Refer to Fig. 1 to Fig. 3.It should be noted that, the diagram provided in the present embodiment only illustrates basic conception of the present invention in a schematic way, then only the assembly relevant with the present invention is shown in graphic but not component count, shape and size when implementing according to reality is drawn, it is actual when implementing, and the kenel of each assembly, quantity and ratio can be a kind of change arbitrarily, and its assembly layout kenel also may be more complicated.
The initial residual amount of unbalance target setting method of transmission shaft provided by the invention, comprises the following steps:
S101, one group of transmission shaft is carried out to the dynamic balance calibration of initial phase.After dynamic balance calibration, transmission shaft becomes correction transmission shaft.This group transmission shaft is same specification, and with this group transmission shaft as sampling sample, the number of transmission shaft is more than or equal to 50, and namely sample number is more than or equal to 50.
S102, carrying out the dynamic balancing measurement of initial phase with dynamic-balance measuring system to correcting transmission shaft, obtaining initial phase residual unbalance.
S103, the clamping workpiece of dynamic-balance measuring system is turned over turnback, make transmission shaft be positioned at upset phase place, again dynamic balancing measurement is carried out to correction transmission shaft, obtains the upset phase place residual unbalance, correcting transmission shaft.
For step S101 to S103, dynamically balanced dynamic balancing machine, the dynamic-balance measuring system carrying out dynamic balancing measurement, dynamic balance method and balancing measuring method are carried out to this group transmission shaft and all remains unchanged.
S104, according to the initial phase residual unbalance, obtained in above-mentioned steps and upset phase place residual unbalance, vector method is utilized to calculate the system amount of unbalance of dynamic-balance measuring system.
Above-mentioned initial phase residual unbalance, upset phase place residual unbalance, and system amount of unbalance are vector.
The calculating formula utilizing vector method to calculate the system amount of unbalance of dynamic-balance measuring system is:
System amount of unbalance=1/2 (initial phase residual unbalance,+upset phase place residual unbalance).The vector meter nomogram corresponding to calculating formula refers to Fig. 2.
S105, according to the initial phase residual unbalance, obtained in above-mentioned steps, upset phase place residual unbalance, and system amount of unbalance, continue to utilize vector method to calculate and correct transmission shaft correspond to the true residual unbalance, of initial phase of initial phase and correspond to the true residual unbalance, of upset phase place that 180 degree overturn phase places.The true residual unbalance, of initial phase and the true residual unbalance, of upset phase place are also vector.
The calculating formula utilizing vector method to calculate the true residual unbalance, of initial phase is:
The true residual unbalance, of initial phase=initial phase residual unbalance,-system amount of unbalance.
The calculating formula utilizing vector method to calculate the true residual unbalance, of upset phase place is:

The vector meter nomogram corresponding to the calculating formula of these two true residual unbalance,s refers to Fig. 3.
S106, according in design specifications to the requirement residual unbalance, of transmission shaft, set one group of initial phase and allow residual unbalance.The initial phase of setting allows the requirement residual unbalance, that requires in residual unbalance, and design specifications should in same accuracy class, and is less than this and requires residual unbalance.
Each initial phase according to setting allows residual unbalance, utilize the true residual unbalance, of all initial phases and the true residual unbalance, of upset phase place that obtain in abovementioned steps, calculated the Measure of Process Capability obtaining and allows residual unbalance, corresponding with each initial phase by process capability, by the Measure of Process Capability of calculating gained closest to 1.67 time corresponding initial phase permission residual unbalance, be set as initial residual amount of unbalance index.

In the present invention by CPK value closest to 1.67 time corresponding initial phase allow residual unbalance, to be set as initial residual amount of unbalance index, also illustrate that the quality assurance of transmission shaft is at top grade under this initial residual amount of unbalance index.
The unit of amount of unbalance is gmm.Such as certain transmission shaft, it requires that residual unbalance, is 85gmm, according to experimental formula of the prior art, should arrange initial residual amount of unbalance index is 56gmm, and calculate the known quality of transmission shaft under high-precision requirement that will ensure by process capability of the present invention, needing initial residual amount of unbalance setup measures is that 40gmm just can meet the demands.Above-mentioned numerical value is the modulus of vector value.
In sum, transmission shaft initial residual amount of unbalance target setting method provided by the invention, no longer rely on experimental formula, but vector method is combined with process capability computing method, there is the theoretical foundation of science, can the transmission shaft of accurate analysis high-precision requirement, the initial residual amount of unbalance index of transmission shaft is more accurately and reliably set; Due to consider in survey calculation process simultaneously transmission shaft initial phase and 180 degree upset phase places amount of unbalance, therefore obtain on the basis of reliable authentication at process capability, effectively can reduce the frequency of transmission shaft upset repetition measurement, improve Product Precision and production efficiency simultaneously.
