Explain characteristics of the present utility model below in conjunction with concrete principle of work:
One, when motor 7 gets electric clockwise rotating, power is passed to brake coupling band 4 by transmission shaft 91, brake coupling band 4 at first drives first and reverses cover 31 rotations, make the outer brake cone dish 21 that is in Pre strained state originally, brake hubs 23, interior brake cone dish 22 unclamps, and torsion spring is owing to first reverse cover 31 and rotate and to be in the torsion enlarging state, reverse cover 31 when turning over the α angle when first, 4 drives first of brake coupling band are reversed cover 31 and second and are reversed synchronously rotation of cover 32, at this moment spiral engaging and disengaging gear 3 is inoperative, the second rotation of reversing cover 32 is passed to speed reduction gearing by brake axle 1, finally be passed to reel, and brake hubs 23 can be rotated together with reel.
Two, when motor 7 gets electric rotating counterclockwise, power is passed to brake coupling band 4 by transmission shaft 91, brake coupling band 4 at first drives second and reverses cover 32 rotations, reverse between the cover 32 as interacting because first reverses cover 31 and second, the second rotation of reversing cover 32 can make the outer brake cone dish 21 that is in Pre strained state originally equally, brake hubs 23, interior brake cone dish 22 unclamps, and torsion spring is because the first antagonistic force that reverses cover 31 is in the torsion enlarging state, reverse cover 32 when turning over the α angle when second, 4 drives first of brake coupling band are reversed cover 31 and second and are reversed synchronously rotation of cover 32, at this moment spiral engaging and disengaging gear 3 is inoperative, the second rotation of reversing cover 32 is passed to speed reduction gearing by brake axle 1, finally be passed to reel, and brake hubs 23 can be rotated together with reel.
Three, be not subjected in the situation of load force effect when motor 7 dead electricity and reel 6, all there is not transmission of power on brake axle 1 and the brake coupling band 4, and torsion spring motor 7 be in when electric and laid in larger torsion in the situation of the state of tightening, at this moment torsion spring discharges 3 actions of torsion driving spiral engaging and disengaging gear, makes pre-pressing between outer brake cone dish 21, brake hubs 23, the interior brake cone dish 22.
Four, when motor 7 dead electricity and reel 6 are subjected in the situation of load force effect, load band movable reel 6, reel 6 with transmission of power to speed reduction gearing 8, speed reduction gearing 8 drives brake axle 1 by transmission shaft 92 and rotates, brake axle 1 drives second and reverses cover 32 rotations, spiral engaging and disengaging gear 3 separates, because brake cone dish 21 at this moment, brake hubs 23, be in the pre-pressing state between the interior brake cone dish 22, under the effect of spiral engaging and disengaging gear 3, outer brake cone dish 21, brake hubs 23, more press tighter between the interior brake cone dish 22, brake hubs 23 brakings, because brake hubs 23 and the engagement of reel 6 key teeth, so reel 6 has also obtained effective brake.
In the above-mentioned principle, what first and second two states can be understood as capstan winch puts rope, rope closing state, and the third state can be understood as that capstan winch is put, the transition condition between rope closing state and the braking mode, the state when also can be understood as capstan winch and not working.
Embodiment two:
With reference to Fig. 5, the structure of present embodiment and embodiment one are roughly the same, and something in common no longer describes in detail, and different is: winch brake device also comprises outside friction disc 26 and the inner attrition piece 25 that is located between brake axle 1 axle head and the outer brake cone dish 21.Principle of work with reference to embodiment one, in the present embodiment capstan winch braking procedure, under the effect of spiral engaging and disengaging gear 3, more press tighter between outside friction disc 26, inner attrition piece 25, outer brake cone dish 21, brake hubs 23, the interior brake cone dish 22, brake hubs 23 brakings, because brake hubs 23 and the engagement of reel 6 key teeth, so reel 6 has also obtained effective brake; In addition, be provided with the key tooth in inner attrition piece 25 outer rings, inner attrition piece 25 meshes with reel 6 key teeth, plays the effect of auxiliary braking.In addition, braking outside is provided with belleville spring 27 between cone dish and brake axle 1 axle head, increases belleville spring 27 and comes balanced system power, so that braking is more steady, noise is little, reliability is high, and so that but each the parts axial float on the brake axle 1 is convenient to adjustment.The concrete principle of work of present embodiment can be with reference to embodiment one.
Embodiment three:
With reference to Fig. 6, the utility model winch brake device also can be done following simple transformation: interior brake cone dish 22 is become discoid, first reverses cover 31 coils 22 one-body molded with interior brake cone.But all the other structures of present embodiment winch brake device and principle of work reference example one thereof or embodiment two no longer describe in detail.
By above-described embodiment, the purpose of this utility model is by in full force and effect having reached.The personage who is familiar with this skill should be understood that the utility model includes but not limited to the content of describing in accompanying drawing and the top specific embodiment.Any modification that does not depart from function and structure principle of the present utility model all will be included in the scope of claims.
