Abstract

The utility model relates to a brush electric machine separating commutator. The circular column which is composed of the mutual insulating red copper piece, is separated with the column head. Each red copper piece which is tightly sleeved on the column head of the electric machine rotor shaft, is welded with the correspondingly motor coil winding. The circular column which is in sliding sleeved on the electric machine rotor shaft and is composed of the mutual insulating red copper piece, is integrally connected with the column head which is tightly sleeved on the electric machine rotor shaft by an inner hexagon socket-head bolt penetrating the positioning bolt hole. The circular column surface is abraded after the sliding contact with the electric brush, as long as the bolt is screwed off and a new circular column is replaced, which is very convenient. The utility model has the advantages of novel structure, convenience dismounting and cheap cost.
本实用新型涉及一种有刷电机分体式换向器,由相互绝缘的紫铜片组成的圆柱和柱头是分体的,紧固套装在电机转子轴上的柱头上的每个紫铜片都与对应的电机线圈绕组相焊接。滑动套装在电机转子轴上、由相互绝缘的紫铜片组成的圆柱,依靠内六角头螺栓穿过定位螺孔与紧固套装在电机转子轴上的柱头连接成一体。与电刷滑动接触的圆柱面磨损后,只要拧开螺栓,更换一个新的圆柱,非常简便。本实用新型具有结构新颖、拆装方便、成本低廉的优点。
