of the invention
The invention is intended to provide a kind of control method of gear shaving correction of the flank shape quality, to solve the higher problem of prior art middle gear modification shaving quality control difficulty.
The patent scheme: the control method of the gear shaving correction of the flank shape quality in this programme is characterized in that comprising the steps:
A) tolerance of using flank profil detection figure and helix detection to scheme bond quality requirement respectively provides profile of tooth length of run and coordinate points corresponding to teeth directional;
B) draw out K shape control chart according to its coordinate points on gear measuring center;
C) practical tooth of the tooth-formation of gear after modification shaving, teeth directional metering trace and K shape control chart are contrasted, need only in K shape control chart, shaving is qualified, if outside K shape control chart shaving is defective.
The applicant requires to formulate K shape figure control criterion according to the form of gear tooth, axial modification.Use K shape control chart to provide profile of tooth length of run and coordinate points corresponding to teeth directional, the gauger draws out K shape control chart as evaluation criteria according to its coordinate points on gear measuring center.Tooth-formation of gear after modification shaving, the practical tooth of teeth directional metering trace are as long as in K shape control chart, and shaving is qualified, outside K shape control chart, is defective, makes it to be judged very visual in imagely.After using this technology, the correction of the flank shape quality of gear has obtained stable control, and gear quality has obtained large increase.
Further, described flank profil detects figure as shown in Figure 1, and helix detects figure as shown in Figure 2, in Fig. 1

The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
The flank profil detection figure that Fig. 1 is the embodiment of the present invention.
The helix detection figure that Fig. 2 is the embodiment of the present invention.
The K shape control chart that Fig. 3 is the embodiment of the present invention.
Embodiment
The technical requirement of shaving profile of tooth, teeth directional being repaiied to type is: gear tooth width is 15.3.
Flank profil inclination tolerance fH α=0.004～0.012, profile geometry tolerance ff α=0.002, flank profil gross tolerance F α=0.012, gear length of run 4.41 place's tooth root profiling quantities 0.004～0.012, length of run 15.639 place's tooth top profiling quantities 0.003～0.008.
Helix inclination tolerance fH β=0.009～0.011, helix shape tolerance ff β=0.0075, helix total departure F β=0.011, facewidth two ends remove width 10% after, its helix cydariform amount C β=0.006～0.008.
Tooth pitch accumulation gross tolerance Fp=0.026, gear ring diameter run-out=0.025.The initial workpiece gear can be processed after sending the measuring room metering qualified.
At first require to formulate K shape figure control criterion according to the form of gear tooth, axial modification, as depicted in figs. 1 and 2, use K shape control chart to provide profile of tooth length of run and coordinate points corresponding to teeth directional.
The explanation of Fig. 1:
The explanation of Fig. 2:
Then the gauger draws out K shape control chart as evaluation criteria according to its coordinate points on gear measuring center.
Finally, after gear completes modification shaving, by Klinglnberg P Series Gear measuring center (concrete model can be chosen P26), the practical tooth of teeth directional metering trace and K shape control chart are contrasted, as shown in Figure 3, if trace in K shape control chart shaving is qualified, otherwise as outside K shape control chart, be defective, make it to be judged very visual in imagely.After we use this technology, the correction of the flank shape quality of gear has obtained stable control, and gear quality has obtained large increase.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic are not done too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
