The current collector sliding material of the present invention is excellent in wear resistance and heat resistance, is hard to be softened or melted when used, and is used as a material for current collection of an electric moving body, such as a pantograph sliding plate and a crane of an electric railway.

Further, when used under extremely severe conditions, such as a pantograph of a high-speed railway vehicle, more excellent wear resistance is required. In addition to the excellent wear resistance that can withstand long-term use at high speed,
Various characteristics are also required, such as good current-carrying performance, lubricity for minimizing abrasion of the overhead wire, which is a slidable body, and mechanical strength capable of withstanding an impact received during use.

Lead is used as the main anti-friction material in casting alloys. Further, in a sintered alloy, improvement of abrasion resistance has been attempted by adding carbon or impregnating a grease material.

１枚当たりの集電量が増加することも摩耗を大きくする
要因となっている。However, due to the recent increase in speed of railway vehicles and the decrease in the number of pantographs, the load applied to the pantograph slides has become extremely large. That is, as the speed of the railway vehicle increases, the distance between the pantograph and the overhead wire increases, and arc discharge is likely to occur. Therefore, wear of the slide plate due to the arc discharge is extremely large. In addition, the number of pantographs has been greatly reduced compared to the prior art, and the resulting increase in the amount of current collected per slide plate is another factor that increases wear.

易くなり、集電面の荒れがより甚だしいものとなる。[0005] Therefore, there is a need for a slide plate having more excellent wear resistance. A slide plate made of a current-collecting sliding material having an increased content of a lubricating material such as lead, carbon, or a fat or oil component has been required. Provided. However, when the content of lead is increased, the melting point of the material is reduced, and the material is easily softened and melted by contact and friction with the overhead wire, which causes the current collecting surface to be rough. In addition, when the amount of added carbon is increased, arc discharge is more likely to occur, and the roughness of the current collecting surface becomes more severe.

Another object of the present invention is to provide a current-collecting sliding material whose current-collecting surface is hardly roughened.

Its dimensions are 45 mm in length, 20 mm in width, and 9 mm in thickness. A circumferential end surface of a copper disc having a diameter of 30 mm and a thickness of 3 mm was pressed against a substantially central portion of one of the surfaces of the test piece, and pressed and rotated at a right angle at an initial load of about 0.3 kgf.

いる。According to the results shown in Table 1, Experimental Examples 2 to 4 in which the content of tin was kept constant and the content of aluminum oxide was changed.
8, it can be seen that the specific wear amount changes depending on the content of aluminum oxide. That is, when the content of aluminum oxide is up to 0.1% by weight, the wear resistance is improved as the aluminum oxide is increased (the specific wear amount is reduced). On the other hand, when the content of aluminum oxide is 0.4
%, The specific wear starts to increase and 0.8%
It can be seen that when it is contained, the specific wear amount is almost the same as that of the conventional product of Experimental Example 12. However, a current-collecting sliding material having extremely excellent wear resistance has been obtained as compared with the case of Experimental Example 1 containing no aluminum oxide.

In particular, in Experimental Example 9 in which the tin content was lower than the lower limit of the first invention, the abrasion resistance was significantly reduced as compared with the conventional product. However, the abrasion resistance is still considerably better than that of Experimental Example 1 containing no aluminum oxide. Further, in Experimental Example 9, it is presumed that the melting point of the lead-containing conventional product is higher than that of the conventional lead-containing product, and softening and melting during use are unlikely to occur.

とが分かる。Further, in Experimental Examples 13 to 17 in which another sintered body was added in an amount of 0.3% by weight instead of aluminum oxide, the wear resistance was significantly improved even though tin was contained in an amount of 8% by weight. Don't, or rather, drop significantly. For example, in Experimental Example 14 to which TiC was added and Experimental Example 15 to which C-BN was added, although the wear resistance was improved as compared with the case of Experimental Example 1 in which aluminum oxide was not added, tin was 2% by weight. %, Which is inferior to Experimental Example 9.
Furthermore, in Experimental Example 16 using SiC, the wear resistance was significantly inferior to Experimental Example 1, and in Experimental Example 17 using MgO, the wear resistance was more significantly reduced. Thus, it can be seen that among the six types well known as ceramics, including aluminum oxide, only aluminum oxide has the function and effect of greatly improving the wear resistance.
