Fig. 2 is the exploded perspective view at a visual angle of this utility model preferred embodiment.
Fig. 3 is the exploded perspective view at another visual angle of this utility model preferred embodiment.
Detailed description of the invention
Name preferred embodiment, and combine accompanying drawing and become apparent from intactly illustrating this utility model.
As shown in Figure 1, Figure 2 and Figure 3, the brake structural of a kind of motor, it includes motor body 10, is located at motor body
Rear end cap 11 on 10 and the power transmission shaft 12 of motor body 10 driving；Frictional disk 20, brake disc it is sequentially provided with on rear end cap 11
30, armature disc 40 and yoke 50, is sequentially provided with location dish 60 and rotating disk 70 between frictional disk 20 and armature disc 30；Location dish 60
Brake disc 30 all it is sheathed on rotating disk 70；Yoke 50 and location dish 60 by hollow bolt 13 and match with hollow bolt 13
The hexagon socket cap head screw 14 closed is fixed on rear end cap 11.
Yoke 50 is internal is provided with coil 51 and holddown spring 52, and holddown spring 52 is connected to armature disc 40.Brake disc 30 is overlapped
It is located at power transmission shaft 12；Being provided with spline housing 15 between brake disc 30 and power transmission shaft 12, spline housing 15 is fixedly arranged on power transmission shaft 12.
On the face that brake disc 30 is relative with frictional disk 20, brake disc 30 be equipped with friction plate on the face relative with armature disc 40
31.As such, it is possible to increase the frictional force between brake disc and frictional disk, between brake disc and armature disc, improve braking ability.
It is equipped with support 61 on armature disc 40 and location dish 60, two stands 61 is connected with handle 80；The end of handle 80
Being provided with first gear teeth 81, rotating disk 70 is provided with second gear teeth 71 being meshed with first gear teeth 81.
Back-moving spring 41 it is provided with between armature disc 40 and rotating disk 70；Armature disc 40 is provided with the bullet accommodating back-moving spring 41
Spring holding tank, one end of back-moving spring 41 is fixed on armature disc 40, and the other end is fixed with rotating disk 70 by holding screw 72.
Being additionally provided with arcuate groove 73 and the steel ball 74 being located in arcuate groove in rotating disk 70, steel ball 74 is connected to location dish
60。
Armature disc 40 is provided with rolling element 42, and rotating disk 70 is provided with for accommodating the rolling groove 75 that rolling element 42 rolls,
The bottom of rolling groove 75 is slope.Rotate when handle 80 is rotated dish 70 and makes rolling element 42 from the minimum point on slope to the highest
When point rolls, armature disc 40 moves near yoke 50 direction；When back-moving spring 41 resets and make rolling element 42 from slope
High point is when minimum point rolls, and armature disc 40 moves to leaving yoke 50 direction.
When needing release after motor braking, can be by the coil electricity in yoke, yoke produces suction, by armature
Dish holds, thus realizes the release of braking.
When motor power-off, it is impossible to the braking being realized motor by yoke is discharged.Now, handle is radially pulled, hands
Grip strip is moved rotating disk and is rotated so that rolling element rolls to peak from the minimum point on slope, and then makes armature disc near magnetic
Bound conjugate moves so that armature disc separates with brake disc, and power transmission shaft discharges.When release handle, back-moving spring is multiple by rotating disk
Position.
Visible, this electromotor brake has quickly release and the advantage of brake component Rapid reset of braking.
No matter this motor is installed on how high height, only need to pull up a hawser at handle, when brake needs manually
During release, personnel pull hawser on the ground below motor, just can brake be discharged.Therefore, this electromotor brake also has
There is the easy to operate and advantage of operation safety.
Although the foregoing describing detailed description of the invention of the present utility model, it will be appreciated by those of skill in the art that
This is merely illustrative of, and protection domain of the present utility model is defined by the appended claims.Those skilled in the art
