Abstract
The invention provides a processing method of a taper shaft of a driving device. During a shaft grinding process, a distance between a shaft shoulder and an end face inside a ring gauge is measured to adjust the taper, major diameter and length of the taper shaft synthetically and accurately and to control dimensional tolerance to be within an allowed range accurately, so that the connecting coaxiality and structural tightness of a spindle and a coupling of the driving device can be improved. The processing method includes taking the shaft shoulder of the spindle as a datum reference, processing a section of cylindrical shaft body with a diameter of D and a length of Z+/-c first; after the processing of the cylindrical shaft body, starting processing the side end relative to the shaft shoulder of the shaft body by a grinding machine; taking the grinding end of the shaft body as a datum reference, covering the ring gauge outside; and measuring the distance between the shaft shoulder and the end face inside the ring gauge through the ring gauge when the shaft is ground, and stopping grinding the shaft until the length of Y+/-b is reached so as to process the taper shaft with the taper of 1:X, the diameter of d+/-a and the length L.
Description
Technical field
The present invention relates to a kind of axis of cone processing method that is applied to the rail vehicle drive unit, grind axle processing to gearbox shaft that is connected in the shaft coupling two ends and traction electric machine axle particularly, belong to mechanical manufacturing field.
Background technology
At present the domestic rail vehicle speed per hour that runs on main line railway reached 380 kilometers and more than, thereby more strict design and serviceability requirement have been proposed for dynamical system.
In the rail vehicle drive system, traction electric machine and gear-box all are installed on the bogie frame below.The pinion shaft of the driving shaft of traction electric machine through shaft coupling connection gear case, the Large Gear Shaft During of gear-box then directly be sheathed on two side wheels between vehicle on.Under normal circumstances, for guarantee traction electric machine with take turns between the tractive force transmission require traction electric machine axle and pinion shaft flatly to be connected in the shaft coupling both sides.
In the prior art, the rotating shaft link of above-mentioned drive unit is to be processed into the axis of cone structure that has certain taper through grinding machine.Process and detection method owing to lack high-precision mill axle, the margin of tolerance of axis of cone processing dimension is bigger, thus have influence on shaft coupling be connected axiality and tightness degree, particularly the machining accuracy of axis of cone Surface Taper awaits further raising.
In view of this, the special present patent application that proposes.
Summary of the invention
Drive unit axis of cone processing method of the present invention; Its purpose is to solve problem that above-mentioned prior art exists and in the process of mill axle; Distance through measuring the shaft shoulder and ring gauge inner side end is with synthetically, accurately regulate the tapering of the axis of cone, greatly directly size and length; And accurately the controlling dimension tolerance within the technology allowed band, thereby improve drive unit rotating shaft and shaft coupling be connected axiality and imporosity.
Be to realize the foregoing invention purpose, described drive unit axis of cone processing method is that the shaft shoulder with rotating shaft is a positioning reference, and at first processing one section diameter is that D, length are the cylindric axis body of Z ± c.
The difference with the prior art part is, after the processing of accomplishing above-mentioned cylindric axis body, re-uses grinding machine and begins to process from the side of axis body with respect to the shaft shoulder;
Abrasive tip with axis body is a positioning reference, overcoat one ring gauge;
In the mill axle, use ring gauge to measure the distance of the shaft shoulder with respect to the ring gauge inner side end, promptly stop the mill axle until the length that reaches Y ± b, be 1 to process tapering: X, big footpath are of a size of d ± a, length is the axis of cone of L.
Wherein, D＞(d ± a), a is the tolerance of the diameter of the bigger end of axis of cone size, and b is the tolerance of length of the axis body remainder of the undressed one-tenth axis of cone, and c is the tolerance of axis body total length.
The axis of cone of the present invention is meant that the traction electric machine axle that is connected the shaft coupling two ends, the pinion shaft of gear-box are processed to have the part axis body of certain surface tapering.
For further improving the accuracy of control axis of cone partial-length, the value of tolerance b is the product of radial tolerance a and tapering X, i.e. b=a * X.
For optimizing and the tapering that improves axis of cone surface, can the tolerance of conical surface length L be set at ± b ± c, promptly the margin of tolerance (b-c) and (+b+c) between.
For detecting the degree of accuracy of axis of cone processing in real time, can be through detecting the contact area of ring gauge and axis of cone outer surface, to detect the degree of accuracy of axis of cone processing.
Content to sum up; The advantage that said drive unit axis of cone processing method has is; Can carry out the detection of tapering processing in real time; Mutual precision control between synthetically balanced a plurality of parameters realizes the controlling dimension tolerance within the technology allowed band, is connected axiality and imporosity with the rotating shaft of final raising drive unit and shaft coupling.
Description of drawings
The following accompanying drawing of existing combination is done explanation further to the present invention
Fig. 1 is the sketch map of said drive unit axis of cone processing;
As shown in Figure 1, rotating shaft 1, the shaft shoulder 2, axis body 3, ring gauge 4.
The specific embodiment
At first, be positioning reference with the shaft shoulder 2 of rotating shaft 1, processing one section diameter is that D, length are the cylindric axis body 3 of Z ± c;
Secondly, use grinding machine to begin to process from the side of axis body 3 with respect to the shaft shoulder 2;
Simultaneously, be positioning reference with the abrasive tip of axis body 3, overcoat one ring gauge 4;
In the mill axle, use ring gauge 4 to measure the distance of the shaft shoulder 2 with respect to ring gauge 4 inner side ends, promptly stop the mill axle until the length that reaches Y ± b;
It is 1 that the axis of cone that processes as stated above, its dimensional parameters are respectively tapering: X, big footpath are of a size of d ± a, length is the axis of cone of L.
Wherein, D＞(d ± a),
The value of tolerance b is the product of radial tolerance a and tapering X,
The tolerance of conical surface length L is ± b ± c.
After the processing technology of accomplishing the said axis of cone, through detecting the contact area of ring gauge and axis of cone outer surface, to detect the degree of accuracy of axis of cone processing.
