Definitions
- the present invention relates to an apparatus for attaching and detaching a member to an axle or the like.
- a member fitted to a shaft of a track vehicle or the like such as an oil retaining collar fitted to a shaft of a motor for a driving wheel, is removed from the shaft for periodic inspection and the like.
- an AC current is applied to a coil disposed on the outer periphery of the member to be fitted, an AC magnetic field is applied to the member, and the member is heated and expanded by induction, thereby reducing hydraulic pressure and the like.
- a device and method for extracting with a motive extraction mechanism have been proposed (see Patent Documents 1, 2, and 3).
- a device for shrink-fitting a member expanded by induction heating to a shaft or the like has been proposed (see Patent Documents 4 and 5).
- Patent Document 2 Japanese Patent Application Laid-Open No. 11 294465
- an object of the present invention is to provide a device which can be used for both extraction and shrink fitting in addition to miniaturization and simplification of a conventional device.
- the present invention generates a coil from induction coil.
- the magnetic field to be used is also used as a power source for attaching and detaching members.
- this repulsive force is used as power for attaching and detaching.
- the member attaching / detaching device of the present invention is a member attaching / detaching device for attaching / detaching a member to / from a shaft made of a ferromagnetic material, wherein the ring is made of a non-magnetic metal, and is disposed adjacent to the ring.
- the means for fixing the coil and the member or the ring and the member may be such that the member is hooked. It is enough to have a possible nail.
- the dynamic magnetic field generated by the coil is preferably an AC magnetic field or a pulse magnetic field in practical use.
- the excitation power supply has a function of gradually increasing the amount of current supplied to the coil as time passes, the impact of the repulsive force at the time of initial energization can be reduced.
- FIG. 3 is a perspective view of a member attaching / detaching device.
- FIG. 7 A perspective view of the use form of the device at the time of shrink fitting of components.
- FIG. 8 is a perspective cross-sectional view of a device utilization form when a member is shrink-fitted.
- FIG. 9 A perspective view of the mode of use of the apparatus during local induction heating
- FIG. 10 Perspective cross-sectional view of device utilization form during local induction heating
- FIG. 2 is a perspective view showing a member and a shaft to be attached and detached.
- the target is assumed to be the axles and bearings of track vehicles.
- the axle (axle 1) of a track vehicle is a cylinder made of a magnetic material (carbon steel, stainless steel, etc.), and has a taper and a step for shrink fitting.
- the tapered portion is drawn in a slightly exaggerated manner.
- the member 2 is a cylindrical metal bearing whose inner diameter is slightly smaller than the outer diameter of the shaft fitting portion.
- the device basically has a ring 3 made of non-magnetic metal and a coil 4 for excitation. If a material having a high electrical conductivity is used for the ring 3, a stronger repulsive force can be obtained, so that the material is preferably copper, aluminum, or the like. However, considering the weight, aluminum seems to be suitable for workability.
- the outer diameter of the ring 3 may be about the same size as the coil 4 and its thickness may be about twice as large as the "apparent thickness" determined from the frequency of the magnetic field and the conductivity of the material. . For example, if the material of the ring 3 is aluminum and an AC magnetic field of 50 Hz is used, the thickness may be about 20 mm.
- a clamp 6 is provided on the inner peripheral portion of the ring 3 as fixing means for fixing the outer periphery of the shaft 1.
- Two round bars 5 are attached to the outer periphery of the ring 3 vertically to the front of the ring.
- the round bar 5 is inserted into a round hole provided in the coil 4.
- the rod 2 as a guide, the coil 4 can freely change the distance from the ring 3 while keeping the center axis almost the same as that of the ring 3.
- the round bar 5 is provided to enhance the convenience of the apparatus, and is not always necessary.
- a claw 7 for hooking the member 2 is attached to the coil 4.
- the claw 7 has a structure that can extend and contract toward the inner periphery of the coil.
- the coil 4 is equipped with a magnetic field ON / OFF switch (not shown) and a power cable.
- the end of the power cable is connected to a power source for excitation (not shown).
- the power supply for excitation has a function of supplying a 50 Hz sine wave alternating current while gradually increasing its amplitude.
- Figure 5 shows the current waveform.
- FIG. 6 is a perspective view
- FIG. 1 is a perspective sectional view
- the shaft 1 is penetrated inside the ring 3, and similarly, the shaft 1 is also penetrated inside the coil 4.
- the coil 4 is disposed so as to be located substantially on the outer periphery of the member 2.
- the claw 8 is extended to the extent that the member 2 can be pulled.
- the member 2 is induction-heated and expanded by the magnetic field generated by the coil 4, and a repulsive force between the coil 4 and the ring 3 applies a force in the extracting direction to the coil 4.
- the member 2 is sufficiently heated and expanded, the member 2 moves together with the coil 4 in the extracting direction.
- FIG. 7 and 8 illustrate the use of the present device when shrink fitting members.
- Figure 7 is a perspective view
- FIG. 8 is a perspective sectional view.
- the device is installed on the shaft in the direction opposite to the direction at the time of removal, the coil 4 is similarly arranged so as to be located substantially on the outer periphery of the member 2, the hook 7 is hooked on the member 2, the ring 3 and the coil After adjusting the distance of (4) appropriately, fix the ring (3) to the shaft (1). Then, as in the case of the extraction, the coil is energized to induce and overheat the member 2 and pushed in the shrink fitting direction.
- FIG. 9 is a perspective view
- FIG. 10 is a perspective sectional view.
- a cylindrical magnetic shield 8 provided with a slit on the side surface is used.
- the material is a ferromagnetic material such as iron.
- This magnetic shield 8 is placed inside the coil 4 and fixed to the coil 4. At that time, one end of the magnetic shield 8 is located near the member 2, and the other end is located near the end of the shaft 1. By doing so, the magnetic field decreases inside the magnetic shield 8, and the magnetic field increases near the member 2, so that only the member 2 can be selectively heated.
- Coil 4 was a coil with an inner diameter of 100 mm and an outer diameter of 224 mm formed by winding 185 turns of copper wire.
- Ring 3 was an aluminum ring with an outer diameter of 230 mm and a thickness of 20 mm.
- As the magnetic shield 8 an SS400 pipe with a diameter of 90mm and a length of 87mm with slits in the side wall was used.
- FIG. 11 is a graph showing how the magnetic field distribution changes depending on whether or not the magnetic shield 8 is inserted inside the coil.
- the horizontal axis represents the X coordinate with the coil center axis as the coordinate axis and the end position of the magnetic shield 8 as the origin O (see FIG. 6 for details), and the vertical axis represents the magnetic field strength.
- the current flowing through the coil was 20 A (effective value)
- the curves (C, D) shown by broken lines show the magnetic field distribution without the magnetic shield 8 and the solid line.
- the curves (A, B) shown by are the magnetic field distributions when the magnetic shield 8 is used.
- B and D are the values on the coil center axis
- a and C are the values of the coil center axial force at a position 40 mm away.
- the present invention which is much smaller and simplified as compared with the conventional technology, has the same effect as the conventional technology.
