Than not only volume is big, and structure is slack and undisciplined.Followed by performance is unstable, and service life is short, and manufacturing process is more multiple
Miscellaneous, cost is relatively high.
In the prior art, such as Patent No. 201220228397.6, the applying date is 2012.05.12 " solid control equipment diaphragm
Shaft coupling ", the limiting condition which can reduce natural environment influences the performance of shaft coupling, so that coupling shield meets
Requirement of the petroleum industry about coupling shield secure context, guarantees the safety of execute-in-place.But the invention is completely embedded
Not enough, rotary gap is big, and anti-corrosion capability is poor, needs further improvement for degree.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of fixed shaft coupling of bidirectional buffering diaphragm group
Device.
To achieve the above object, the present invention adopts the following technical scheme: a kind of bidirectional buffering diaphragm group closed coupling, packet
Include first shaft coupling, second shaft coupling, the first screw, the second screw, buffer substrate tablet, primary diaphragm group, secondary diaphragm group, third spiral shell
Nail and the 4th screw, the primary diaphragm group are formed by stacking by multi-disc primary diaphragm, and the secondary diaphragm group is by the second film of multi-disc
Piece is formed by stacking, and buffer substrate tablet, the other end of the primary diaphragm group are embedded between the primary diaphragm group and secondary diaphragm group
It is connected with second shaft coupling, the secondary diaphragm group other end is connected with first shaft coupling, the primary diaphragm and secondary diaphragm
Structure and size it is all the same, be quadrangle do fillet processing class square membrane, the apex angle of the primary diaphragm and second
The apex angle of diaphragm is equidistantly to shift to install, and the radian of the fillet is 1.3rad, first screw, the second screw, third spiral shell
Nail and the 4th screw are multidirectional spring screw.
Preferably, the primary diaphragm group and secondary diaphragm group are equipped with 5 groups, it is located in the middle between 3 groups and is equipped with
Two layers of buffer substrate tablet, 2 groups of outside are equipped with gap between 3 groups of centre, and the height in the gap is 0.3mm.
Preferably, the primary diaphragm group includes 3 primary diaphragms.
Preferably, the secondary diaphragm group includes 3 secondary diaphragms.
The present invention compares compared with the prior art has the advantage that the bidirectional buffering diaphragm group closed coupling structure is tight
It gathers, without lubrication, structural strength is high and does not have running clearance, therefore service life is longer, so that the sensitivity of shaft coupling transmission
Property strong and cushion performance it is superior, simultaneously because the presence of fillet, so that its ability for resisting external carbuncle greatly enhances.
