Abstract
The invention relates to an actuation balance-free type single-reducing coupling which comprises two half-couplings, an intermediate section and a diaphragm group, wherein each of the two half-couplings is an axis connecting sleeve provided with a flange at one end; the intermediate section is an axis connecting sleeve provided with flanges at both ends; the external side of the flange at one end of the intermediate section is sequentially connected with the diaphragm group and a butting disc; the external side of the flange at the other end of the intermediate section is sequentially connected with the diaphragm group and a reducing disc; the two half-couplings are respectively connected with the butting disc and the reducing disc in a bayonet positioning mode; the axis connecting sleeves of the two half-couplings and the intermediate section are respectively provided with an outer lug boss; and the diaphragm group is laminated and produced in such a way that all elastic flakes are threaded and connected by double-faced rivets and hydraulically punched. The actuation balance-free type single-reducing coupling can meet precision requirements of 2.5 level dynamic balance without actuation balance at the rotating speed of 10000r/min or below, thereby omitting the working procedure of actuation balance and overcoming the defect of unprepossessing appearance caused by the drilling of the coupling.
Description
Technical field
The invention belongs to a kind of transmission device, particularly a kind of actuation balance-free type single-reducing coupling.
Background technique
Coupling is used for the diaxon of active machine and working machine is linked together as transferring power, and diaxon can not separate during machine run, and after having only machine to stop and connection being taken apart, diaxon could separate.Because during the motor frequent starting, the two ends of this coupling inevitably vibrate, even phenomenon such as deformation, thereby influenced diaxon misalign produced axially, radially, the skew of angle, so existing coupling all need the start Balance Treatment come mass unbalance that the centre of equilibrium causes with overcome above-mentioned may various case, but the complex structure of this coupling, operational sequence is loaded down with trivial details; Simultaneously, keep coupling steady, inevitably boring and cause the inaesthetic defective of its outward appearance on its main body in order to increase weight.So exigence is developed a kind of coupling that solves above-mentioned drawback at present.
Summary of the invention
In order to overcome the defective of prior art, the objective of the invention is to propose the monotropic footpath coupling that a kind of actuation balance-free is handled.
For this reason, the present invention proposes a kind of actuation balance-free type single-reducing coupling, comprise two half-couplinves, intermediate section and diaphragm group, described half-coupling is the axle connecting sleeve that an end is provided with flange plate, described intermediate section is the axle connecting sleeve that two ends are provided with flange plate, the one end flange dish outside of wherein said intermediate section is connected with diaphragm group and butt plate in turn, the other end flange plate outside of intermediate section is connected with diaphragm group and reducing dish in turn, described two half-couplinves adopt the rim of the mouth to be located by connecting with butt plate and reducing dish respectively, be equipped with a circle outer lug boss on the axle connecting sleeve of described two half-couplinves and intermediate section, described diaphragm group is a lamination diaphragm group, its be by two-sided rivet with each elastic sheet cross-under, make by hydraulic rain again.
Wherein, be connected with take-up between described butt plate and the reducing dish, described take-up comprises two bolts and a long nut, one end of one of them bolt is connected with butt plate, the other end links to each other with long nut, and an end of another bolt is connected with the reducing dish, the other end also links to each other with long nut.
Wherein, described long nut is that gaily decorated basket nut or the inside that two ends have a positive and negative tapped hole has right-and-left threaded threaded bush; Described bolt is that two ends have right-and-left threaded straight bolt.
Wherein, the inner hole wall of the axle connecting sleeve of described two and half coupling drives is provided with clearance groov.
Wherein, the flange plate that increases gradually to outer diameter in described reducing dish is served as reasons, its outside card be provided with one with the rim of the flange plate equal diameters of half-coupling.
Wherein, the outer side surface of butt plate is provided with a circle groove, and the rim of described reducing dish is provided with a circle groove, is equipped with an elastic ring in two grooves.
Wherein, described butt plate is the identical flange plate of outer side surface diameter in, the equal diameters of the flange plate of its diameter and connected half-coupling.
Wherein, the quantity of described intermediate section is N, is provided with lamination diaphragm group between the two ends flange plate of each intermediate section, and N is a positive integer.
Beneficial effect of the present invention is:
1, lamination diaphragm group can make machine initiatively and is in operation by motivation and adjust distance between the diaxon automatically, can compensate generation in service axially, radially, angle is offset, it is more stable, reliable to turn round.Diaphragm group of the present invention makes coupling under the identical situation of the diameter of axle owing to adopt lamination diaphragm group, and rated torque is higher by 50% than other diaphragm coupling, and the transmitted power moment of torsion is big, reduces inrush current power, friction, and noise free can prolong 4-5 working life doubly.
2, the present invention has increased the technical characteristics of reducing dish, the big motor diameter of axle can be changed into the little working machine diameter of axle through the reducing dish, transmitting torque is constant, save raw material, no matter initiatively the diameter of axle of machine and working machine is many slightly, power is much, what, the many height of rotating speed of number of poles are all configurable.
3, overlap joint or protruding, groove butt joint outside the half-coupling external diameter of existing coupling adopts, neither attractive in appearance, the butt joint gap is big again, and loading and unloading are difficult, locating effect is bad; The present invention adopts a half-coupling to be connected by the rim of the mouth orientation type with monotropic footpath dish, and second half shaft coupling also is connected by the rim of the mouth orientation type with butt plate, docks like this that the gap is little, good positioning effect, specious.
4, existing coupling adopts single bolt along the distance of adjusting one week of flange plate of two half-couplinves between two half-couplinves, this kind structure is not only used bolt many (generally adopting 12-36), is destroyed the coupling overall aesthetics, goes back waste material and lay day.The present invention adopts an end of intermediate section to connect lamination diaphragm group and butt plate, the other end connects lamination diaphragm group and reducing dish, the structure of take-up is installed between butt plate and reducing dish then, save material (take-up generally adopts 3-9), improved the whole handling speed of coupling greatly, can shorten for 4/5 lay day at most.
5, existing coupling adopts the thin slice adjusting play, comes off easily when meeting vibration, loses the effect of adjusting play, and vibration force is big; Coupling of the present invention adopts installs the automatic adjusting play of high-strength elastic ring in the groove of butt plate and reducing dish, save time, practicality friction.
6, two half-coupling endoporus of existing coupling all need be taked transition fit with the axle external diameter of machine, working machine initiatively, because the diameter of axle is long, with spool in the transition fit cargo handling process, axial plane and half-coupling endoporus often haul, not convenient to load and transport at half-coupling.The present invention is provided with clearance groov in half-coupling, easy to loading and unloading, reduces transition fit length during transition fit, does not damage half-coupling endoporus and axial plane again, reaches the designing requirement of nominal moment of torsion fully through torsion-testing.
