摘要： In a multilayer brush composed chiefly of copper and graphite and incorporated therein with a solid lubricant, which consists essentially of two types of brushes, a high-copper-content part brush containing the copper in a large quantity and a low-copper-content part brush containing the copper in a small quantity, at least the high-copper-content part brush contains zinc in an amount of from 0.1% by weight to 5% by weight, and the zinc and the copper form an alloy. This can provide a multilayer brush having a superior durability, which can prevent the performance of motors from lowering, without use of the harmful substance such as lead, and may less undergo any wear due to mechanical and electrical sparkling of the brush.

摘要： In a rotary electric machine, a collar for restricting expansion of coil ends includes a boss fitted on an armature rotation shaft, a flange radially extending from the boss and a pressing portion for pressing coil ends toward an armature core. The thickness of the boss is greater than that of the flange, so that the force F1 that is caused by deflection of the flange when coil ends expand due to a temperature increase is smaller than the force F2 that is required to remove the boss from the rotation shaft. The force F1 is applied to the boss in a direction that the collar separates from the armature core. Because the pressing portion presses against the coil ends toward the armature core through an insulation ring, the coil ends are restricted from expanding by a centrifugal force when the armature rotates.
摘要翻译：在旋转电机中，用于限制线圈端部的膨胀的轴环包括安装在电枢旋转轴上的凸台，从凸台径向延伸的凸缘和用于将线圈端朝向电枢铁心按压的按压部。凸台的厚度大于凸缘的厚度，使得当线圈端部由于温度升高而膨胀时由法兰的偏转引起的力F1小于将凸起从该凸起移除所需的力F2 旋转轴。力F1沿轴环与电枢铁芯分离的方向施加到凸台。由于按压部分通过绝缘环将电枢铁芯的线圈端部压向电枢铁心，所以当电枢旋转时，线圈端部被离心力限制。
