电机用碳刷的尺寸、标记和试验及刷握的尺寸

[中文适用范围]： 本文件主要适用于旋转电机圆柱形换向器和滑环的刷子和刷架。本文件的某些条款可能涵盖其他配置，如扁平换向器或普通圆盘。 它定义了刷子及其组件的尺寸及其公差： - 刷块的尺寸（t, a, r）， - 角度α和β， - 倒角， - 柔性（分流器）， - 标准端子。 它还涵盖了主要尺寸的常规指定、刷子的标记以及刷子制造后的合格测试方法（不包括刷子材料等级，由IEC 60413涵盖）。 最后，它规定了与刷子相关的刷架的尺寸。 [外文原描述]： IEC 60136:2024 applies primarily to brushes and brush-holders for cylindrical commutators and slip rings for electrical rotating machines. Some clauses of this document may cover other configurations, such as flat commutators or plain disks. It defines the dimensions of brushes and their components, together with their tolerances: - dimensions of brush block (t, a, r), - angles α and β, - chamfer, - flexibles (shunts), - standard terminals. It also covers the conventional designation of principal dimensions, the marking of brushes and the testing methods for the qualification of brushes after their manufacturing (except the brush grade material, covered by IEC 60413). This third edition cancels and replaces the second edition published in 1986 and Amendment 1:1995. This edition constitutes a technical revision. Please refer to the Foreword of the document for a comprehensive listing of the changes with respect to the previous edition.
