Description
Technical field
The present invention relates to aerostatics lift-off to reclaim, be specifically related to a kind of cable winch reel reclaimed for aerostatics lift-off.
Background technology
at present, a kind of cable winch reel structure is the many rope groove drums hawser towing capstan being mainly used in hawser folding and unfolding capstan winch, cable drawing machine or deep-sea expedition winch iso-deflection frottage transmission.The reel structure of general hawser towing capstan, its grooving for flexible frictional transmission and reel are an entirety, and grooving and reel move as rigid element integral-rotation, and the velocity of rotation of each grooving of reel is synchronous.If the hawser in grooving does not cause Elastic Sliding because of the elastic elongation distortion produced during tension, and the linear velocity of each groove hawser will be consistent with the linear velocity of grooving (or reel).But actual conditions are really not so, especially because of hawser motion more complicated caused under the combined action of friction force, centripetal force and various external force.
Belt Drive is most typical flexible frictional transmission.People are found by theoretical analysis and practice: Belt Drive is except overall failure mode situation, also have a kind of usually by situation---Elastic Sliding that people ignore, its basic reason produced is exactly the elastic deformation of flat rubber belting, will there will be skidding when flat rubber belting extends or shrinks when the internal force produced is greater than the friction force that flat rubber belting and mating surfaces produce.Because the pulling force usually entering and leave power wheel two ends in the process of flat rubber belting transmitting force is unequal, the elastic deformation amount that flat rubber belting was entering and leaving power wheel two ends is also just different; And the tension force in effective friction cornerite of flat rubber belting on power wheel gradually changes, the elastic deformation amount in effective friction cornerite of flat rubber belting on power wheel is also just different.Therefore, the elastic deformation in fact produced during hawser tension, makes the linear velocity of hawser can not remain consistent with the linear velocity of grooving.Different from the friction cornerite of Belt Drive, the hawser friction cornerite of many rope groove drums hawser towing capstan is generally not less than 5 π, larger than the friction cornerite in Belt Drive more than 3 times.The gap that reel enters between rope and the cable tension of rope-out end is large, and cable length change also more greatly, causes the possibility of hawser micro-slip larger.Theoretical analysis is thought, Elastic Sliding always occurs in flat rubber belting and leaves on that section of arc of contact of belt wheel.Because its elastic deformation hawser that the hawser finally leaving spool portion enters reel relatively is at first with the biggest gap, and this part cable tension is relatively little, corresponding flexible friction drag is also less, and the possibility that shrink the effect of restoring force at hawser under, (i.e. turnover hawser two ends tension force difference) hawser generation is skidded is also maximum.The conclusion that can draw is: the hawser hawser left in last grooving of reel is the most easily in a kind of state of relative sliding usually, its extreme performance is exactly the situation that hawser produces skidding in this grooving, and ideally only produces Elastic Sliding.The result brought of skidding under large load condition is the hawser protection sharp wear of epidermis and the load impacting of hawser load-carrying member, crossing skids frequently can also produce frictional heat phenomenon, make hawser skin temperature too high, these all can reduce the service life of hawser, actual use also shows, the slip of large load condition is impacted and easily caused hawser cuticular breakdown.
Summary of the invention
Object of the present invention is exactly for above-mentioned deficiency, and provides a kind of cable winch reel reclaimed for aerostatics lift-off.
The present invention includes reel, friction ring and a pair annular shoulder block, reel has annular friction groove, friction ring is arranged in the annular friction groove on reel, and a pair annular shoulder block is arranged on reel both sides respectively by nut.
Friction ring is made up of one or more friction ring.
Reel and a pair annular shoulder block are one.
Advantage of the present invention is: simple and practical, can ensure the construction profile of conventional reel, can ensure again the tractive property of conventional reel, installs and changes part maintenance conveniently; Dermal abrasion and the load impacting of hawser can be reduced under large load condition, extend the service life of hawser.

Detailed description of the invention
As shown in Figure 1, 2, 3, the present invention includes reel (1), friction ring (2) and a pair annular shoulder block (3), (1) has annular friction groove with reel, friction ring (2) is arranged in the annular friction groove on reel (1), and a pair annular shoulder block (3) is arranged on reel (1) both sides respectively by nut.
Friction ring 2 is made up of one or more friction ring.
Reel 1 and a pair annular shoulder block 3 are one.
Occupation mode: at least 1 friction ring (2) is installed on that one end that hawser leaves reel.If capstan winch is used for bivector traction (or the folding and unfolding of band load) hawser, 1 friction ring (2) is all set at the two ends of reel.1 friction ring (2) can be increased in that one end that cable tension is less.In the outside of friction ring (2), shoulder block (3) is installed, prevents friction ring (2) from skidding off rigidity reel (1) outward along friction face, also in the upper installation of rigidity reel (1) or the frictional groove preventing friction ring (2) from skidding off can be processed.
With friction ring (2), shoulder block (3) and friction (groove) face that contacts with friction ring (2) on cable winch reel.The material selected due to friction ring (2) and rigidity reel (1) effective friction coefficient rubbed between (groove) face are less than the effective friction coefficient between hawser and friction ring (2) grooving, when hawser because of the grooving of the factors such as elastic deformation on residing friction ring close to critical slipping state before, friction ring (2) just and produce between friction (groove) face of rigidity reel (1) and skid, and balances the cable tension at these friction ring two ends immediately.Like this, in grooving, producing the problems such as skidding with regard to solving hawser, reducing the dermal abrasion and load impacting etc. of hawser in grooving.
The tractive force of hawser is jointly transmitted by flexible fricting transmissioning mode by the grooving on the grooving on rigidity reel (1) and friction ring (2), and friction ring (2) is positioned at that one end that its hawser drawn leaves reel.When capstan winch bivector traction (or the folding and unfolding of band load) hawser, friction ring (2) is positioned at the two ends of reel.That one end that hawser leaves reel at least arranges 1 friction ring (2), and hawser is can arrange 2 friction rings (2) when comparatively small tension receiving coil leaves reel.
Owing to should ensure that friction ring (2) skids prior to hawser, ensure that friction ring (2) can also transmit certain friction force again, the upper effective friction coefficient rubbed between (groove) face of friction ring (2) and rigidity reel (1) should ensure it is 0.8 times ~ 1.0 times of the effective friction coefficient between institute's pull-cord and friction ring (2) grooving.Otherwise, or do not have the effect of available protecting hawser, or do not have the effect of effectively transmitting friction force.Select the good material of resistance to abrasion can improve the service life of friction ring (2).
