Description
Technical field
The utility model relates to a kind of transmission device, particularly a kind of safety type elastic coupling flexible coupling.
Background technique
Coupling is used for the diaxon of active machine and working machine is linked together as the motor 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.Though existing coupling can satisfy general job requirement, but there are many defectives: at first, the diaphragm group of existing coupling adopts single layer structure and diaphragm group to be in visible state usually, because motor power when work is very big, can't satisfy intensive work demand and long-time the use working life of individual layer diaphragm group, in case generation deformation of diaphragm group or fracture constitute a threat to personal safety.Secondly, 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 can overcome above-mentioned defective at present.
The model utility content
In order to overcome the defective of prior art, the purpose of this utility model is to have proposed a kind of safe, long service life, specious elastic coupling flexible coupling.
For this reason; the utility model proposes a kind of safety type elastic coupling flexible coupling; comprise two half-couplinves and diaphragm group; described half-coupling is the axle connecting sleeve that an end is provided with flange plate; it is characterized in that: the both sides of described diaphragm group are respectively equipped with a butt plate I and butt plate II; the inboard card of described butt plate I and/or butt plate II is provided with one and is used to block the protective layer of diaphragm group; described butt plate I is connected with the flange plate of two half-couplinves respectively with butt plate II, and the axle connecting sleeve of described two half-couplinves is provided with a circle outer lug boss.
Wherein, be provided with intermediate section between described butt plate I and the butt plate II, described intermediate section is the axle connecting sleeve that two ends are provided with flange plate, is provided with the diaphragm group between the flange plate at intermediate section two ends and butt plate I and the butt plate II.
Wherein, the quantity of described intermediate section is N, is provided with the diaphragm group between the two ends flange plate of each intermediate section, and N is a positive integer.
Wherein, described diaphragm group adopts lamination diaphragm group, be by two-sided rivet with each elastic sheet cross-under, make by hydraulic rain again.
Wherein, be equipped with the rim of the mouth on the flange plate of described two half-couplinves, respectively be located at butt plate I and butt plate II on female mouthful of location dock.
Wherein, establish on the outside card of described butt plate I and butt plate II and a circle groove, an elastic ring is installed in the groove.
Wherein, the inner hole wall of described half-coupling is provided with the clearance groov perpendicular with its axis.
Wherein, be connected with a take-up between described butt plate I and the butt plate II, described take-up comprises two bolts and a long nut, and an end of described two bolts is connected with butt plate, and the other end screws in the tapped hole of long nut.
Wherein, described long nut is gaily decorated basket nut or the inner screwed threaded bush that two ends are threaded the hole; Described bolt is the screwed L shaped bolt of an end, and two not threaded ends of bolt insert respectively in the external diameter hole of butt plate I and butt plate II, and two threaded ends of bolt and long nut spin.
Wherein, described long nut is gaily decorated basket nut or the inner screwed threaded bush that two ends are threaded the hole; Described bolt is the screwed straight bolts in two ends, and an end of two bolts spins with butt plate I and butt plate II respectively, and the two ends of the other end and long nut spin.
The beneficial effects of the utility model are:
1, the utility model has adopted the structure of protective layer, and the diaphragm group is expired when fracture takes place working life, can not fly out and hurt sb.'s feelings; and when the diaphragm group ruptures; part can pound the protective layer inwall of butt plate, sends rapid sound automatically, reminds the operator in time to change the diaphragm group.
2, the utility model adopts the structure of lamination diaphragm group, can make machine initiatively and be in operation by motivation to adjust distance between the diaxon automatically, can compensate generation in service axially, radially, angle is offset, it is more stable, reliable to turn round.Owing to adopt lamination diaphragm group, make coupling under the identical situation of the diameter of axle, rated torque is higher by 50% than other diaphragm coupling, and the transmitted power moment of torsion is big, reduces inrush current power, friction, noise free, working life, existing diaphragm group can prolong 4-5 doubly.
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 utility model adopts be two half-couplinves with two butt plates between dock by the location, rim of the mouth, this structure is docked little, the good positioning effect, specious in gap.
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.Coupling of the present utility model respectively connects a butt plate at the two ends of lamination diaphragm group, between two butt plates, take-up is installed then, both saved material (take-up generally adopts 3-9), improved the whole handling speed of coupling again 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 utility model adopts installs the automatic adjusting play of high-strength elastic ring in the card groove of two butt plates, 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 utility model 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.
