    • PURPOSE:To process each segment piece continuously by forming the segment pieces to a proper shape so that each segment piece can be connected and processed until the commutator is completed from a tabular blank as segments. CONSTITUTION:The commutator consists of an insulating base body A and the segment pieces B. The insulating base body A is formed by a cylinder section 1 and a collar section 2 projected to one side of the cylinder section, radial grooves 4 are formed to the collar section 2, and receiving grooves 5 are formed to the cylinder section 1. With the segment bodies B, the outer circumferential surfaces of the cylinder section 1 of the insulating base body A are covered with them while they are formed by segment plate sections 6, one ends thereof are inserted into receiving grooves 3 on the collar section 2 side, pawl plate sections 7 for connection, which are bent from the inserting ends of the segment plate sections 6, pass through the radial grooves 4 of the collar section 2 and are projected to the outside of the collar section 2, and connecting pawl sections 8, which are bent from the cylinder port sides of the segment plate sections 6 and inserted into the receiving grooves 5 of the end surfaces of the cylinder ports.
    • 目的:通过将片段形成适当的形状来连续处理每个片段,使得每个片段可以被连接和处理,直到换向器从片状空白完成为片段。 构成:换向器由绝缘基体A和段片B构成。绝缘基体A由圆筒部1和突出于圆筒部的一侧的凸缘部2形成,径向槽4形成为 轴环部分2和接收槽5形成在气缸部分1上。通过分段体B,绝缘基体A的圆筒部分1的外圆周表面被它们分隔成一个分段板部分6 其一端插入到凸缘部2侧的接收槽3中,从分段板部6的插入端弯曲的用于连接的棘爪板部7穿过套环部2的径向槽4, 突出到套环部分2的外侧,以及连接棘爪部分8,其从分段板部分6的气缸端侧弯曲并插入到端部的容纳槽5中 气缸端口的表面。
