Problems solved by technology

[0002] In most large and medium-sized wound asynchronous motors currently on the market, the brush rod structure used to fix the brush holder cover is a single-head fixed structure, that is, one end of the brush rod is fixed on the front wall of the brush holder cover, and the other end is suspended in the air. , this cantilever beam-type brush rod fixing structure often causes the brush fixed on the brush rod to jump due to the surface jump of the motor slip ring, which in turn causes the vibration of the entire brush rod structure and the brush holder cover of the motor to be large

Embodiment Construction

[0010] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 , figure 2 As shown, the outer circumference of the conductive ring 6 is evenly distributed with several groups of brush rods 1 supported by the support member 5, and each brush rod 1 is fixed with a brush 4 through an adapter plate, and the brush 4 is located on the inner circumference of the conductive ring 6 position, both ends of the brush rod 1 are provided with threads, one end is fixed on the support member 5, and the other end is fixed together with the front wall of the motor brush holder cover through the hex nut 2 and the connecting plate 3. Through this double-head fixed brush rod structure, the fixing strength of the brush rod is effectively increased, and the vibration of the brush rod and the jumping of the brush on the conductive ring are reduced.

Abstract

The present invention discloses a fixed double-headed brush-holder stud structure which is characterized in that: outer circumference of a conductive ring is uniformly provided with a plurality of groups of brush-holder studs which are supported by supporting parts, each brush-holder stud is fixed with an electric brush through an adapter plate, the electric brush is at inner periphery of the conductive ring, two ends of the brush-holder stud are provided with screw thread, one end if fixed at the supporting part, and the other end is fixed with an anterior wall of a motor brush frame cover through a hex nut and a connecting plate. The invention has the advantages of simple and compact structure, practicality and convenience, through effect support of the two ends, a fixed structure of the brush-holder studs and the motor brush frame cover is enhanced, a problem of large motor brush frame cover vibration existed in large and medium-sized wound asynchronous motors is effectively solved, a test passing rate of a motor is raised, and a service life of the electric brush is prolonged.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a double-headed fixed brush rod structure. Background technique [0002] In most large and medium-sized wound asynchronous motors currently on the market, the brush rod structure used to fix the brush holder cover is a single-head fixed structure, that is, one end of the brush rod is fixed on the front wall of the brush holder cover, and the other end is suspended in the air. , This cantilever beam-type brush rod fixing structure often causes the brush fixed on the brush rod to jump due to the surface jump of the motor slip ring, which in turn causes the vibration of the entire brush rod structure and the brush holder cover of the motor to be large. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned existing cantilever beam-type brush rod fixing structure, which is prone to motor vibration, etc., the applicant provides a double-headed fixed brus...
