Brief description of the drawings
Fig. 1 be the utility model it is a kind of can electrodeless control braking torque electricity loss brake schematic diagram.Fig. 2 is this reality
With the graph of a relation of new coil current and braking torque.
Embodiment
With reference to Fig. 1 and Fig. 2, specific embodiment of the utility model is described further.
As shown in figure 1, electricity loss brake is made up of fixed part and movable part.
Wherein fixed part is connected with equipment supporter, is made up of yoke 1, coil 2, set 3, clamping plate 4 and bolt 5.Set 3 is located at
Between clamping plate 4 and yoke 1, clamping plate 4 is separated with yoke 1 with set 3, is locked yoke 1 and clamping plate 4 by bolt 5, coil 2 is set
In yoke 1.
Movable part is made up of among fixed part spline housing 6, frictional disk 7, armature 8, spring 9.Frictional disk 7 with
The cooperation of spline housing 6, frictional disk 7 are connected by six groove splines with spline housing 6, are axially movable.In the internal diameter of spline housing 6, it is provided with
There is keyway, keyway is used for the axis connection of the motion with needing to brake.
Armature 8 is loaded between frictional disk 7 and yoke 1, and can be moved axially in the range of air gap delta, the side pressure of spring 9 one
In yoke 1, other end connection armature 8.
When under rated voltage, coil current produces magnetic field between yoke 1 and armature 8, suction moving armature 8 moves to yoke 1,
Armature 8 leaves frictional disk 7, does not produce braking torque, and frictional disk 7 can rotate with spline housing 6, and now equipment is in normal work
State.
In the case of electricity, in the presence of spring 9, armature 8 presses to frictional disk 7, and caused normal pressure is produced by frictional disk 7
Raw about 100Nm braking torque.Movement parts are made progressively to stop in the presence of the moment of torsion.
It is the curve map of electric current and braking torque relation as shown in Figure 2, in the presence of controller, control coil electric current,
Magnetic field intensity can be adjusted, you can control the size of braking torque, make braking torque stepless control in certain scope.Electric current
For 0 when, braking torque 110Nm, with the increase of electric current, braking torque is gradually reduced, when electric current is 0.75A, braking turn round
Square is 0.
