A non-oiling press mounting process between a wheel and an axle of a locomotive comprises the steps as follows: a sharp steel blade is chosen for processing an inner hole of the wheel, the cutting depth is 0.2mm-0.25mm, the feed amount is 1.37mm, the revolution is 63r/min, the roughness of the machining face is Ra4-6.3, the shrink range of the inner hole and a wheel seat on the axle is 0.24mm-0.28mm, the processed axle is positioned on a press, the assembling surface is cleaned, the lubricating grease is applied, and then the wheel is hung at the wheel seat through sliding a guide sleeve, the press mounting working tyre position is adjusted to lead the axle to be coincided with the center line of an oil press, the axle is aligned with a piston rod of the oil press for press mounting, the press mounting speed is 70mm-80mm per minute, the press mounting tonnage is 110t-120t, the wheel press mounting position is controlled, and the pressure curve and the pressure value are recorded. The process has the advantages of simple operation, low cost, reliable quality and unnecessary back pressure test.
Description
Technical field
The present invention relates to a kind of locomotive wheel and axletree and do not have the oil-filling type press-loading process.
Background technology
The assembly technology of locomotive wheel and axletree; The employing oiling press-fit approach that has at present; Need be processed with the hydraulic oil annular groove at the endoporus place of wheel before press-fiting, get into axletree and the high-voltage oil cavity of a ring-type of hydraulic oil annular groove formation in the wheel hole when press-fiting, this oil pocket and hydraulic oil are from being connected to device; Hydraulic oil plays lubrication when axletree gets into the wheel hole, also the wheel endoporus is played dilating effect simultaneously.This press-loading device is complicated, troublesome poeration, and cost is high, and assembly quality is unstable.
Summary of the invention
The locomotive wheel and the axletree that the purpose of this invention is to provide a kind of easy and simple to handle, with low cost, reliable in quality, need not to do the back-pressure test do not have the oil-filling type press-loading process, overcome the deficiency of prior art.
Locomotive wheel of the present invention and axletree do not have the oil-filling type press-loading process, comprise the steps:
A, by the endoporus 6 of design size processing wheel 5, process tool is selected the high-speed steel cutter, bite is controlled between the 0.2mm-0.25mm, the amount of feeding is 1.37mm, the lathe rotating speed is 63r/min, the inner bore surface roughness after the processing is Ra4～6.3;
B, confirm the magnitude of interference between the wheel seat 2 on endoporus 6 and the axletree 1, the said magnitude of interference is controlled between the 0.24mm-0.28mm;
C, that will process and axletree 1 that satisfy the above-mentioned magnitude of interference place on the work that the press-fits position of foetus of forcing press and the location clamps; Wipe clean being used on the axletree 1 and overlap the outer surface of the wheel seat 2 of wheel-mounted 5, evenly smear the press mounting of car wheel to the outer surface of wheel seat 2 and use lubricating grease, be enclosed within wheel seat side axle journal 3 places after the press mounting of car wheel is wiped clean with fairlead 4;
D, wheel 5 is sling; With leveling instrument finishing wheel endoporus porch burr tool marks; Make it rounding off; Clean endoporus 6 with clean no mao mao's towel then, smear the press mounting of car wheel vertically uniformly at endoporus 6 places of wheel 5 and use lubricating grease, then wheel 5 is slipped over fairlead 4 and hang onto the wheel seat place;
E, adjustment press-fit the work position of foetus, make the axis of axletree 1 consistent with the forcing press center line, and the end of axletree 1 is aligned the rampiston bar, and the opening pressure machine press-fits then, and press-fiting speed is per minute 70mm-80mm, and mounting tonnage is 110 tons-120 tons;
F, control press mounting of car wheel position well, write down the pressure curve and the pressure value that press-fit in the process, accomplish the press mounting of car wheel.
Locomotive wheel of the present invention and axletree do not have the oil-filling type press-loading process compared with prior art, have easy and simple to handle, with low cost, reliable in quality, need not do the advantage of back-pressure test.
Description of drawings
Fig. 1 is the sketch map that press-fits between axletree of the present invention and the wheel.
The specific embodiment
As shown in Figure 1: concrete processing step is following:
A, by the endoporus 6 of design size processing wheel 5, process tool is selected the high-speed steel cutter, bite is controlled between the 0.2mm-0.25mm, the amount of feeding is 1.37mm, the lathe rotating speed is 63r/min, the inner bore surface roughness after the processing is Ra4～6.3;
B, confirm the magnitude of interference between the wheel seat 2 on endoporus 6 and the axletree 1, the said magnitude of interference is controlled between the 0.24mm-0.28mm;
C, that will process and axletree 1 that satisfy the above-mentioned magnitude of interference place on the work that the press-fits position of foetus of forcing press and the location clamps; Wipe clean being used on the axletree 1 and overlap the outer surface of the wheel seat 2 of wheel-mounted 5, evenly smear the press mounting of car wheel to the outer surface of wheel seat 2 and use lubricating grease, be enclosed within wheel seat side axle journal 3 places after the press mounting of car wheel is wiped clean with fairlead 4;
D, wheel 5 is sling; With leveling instrument finishing wheel endoporus porch burr tool marks; Make it rounding off; Clean endoporus 6 with clean no mao mao's towel then, smear the press mounting of car wheel vertically uniformly at endoporus 6 places of wheel 5 and use lubricating grease, then wheel 5 is slipped over fairlead 4 and hang onto the wheel seat place;
E, adjustment press-fit the work position of foetus, make the axis of axletree 1 consistent with the forcing press center line, and the end of axletree 1 is aligned the rampiston bar, and the opening pressure machine press-fits then, and press-fiting speed is per minute 70mm-80mm, and mounting tonnage is 110 tons-120 tons;
