Background technology：
Gear shaft has a wide range of applications in machinery field, in order to play the role of fixed conveyor, needs to add on gear shaft
Work keyway gives gear shaft passing power, the accuracy of keyway processing straight when use by installing various types of keys on keyway
Connecing influences the service life of power transmission and gear shaft, and keyway Working position inaccuracy will lead to gear shaft fluctuation of service, grinds
Damage is serious, reduces the service life of gear shaft, therefore have strict requirements for the Working position of keyway, as shown in Figure 1, it is desirable that add
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 axis or tooth socket line of symmetry.
Currently, determining 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 that gear shaft level to be processed is erected at boring machine or milling machine first
Workbench on, the straight shaft portions at gear shaft both ends pull up table centering, then recycle lever measurement table 1 and lever measurement table 2
The tooth for measuring two gear teeth symmetrical about gear shaft and level of approximation respectively is high, repeatedly turning gear wheel shaft, until two gear teeth
Highly consistent, the axis center of centering gear shaft, keyway is then processed on gear shaft, there are following for this keyway processing method
It is insufficient：The first, it is only suitable for processing the gear shaft of the even number of teeth, is not suitable for processing odd-toothed gear shaft；The second, measurement 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 tooth form standard figures of gear shaft to be processed
It cuts and is processed into model, when the gear shaft number of teeth is even number, benchmark Alveolus type model is made, 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 reference plane A and B is parallel to benchmark tooth socket
Center line or datum tooth center line, reference plane C and D are processed perpendicular to benchmark tooth space centerline or datum tooth center line with model
The installation of method, gear shaft is identical as gear teeth symmetry measurement, is only needed in a pre-installation the model made by the form of gear tooth
It is sleeved on gear shaft, with the arbitrary measurement datum on dial gauge centering gear model, the above method before keyway processing
It has the following disadvantages：First, each 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 when making is processed according to the standard size of gear, and work gear to be added
There are mismachining tolerances with master gear for axis, therefore the size of model and the gear size on gear shaft to be processed is caused to be to have
Error, cause model tooth form with the tooth form on gear shaft there are fit clearance, the Working position for eventually leading to keyway misses
Difference.
