Optimal technical scheme of the present utility model is: the groove of the actuation balance-free type large-torque flexible coupling of described band take-up is located at the inner radius of two butt plates.
Another optimal technical scheme of the present utility model is: the side, outer of two butt plates of the actuation balance-free type large-torque flexible coupling of described band take-up is provided with jack, two bolts of described take-up are for having 90 degree knuckles and having only an end that screw thread is arranged, and the no threaded end of described two bolts is inserted in the described jack of two butt plates.
Another optimal technical scheme of the present utility model is: two bolts of the take-up of the actuation balance-free type large-torque flexible coupling of described band take-up are that straight bolt and two ends all have screw thread, one end and the butt plate of described two bolts spin, the other end connects long nut, and described long nut is a stock gaily decorated basket nut.
The utility model beneficial effect 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 utility model 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, the transmitted power moment of torsion is big, reduces inrush current power, friction, noise free can prolong 4-5 working life doubly.
2, 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 half-coupling to be connected by the rim of the mouth orientation type with butt plate, docks like this that the gap is little, good positioning effect, specious.
3, 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 utility model 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.
4, 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 groove of butt plate and reducing dish, save time, practicality friction.
5, 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.
