Description
Technical field：
The present invention relates to keyway processing technique field, and in particular to a kind of gear shaft key groove Working position determines method.
Background technology：
Gear shaft has a wide range of applications in mechanical field, in order to play a part of fixed conveyor, needs to add on gear shaft
Work keyway, power is transmitted when using by installing various types of keys on keyway to gear shaft, and the accuracy of keyway processing is straight
Connecing affects the service life of power transmission and gear shaft, and keyway Working position is inaccurate will to cause gear shaft to run not quietly, mill
Damage serious, reduce the life-span of gear shaft, therefore for the Working position of keyway has strict requirements, as shown in Figure 1, it is desirable to plus
Keyway line of symmetry after work intersects with the center of circle of shaft section, and keyway line of symmetry is conllinear with the gear teeth on axle or teeth groove line of symmetry.
At present, determine that Working position method of the keyway on gear shaft mainly has gear teeth symmetry measurement and gear model to add
Engineering method, as shown in Fig. 2 gear symmetry measurement cardinal principle is first gear shaft level to be processed to be erected at into boring machine or milling machine
Workbench on, the straight shaft portions at gear shaft two ends pull up table centering, then recycle lever measurement table 1 and lever measurement table 2
The tooth for measuring and two gear teeth of level of approximation symmetrical with regard to gear shaft respectively is high, repeatedly turning gear wheel shaft, until two gear teeth
Highly consistent, the axle center of centering gear shaft, then process keyway on gear shaft, this keyway processing method exists following
It is not enough：Firstth, it is only suitable for processing the gear shaft of the even number of teeth, is not suitable for processing odd-toothed gear shaft；Secondth, measure error
Larger, the Working position accuracy of keyway is not high, and qualification rate is relatively low.
As shown in figure 3, gear model processing method cardinal principle is cut with line by the profile of tooth standard figures of gear shaft to be processed
Cut and be processed into model, when the gear shaft number of teeth is even number, make benchmark Alveolus type model, when the gear shaft number of teeth is odd number,
Datum tooth style plate is made, the surrounding of model is measurement datum A, B, C, D, and wherein datum level A and B is parallel to benchmark teeth groove
Center line or datum tooth center line, datum level C and D is processed perpendicular to benchmark tooth space centerline or datum tooth center line with model
Method, the installation of gear shaft is identical with gear teeth symmetry measurement, simply needs in a pre-installation the model made by the form of gear tooth
It is sleeved on gear shaft, with any measurement datum on dial gauge centering gear model, said method before keyway processing
Have the following disadvantages：First, every kind of gear shaft needs the model of on-demand customization different size because of module, number of teeth difference,
Poor universality, high processing costs；Secondly, model is processed according to the standard size of gear when making, and work gear to be added
There is mismachining tolerance in axle, therefore cause the size of model and the gear size on gear shaft to be processed to be have with master gear
Error, cause model profile of tooth to there is fit clearance with the profile of tooth on gear shaft, missing occurs in the Working position for ultimately resulting in keyway
Difference.
