Specific embodiment
The utility model is further elaborated below by way of specific embodiment:
It as figure 1 shows a kind of brake disc handle release mechanism, have and be fixed by bolts in what motor rear end covered
Brake rear cover, to constitute an enclosure space between brake rear cover and back end cover for motor, motor shaft is rotatable
It is protruded into the enclosure space through back end cover for motor, the spindle nose of motor shaft is equipped with brake disc 200, and back end cover for motor is in face of braking
Friction plate 100 is installed, brake disc 200 is fixed on the interior of brake rear cover by main spring 800 on one side end face of disk 200
On end face, the pressing friction piece 100 under the elastic force effect of main spring 800 of brake disc 200 plays braking effect.
Brake disc 200 is equipped with electromagnet 300 relative to the side of back end cover for motor, ties up between electromagnet 300 and brake disc 200
Hold at regular intervals, brake disc 200 is irony, after electromagnet 300 is powered, generates electromagnetic force and overcomes the elastic force of main spring 800
Brake disc 200 is picked up, brake disc 200 is made to be detached from the friction plate 100 for being located at its other end, releases braking effect.
In order to smoothly overcoming 800 elastic force of main spring to pick up brake disc 200, need to be arranged multiple electromagnet 300, and
To install the suction to keep in balance in the form of annular array around main spring 800, in the utility model, electromagnet 300 is adopted
With two, it is mounted on main spring 800 at for the relative position in axle center.
Electromagnet 300 is equipped with cavity in face of a side end face of brake disc 200, and secondary spring 400, auxiliary are equipped in cavity
Spring 400 is pressed on 200 end face of brake disc, in this way brake disc 200 after a period of use, friction plate 100 can wear one
Section distance, and in this way dual spring mechanism still can tracing compensation these abrasion gap, it is ensured that the reliable braking of motor, thus
The braking moment for frequently adjusting motor is not needed.
Bolt 700 is connected on electromagnet 300, bolt 700 is connected by bindiny mechanism with brake disc 200, and bolt 700 is total
Two, be that axle center is put by relative position with main spring 800, bolt 700 be pierced by after brake rear cover with two of knob 500 it is solid
Fixed point connects, and lifts bolt 700 by knob 500, is raised brake disc 200 far from friction plate 100, plays solution in the short time
Except the effect of braking.
As shown in Fig. 2, bolt 700 is from head, portion is successively arranged flat tenon 701, the first cylinder to the structure of the bolt 700 on earth
Body portion 702, the first threaded portion 703, the second cylindrical body portion 704 and the second threaded portion 405, the second threaded portion 405 are tightened in electromagnetism
On iron 300, the first threaded portion 703 is connect with the fixed point spiral of knob 500.Brake rear cover is run through in first cylindrical body portion 702.
As shown in Fig. 2, it is socketed with nut 600 in the second cylindrical body portion 704, it, will when needing to release braking in for a long time
Nut 600 is screwed into the first threaded portion 703, then flat tenon 701 is fixed with spanner, reuse it is another spanner by nut 600 not
Disconnected is screwed into the first threaded portion 703, and bolt 700 is moved out in the effect that nut 600 is screwed into lifts separate rub for brake disc 200
Pad 100 plays the role of being braked for a long time.
When bolt 700 leaves unused on ordinary days, screw thread is socketed in the second cylindrical body between flat tenon 701 and the second threaded portion 405
In portion 704, bolt 700 can be prevented when motor works because vibration causes to loosen landing from bolt 700 using the design.
To sum up, using 200 handle release mechanism of the brake disc of the utility model, structure is simple, and space hold is small, and can have
Being released in short-term in the case where motor power loss for effect releases braking when braking and is long.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Utility model, and being not used as the restriction to the utility model, if in the spirit of the utility model, to
Variation, the modification of the upper embodiment will all be fallen in the Claims scope of the utility model.
