DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for lubricating current supply and current collecting members, and more specifically to a method for lubricating electrically complex wear including sliding contact wear caused by a combination of a contact plate and a trolley wire in pantographs, etc. of electric railways. As a preventive measure against this phenomenon, contact lubricant is used to automatically apply an appropriate amount of lubricant to these parts without damaging the electrical effect during current collection, thereby extending the period of use. The present invention relates to a method of lubricating a current collecting member.

This is a problem of wear in sliding contact, but the main usage conditions that affect this are vehicle speed, fluctuations in the uplifting force of punctures due to vibration, fluctuations in current collection, and furthermore, track,
Possible causes include arcing during intermittent disconnection caused by a complex combination of conditions such as vehicle, speed, and condition of the puncture, as well as lubricant and weather conditions.

In particular, in the case of a pantograph-type current collector for trains, etc., the contact plate and the trolley wire always slide in the same position, creating grooves in the contact plate due to wear. To prevent this, the trolley wire is The trolley wire is stretched in a waveform in the horizontal direction so that the trolley wire does not always contact the slider plate at the same position, and the slider plate and the trolley wire slide in the left-right direction and simultaneously move in the front-rear direction.

この様に数多くの要因が複雑に関与しているため、すり
板とトロリー線の摩耗を低減する適確な潤滑は非常に困
難である。
As such, many factors are involved in a complex manner, making it extremely difficult to provide appropriate lubrication to reduce wear between the contact plate and the trolley wire.

すり板は集電すべり接触をするのであるから、基本的な
特性として次のことが要求される。

In other words, (1) it must have sufficient mechanical strength to withstand impact forces such as fluctuations in contact force at high speeds, and (2) it must have low specific resistance (including contact resistance) and can handle large currents. (3) There is no risk of heating and fusing the trolley wire when collecting current.
(4) The contact wire itself does not wear out; (5) the coefficient of friction is small and its fluctuation is small; and (6) it has good heat resistance and arc resistance.

Some slider materials have added self-lubricating properties, but
Any of these combinations does not satisfy all of the above-mentioned basic characteristics.

For example, cast alloy contact plates have sufficient mechanical strength and good electrical properties, but they cannot be expected to have the same lubricity as sintered alloy contact plates, so a lubricant such as grease is used to connect the contact plate. In some cases, it is possible to prevent a significant increase in wear on the trolley wire, but it is almost impossible to supply the appropriate amount of lubrication at the right time with conventional methods, and the quality of the method is only determined by data from laboratory experiments.

Sintered metal contact plates have also been developed for the purpose of adding self-lubrication, but these have not yet reached a satisfactory level in terms of strength and electrical properties.

On the other hand, carbon contact plates are not generally used because they have poor conditions in all aspects, but the most important advantage is that they do not wear out the trolley wire, and the wear rate of the contact plate itself is lower than that of sintered alloy contact plates. We have discovered a remarkable phenomenon that is comparable to when using .

Recently, there has been a tendency for wear on sliders and trolley wires to increase due to increases in electrified sections, train density, train speed, and current collection. Attempts have been made to solve the problem by combining current supply and current collection members, but no solution has been found.

Therefore, it is essential to add an appropriate lubricant to the supply and current collection members as needed, and it is also a shortcut to solving the problem.

In the present invention, the four ends of the yoke on the N-pole side are made of a non-magnetic reservoir 5 to more effectively collect the magnetic flux density, which is the purpose of providing the yoke.
In other words, they cannot be gathered at the tip cross section of the yoke 4, which is a magnetic induction material, and are physically obstructed, so that the magnetic attraction of the magnetic fluid 6 is attenuated.

In other words, this does not mean that the terminal effect of the magnetic field lines is attenuated to zero, but because the yoke terminal on the N pole side, which further collects the magnetic flux density, is connected to the non-magnetic reservoir 5, the magnetic field in this part is affected by the magnetic fluid. This means that physical suction is reduced.

However, since the magnetic field line at position 8 is sufficiently affected by the effect of yoke 4, the magnetic fluid flowing due to the magnetic field has a maximum magnetic flux density at the tip of yoke 4 on the S pole side, so the magnetic flux in reservoir 5 The fluid 6 is first positioned on the side wall of the magnet, then on the slit 7 and along the flow of the magnetic lines of force, and is temporarily positioned at a position 8 where the magnetic flux density is high.

The magnetic fluid 6 with lubricating oil as a dispersion medium is continuously and automatically attracted to position 8 by magnetic energy, and the ferromagnetism coexisting in the magnetic fluid 6 is Spike is formed with the dispersion medium oil with lubricating properties contained in the ultrafine particles (100 FeO, Fe304 particles) of the body.

The shape of this spike is such that the propagation of surface waves is controlled by the magnetic field in the tangential direction due to the characteristics of the magnetic fluid, and it resembles a hexagonal swivel with the sharp end of a nail pointing upwards, and the tip of the yoke is a magnetic conductor. The cross section is the base,
Its height and base are proportional to the magnetic flux density.

Therefore, the magnetic fluid 6 that spikes and swells from position 8 will definitely come into contact with the slider plate 1 and the trolley wire 9.
When they slide, they are physically peeled off toward the trolley wire 9 and consumed in small amounts, thereby establishing conditions for boundary lubrication between the trolley wire 9 and the slider plate 1.

Here, boundary lubrication refers to the structure of a unique lubricant film that protects friction surfaces due to various disturbances of friction, that is, the limit to which the boundary layer participates in the lubrication effect. This is because each friction characteristic is created by a mixture of large friction elements with different qualities of friction and dry friction.

Therefore, as shown in FIG. 2, if the above-described structure according to the present invention is installed on the side surface of the slider plate 1 in the direction perpendicular to the surface intersecting the trolley wire 9, the magnetic fluid 6 will be drawn into the reservoir 5 due to the structure of the magnetic circuit. From then on, it automatically crawls around the magnet, the amount of movement is adjusted by the slit 7, and it is positioned in a spike-like position at position 8.

流体の移動量の調整は磁束密度の増減によっても可能で

The amount of movement of the fluid can also be adjusted by increasing or decreasing the magnetic flux density.

Furthermore, regarding the replenishment of fluid, it is also conceivable to utilize the side surface of the reservoir 5 that does not interfere with the sliding surface, and to inject the fluid by utilizing an air pressure difference or wind pressure.
