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 for making bevel gear provided in an embodiment of the present invention
Journey schematic diagram.
Specific embodiment
In order to make it easy to understand, the invention will be further described with reference to the accompanying drawing.
Referring to Fig. 1, for a kind of contact (area) pattern inspection adjustment work for the method for 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 where 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 above situation meets design requirement.
In the method for production bevel gear provided in an embodiment of the present invention, 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 condition since the design requirement about contact (area) pattern is corresponding,
Therefore the contact (area) pattern under this kind of operating condition should be determined first.The design requirement of contact (area) pattern is usually relative to wheel teeth size
Percentage provide, such as, it is desirable that the length of contact (area) pattern is not less than long 80% of tooth, 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 for measuring 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 is also possible to open up lower contact (area) pattern using adhesive tape, then measures 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 and the contact (area) pattern of design requirement are consistent.
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 condition), still, due to being difficult to that machined parameters are estimated with ratio
Appropriate correction amount not only causes production efficiency lower, also makes to make so the number for repeating processing steamboat can be relatively more
The higher cost that journey is spent.
The present invention is different from traditional production method, in the method for production bevel gear provided by the invention, 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 condition)
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 production 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 referring 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 condition of the 4th contact (area) pattern state is " standard locating distance and sky
Carry ", without being loaded.
Since contact (area) pattern checks that state has become idle condition of the invention from traditional loading condition, then to
Judge whether He Ge decision condition should also be as making corresponding change for the state of checking of contact (area) pattern, for this purpose, the present invention is first
The contact (area) pattern under " non-standard locating distance and zero load " operating condition is obtained by step S4, and (i.e. with the contact (area) pattern under this operating condition
" third contact (area) pattern state " in step S4) as new decision condition.
It should be noted that the final installation of steamboat in third contact (area) pattern state corresponding " non-standard locating distance " and 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.

Spot is touched, i.e., " third contact (area) pattern state " mentioned above, operating condition as defined in " third contact (area) pattern state " meets " zero load "；
It is analyzed from the angle of operating condition, the difference of " third contact (area) pattern state " and " the second contact (area) pattern state " only exists
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
The contact (area) pattern of touching spot state " and the contact (area) pattern of " the second contact (area) pattern state " will be also 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 contact
Spot state ", which can be used as, checks state " the 4th contact (area) pattern state " corresponding new decision condition with new.
