Abstract
The utility model provides a kind of miniature torque electromagnetic brake, comprises stator, armature, brake disc, spring, hollow screw, electromagnetic coil, pressure regulating ring, is provided with torsion amplifying device between armature and brake disc; Torsion amplifying device comprises taper pin and grabs, and taper pin is grabbed and is arranged on armature towards brake disc side, and brake disc is provided with the conical indents of grabbing with taper pin and engaging towards armature side; Torsion amplifying device can also be the VXing Mian mechanism of the flank of tooth mechanism of engagement, engagement, drive splines engaging mechanism.This electromagnetic brake can meet the place demand that some small spaces require larger braking torque, applies this electromagnetic brake and can reduce system cost, improve systematic function.
Description
Technical field
The utility model relates to a kind of break, is specifically related to a kind of electromagnetic brake, belongs to electromagnetic brake technical field.
Background technique
At present, although electromagnetic brake is not quite similar on mechanism principle, but generally there is mechanism's complexity, braking moment is little, and it is serious in its volume size constraint, therefore, be unfavorable for the problem solving small space, high-torque braking, be especially unsuitable in space flight, aviation field application, need a kind of volume little, the miniature high pulling torque break that braking moment is large for this reason.
Summary of the invention
In order to solve Problems existing in background technique, the utility model provides the electromagnetic brake that a kind of structure is simple, volume is little, braking moment is large, this electromagnetic brake can meet the place demand that some small spaces require larger braking torque, applies this electromagnetic brake and can reduce system cost, improve systematic function.
Concrete technical solution of the present utility model is:
A kind of miniature torque electromagnetic brake, comprises stator, armature, brake disc, spring, hollow screw, electromagnetic coil, pressure regulating ring, is provided with torsion amplifying device between described armature and brake disc.
Above-mentioned torsion amplifying device comprises taper pin and grabs, and described taper pin is grabbed and is arranged on armature towards brake disc side, and brake disc is provided with the conical indents of grabbing with taper pin and engaging towards armature side.
Above-mentioned torsion amplifying device can also be the VXing Mian mechanism of the flank of tooth mechanism of engagement, engagement, drive splines engaging mechanism.
The utility model has the advantage of:
As can be seen from structural principle of the present invention, it has the advantage that structure is simple, volume is little, reliability is high, braking torque is large, meet the place demand that some small spaces require larger braking torque, arrive the object reducing system cost, improve systematic function, especially can solve seaworthiness sky, the small space of aviation field, high pulling torque braking problem.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the magnification factor C of moment and the graph of a relation of angle of taper.
Accompanying drawing is detailed as follows:
1-stator; 2-armature; 3-brake disc; 4-spring; 5-hollow screw; 6-electromagnetic coil; 7-pressure regulating ring; 8-taper pin is grabbed.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail, as shown in Figure 1:
This miniature torque electromagnetic brake comprises stator 1, armature 2, brake disc 3, spring 4, hollow screw 5, electromagnetic coil 6, pressure regulating ring 7, stator 1 side is provided with pressure regulating ring 7, stator 1 opposite side is provided with armature 2, the protruding one end of pressure regulating ring 7 is inserted in stator 1 center hole, stator 1 is also provided with spring eye, spring 4 is held out against by spring eye one end and pressure regulating ring raised epitaxial, the other end armature 2 end face tightening; Electromagnetic coil 6 is also provided with in stator 1; In order to increase torsion, be provided with torsion amplifying device; The program is provided with taper pin at armature towards brake disc side and grabs, and brake disc is provided with towards armature side and grabs 8 conical indents engaged with taper pin; Torsion amplifying device can also be the VXing Mian mechanism of the flank of tooth mechanism of engagement, mating engagement, drive splines engaging mechanism.
When not powering up; under the pressure effect of spring 4; armature 2 engages with brake disc 3; reach the object of braking; in time powering up; under the suction of electromagnetic coil 6; armature 2 engages with brake disc throws off; reach and brake the effect of unclamping, due to taper pin grab 8 with the engaging of conical indents, make it improve 4-10 times than the braking torque of same volume conventional brake; compare conventional brake and save friction component again; by pressure regulating ring, with the addition of torque adjustment function, there is high pulling torque, adapt to feature that is wide, overload protection.Ultimately provide the electromagnetic brake that a kind of structure is simple, braking torque is large, volume is little, function is many.
During armature power-off, provide pressure by spring 4, make taper pin grab 8 and mesh together with the conical indents on brake disc 3, braking moment is provided, moment size is relevant with spring pressure and shrinkage pool angle of taper, and during armature energising, taper pin is grabbed 8 with conical indents and thrown off, braking moment disappearance.Moment is directly proportional to the initial pressure of spring, the magnification factor C of moment and the relation of angle of taper are as shown in Figure 2, as shown in Figure 2, when spring pressure is constant, cone angle is getting in 40 ° of-20 ° of intervals, and torsion can amplify 4-10 doubly, and this feature is different from traditional break, its moment is only relevant with pressure and friction factor, and power gain (friction factor) is generally not more than 2.
