Abstract
The present invention relates to a kind of coupling overload protection structure, specifically a kind of structure being suitable for protecting flexible coupling part when torque overload belongs to shaft coupling technical field.It includes Coupling Shaft, flexible element and transfer panel, and Coupling Shaft one end is equipped with carrying flange, and transfer panel one end is equipped with appearance profile and the carrying mutually isostructural carrying counterbore of flange, and the carrying flange of Coupling Shaft stretches into the carrying counterbore of transfer panel；Transfer panel side is equipped with flexible element, and flexible element is fastened on by multiple connectors on transfer panel and carrying flange.The present invention utilizes the rigid attachment structure of counterbore and flange, and a part of load can be undertaken when shaft coupling overloads, avoids the damage of flexible element；Driving, effective protection unit miscellaneous equipment are avoided when flexible element fails simultaneously.
Description
Technical field
The present invention relates to a kind of coupling overload protection structures, specifically a kind of to be suitable for protection connection when torque overload
The structure of axis device flexible element, belongs to shaft coupling technical field.
Background technology
General flexible coupling is easy to cause permanent damage to flexible element, in turn when unit carrying is excessive
Influence the service life of shaft coupling.When unit torque overload is more than a certain range, flexible element failure is possible to occur at this time
The case where driving and unit other equipment is damaged.
Invention content
It is an object of the present invention to overcome the above deficiencies, can to provide a kind of coupling overload protection structure
A part of load is undertaken when shaft coupling overloads, and avoids the damage of flexible element；Driving is avoided when flexible element fails simultaneously, effectively
Protect unit miscellaneous equipment.
According to technical solution provided by the invention, a kind of coupling overload protection structure includes Coupling Shaft, flexible element and turns
Disk is connect, it is characterized in that：Coupling Shaft one end is equipped with carrying flange, and transfer panel one end is equipped with appearance profile structure identical as carrying flange
Carrying counterbore, the carrying flange of Coupling Shaft stretches into the carrying counterbore of transfer panel；Transfer panel side is equipped with flexible element, flexible element
It is fastened on transfer panel and carrying flange by multiple connectors.
Further, there are certain gaps between carrying flange and carrying counterbore.
Further, carrying flange is polygonized structure.
Further, multiple connectors are cross-linked on carrying flange and transfer panel.
Compared with the prior art the present invention has the following advantages：
The invention has the advantages of simple structure, compactness and reasonable structure, can be when shaft coupling overloads using the rigid attachment structure of counterbore and flange
A part of load is undertaken, the damage of flexible element is avoided；Driving is avoided when flexible element fails simultaneously, effective protection unit is other to be set
It is standby.

Fig. 2 is C-C sectional views in Fig. 1.
Reference sign：1- Coupling Shafts, 2- flexible elements, 3- transfer panels, 4- connectors, 5- carryings flange, 6- carryings are heavy
Hole.
Specific implementation mode
The present invention will be further described in conjunction with the embodiment in attached drawing below：
As shown in Figure 1 and 2, the invention mainly comprises Coupling Shaft 1, flexible element 2 and transfer panel 3,1 one end of Coupling Shaft is equipped with carrying method
Orchid 5,3 one end of transfer panel are equipped with appearance profile and carrying 5 mutually isostructural carrying counterbore 6 of flange, the carrying flange 5 of Coupling Shaft 1
It stretches into the carrying counterbore 6 of transfer panel 3.
There are certain gaps between the carrying flange 5 and carrying counterbore 6.
In embodiment as shown in Figure 2, the carrying flange 5 is polygonized structure.In another embodiment, can also
Set every straight flange for carrying flange 5 to arc-shaped edges.
3 side of transfer panel is equipped with flexible element 2, and flexible element 2 is fastened on transfer panel 3 and carrying flange 5 by multiple connectors 4
On.
In embodiment as shown in Figure 2, the multiple connector 4 is cross-linked on carrying flange 5 and transfer panel 3.
The present invention operation principle be：Flexible member is cross-linked by multiple connectors in carrying flange and transfer panel
On, to which torque is transmitted to transfer panel from Coupling Shaft, under the normal load situation that flexible member can be born, Coupling Shaft is held
Carry flange and the carrying counterbore in Coupling Shaft has certain gap between each other, once the load that flexible member is born is beyond specified
Range, Coupling Shaft start to contact with the flange side of transfer panel, so as to reduce the load born on flexible member, reach guarantor
Protect the effect of flexible member.And when flexible member fails, carrying flange and carry counterbore rigid attachment can temporarily pass
Torque delivery can prevent driving with effective protection equipment.
The invention has the advantages of simple structure, compactness and reasonable structure, can be in shaft coupling mistake using the rigid attachment structure of counterbore and flange
A part of load is undertaken when load, avoids the damage of flexible element；Avoid driving when flexible element fails simultaneously, effective protection unit its
Its equipment.
