Description
Technical field
The present invention relates to a kind of field of gears, specifically a kind of teeth directional unsymmetric shape modification measures the processed and applied side of gear
Method.
Background technology
With the application of the raising of automatic transmission gear required precision, particularly profile modifying gear, gear engagement registration
It is higher and higher.Existing profile modifying gear is mostly unsymmetric shape modification, and profiling quantity is bigger, and detects tooth to diversified development
The measurement gear of wheel precision is always standard tooth form, standard teeth directional, and the gear of big axial modification, the entire facewidth are detected with its engagement
Direction cannot completely attach to, and there is sideshake in part facewidth direction, therefore has the product defects of sideshake part, the measurement tooth of standard
Wheel can not detect.
Invention content
For big profile modifying gear double engagements detection have sideshake, sideshake regio defect can not be detected the technical issues of, now carry
For a kind of measurement gear of teeth directional unsymmetric shape modification to solve above-mentioned technical problem.
Specially following technical solution：
The processing method that a kind of teeth directional unsymmetric shape modification measures gear, includes the following steps：
1) by the number of teeth of tested gear, the facewidth, tip diameter, root diameter and measure gear installation center away from will
It asks, the number of teeth of corresponding design measurement gear, the facewidth, tip diameter, root diameter；
2) according to the axial modification requirement of tested gear, b and △ X are measured, and calculate according to formula tan △ β=△ X/b
Helical angle correction of the flank shape angle △ β, wherein b are facewidth size, unit mm；△ X be profiling quantity size, unit mm；△ β are spiral
Angle correction of the flank shape angle, unit are °；
3) by the helical angle correction of the flank shape angle △ β in step 2) reversed roll flute is carried out to measuring gear.
As further embodiment of the present invention：The profiling quantity size △ X >=0.02mm.
As further scheme of the invention：The meshing point that the design measures gear is less than effectively rising for tested gear
Beginning circular diameter.
A kind of teeth directional unsymmetric shape modification measures the application process of gear, includes the following steps：
1) detection measures the correction of the flank shape direction of gear, and is installed according to the direction and measure gear；
2) detection gear is coloured by red lead powder；
3) it measures gear and carries out double coloring cases nibbled detection, and observe red lead powder on tested gear with tested gear.
Compared with prior art, the beneficial effects of the invention are as follows：By carry out it is double nibble detection and can detect sideshake position lack
The defects of falling into, and then widths over teeth can be detected；Unqualified gear is avoided to flow into assembling, improves primary offline qualification rate.
Description of the drawings
Fig. 1 is the tested gear helical angle correction of the flank shape schematic diagram of the present invention.
Fig. 2 is the modification design figure of the measurement gear of the present invention.
Contact design sketch when Fig. 3 is not correction of the flank shape of the invention.
Fig. 4 is the contact design sketch after correction of the flank shape of the present invention.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the processing method that a kind of teeth directional unsymmetric shape modification measures gear includes the following steps：
1) by the number of teeth of tested gear, the facewidth, tip diameter, root diameter and measure gear installation center away from will
It asks, the number of teeth of corresponding design measurement gear, the facewidth, tip diameter, root diameter；
2) according to the axial modification requirement of tested gear, △ X=0.06mm, b=18mm are measured, and according to formula tan △ β
=△ X/b calculate 12 ' 8 〞 of helical angle correction of the flank shape angle △ β=0.0035 °=0 °, and wherein b is facewidth size；△ X are profiling quantity
Size；△ β are helical angle correction of the flank shape angle；
3) by the helical angle correction of the flank shape angle △ β in step 2) reversed roll flute is carried out to measuring gear.
A kind of teeth directional unsymmetric shape modification measures the application process of gear, includes the following steps：
1) detection measures the correction of the flank shape direction of gear, and is installed according to the direction and measure gear；
2) detection gear is coloured by red lead powder；
3) it measures gear and carries out double coloring cases nibbled detection, and observe red lead powder on tested gear with tested gear.
Fig. 3-4 are please referred to, are respectively the contact design sketch contacted after design sketch and correction of the flank shape of not correction of the flank shape, therefore can be obtained
The measurement gear gone out after correction of the flank shape can preferably detect sideshake regio defect, realize the defects of detecting widths over teeth, avoid and do not conform to
Lattice gear flows into assembling, improves primary offline qualification rate.
Alternatively, the profiling quantity size △ X >=0.02mm, pass through the survey to different axial modification sizes
It measures gear and carries out modification design and compliance test result, can be derived that smaller in correction of the flank shape, red lead powder dyeing inspection verification is repaiied
Contrast effect unobvious before and after shape, but effect is obvious in the case that correction of the flank shape is larger, general correction of the flank shape size within 0.02mm,
Gear is measured not need to carry out correction of the flank shape processing, but progress correction of the flank shape processing is just needed more than 0.02mm.
As optional technical solution, the meshing point of the design measurement gear is round directly less than effective starting of tested gear
Diameter.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
