Abstract
The utility model relates to a brush holder, which can prevent the spring from being hit out by the rotating motor commutator, and comprises a brush holder copper tube used for containing the brush carbon and the spring, wherein a stop section is formed on the bottom of the brush holder copper tube, and a pylome is arranged on the center of the stop section, the brush carbon can go through the pylome but the spring cannot. The utility model also relates to a motor commutating brush component which adopts the brush holder, wherein a spring is arranged inside the brush holder copper tube; one end of the spring is connected with the brush carbon, while the other end of the brush carbon goes through the pylome of the stop section at the bottom of the brush holder copper tube. For the bush holder of the utility model, as the stop section is arranged at the bottom of the brush holder copper tube, along with the brush carbon gradually wearing shorter, the carbon and the spring gradually decline to the limit position, but the spring can not continue to extend with the abrasion of the brush carbon because of the block of the stop section. The utility model prevents the spring from being hit out by the rotating motor commutator and avoids the personal accident and the motor damage while the flying out spring touches the electric motor commutator.
Description
Technical field:
The utility model belongs to motor spare and accessory parts technical field, is specifically related to motor commutation brush positioner.
Background technology:
Brush direct current machine with exchange series excited machine in use very extensive.Existing structure normally places brush carrier with brush and spring, by spring a pretightning force is arranged between brush and the brush carrier, and brush is connected with power supply by the brush pigtail.After brush work a period of time of this kind structure, because of motor rotation, rub between commutator and the motor, the brush carbon body weares and teares gradually and shortens, and the engine commutator that spring is rotated easily is up to, thereby jeopardizes personal safety or touch engine commutator and damage motor.
The utility model content:
The purpose of this utility model provides the brush carrier that a kind of engine commutator that can stop spring to be rotated is up to.
Another purpose of the present utility model provides a kind of motor commutation brush assembly of electric that adopts described brush carrier.
The technical solution of the utility model is as follows:
A kind of brush carrier comprises the brush carrier copper pipe that is used for ccontaining brush carbon body and spring, and brush carrier copper pipe bottom is formed with the stopper section, and these stopper section central authorities are provided with and can pass but the through hole that can not the ammunition feed spring passes for the brush carbon body.
Described brush carrier copper pipe bottom outside also is provided with commutation power supply connecting portion.This power supply connecting portion can be the circle groove that brush carrier copper pipe bottom outside forms.
Described brush carrier copper pipe upper outside can also be provided with the brush carrier body by fixed cover, and brush carrier copper pipe top is provided with dismountable brush carrier cap, and this brush carrier cap and brush carrier copper pipe top push against.This mode of pushing against can be: the brush carrier cap is to be fixed on the brush carrier body in the screw-in mode.
A kind of motor commutation brush assembly of electric adopts described brush carrier, the built-in spring of described brush carrier copper pipe, and spring one end is connected with the brush carbon body, and the brush carbon body other end passes the through hole in the brush carrier copper pipe bottom stop portion.
Brush carrier of the present utility model, because its brush carrier copper pipe bottom is provided with the stopper section, when wearing and tearing gradually, the brush carbon body shortens, carbon body and spring descend gradually, during extreme position, spring is stopped by brush carrier copper pipe stopper section, and spring can be because of the wearing and tearing of brush carbon body continue elongation, and the engine commutator of avoiding being rotated is up to jeopardize personal safety or to touch engine commutator and damage motor.Simultaneously, spring stops to exert pressure to brush, so that after the motor dead electricity, the user knows the replacing brush.
Description of drawings:
Fig. 1 is the brush carrier structural representation.
Fig. 2 is the brush assembly of electric structural representation.
Among the figure, 1-brush carrier body, 2-brush carrier cap, 3-brush carrier copper pipe, 4-stopper section, 5-through hole, 6-groove, 7-spring, 8-brush carbon body, 9-brush pigtail, 10-copper sheet.
Embodiment:
As depicted in figs. 1 and 2, brush carrier comprises the brush carrier copper pipe 3 that is used for ccontaining brush carbon body and spring, brush carrier copper pipe 3 is punching press copper sheet spare structure, and the 3 bottom punching press shear formings of brush carrier copper pipe form stopper section 4, and these stopper section central authorities can pass but the through hole 5 that can not the ammunition feed spring passes for the brush carbon body.Brush carrier copper pipe 3 bottom outside are formed with a circle groove 6, in order to fixing and commutation power supply wire connecting.Brush carrier copper pipe 3 upper outside fixed covers are provided with brush carrier body 1, and brush carrier copper pipe 3 tops are provided with dismountable brush carrier cap 2, and this brush carrier cap 2 is fixed on the brush carrier body 1 in the screw-in mode.
As shown in Figure 2, the motor commutation brush assembly of electric, adopt brush carrier as shown in Figure 1, brush carrier copper pipe 3 built-in springs 7, spring 7 one ends are connected with brush carbon body 8, and brush carbon body 8 passes the through hole 5 in the brush carrier copper pipe 3 bottom stop portions 4, brush carbon body 8 connects brush pigtail 9, brush pigtail 9 length are greater than the length of spring 7, and the other end of brush pigtail 9 is connected with a copper sheet 10, and this copper sheet 10 pushes against by brush carrier cap 2 and is fixed between brush carrier cap 2 and brush carrier copper pipe 3 tops.
Brush assembly of electric can be finished by assembling, and brush carrier copper pipe 3 is packed in the brush carrier body 1, refills power up brush carbon body 8, spring 7, copper sheet 10, screws in brush carrier cap 2 then, just forms brush assembly of electric.
