Abstract
The invention discloses an electric brush structure of a direct-current motor. The electric brush structure comprises a brush frame seat, a brush rod, a conductive bar, a conductive ring and a carbon brush unit, wherein one end of the brush rod is arranged on the brush frame seat, the conductive bar is arranged on the brush rod, the conductive ring is connected on the conductive bar, and a carbon brush of the carbon brush unit is fixed on the brush rod through a brush holder; and the other end of the brush rod is fixed on a brush ring. The electric brush structure is simple, compact and reliable, and has obvious effect; and under the conditions of keeping the cost of the motor and ensuring the safety and the reliability of the motor, a brush ring device is added at the brush rod end part of a brush frame to play a role in protecting the brush rod, improve the rigidity of the brush rod and reduce the problems of non-uniform abrasion of the carbon brush, motor spark and the like.
Description
Technical field
The present invention relates to a kind of brush structure, belong to machine field.
Background technology
Common Z series middle size motor, brush holder support directly is fixed on brush rack base, only rely on the support of brush rack base, less in the commutator working diameter, during the brush negligible amounts, the rigidity of brush holder support itself can meet the demands, but the commutator working diameter of Z900, Z1000 motor is larger, and its brush quantity is generally more, and brush holder support is relatively long, and slight shake may appear in brush holder, integral rigidity weakens, can cause the brush discontinuity, wear extent is inhomogeneous, can cause the adverse consequencess such as spark, noise during the motor normal operation.
Summary of the invention
The technical problem to be solved in the present invention is the defective that overcomes existing brush structure, provides a kind of brush holder support rigidity good, the uniform brush structure of carbon brush abrasion.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of electric brush structure of DC motor, comprise brush rack base, brush holder support, busbar, conducting ring, carbon brush unit, brush holder support one end is installed on the brush rack base, and busbar is installed on the brush holder support, conducting ring is connected on the busbar, and the carbon brush of carbon brush unit is fixed on the brush holder support by brush carrier; The described brush holder support other end is fixed on the brush ring.The brush ring material is preferably epoxy resin bonded fiber.
Because Z900, Z1000 power of motor are higher, brush holder support is longer, and the brush quantity on each brush holder support is more, and slight jitter may occur, reduced stiffness, brush discontinuity.The present invention is fixed at former brush rack base on the basis of electric motor end cap, is fixed on the brush ring in other end brush holder support end again, has effectively protected brush holder support, has improved the globality of brush holder.
Further, described brush ring is fixed on the brush holder support by fillister head screw, is coated with the seal ring epoxy resins on the described fillister head screw.Because the brush ring end face near commutator riser (material is copper plate), need to insulate it, avoid conduction, so will be coated with the seal ring epoxy resins.
This brush structure is simple, compact, and reliable, action effect is obvious; Do not increasing motor cost; guaranteeing increases by a brush ring device by the brush holder support end at brush holder under the condition of motor safety and reliability, can play the effect of protection brush holder support; improve the rigidity of brush holder support, can reduce again the problems such as the carbon brush abrasion amount that produces therefrom is inhomogeneous, motor spark.
