Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
The embodiment of invention for those of ordinary skill in the art without creative efforts, can also basis
The attached drawing of offer obtains other attached drawings.
Fig. 1 is a kind of stream of the contact (area) pattern inspection adjustment process of method making bevel gear provided in an embodiment of the present invention
Journey schematic diagram.
Specific implementation mode
In order to make it easy to understand, the invention will be further described below in conjunction with the accompanying drawings.
Referring to Fig. 1, for a kind of contact (area) pattern inspection adjustment work for the method making bevel gear provided in an embodiment of the present invention
The flow diagram of sequence, " contact (area) pattern inspection adjust process " refer to check pairing bull wheel and steamboat in standard locating distance and
Whether the contact (area) pattern that rotate gear is formed in the case of rated service loads meets design requirement, does not meet such as, then to the flank of tooth
Finishing processing is carried out, until the contact (area) pattern under the above situation meets design requirement.
In the method provided in an embodiment of the present invention for making bevel gear, the contact (area) pattern inspection adjustment based on design requirement
Process includes step S1~S5：
The bull wheel of pairing and steamboat are assembled according to standard locating distance, colorant are smeared on working flank, specified by S1
Then rotate gear under the conditions of service load measures shape and the position of contact (area) pattern, is denoted as the first contact (area) pattern state.
It is " standard locating distance and rated service loads " this operating mode since the design requirement about contact (area) pattern is corresponding,
Therefore the contact (area) pattern under this kind of operating mode should be determined first.The design requirement of contact (area) pattern is usually with relative to wheel teeth size
Percentage provide, such as, it is desirable that the length of contact (area) pattern is not less than the 80% of tooth length, and big end and small end must not lift one's head,
The height of contact (area) pattern is not less than high 75% of tooth.
The shape of measurement contact (area) pattern and position, either taking a picture using camera, then measure phase by the way of
The contact (area) pattern region of on piece can also be to open up lower contact (area) pattern using adhesive tape, then measure the contact on adhesive tape
Speckle regions.
S2, judges whether the contact (area) pattern of the first contact (area) pattern state meets design requirement, if it is satisfied, then contact (area) pattern
It checks that adjustment process terminates, otherwise enters step S3.
S3 adjusts the locating distance of steamboat, colorant is smeared on working flank, turning gear under the conditions of rated service loads
Then wheel measures shape and the position of contact (area) pattern, is denoted as the second contact (area) pattern state, repeat step S3 until the second Bearing pattern
The contact (area) pattern of dotted state is consistent with the contact (area) pattern of design requirement.
In traditional production method, when the contact (area) pattern of the first contact (area) pattern state is unsatisfactory for design requirement, worker
The flank of tooth of steamboat can be machined in finishing and then secondary obtain the corresponding first contact (area) pattern state of the new flank of tooth according to step S1
(contact (area) pattern under " standard locating distance and rated service loads " operating mode), still, due to being difficult to estimate ratio to machined parameters
Appropriate correction amount not only causes production efficiency relatively low, also makes to make so the number for repeating processing steamboat can be relatively more
The cost that journey is spent is higher.
The present invention is different from traditional production method, in the method provided by the invention for making bevel gear, passes through first
The locating distance of steamboat is adjusted to make the contact of the second contact (area) pattern state (" non-standard locating distance and rated service loads " operating mode)
Spot is consistent with the contact (area) pattern of design requirement, then can be according to the final locating distance of steamboat relative to standard locating distance
Adjustment amount estimate the corresponding correction amount of machined parameters.
Relative to adjustment machined parameters, adjustment locating distance can relatively easily make contact of the contact (area) pattern with design requirement
Spot is consistent, therefore adjustment number is less, and worker then can be by the tune of locating distance when estimating the correction amount of machined parameters
Whole amount reduces the number of repetition processing with this, generally speaking, the present invention is relative to traditional making side as corresponding reference
Method can more expeditiously complete barrelling work.
S4 smears colorant on working flank, the rotate gear under idle condition, then measures the shape of contact (area) pattern
And position, it is denoted as third contact (area) pattern state.
The final adjustment amount of steamboat locating distance is with reference to after the correction amount for estimating machined parameters in step S3, it is clear that
The contact (area) pattern that should be formed to the flank of tooth processed again is checked, but if according to step as conventional fabrication method
S1 obtains the corresponding first contact (area) pattern state of the new flank of tooth, then can increase cost because of using additional loading equipemtn, institute
With the present invention is connect no longer using the first contact (area) pattern state as the state of checking of contact (area) pattern with the 4th in step S5
Check state of the spot state as contact (area) pattern is touched, the corresponding operating mode of the 4th contact (area) pattern state is " standard locating distance and sky
Carry ", without being loaded.
Since contact (area) pattern checks that state is become by traditional loading condition for the idle condition of the present invention, then to
Judge that the decision condition for checking whether state is qualified of contact (area) pattern should also be as making corresponding change, for this purpose, the present invention is first
The contact (area) pattern under " non-standard locating distance and zero load " operating mode is obtained by step S4, and (i.e. with the contact (area) pattern under this operating mode
" third contact (area) pattern state " in step S4) as new decision condition.
It should be noted that the installation that third contact (area) pattern state corresponding " non-standard locating distance " is final with steamboat in S3
Away from being identical numerical value, that is to say, that after step S3 terminates, keep locating distance constant, then carry out step S4.
S5 re-works the flank of tooth on the basis of flank of tooth of steamboat, and bull wheel and steamboat are assembled according to standard locating distance,
Colorant is smeared on working flank, then the rotate gear under idle condition measures shape and the position of contact (area) pattern, is denoted as the
Four contact (area) pattern states repeat step S5 until the 4th contact (area) pattern of contact (area) pattern state and connecing for third contact (area) pattern state
It is consistent to touch spot, contact (area) pattern inspection adjustment process terminates.

In it is defined be " zero load ", locating distance is same " non-standard locating distance ", and " the 4th contact (area) pattern state " with " first contacts
The difference of spot state " is " zero load " as defined in being also only that, locating distance is all " standard locating distance ", if " the 4th Bearing pattern
If the contact (area) pattern of dotted state " is consistent with the contact (area) pattern of " third contact (area) pattern state ", it is inferred that " first connects
Touch spot state " the contact (area) pattern of contact (area) pattern and " the second contact (area) pattern state " will also be consistent with, and due to " second
The contact (area) pattern of contact (area) pattern state " is consistent with the contact (area) pattern of " design requirement of contact (area) pattern ", it is possible to further
Infer that the contact (area) pattern of " the first contact (area) pattern state " meets design requirement.From above-mentioned deduction process it is found that " third contacts
Spot state " can check state " the 4th contact (area) pattern state " corresponding new decision condition as with new.
It, obviously should be first according to drawing by bull wheel and steamboat before contact (area) pattern inspection adjusts process when making bevel gear
It processes, in specific practical application, LTCA (load tooth contact analysis) can be based on and complete this partial content, therefore,
May include following gear teeth processing before contact (area) pattern inspection adjusts process in the method provided by the invention for making bevel gear
