Abstract
The invention relates to a diaphragm coupling. The diaphragm coupling comprises an input diaphragm, a duplex diaphragm, an output diaphragm and a supporting plate nut assembly, wherein one end of the input diaphragm is connected with a power output end, one end of the output diaphragm is connected with the power output end, one end of the duplex diaphragm is connected with the input diaphragm, the other end of the duplex diaphragm is connected with the output diaphragm, and at least one of two connecting positions is connected through the supporting plate nut assembly. The diaphragm coupling has a simple structure and light weight, can work under severe environments, is applicable to high-temperature corrosive places, has good buffering and shock absorbing capacities and has the advantage of easiness in machining, assembling, disassembling and maintenance.
Description
Technical field
The present invention relates to a kind of diaphragm coupling, be mainly used in compensating the distortion of transmission part and manufacture deviation to the impact of transmission.
Background technique
Coupling, for connecting two transmission paries, compensates various deviation and malformation, and the motion of transmitting between them and power.First being the motion transmission such as to ensure between two transmission paries, is secondly reliable connection.Because each transmission part can produce error in assembling with in manufacturing, the design of coupling needs the requirement considering to manufacture assembling, also needs to arrange unnecessary freedom of movement with compensating axial, angle, radial various deviation and part distortion.From its function, be very high to the requirement of coupling design.At present, coupling generally adopts coupling as shown in Figure 1, and the two ends of coupling are provided with diaphragm group, then are connected with flange plate by diaphragm group.Diaphragm group is that one group of very thin stainless steel sheets is formed by stacking, every sheet stainless steel sheets thickness is 0.2 ~ 0.3mm, and in order to ensure the reliability of work, need will be coated with molybdenum disulfide or teflon dry lubricant on the surface of diaphragm, thickness is 0.005 ~ 0.015mm.Although this coupling has absorbing, damping capacity, because needs arrange intermediate section, and diaphragm group to be set at two ends, make small product size comparatively large, meanwhile, the requirement for diaphragm is also higher, require very high in processing and assembly process, in use also will be coated with oiling agent, complex procedures.Therefore existing coupling volume is large, processing, assembling, dismounting, safeguard more difficult.
Summary of the invention
The object of this invention is to provide a kind of volume little, and the diaphragm coupling of easily processing, easily assembling, quick detachable, easy care.
Technological scheme of the present invention is: diaphragm coupling comprises input membranous disc, duplex membranous disc, exports membranous disc, plate nut assembly.Input membranous disc one end is connected with clutch end, the other end is dish type, export membranous disc one end to be connected with clutch end, the other end is dish type, the two ends of duplex membranous disc are dish type, the disc-shaped part of one end is connected with the disc-shaped part of input membranous disc, and the disc-shaped part of the other end is connected with the disc-shaped part exporting membranous disc, and has at least a place to be connected by plate nut assembly in two attachment portions, place.Described plate nut assembly comprises bounding means, nut, bolt, described bounding means is fixed on the disc-shaped part of output membranous disc, bounding means is provided with axial groove, one end of nut is provided with outward extending boss, described boss is positioned at the groove of bounding means, and when boss is positioned at groove, boss and groove exist gap, the disc-shaped part of bolt through duplex membranous disc and the disc-shaped part of output membranous disc, and nut is installed.The disc-shaped part of described input membranous disc, duplex membranous disc and output membranous disc is provided with web, and described web is through shot blast, and thickness, between 1.0-1.5mm, is preferably 1.1mm.
Plate nut of the present invention adopts floating connection mode, can be good at like this compensating input membranous disc and exports between membranous disc two axial lines due to axial, radial, angular displacement that the impact etc. of the distortion after foozle, alignment error, carrying and temperature variation causes.Very thin elasticity membranous disc is adopted to transmit the moment of torsion of driving and driven part, without the need to maintenance, easy accessibility.Shot blast is carried out to web surface, its fatigue strength can be improved.Structure of the present invention is simple, lightweight, can work in the presence of a harsh environment, be applicable to the occasion that high temperature has corrosion, have good buffering, vibration absorption ability, has the advantage of easy processing, easily assembling, quick detachable, easy care.
