Abstract
The invention relates to a coupling device, which comprises an intermediate coupling component and is characterized in that one end of the intermediate coupling component is connected with a pump-side coupling component through a diaphragm component; and correspondingly, the other end of the intermediate coupling component is connected with a side-end coupling component through a diaphragm component. By adopting the coupling device, the corrosion resistance is improved, the resistant temperature is high and lubricating oil is not required. At the same time, allowable rotating speed is high, high torque can be transmitted and the counterforce during axial and radial displacement and angular deflection is small. Moreover, the coupling device is suitable for larger axial and radial displacement and angular deflection, the axial stiffness and the bending stiffness are smaller and the coupling device has certain damping and shock absorbing capacities. Besides, the weight and the size are small, the structure is simple and the coupling device is convenient to disassemble and assemble and can meet the needs of different devices.
Description
Technical field
The present invention relates to a kind of shaft coupling apparatus, relate in particular to a kind of coupling system.
Background technique
The chemical centrifugal pump coupling system of being sold in the market, even also do not have any revolution gap when bearing load, even if when having deviation to produce load, coupling still is the rigid of transmission moment of torsion.In running up, generation high temperature makes the relative displacement of between centers increase and makes bearing load strengthen and cause the deviation in the system, all possibly cause axle, the damage that bearing or coupling are too early.Make a whole set of water pump system shorten greatly working life
Summary of the invention
The objective of the invention is to overcome the above problem that existing technology exists, a kind of coupling system is provided.
For realizing a kind of coupling system of the object of the invention; Include the intermediate shaft coupling assembly; It is characterized in that: an end of described intermediate shaft coupling assembly is connected with the pump side coupling assembly through diaphragm unit, and the other end of said intermediate shaft coupling assembly is connected with the side coupling assembly through diaphragm unit.
Further, above-mentioned a kind of coupling system, wherein, described diaphragm unit includes the diaphragm group that diaphragm constitutes, and is equipped with bolt on the connection termination of said diaphragm group, and the bolt two ends are provided with nut.
Further, above-mentioned a kind of coupling system, wherein, described nut is the hexagonal locking nut.
Further, above-mentioned a kind of coupling system, wherein, the side of said diaphragm group is provided with packing ring.
Further, above-mentioned a kind of coupling system, wherein, described diaphragm group has at least ten diaphragms to pile up composition.
Again further, above-mentioned a kind of coupling system, wherein, described pump side coupling assembly is provided with the side coupling assembly and is connected groove, is provided with clamping bolt in the described connection groove.
Adopt technological scheme of the present invention, it is corrosion-resistant, and is high temperature resistant, need not lubricant oil.Simultaneously, rotating speed allowable is high, but and transmitting large torque, axially, counter-force is little when radial displacement and angular deflection.And, be applicable to bigger axially, radial displacement and angular deflection, axially stiffness and bending stiffiness are less, and certain damping and damping capaicty are arranged.Moreover weight and size is little, and is simple in structure, and easy accessibility can adapt to different device needs.
