Abstract
The utility model provides an internal spline rotating shaft of a motor. The internal spline rotating shaft is an internal spline shaft sleeve arranged in a spindle hole of the motor; the spindle hole and a peripheral surface between the internal spline shaft sleeves form tight coordination; a plurality of locating holes are formed in the peripheral surface of the motor; the positions of the locating holes correspond to the positions of the internal spline shaft sleeves, and fixing pins for fixing the internal spline shaft sleeves are arranged in the locating holes. The internal spline rotating shaft of the motor provided by the utility model has a simple structure, easiness for processing, relatively higher quality and reliability of processed product.
Description
Technical field
The utility model relates to the Machining Technology field, the rotating shaft of particularly a kind of motor internal spline.
Background technique
The mechanical connection manner of motor driving oil pump mainly contains two kinds at present: first kind of mode is through coupling the shaft of motor and the shaft of oil pump to be coupled together; The second way is that the shaft of motor is made the internal spline structure, and the shaft of oil pump directly inserts in the motor internal spline quill shaft and couples together.Structurally, the second way has been saved intermediate shaft coupling, has advantages such as compact structure and minimizing vibration, thereby becomes preferred Placement.
Therefore in implementing for above-mentioned second kind of Placement, the internal spline that how to process rotating shaft becomes critical process.In the prior art; The whole processing mode processing of main employing rotor that is to say, directly processes the spline perforation in the preceding shaft extension end of rotor usually; This method processing is required great effort, efficient rotor yield rate low, that process is low, q&r also is difficult to guarantee but be to use; And in case produce substandard products, waste product and just can only scrap whole rotating shaft, raised cost of production, can not carry out flexible configuration according to client's different needs.
The model utility content
To the problems referred to above, the purpose of the utility model provides the rotating shaft of a kind of motor internal spline, this motor internal spline rotating shaft simple in structure, be easy to processing, and the q&r that processes is all higher relatively.
For achieving the above object, the utility model adopts following technological scheme:
The rotating shaft of a kind of motor internal spline; Said internal spline rotating shaft is the internal splined shaft bushing that is arranged in the electric machine main shaft hole; Form between the outer peripheral surface of said spindle hole and said internal splined shaft bushing and closely cooperate; Have a plurality of positioning holes on the outer peripheral surface of said motor, the position of said positioning hole is corresponding with the position of said internal splined shaft bushing, is provided with the fixing pin that is used for fixing said internal splined shaft bushing in the said positioning hole.
Further, the inner peripheral surface of said internal splined shaft bushing is provided with regularly arranged spline tooth, and said spline tooth is suitable with the oil pump shaft that inserts said internal splined shaft bushing.
Further, said internal splined shaft bushing is a cylindrical structural.
Further, the quantity of said positioning hole is even number.
Further, the quantity of said positioning hole is 2.
The p-m rotor of the utility model is owing to adopt above technological scheme; It has the following advantages: the motor internal spline rotating shaft that the utility model provides is the internal splined shaft bushing that is arranged in the electric machine main shaft hole; It is simple in structure, be easy to processing, and the q&r that processes is all higher relatively.Its during fabrication, at first shaft extension end bore hole before rotor utilizes hot pressing mode that internal splined shaft bushing is pressed in the electric machine main shaft hole then, it is fixing to use fixing pin that internal splined shaft bushing is strengthened after cooling.The method that the utility model proposes has overcome the technological deficiency that whole processing mode brought in the existing technology.
Description of drawings
Fig. 1 is the structural representation of the motor internal spline rotating shaft of the utility model proposition.
Embodiment
For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1; The utility model provides the rotating shaft of a kind of motor internal spline; Said internal spline rotating shaft is the internal splined shaft bushing 2 that is arranged in the electric machine main shaft hole 1, forms between the outer peripheral surface of said spindle hole 1 and said internal splined shaft bushing 2 to closely cooperate, and has a plurality of positioning holes 3 on the outer peripheral surface of said motor; The position of said positioning hole 3 is corresponding with the position of said internal splined shaft bushing 2, is provided with the fixing pin 4 that is used for fixing said internal splined shaft bushing 2 in the said positioning hole 3.
In a preferred embodiment of the utility model; The inner peripheral surface of said internal splined shaft bushing 2 is provided with regularly arranged spline tooth 5; Said spline tooth 5 is suitable with the oil pump shaft that inserts said internal splined shaft bushing 2; Be that the oil pump shaft will closely cooperate with spline tooth 5 formation of internal splined shaft bushing 2, to guarantee the proper functioning of motor.In the present embodiment; The shape of internal splined shaft bushing 2 is preferably cylindrical structural; Naturally, those skilled in the art were familiar with has the protection domain that other shapes and internal splined shaft bushing that can realize the utility model identity function also should be included the utility model in, is not giving unnecessary details here.
In a preferred embodiment of the utility model; For internal splined shaft bushing 2 is fixing effectively, make it in rotation process, keep stable, the sidesway along major axes orientation does not take place, the quantity of the positioning hole 3 of the utility model is even number; As a kind of optimal way; Quantity that can positioning hole 3 is set to 2, can certainly be according to the needs of actual operating state, and the quantity of positioning hole 3 is set to 4,6 or 8 etc.
In the utility model, the mode that can adopt hot pressing is pressed into shaft extension before the rotor with internal splined shaft bushing 2, and concrete steps are:
Shaft extension before step 2, the heating rotor is pressed into the preceding shaft extension of rotor with pre-processed internal splined shaft bushing 2 then;
In actual production, can bore the spindle hole of different-diameter according to size shaft extension before rotor of the internal splined shaft bushing of reality, and then utilize hot-pressing method to be pressed in the spindle hole corresponding internal splined shaft bushing with it according to the actual design needs.The utility model adopts first bore hole, after be pressed into internal splined shaft bushing, with the fixing mode of internal splined shaft bushing of fixing pin, reduced cost of production at last, and simple in structurely be easy to assembling.And the whole processing rotor mode of main employing in the existing technology; The shaft extension end directly processes spline tooth before rotor; But the yield rate of using this method to obtain is lower, and q&r also is difficult to guarantee, and in case produce substandard products, waste product and just can only scrap whole rotating shaft; Raised cost of production, can not carry out flexible configuration according to client's different needs.
The preferred embodiment that the above is merely the utility model is not the practical range that is used for limiting the utility model; If do not break away from the spirit and the scope of the utility model, the utility model is made amendment or is equal to replacement, all should be encompassed in the middle of the protection domain of the utility model claim.
