Description
Technical field
This utility model relates to technical field of mechanical transmission, particularly relates to a kind of double diaphragm shaft coupling
Device.
Background technology
Diaphragm coupling compensates, by the elastic deformation of diaphragm, the relative displacement being joined two axles, is one
Plant high performance metallic elastic component flexible coupling.Diaphragm coupling strength ratio on the market is relatively
Low, compared with other shaft coupling transmitting equal moment of torsion, its not only volume big, and structure is loose
Collapse.Next to that unstable properties, service life is short, and manufacturing process is more complicated, cost
The highest.
In prior art, such as Patent No. 201220228397.6, filing date 2012.05.12
" solid control equipment diaphragm coupling ", this utility model can reduce the limit state of natural environment
Performance impact to shaft coupling so that coupling shield meets petroleum industry about coupling shield
The requirement of secure context, it is ensured that the safety of execute-in-place.But this utility model is completely embedded
Not, rotary gap is big, and anti-corrosion capability is poor, needs further improvement for degree.
Utility model content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is
Thering is provided a kind of structure compacter, intensity is high, benefits from double diaphragm couplings of life-span length.
The present invention solves the technical scheme that above-mentioned technical problem used: a kind of double diaphragm shaft couplings
Device, including the first shaft coupling, the second shaft coupling, the first screw, the second screw, buffer substrate tablet,
Primary diaphragm group, secondary diaphragm group, the 3rd screw and the 4th screw, it is characterised in that: described
Primary diaphragm group is formed by stacking by multi-disc primary diaphragm, and described secondary diaphragm group is by multi-disc the second film
Sheet is formed by stacking, and is embedded with buffer substrate tablet between described primary diaphragm group and secondary diaphragm group；Described
The other end of primary diaphragm group connects the second shaft coupling, and the described secondary diaphragm group other end connects
There is the first shaft coupling.
Further, described primary diaphragm is the most identical with the structure of secondary diaphragm and size.
Further, the quantity of described primary diaphragm group is 1～3 group, is often all embedded with slow between group
Punching.
Further, the quantity of described primary diaphragm is 2～4.
Further, the quantity of described secondary diaphragm group is 1～3 group, is often all embedded with slow between group
Punching.
Further, the quantity of described secondary diaphragm is 2～4.
Compared with prior art, the utility model has the advantage of: this utility model need not lubricate,
