Step S3：The gear teeth on bull wheel and steamboat are divided into p groups and q groups respectively, are joined according to the processing determined in step S2
Number is processed so that machined parameters different from according to different gear teeth groupings.A pair of of gear exemplar is finally obtained, they
The gear teeth there is same macroscopical geometry and different microscopic appearances by group differentiation；
Step S4：A pair of of the gear machined in step S3 is subjected to adjustment, gear fatigue is carried out on test-bed
Engagement experiment.It is shut down every one section of set time and observation of taking pictures is carried out to whole flank of tooth, to find flank engagement failure in time simultaneously
Record failure evolution；The gear teeth number of record failure, the gear teeth grouping where it and out-of-service time.Until each group occurs
Fail the gear teeth, stops experiment；
Step S5：Tooth failure data are analyzed, calculate the mean value in each group gear teeth service life, it can be determined that each group machined parameters group
The influence direction to gear engagement fatigue life and size are closed, and filters out and engages fatigue life optimal several groups to extending gear
Machined parameters combine.
Further, in above-mentioned steps S3, every group of gear teeth number is no less than 2 teeth when being grouped to the gear teeth, to protect
Confirmatory test data acquire enough information content.
Further, during the experiment of above-mentioned steps S4, can the big steamboat of subsidiary nearby vibration signal, monitor gear
Tired state of development in engagement.
Beneficial effects of the present invention：
(1) the present invention provides a kind of method, and multigroup machined parameters are applied in multigroup gear teeth processing of same gear,
And fatigue engagement experiment is carried out to single pair gear, for investigating influence of the different machining parameters to gear engagement fatigue behaviour.With
Conventional gears engagement experiment process is compared, and method provided by the invention can greatly reduce the quantity of tests exemplar, and can be significantly
Shorten the test period, reduce financial cost and time cost.
(2) method provided by the invention causes a pair of of gear of a needs during processing and testing.For each on gear
For the gear teeth of the group using different machining parameters processing, trueness error caused by adjustment is consistent during processing and experiment, avoids
The error that respectively adjustment introduces during multipair Gear Processing and experiment is conducive to improve test accuracy.
Description of the drawings
Fig. 1 is the test method flow chart of the present invention；
Fig. 2 is grinding test parameter grouping Processing scheme.
Specific embodiment
It elaborates below in conjunction with the accompanying drawings to the embodiment of the method for the present invention.Although the disclosure is shown in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here institute
Limitation.It is to be able to be best understood from the disclosure, and can be complete by the scope of the present disclosure on the contrary, providing embodiment
It is communicated to those skilled in the art.It should be noted that in the absence of conflict, embodiment and embodiment in the present invention
In feature can be combined with each other.The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The embodiment of the present invention investigates different technological parameter groups using the grinding process parameters of a pair of of spiral bevel gear as object
Close the influence that fatigue life is engaged to it.The grinding process parameters of investigation include grinding linear velocity, transform into two factors of speed.It is real
Example is applied to include the following steps：
Step (1)：Design gear basic parameter, such as table 1.
1 embodiment gear parameter of table
Step (2)：In view of the number of teeth of bull wheel and steamboat, steamboat is ground linear velocity, speed is transformed into and is set to two water respectively
It is flat, such as table 2；By the grinding linear velocity of bull wheel, transform into speed be set to respectively three level, such as table 3.The steamboat then to be investigated processing ginseng
Array conjunction has 4 groups, and the combination of bull wheel machined parameters has 9 groups.
2 steamboat cutting parameter testing program of table
3 bull wheel cutting parameter of table is grouped scheme
Step (3)：The gear teeth on steamboat and bull wheel are divided into 4 groups and 9 groups, and respectively according to gear teeth group number in table 2 and table 3
The grinding process parameters combination of distribution, is processed on a pair of of gear blank, such as Fig. 2.
Step (4)：It will process in obtained a pair of of gear normal mounting to engagement testing stand and carry out fatigue test.Every 2 is small
When shut down the observation flank of tooth and tooth root situation and photograph to record, while gear revolution when recording shutdown.
Step (5)：Due in this example steamboat failure occur earlier, to steamboat flank engagement failure logging (record) data into
It goes and handles, calculate the average burn-out life of each group gear teeth, difference is ground linear velocities, transforms into velocity composition pair during contrast process
Steamboat engages the influence of fatigue failure life, such as table 4.
Each tooth burn-out life statistical data of 4 steamboat of table
By statistical result it can be seen that：For each group gear teeth being processed using the combination of different grinding parameters, service life
It is descending to be arranged as L1>L4>L2>L3.It can be found that transform into smaller two groups of gear teeth (the L1 and L4) longest-lived of speed；Grinding
One group of (L3) service life that linear velocity is relatively low, to transform into speed larger is minimum.Conclusion obtains higher grinding linear velocity, relatively low transforms into
Speed can play gear teeth meshing fatigue behaviour facilitation, the conclusion that the 1st group of machined parameters is selected to be processed as far as possible.
To sum up, by more than flow, multigroup machined parameters combination can be realized in the engagement fatigue test of a pair of of gear
The assessment influenced on gear engagement fatigue life.The present invention is investigates gear multi-processing technological parameter to gear teeth meshing fatigue life
Influence provide it is a kind of quick, save, high-precision test method.
Non-elaborated part of the present invention belongs to techniques well known.All shapes using equivalent transformation or equivalent replacement
Into technical solution, all fall within rights protection scope of the present invention.
