Abstract
The utility model discloses a motor brush holder, consisting of a shell (1), a pressing spring frame (2) and a pressing spring (3). The pressing spring frame(2) shaped as 'N' is inserted into the shell(1).The pressing spring frame(2)is fixed with the pressing spring(3) therein. The pressing spring (3) is a spiral spring. One side of the pressing spring frame (2) is an elastic tablet with a chuck (5). The shell (1) is arranged with a block shaft (6) therein corresponding with the chuck (5). The utility model adopts the spiral spring, which presses against the electric brush to maintain the lasting constant pressure. When the pressing spring frame is inserted into the shell, the elastic tablet is only needed to be pressed to insert and the chuck is made to be buckled with the block shaft so that the purpose of fixation can be achieved. The installation and the dismantlement of the electric brush are convenient and the operation is easy.
Description
Affiliated technical field
The utility model belongs to a kind of motor component, is a kind of brush carrier of direct current machine particularly.
Background technology
Brush and brush carrier are the critical pieces of motor, and brush not only requires to conduct electricity very well, and require the electric current distributed uniform, and commutation ability is good, and film forming ability is strong.When being satisfied with condition of work, the necessary servo-actuated of brush is good, and motor rotates, the necessary servo-actuated of the transmission of electricity function of brush, have the good dynamic sliding contact could runs steadily, brush must have balanced suitable pressure to keep and the contacting of commutator in box.Pressure is too small, and the brush loose contact of beating produces electric spark burn commutator, and pressure is excessive to cause commutator and brush is overheated and wearing and tearing strengthen.Therefore, brush carrier is very crucial to the fixing of brush with cooperating.In the prior art, adopt spiral spring to press brush in the brush carrier,, influence operate as normal along with the wearing and tearing spring pressure of brush reduces gradually.Spiral spring is fixed in the brush carrier by support, complex structure, dismounting and change brush inconvenience.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved motor brush carrier is provided, and it is simple in structure, and brush is easy to loading and unloading, keeps the constant voltage to brush, and result of use is good.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model includes: shell, stage clip frame, stage clip, it is characterized in that: the stage clip frame is " N " font, insert in the shell, be fixed with stage clip in the stage clip frame, stage clip is a wind spring, and a side of stage clip frame is a bouncing plate, bouncing plate has dop, and it is corresponding with dop to be provided with axis in the shell.
The utility model is taked technique scheme, has following beneficial effect: the utility model when it presses brush, is not subjected to the limitation of wear of brush owing to adopt wind spring, can keep lasting constant pressure.When the stage clip frame inserts shell, only need push bouncing plate and make it to insert, and make dop and axis clamping mutually, reach fixing purpose.During dismounting, push bouncing plate dop and axis are thrown off, extract the stage clip frame out and get final product.Therefore, the loading and unloading brush is convenient, easy to operate.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the utility model structure diagram.
Mark among the figure: 1-shell, 2-stage clip frame, 3-stage clip, 4-bouncing plate, 5-dop, 6-axis
Embodiment
By shown in Figure 1, the utility model includes: shell 1, stage clip frame 2, stage clip 3, stage clip frame 2 is " N " font, insert in the shell 1, be fixed with stage clip 3 in the stage clip frame 2, stage clip 3 is a wind spring, and a side of stage clip frame 2 is a bouncing plate 4, bouncing plate 4 has dop 5, and it is corresponding with dop 5 to be provided with axis 6 in the shell 1.Stage clip frame 2 of the present utility model can adopt the hardboard frame internal fixation stage clip 3 of " n " font, the be fixedly connected bouncing plate 4 of " V " font of hardboard frame one side, thus form " N " font.About 2 two corresponding inserting in the shell of stage clip frame of the present utility model.
