Abstract
The utility model discloses a double-end fixed brush rod structure. Multiple groups of brush rods supported by support pieces are distributed on the outer periphery of a conducting ring. Each of the brush rods connects with an electric brush through an adapter plate. The electric brushes are disposed in a position of the inner periphery of the conducting ring. Two ends of each of the brush rods are both provided with threads. One end of each of the brush rods is fixed on the support piece while the other end of each of the brush rods is fixed together with a front wall of a motor brush support cover through a hexagon nut and a connection plate. The double-end fixed brush rod structure in the utility model is simple and compact in structure and is practical and convenient. Through the effective support on the two ends, the fixed structure of the brush rods and the motor brush support cover is reinforced, thereby effectively solving a problem that the vibration of the motor brush support cover is comparatively serious in a large or middle size winding asynchronous motor, improving the testing yield of a motor, and prolonging the service lifetime of the motor and the brush rods.
Description
Technical field
The utility model relates to technical field of motors, especially the fixing brush holder support structure of double end.
Background technology
In most in the market large and medium-sized wire-wound asynchronous motors; Employed brush holder support structure of fixing with the brush holder cover is the single head fixed structure; Be that of brush holder support is fixed on the antetheca of brush holder cover, the other end is unsettled, and the brush holder support fixed structure of this beam type is beated because of the motor sliding ring surface through regular meeting; And cause beating of the brush that is fixed on the brush holder support, and then cause the vibration of whole brush holder support structure and motor brush rocker cover bigger.
The utility model content
The applicant is prone to produce shortcomings such as motor oscillating to the brush holder support fixed structure of above-mentioned existing beam type, and fixedly brush holder support structure of a kind of double end rational in infrastructure is provided, thereby reduces the vibration of motor brush rocker cover and brush holder support, thus the pass the test rate of raising motor.
The technical scheme that the utility model adopted is following:
A kind of double end is the brush holder support structure fixedly; The excircle of conducting ring is evenly equipped with the some groups of brush holder supports through support member; Be fixed with brush through keyset on every brush holder support, brush is positioned at the inner periphery position of conducting ring, and the brush holder support two ends are provided with screw thread; One end is fixed on the supporter, and the other end is fixed together through the antetheca of hex nut, connecting plate and motor brush rocker cover.
The beneficial effect of the utility model is following:
The utility model is simple in structure, compact, practical and convenient; Effective support through two ends; Strengthened the fixed structure of brush holder support and motor brush rocker cover; Solve the normal bigger problem of motor brush rocker cover vibration that exists in the large and medium-sized wire-wound asynchronous motor effectively, improved the pass the test rate of motor and the useful life of motor brush.
Description of drawings

Fig. 2 is the sketch map of the utility model after installing.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described.
Like Fig. 1, shown in Figure 2; The excircle of conducting ring 6 is evenly equipped with the some groups of brush holder supports 1 that support through supporter 5; Be fixed with brush 4 through keyset on every brush holder support 1, brush 4 is positioned at the inner periphery position of conducting ring 6, and brush holder support 1 two ends are provided with screw thread; One end is fixed on the supporter 5, and the other end is fixed together with the antetheca of motor brush rocker cover through hex nut 2, connecting plate 3.Through the fixing brush holder support structure of this double end, increased the constant intensity of brush holder support effectively, reduced the vibration of brush holder support and beating of conducting ring power up brush.
Claims (1)
