The beneficial effects of the utility model are：By setting V-groove on conducting ring, thus brush wires and conducting ring connect Touch the restricted number of degrees of freedom, of region institute more, can not only limit axial float when conducting ring is contacted with brush wires, can Ensure conducting slip ring steady operation in vibration, impact, centrifugation or other harsh environments, it is ensured that the stabilization of contact Property, while noise performance can also be improved, improve conducting slip ring resistance external environmental ability.In addition, by being set on stator Neck is put, in the neck that brush plate is arranged on to stator, so that in the case where brush wires are worn and torn, brush plate only need to be changed i.e. Can, so as to largely save the cost of material and reduce maintenance cost.

In some embodiments, multigroup brush wires hole is offered on brush plate, one end of brush wires is welded on brush wires In hole.Thus, it is possible to simplify the structure of brush plate, while manufacturing procedure can also be reduced, so as to reduce production cost.

In some embodiments, the material of bearing is ceramics.Thus, it is possible to the magnetic flux of conducting slip ring is substantially reduced, The requirements for life required for no magnetic machine can be reached, halfway without changing.

In some embodiments, the material of insulation spacer ring is plastics.Thus, it is possible to greatly improve the insulation of insulation spacer ring Effect, improves structural stability of the present utility model.

In some embodiments, shell is that upper shell and lower house docking are formed.Thus, assembling more facilitates, significantly Labor strength is reduced, built-up time is saved.

In some embodiments, the surface of brush wires and V-groove is provided with conductive lubricating oil lipid layer.Thus, it is possible to reduce Abrasion of the brush wires to conducting ring, improves brush wires and the service life of conducting ring, the replacing of reduction brush wires and conducting ring is frequently It is secondary, so that effectively save production cost.

Brief description of the drawings

Fig. 1 is a kind of overall structure diagram of conducting slip ring with V-groove copper ring of the embodiment of the utility model one；

Fig. 2 is a kind of structural representation of the brush plate of the conducting slip ring with V-groove copper ring shown in Fig. 1.

Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

Fig. 1 schematically shows a kind of conduction with V-groove copper ring according to a kind of embodiment of the present utility model Slip ring, Fig. 2 very diagrammatically show a kind of brush plate of conducting slip ring with V-groove copper ring shown in Fig. 1.As illustrated, this is led Electric slip ring includes stator 1, rotor 2, bearing 3, shell 4, insulation spacer ring 5, brush plate 6 and conducting ring 7.

The wherein inner side of stator 1 connects rotor 2 by bearing 3.The material of bearing 3 is ceramics.Led thus, it is possible to substantially reduce The magnetic flux of electric slip ring, is that it can reach the requirements for life required for no magnetic machine, halfway without changing.
