る。 Generally, when assembling a wheel axle for a railway vehicle, the wheels are press-fitted onto the axle. However, in this press-fitting process, a certain amount of pressure is applied to force the wheel hole of the wheel, which is also small in diameter, into the wheel hole of the axle seat, which causes friction spots called galling on the axle seat. There are often things to do. Also,
The above-mentioned friction flaws may also occur when a gear for driving the rotation of the wheel is press-fitted into the inner side of the wheel. Furthermore, when inspecting axles or replacing wheels, friction flaws frequently occur due to pressure being removed or press-fitted. Also, when friction flaws were severe, the axle was scrapped. For this reason, the wheels are press-fitted to prevent friction scratches from forming on the axle seats. It is necessary to relieve the pressure.

ある。 On the other hand, when fitting two objects together, if the two objects are fitted linearly with a constant pressing force and a direct force, considerable frictional resistance will occur and it will not be possible to fit them together easily. It is well known that when one or both of the two objects are fitted while being rotated, this rotational movement allows for extremely smooth fitting even with the same pressing force as described above.

である。 Therefore, in order to smoothly press fit a wheel onto an axle and release pressure from the axle, the present invention presses in and removes pressure while rotating the wheel. A method for preventing friction scratches, in which the wheel is rotated by using a rotating device that has a rotating roller that comes into contact with a part of the outer circumferential surface of the wheel and that moves along with the wheel in the axial direction. Characterized by... press-fitting of the wheel onto the axle. This provides a pressure relief method.

Touch the end. In this state, when the press 6 is operated to advance the press head 7, the wheel 3 is pressed and press-fitted into the seat 2 of the axle 1. At this time, the wheel 3 is press-fitted while being gently rotated by a rotating device 12 having a rotating roller 11 brought into contact with a part of the outer peripheral surface of the wheel 3 in advance. In this case, the rotating device 12 is moved together with the wheels 3. Due to the rotational movement of the wheel, even with the same pressing force, it can be press-fitted very smoothly.

寿命延長がはかられる効果を奏する。 Next, when depressurizing the wheel 3 from the seat 2 of the axle 1, place the axle end on the side opposite to the wheel depressing side on the axle bearing truck 21, fix it with the fixing screw 22, and press The axle pushing jig 10' attached to the press head 7 of 6 is brought into contact with the axle end on the wheel pressure relief side, and the wheel pushing jig 8' attached to the resistor head 9 is brought into contact with the outer surface of the wheel 3. Let them come into contact with you. When the press 6 is operated in this state and the press head 7 is paid out, the axle 1 is pressed and moved, whereby the wheel 3 is released from the seat 2 of the axle 1. At this time, the pressure is released while the wheel 3 is slowly rotated by the rotating device 12, as in the case of the press-fitting described above. In this case, since the wheels 3 do not move, the connecting member 15 is removed and the rotating device 12 is fixed in place. Due to the rotational movement of the wheels, even with the same pressing force, the pressure is released very smoothly. As described above, this invention is a method for press-fitting a wheel onto an axle and releasing pressure from the axle while gently rotating the wheel. It can be press-fitted or press-released very smoothly, and no friction scratches will occur on the axle seat during press-fitting or press-release. Therefore,
This eliminates the need for repair work for friction scratches, and has the effect of extending the life of the axle.

ことができる。 In addition, as a method for rotating the wheel during press-fitting and press-release, a rotating device is used in which a rotating roller that contacts the outer peripheral surface of the wheel is moved in the axial direction together with the wheel, which is structurally simple and easy to use compared to existing press-fitting and press-release. It has the effect of being easily attached to a pressure relief device,
In addition, since it can be synchronized with the drawing-out operation of the press head, it has the effect of being able to cope with differences in the press-in stroke of the wheels, and the assembly or disassembly of the wheel axle for a railway vehicle can be carried out smoothly and efficiently.
