Embodiment
Embodiments of the present invention is further illustrated below in conjunction with accompanying drawing.
Referring to Fig. 1, disk 2 is solid extremely on high speed shaft 1; Urceolus 5 is arranged in the middle of two disks 2, and friction material 3 is set between the two; Urceolus 5 and high speed shaft 1 are concentric and separate, and urceolus 5 can rotate around high speed shaft 1 axle center; Two braking tiles 4 of block brake lay respectively at the both sides of urceolus 5.
Among Fig. 2, two inner cores 6,8 are arranged on the inside of urceolus 5, and are placed side by side; Two inner cores 6,8 and high speed shaft 1 be concentric to be provided with and to separate, and can rotate around high speed shaft 1 axle center; Between two inner cores 6,8 and the positioning block 10 that two ends band friction material 3 all is set between inner core 6,8 and the urceolus 5; Be connected with left side spiral spring 7 between left side inner core 6 and the urceolus 5; Be connected with right side spiral spring 9 between right side inner core 8 and the urceolus 5, bolt can be used in the joint.
Among Fig. 3, left side friction type ratchet 11 is set between high speed shaft 1 and the left side inner core 6, the rolling-in direction of left side spiral spring 7 is identical with the stuck action direction of left side friction type ratchet 11.
Among Fig. 4, right side friction type ratchet 12 is set between high speed shaft 1 and the right side inner core 8, the rolling-in direction of right side spiral spring 9 is identical with the stuck action direction of right side friction type ratchet 12.
When mechanism's normal operation, with mechanism's right lateral is example, the braking tile fragment 4 of block brake does not contact with urceolus 5, two inner cores 6,8 and urceolus 5 are because the effect of positioning block 10 is limited on the high speed shaft 1 and along with high speed shaft 1 clockwise rotates, at this moment, do not have relative rotation speed poor between urceolus 5 and the inner core 6,8, two spiral springs 7,9 are all inoperative.
When needs were braked, control brake tile fragment 4 made it to contact and hold tightly urceolus 5 with urceolus 5, causes urceolus 5 not change.Left side inner core 6 causes left side spiral spring 7 stressed because the effect of left side friction type ratchet 11 turns clockwise with high speed shaft 1, and left side inner core 6 produces speed discrepancies with urceolus 5, and in a clockwise direction rolling-in on left side inner core 6.Meanwhile, because right side friction type ratchet 12 does not play stuck effect, cause right side inner core 8 to skid on high speed shaft 1, right side inner core 8 does not have relative rotation speed poor with urceolus 5, and left side spiral spring 7 is inoperative.
In the process of left side spiral spring 7 rolling-in, urceolus 5 consumes portion of energy with disk 2 by friction material 3.
When causing high speed shaft 1, left side spiral spring 7 effect stops operating after (i.e. braking is finished), the take-off the brake tile fragment 4 immediately, urceolus 5 is because the retraction distortion of left side spiral spring 7 and clockwise rotating rapidly, meanwhile, right side spiral spring 9 promptly begins rolling-in, and urceolus 5 promptly rotates back and forth under the effect of two springs, in this rotary course, urceolus 5 contacts with friction material 3 all the time, and is final by rubbing energy consumption.
The plugging reason is identical.
