Description
Technical field
The utility model relates to turbine industry, high-accuracy lathe, pump and requires high rotating speed, high moment of torsion, high-quality mechanical transmission, it specifically is a kind of diaphragm coupling, it connects the axle head of two transmission devices, be used for transmitting torque and absorption axes to, radially reach angle displacement.
Background technique
Diaphragm coupling belongs to a kind of of coupling, is used for diaxon is linked together, and diaxon can not separate during machine run, and after having only machine to stop and connection being taken apart, diaxon could separate.But diaphragm coupling is different from other coupling again, diaphragm coupling is a kind of special high technology engineering goods that high stiffness, high strength have high elasticity simultaneously that integrate, but axially, radially reaches angular displacement what transmit high-power, high-revolving while compensating shaft system.Though flexible laminated membrane coupling also can compensating shaft system axially, radially reach angular displacement, domesticly also produced this coupling.But this kind coupling can't satisfy big profile shaft system high speed, high power, highi degree of accuracy, need not to lubricate, the requirement of long service life, and also easy to wear, need often replacing, its performance can't be compared with diaphragm coupling.At present, the producer that can produce diaphragm coupling in the world has only three families: German BHS, Japanese EKK, U.S. Cop-flex.Domestic also do not have producer can research and develop the production diaphragm coupling at present, and the import diaphragm coupling prices are rather stiff, do not sell us abroad again for the diaphragm coupling of specific use, such as helicopter, submarine etc.; At home, have only the sub-fraction machinery in minority field using diaphragm coupling.Diaphragm coupling is because of its distinctive performance and plurality of advantages, can compensate deficiency and assembly error in the mechanical parts processing, makes machinery under the situation of self deficiency, all right good running, precision optical machinery is better turned round, reduce noise and vibrations, increase working life.This just is badly in need of China research and development and produces the diaphragm coupling of oneself.
The model utility content
For solving the present situation that the import diaphragm coupling costs an arm and a leg and can't buy the special applications diaphragm coupling, the utility model provides a kind of novel diaphragm coupling, it has and the external identical performance of diaphragm coupling, but promptly axially, radially reaches angular displacement what transmit high-power, high-revolving while compensating shaft system.
The technical solution of the utility model is as follows:
A kind of diaphragm coupling, this diaphragm coupling is provided with and drives reel, membranous disc, intermediate sleeve, every tube, be driven the end reel, membranous disc is for being provided with the integrative-structure that rigid membrance, the other end are provided with the membranous disc flange every tube one end, the intermediate sleeve two ends connect the membranous disc flange end of membranous disc respectively, and the rigid membrance end of two membranous discs connects the driving reel respectively and is driven the end reel.
The described membranous disc outside is equipped with membranous disc protection axle sleeve.
Described driving reel or the rigid membrance that is driven end reel and membranous disc are connected by flange employing bolt.
Described membranous disc flange adopts bolt to be connected with intermediate sleeve by flange.
Described membranous disc adopts monofilm dish single-curved surface structure, and the rigid membrance outer side surface of assembling back membranous disc is a curved surface, and the inboard face of rigid membrance is the plane.
The utlity model has following advantage:
1, the utility model two axial ends is connected by flange respectively, and flange is connected with membranous disc by bolt, and two membranous discs are connected with intermediate sleeve by bolt.Moment of torsion is delivered to the flange of the other end by bolt, membranous disc, bolt, and then passes to another equipment by the flange of equipment one end, and diaphragm coupling has so just been realized the moment of torsion transmission.In addition, external diaphragm coupling has two membranous disc single-curved surfaces, and two kinds of monofilm dish hyperboloids, the utility model diaphragm coupling are monofilm dish single-curved surface, and processing and production are then more convenient, more save.
2, the utility model diaphragm coupling can compensate the axial displacement of connected two axles.
3, the utility model diaphragm coupling can compensate the radial displacement of connected two axles.
4, the utility model diaphragm coupling can compensate the angle displacement of connected two axles.
5, the utility model diaphragm coupling need not lubricate or safeguard.
6, the very close to each other and wearing and tearing of the utility model diaphragm coupling.
7, the utility model membranous disc element can both keep their flexible characteristic in whole working life.
8, the utility model diaphragm coupling has reproducible, high dynamic balance performance.
9, the utility model diaphragm coupling is subjected to windage little, has absorbing, reduces the function of noise.
10, the utility model diaphragm coupling can be used for transmitting high moment of torsion and high-revolving occasion.
