According to the invention, by utilizing the characteristic that the length of the shoulder bushing body is larger than the thickness of the corresponding flange, the deformation allowing space is formed at the left side and the right side of the movable flange, so that the excessive deformation of the coupler can be effectively prevented, and the flexible piece is protected from being damaged.
Description
Technical Field
The invention relates to a flexible part protection structure, in particular to a protection structure for preventing a flexible part from being excessively deformed, and belongs to the technical field of flexible couplings.
Background
Couplings with externally positioned flexible members typically do not have a protective mechanism designed to limit excessive deformation of the flexible members, so there are instances where the coupling is damaged by an unexpected axial displacement of the unit that would cause the coupling to withstand beyond its designed deformation capability. After the coupler is damaged, the whole set of coupler may need to be replaced, and certain economic loss can be brought to the stop operation of the unit.
Disclosure of Invention
The invention aims to overcome the defects, thereby providing a protection structure for preventing the flexible part from being excessively deformed, ensuring the deformation of the flexible part of the flexible coupling to be in a designed deformation range, effectively preventing the flexible part of the flexible coupling from being damaged by the excessive deformation, improving the reliability of the flexible coupling and prolonging the service life of the flexible coupling.
According to the technical scheme provided by the invention, the protection structure for preventing the flexible part from excessively deforming comprises a switching disc, a switching shaft and the flexible part, and is characterized in that: one end of the adapter plate is provided with an adapter plate flange, the middle part of the adapter shaft is provided with an adapter shaft flange, the front end of the adapter plate flange is provided with a flexible piece, the flexible piece is sequentially connected with the adapter plate flange and the adapter shaft flange through a plurality of first connecting pieces, and the flexible piece is connected with the adapter shaft through a plurality of second connecting pieces; the first connecting piece is sleeved with the shoulder bushing, the shoulder bushing comprises a bushing body and a bushing shoulder body which are connected end to end, the adapter shaft flange is sleeved on the bushing shoulder body of the shoulder bushing, the length dimension of the bushing shoulder body is larger than the thickness dimension of the adapter shaft flange, and a certain gap is reserved between the front end face and the rear end face of the adapter shaft flange and the adapter plate flange and between the adapter shaft flange and the bushing shoulder body.
Further, the plurality of first connectors and the plurality of second connectors are staggered along the same circumference.
Further, the diameter of the bushing shoulder is greater than the diameter of the bushing body.
Compared with the prior art, the invention has the following advantages:
the invention has simple, compact and reasonable structure, and utilizes the characteristic that the length of the shoulder bushing body is larger than the thickness of the corresponding flange, and the left side and the right side of the movable flange are provided with the deformation allowing spaces, so that the excessive deformation of the coupler can be effectively prevented, and the flexible piece is protected from being damaged.

Detailed Description
The invention will be further described with reference to examples of embodiments in the accompanying drawings, in which:
as shown in fig. 1-2, the invention mainly comprises a adapter plate 1, an adapter shaft 3 and a flexible member 5. One end of the adapter plate 1 is provided with an adapter plate flange 2, and the middle part of the adapter shaft 3 is provided with an adapter shaft flange 4.
The front end of the adapter flange 2 is provided with a flexible piece 5, the flexible piece 5 is sequentially connected with the adapter flange 2 and the adapter shaft flange 4 through a plurality of first connecting pieces 6, and the flexible piece 5 is connected with the adapter shaft 3 through a plurality of second connecting pieces 8. The first and second pluralities of connectors 6, 8 are staggered along the same circumference.
The first connecting piece 6 is sleeved with a shoulder bushing 7, the shoulder bushing 7 comprises a bushing body 7.1 and a bushing shoulder body 7.2 which are connected end to end, and the diameter of the bushing shoulder body 7.2 is larger than that of the bushing body 7.1. The adapter shaft flange 4 is sleeved on a bushing shoulder 7.2 with a shoulder bushing 7, and the length dimension of the bushing shoulder 7.2 is larger than the thickness dimension of the adapter shaft flange 4, so that a certain gap is reserved between the front end face and the rear end face of the adapter shaft flange 4 and the adapter plate flange 2 as well as between the adapter shaft flange and the bushing shoulder 7.2, and the gap allows a deformation space of the flexible piece.
The working principle of the invention is as follows: when the axial displacement of the coupling is within the design range, the adapter shaft flange is not contacted with the adapter flange and the end face of the shoulder body of the lining with the shoulder bush, and when the axial displacement of the coupling is overlarge, the adapter shaft flange is contacted with the adapter flange and the end face of the shoulder body of the lining with the shoulder bush, so that the flexible part is prevented from being deformed continuously, and the flexible part is effectively protected.
