Abstract
The utility model relates to a winch barrel clutch driving structure which comprises a support, wherein a friction tape bended into a ring shape is arranged on the periphery of the support, the left end of the friction tape is fixedly connected with the support, and the right end of the friction tape is connected with a driving mechanism. The winch barrel clutch driving structure is characterized in that the driving mechanism is a lever-type driving mechanism and comprises a lever, the middle of the lever is hinged with the support, a clutch cylinder and a return spring are arranged between the lower end of the lever and the support, and the upper end of the lever is connected with the right end of the friction tape. The clutch cylinder drives the friction tape through the lever structure, pressing force can be magnified, static friction force between the friction tape and a coiling block friction ring is improved, so that slipping is avoided.
Description
Technical field
The utility model relates to a kind of capstan drum power-transfer clutch, particularly a kind of capstan drum power-transfer clutch drive configuration.
Background technology
Winch mainly applies to build, the material of hydraulic engineering, forestry, mine, harbour etc. goes up and down or flat dragging.Its power-transfer clutch is used to connect, cut off the moment of torsion transmission between reel and the driver train, and traditional capstan drum power-transfer clutch adopts the taper sheath friction clutch, compresses inner conical surface through male cone (strobilus masculinus) and realizes the moment of torsion transmission; The shortcoming of this kind structure is: mainly adopt M/C, there also have part to adopt to be pneumatic, cylinder along drum shaft to setting; And being located at the outside of frame, size is big, and is not attractive in appearance; And requiring has bigger thrust, and cylinder is had higher requirement, and certain potential safety hazard is arranged.
Summary of the invention
The technical matters that the utility model will solve provides a kind of effective capstan drum power-transfer clutch drive configuration that combines.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of capstan drum power-transfer clutch drive configuration comprises support; The support outer periphery is equipped with the friction band that bends to annular; The left end of friction band is connected fixing with support, friction band right-hand member connects driver train, and its innovative point is: said driver train is the lever driver train; It comprises a lever; This lever middle part is hinged with support, and clutch cylinder and retracing spring are set between lever lower end and the support, and the lever upper end is connected with friction band right-hand member.
The advantage of the utility model is: the clutch cylinder drives the friction band through lever construction, scalable thrust, and the static friction force with the reel friction ring is with in the raising friction, avoids skidding.
Description of drawings
Fig. 1 is the utility model capstan drum power-transfer clutch drive configuration scheme drawing.
The specific embodiment
As shown in Figure 1, comprise support 1, support 1 outer periphery is equipped with the friction that bends to annular and is with 2, and friction is connected fixing with support 1 with 2 left end, rub and be with 2 right-hand members connection driver train.Driver train is the lever driver train in the present embodiment, and it comprises a lever 3, and these lever 3 middle parts and support 1 are hinged, and clutch cylinder 4 and retracing spring 5 are set between lever 3 lower ends and the support 1, and lever 3 upper ends are with 2 right-hand members to be connected with friction.
Disengaged position: under the effect of retracing spring 5, lever 4 drawing friction bands 2 shrink, and make friction be with 2 outside faces to leave reel friction ring 6 inwall certain clearance;
Bonding state: the lower end that clutch cylinder 4 promotes lever 3 is around the hinge-point clickwise; Make the upper end cw promotion friction of lever 3 be with 2; Feasible friction is pressed on its peripheral reel friction ring 6 inside faces with 2; Lever construction can improve the static friction force of friction band and reel friction ring, avoids skidding.
