摘要： A brush holder for dynamo-electric machine has the following parts: a brush making sliding contact with the surface of a rotary collector; a stationary holder part fixed to the stationary part of the dynamo-electric machine opposite to the collector; and a detachable holder part detachably secured to the stationary holder part and holding the brush when separated from the stationary holder part, the detachable holder part being provided with a retainer that clamps the brush when the detachable holder part is separated from the stationary holder part and unclamps the brush when it is attached to the stationary holder part, the brush clamping portion and the portion of the retainer therearound being coated with a coating film of a material having a friction coefficient smaller than the material of the retainer. This arrangement obviates various unfavorable phenomena such as jumping of the brush, sparking on the sliding surface, cracking in the brush and so forth.

摘要： A brush holding apparatus for a rotary electric machine permitting removal and replacement of brushes without stopping the rotation of the rotary electric machine comprises a brush holder which can be detached from a stationary unit, and a securing device for detachably securing the brush holder to the stationary unit. A manipulating lever is provided on the stationary unit to actuate the securing device. The brush holder can easily be mounted on or detached from the stationary unit by the manipulation of the manipulating lever for the puppose of removal and replacement of the brushes while the rotary electric machine is in operation.

摘要： A slip ring cooling device for electrical rotary machine comprises a plurality of closed chambers axially extending in the peripheral portion with intervals therebetween in the peripheral direction, and an annular passage at one side. The closed chambers each are defined by the surfaces of holes made in the slip ring so as to axially extend at the peripheral portion of the slip ring. The axially extended holes have open ends and closed ends. The annular passage is fluidly connected to each of said open ends so that said closed chambers communicate with said annular passage. A volatile liquid poured in said passage is distributed uniformly to each of said closed chambers by centrifugal force applied thereon upon the rotation of the slip ring. The distributed liquid is evaporated by the slip ring and brushes contacting the slip ring to form vapor. The vapor is transferred to the lower temperature portion by the pressure difference to be cooled and condensed, whereby the slip ring is cooled.
摘要翻译：一种用于电动旋转机械的滑环冷却装置，包括沿圆周方向间隔地在周边部分轴向延伸的多个封闭腔和一侧的环形通道。封闭室各自由滑环中形成的孔的表面限定，以便在滑环的周边部分轴向延伸。轴向延伸的孔具有开口端和封闭端。环形通道流体地连接到每个所述开口端，使得所述封闭室与所述环形通道连通。浇注在所述通道中的挥发性液体通过在滑环旋转时施加在其上的离心力而均匀分布到每个所述封闭腔室中。分配的液体被滑环蒸发，刷子与滑环接触形成蒸气。蒸气通过压差传递到较低温度部分进行冷却和冷凝，由此滑环被冷却。
