1、适用范围 本标准规定了外径为6到150mm的卷制轴套的主要尺寸和公差。 本标准第2条对卷制轴套作了定义和说明,是为避免与其它形状相似、而用途不同的零件相混淆,例如开口弹性圆柱销以及引起对卷制轴套的某些结构特征的注意。但是,由于制定名词术语的工作尚未完成,所以本标准中使用的所有术语都是暂时的。 由于卷制轴套的特殊性,其某些尺寸与公差不能直接测量,因此,有必要在第4条中对这些尺寸与公差规定了特殊的检验方法。 2、定义和说明 卷制轴套是由轧制材料卷制而成的、具有开口的圆柱形轴承衬垫。这个开口可以与、也可以不与圆柱体的轴线平行。在自由状态下,它可以不呈真正的圆柱形,其开口可以是张开的,当将卷制轴套装入轴承座孔后,开口就闭合了。
1, the scope of this standard specifies the outer diameter of 6 to 150mm the main dimensions of the sleeve and tolerances. Section 2 of this standard defines and describes the roll bushing in order to avoid confusion with other parts of a similar shape and of different uses such as the opening of an elastic cylindrical pin and the resulting structural features of the roll bushing note. However, since the work on the formulation of terminology has not been completed, all terms used in this standard are temporary. Due to the particularity of the roll bushing, some of its dimensions and tolerances can not be measured directly, it is necessary in Article 4 to specify a special test method for these dimensions and tolerances. 2, the definition and description Rolled bushing rolled from rolling material, with an open cylindrical bearing pad. This opening may or may not be parallel to the axis of the cylinder. In its free state, it may not be truly cylindrical, its opening may be open, and the opening will be closed when the winding sleeve is fitted into the bearing housing bore.
