Fig. 2 is the structural representation of the present invention under the braking separated state.
Embodiment
Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
Like Fig. 1, shown in 2; The present invention includes housing 7, flange 2 is installed in an end of housing 7 through screw, and driving shaft 1 is through bearing 3 rotatable being installed on the flange 2; Driven shaft 14 is through bearing 15 rotatable being installed on the housing 7, and driving shaft 1 is coaxial with driven shaft 14.Initiatively friction disk 4 usefulness flat keys 101 and screw are installed on the driving shaft 1; Driven friction disk 12 endoporus are provided with keyway; Driven shaft 14 is provided with flat key 8, and driven friction disk 12 flip sleeves are contained on the driven shaft 14 and (are Spielpassung between driven friction disk 12 and the driven shaft 14), through flat key 8 transmitting torques; Initiatively friction disk 4 constitutes the gearing friction pair with driven friction disk 12; In the present embodiment, asbestos-free friction sheet 401 is riveted on the initiatively front end of friction disk 4, and asbestos-free friction sheet 401 can make active friction disk 4 big with driven friction disk 12 transmitting torques; Wear-resisting, and impact from, fashionable nothing.Yoke 5 is ring, and yoke 5 is sleeved on outside the driving shaft 1 and through screw and is installed on the flange 2, is provided with field coil 6 in the yoke 5.Armature 10 is disc; Armature 10 is installed on the driven friction disk 12 through bearing 11; Braking plate 13 is fixedly mounted on the rear end of driven friction disk 12 through screw thread; On driven friction disk 12, make axial restraint for armature 10 and bearing 11 simultaneously, can see thus, braking plate 13, bearing 11 and armature 10 can be accompanyed or follow kinetic friction dish 12 and on driven shaft 14, slide together.6 extension springs 9 are uniformly distributed with at the circumferencial direction of armature 10, and an end of extension spring 9 is fixedly connected armature 10, and the other end of extension spring 9 is fixedly connected housing 7, need usually at least 3 extension springs 9 are set, and the quantity of extension spring 9 can be confirmed according to actual needs.Brake disc 16 is installed on the housing 7 through screw; Braking plate 13 constitutes brake friction pair with brake disc 16; Brake disc 16 is made up of at the front end of substrate asbestos-free friction sheet 1601 sintering, and asbestos-free friction sheet 1601 can reduce to impact when braking, and wear-resisting.Armature 10 is held in equally distributed 6 extension springs 9, and the pulling force of extension spring 9 is pulled together braking plate 13 and brake disc 16, thereby makes driven shaft 14 be in braking state.
The present invention in use, driving shaft 1 can connect the output shaft of motor through shaft coupling, perhaps motor output shaft is directly connected initiatively friction disk 4 as driving shaft.
See Fig. 1, when field coil 6 is not switched on, because armature 10 is held in extension spring 9; Braking plate 13 is pulled together with brake disc 16, is in braking state, and the driven shaft 14 that links with braking plate 13 can not rotate; And initiatively friction disk 4 is in disengaged position with driven friction disk 12, driving shaft 1 idle running.
See Fig. 2; After field coil 6 energisings; The electromagnetic force of field coil 6 overcomes the pulling force of extension spring 9, attracts armature 10 to drive driven friction disk 12 relative driven shafts 14 to lower slider, and driven friction disk 12 and active friction disk 4 are engaged; Braking plate 13 and brake disc were opened in 16 minutes; Driven shaft 14 breaks away from braking state and is driven with fast, rotation in the same way by driving shaft 1, and driven shaft 14 drives equipment operation, and the electromagnetic force that field coil 6 electric currents produce makes driven friction disk 12 and active friction disk 4 keep jointing states.Because be provided with bearing 11 between armature 10 and the driven friction disk 12, armature 10 does not rotate.
See Fig. 1, after field coil 6 dead electricity, because the pulling force of extension spring 9; Pulling armature 10 drives driven friction disk 12 relative driven shafts 14 and upwards slides, and makes driven friction disk 12 hightail initiatively friction disk 4, thus driving shaft 1 idle running; Braking plate 13 engages rapidly with brake disc 16 simultaneously; Make driven shaft 14 brakings that link with braking plate 13, driven shaft 14 stops operating rapidly, and can be owing to inertia is rotated further.
