Description
Technical field
The present invention relates to a kind of cable hank.
Background technology
DE 101 42 110 A1 disclose a kind of cable hank especially for dust catcher, and it has disk body and base plate, and disk body is with respect to the base plate rotatably support.A braking rocking bar radially is mobilizable with respect to base plate and some elastomeric elements is set.Cable hank is bearing in the housing that holds it by these elastomeric elements, particularly in the dust catcher.Provide a kind of cable hank according to this design, in this cable hank, be used for the elastomeric element that cable hank is bearing in housing reached the purpose that is directed on the housing is impacted in braking by use.Be rotatably supported on the supporting structure at this design mid-game core.The supporting of coiling core is there not only finished on the hub disk flange but also on the shroud flange with respect to the supporting structure of cable hank.This core that will coil is that variation owing to the axial length of the higher reason dish core of temperature can cause supporting overtension in the shortcoming of two-side supporting on supporting structure.In addition, it is also very high in the both sides of dish core the supporting cost to be set on supporting structure.Yet the supporting for the dish core always requires so stably to implement supporting, thereby when overload, can not occur the situation of damage dish core or supporting structure when for example clashing into.
Summary of the invention
Task of the present invention is the supporting of simplification dish core on supporting structure, and also reaches high security even so when the cable hank mechanical overload.
The invention provides a kind of cable hank that is installed in the electrical equipment; this electrical equipment has the housing parts of belt supporting frame; this support is used to hold the supporting structure that is arranged on the cable hank; rotating dish core at this supporting structure upper support; being supported of this dish core; and the first end towards supporting structure has the hub disk flange; and the second end of the supporting structure dorsad of this dish core has the shroud flange; wherein said shroud flange be non-supporting and have a stop mechanism; this stop mechanism is attached troops to a unit in corresponding stop mechanism; wherein said stop mechanism and corresponding stop mechanism are forming each interval distance under the situation in gap when cable hank is the normal mechanical service load; it is characterized in that; gap width has size; when cable hank because during the radial load generation strain that imported, stop mechanism contacted before cable hank reaches the mechanical load limit with corresponding stop mechanism.
According to the present invention, this task is finished by following measure, and promptly the shroud flange is that nothing supports and has stop mechanism, and this stop mechanism is attached troops to a unit in corresponding stop mechanism.Reach the dish core by this design by unique bearing and be bearing in fully on the supporting structure, wherein, what coil core keeps not having supporting with the opposed end of supporting, and free projection.Yet the end of the free projection of dish core sets stop mechanism, and this stop mechanism contacts with percussion device when overload.When the cable hank operate as normal, between stop mechanism and corresponding stop mechanism, keep small gap, thus the dish core in this position be do not have a supporting and this end without undergoing any frictional force.So design the gap size between stop mechanism and the corresponding stop mechanism, make when overload supporting structure or the distortion of this dish core remain in the flexible scope, supporting structure in this scope, can not occur or coil any infringement on the core.Distortion reach can cause permanent damaged condition before stop mechanism contact with corresponding stop mechanism, thereby just can not continue to take place the distortion of supporting structure or dish core.The overload power that is occurred then is transferred on the percussion device by stop mechanism.As long as cable hank is overload not, supporting structure coils core in other words and turns back to its original position.Stop mechanism and corresponding stop mechanism form with gap again and separate in this original position.Because what occurred when most overload situations is temporary transient bump overload, so stop mechanism is only very in short-term near corresponding stop mechanism, thereby on the contact site of stop mechanism and corresponding stop mechanism tangible abrasion can not appear, and particularly all not moving probably at the moment cable hank that bump stroke applies.
Stop mechanism and corresponding stop mechanism particularly bear the radial load that affacts cable hank.Stop mechanism can be that the cable hank with rotatably support is arranged on the baffle ring on the shroud flange with one heart, and this baffle ring has the radially stop surface towards corresponding stop mechanism.This organization plan of the stop mechanism by being designed to baffle ring can be by corresponding stop mechanism carrying-off radial load, and still is rotatably supported on the supporting structure with the hour indicator core.
In a kind of preferred design of the present invention, the radially stop surface of baffle ring has the little diameter of overall diameter than the dish flange.Because the diameter of baffle ring is littler than the overall diameter of ring flange, so the physical dimension of cable hank does not increase.In addition because the less diameter of baffle ring, near the movement velocity of the baffle ring of corresponding stop mechanism than have with the overall diameter that coils flange quite or to have a baffle ring of larger diameter little.Can prevent friction and wear between baffle ring and the corresponding stop mechanism by this measure.
The radially stop surface of baffle ring can be formed by the shroud flange in the axial direction protrudingly.This has following advantage, promptly the radially stop surface of baffle ring from the dish core that has supported towards the end of supporting structure distance farthest.Utilize maximum lever arm in this case, so that the radial load that occurs is delivered on the corresponding stop mechanism by baffle ring when overload.
Because the turnability of dish core, for the frictional force that makes wearing and tearing and braking keeps less, when the normal machine work load of cable hank stop mechanism and corresponding stop mechanism can be under the situation that forms the gap each interval distance.Like this when normal machine work condition the free projection of assurance dish core and dorsad the end of supporting structure keep not having supporting, and therefore be not subjected to affacting the braking effect of dish core.
Preferably gap width should have size, and when because the radial load cable hank of introducing when strain occurring, and stop mechanism contacts with corresponding stop mechanism before the load limitation that reaches machinery in this size.Certain gap width can be set, certain activity be arranged with the free end of permission dish core, and stop mechanism in other words baffle ring do not contact with collision block.For example only since manufacturing tolerance this requirement is just arranged, for example when baffle ring be not accurate circle or be not accurately with the dish core coaxial.Should allow baffle ring small off-centre to be arranged, but baffle ring does not contact when normal load again with corresponding stop mechanism with respect to rotating dish core.
In a kind of simple design of corresponding stop mechanism, this corresponding stop mechanism can be the rib of projection in housing parts, and this rib has and the suitable abutment surface of the radially stop surface of stop mechanism.When baffle ring was used as stop mechanism, the stop mechanism that is designed to the rib of projection had the edge of circular arc, and this edge contacts with the radially stop surface of stop mechanism when overload.Preferably the stop surface spacer of the abutment surface of corresponding stop mechanism and baffle ring is liftoff is provided with it with extending in parallel.By this design guarantee when overload stop surface contact with abutment surface as far as possible in large area, so just can will transship the power carrying-off by big as far as possible surface.Also stop mechanism that people worried and the wearing and tearing between the corresponding stop mechanism are dropped to minimum by the little compressive load per unit area that reached thus.
In a kind of flexible program of the present invention, corresponding stop mechanism is arranged on the housing parts of electrical equipment.Replace this flexible program, the supporting structure that also stop mechanism can be arranged on cable hank originally on one's body.Supporting structure has axle journal in this design, and this axle journal passes the dish core and stretches again on the end of the supporting structure dorsad that coils core, baffle ring ground supporting structure is designed to corresponding stop mechanism in other words perpendicular to stop mechanism there.Need to prove at this for the purpose of the prior art of quoting in order to be different from, this design is not to be the supporting of dish core both sides, because between the corresponding stop mechanism of baffle ring and supporting structure gap freely is being set in other words at stop mechanism on this end when normal operating conditions.Just be bearing in short time on this end of supporting structure, and do not form a supporting position at overload hour indicator core.
