Abstract
The utility model discloses a kind of torque limiter of driving chain of wind generating set; including multiple force moment protection units; each force moment protection unit is made up of a shear pin and a flexible piece; the shear pin is fixed on generator shaft; and linked together by flexible piece with shaft coupling; the shaft coupling is connected with gearbox output shaft, and the shear pin in all force moment protection units bears torque, and direction and the central axis of shear pin of torque jointly.It is engaged by shear pin with flexible piece so that shear-type load is equably carried on each shear pin, it is ensured that the reliability of force moment protection, while changing easy.If without this load balancing structure, because the load born on the error of assembling, each shear pin is inconsistent, it will make it that Partial Shear pin is cut by excessive shearing force, easily when the situation that torque is not reaching to design load and cut, influence wind power generating set is normally run.
Description
Technical field
The utility model is related to the technical field of driving chain of wind generating set force moment protection, refers in particular to a kind of wind-force hair
The torque limiter of group of motors driving-chain.
Background technology
Known in the industry, the torque limiter of existing driving chain of wind generating set is typically to use friction pair form,
Volume and weight is larger, and the demand of the compact design increasingly increased with wind power generating set is runed counter to, while when the torque on blower fan
Protection device changes extremely difficult after damaging.
It may be such that volume and weight is all mitigated by the way of shear pin, cost is low, in wind power generating set more
Change easily.It is well known that the structural shape of single shear pin has been obtained for being widely applied, but multiple shear pins can be present
The uneven situation of shear stress that single shear pin pin is born, the protection torque resulted in the need for can not be met.
The content of the invention
The purpose of this utility model be to overcome the deficiencies in the prior art there is provided one kind it is simple and reliable for structure, lightweight, into
The torque limiter of easy driving chain of wind generating set is changed on this low, blower fan.
To achieve the above object, technical scheme provided by the utility model is：A kind of driving chain of wind generating set
Torque limiter, including multiple force moment protection units, each force moment protection unit is by a shear pin and a flexible piece group
Into the shear pin is fixed on the generator shaft of driving chain of wind generating set, and passes through flexible piece and wind power generating set
The shaft coupling of driving-chain links together, the gearbox output shaft connection of the shaft coupling and driving chain of wind generating set, institute
Shear pin in moment protection location bears torque, and direction and the central axis of shear pin of torque jointly.
The flexible piece is that the shear pin is cased with rubber parts on rubber parts, the external cylindrical surface for being enclosed on shear pin one end
One end be embedded in shaft coupling, its other end is fixed on generator shaft, by the flexible piece torque can be caused uniformly to add
It is downloaded on each shear pin, while offset electricity generation arbor and gearbox output shaft can also misalign to a certain extent.
The utility model compared with prior art, has the following advantages that and beneficial effect：
It is engaged by shear pin with flexible piece so that shear-type load is equably carried on each shear pin, it is ensured that
The reliability of force moment protection, while changing easy.If without this load balancing structure, because the error of assembling, each shear pin
On the load born it is inconsistent, will make it that Partial Shear pin is cut by excessive shearing force, easily when torque is not reaching to
Design load and situation about being cut, influence wind power generating set are normally run.
Brief description of the drawings
Fig. 1 is the scheme of installation of the single force moment protection unit of the utility model torque limiter.
Embodiment
With reference to specific embodiment, the utility model is described in further detail.
As shown in figure 1, the torque limiter of the driving chain of wind generating set described in the present embodiment, including multiple torques
Protection location, each force moment protection unit is made up of a shear pin 1 and a flexible piece 2, and the shear pin 1 is fixed on wind-force
On the generator shaft 3 of generating set driving-chain, and it is connected to by the shaft coupling 4 of flexible piece 2 and driving chain of wind generating set
Together, the shaft coupling 4 is connected with the gearbox output shaft 5 of driving chain of wind generating set, and such power transfer path is
Gearbox output shaft 5, shaft coupling 4, flexible piece 2, shear pin 1, generator shaft 3；Shear pin 1 in all force moment protection units is total to
It is same to bear torque, and direction and the central axis of shear pin 1 of torque.Wherein, the flexible piece 2 is rubber parts, is to be enclosed on
On the external cylindrical surface of the one end of shear pin 1, the shear pin 1, which is cased with one end of rubber parts, to be embedded in shaft coupling 4, and its is another
End is fixed on generator shaft 3.In the present embodiment, flexible piece 2 serves two effects：One is torque uniform load to each
In shear pin 1 so that shear protective function is reliable, when the torque of transmission exceedes setting value, shear pin 1 can be cut off, so that
Protect driving-chain；Two be to allow two the small of axle to misalign, you can offset electricity generation arbor 3 and gear-box are defeated to a certain extent
Shaft 5 is misaligned.
Examples of implementation described above are only the preferred embodiment of the utility model, not limit of the present utility model with this
Practical range, therefore the change that all shape, principles according to the utility model are made, all should cover in protection domain of the present utility model
It is interior.
