Abstract

The utility model discloses an eccentric quick coupling which comprises a plurality of half couplings and a quick change device. The quick change device comprises eccentric taper sleeves which are arranged in the half couplings in a sleeved mode, the outer taper faces of the middle portions of the eccentric taper sleeves are matched with inner taper holes of the half couplings, and cylindrical inner holes of the eccentric sleeves are in interference fit or transitional fit with matching shafts. Key grooves are formed in the eccentric taper sleeves, and opening grooves are formed in the upper portions of the outer taper faces. The quick change device further comprises round nuts and retreat stopping pads. Fasteners are used for enabling the eccentric taper sleeves and the half couplings to be connected into a whole through threaded holes in the cylindrical faces at the large ends of the eccentric taper sleeves, the round nuts are mounted on the threaded sections of the small ends of the eccentric taper sleeves, and the round nuts enable the retreat stopping pads to be pressed on the end faces of the half couplings. Under the premise that the fit tolerance of the coupling and a shaft is guaranteed, dismounting and mounting can be conducted conveniently, the coupling can be repeatedly used, the working cost is lowered, and the working efficiency is improved.

Description

A kind of quick coupling of bias

Technical field

The utility model relates to the transmission part in mechanical transmission, relates in particular to a kind of coupling.

Background technique

Coupling is commonly used in mechanical transmission, and in mechanical design handbook formation standard; In the use of coupling in the past, coupling and axle majority are all cylinder tolerance interference fit, therefore there is all the time dismounting and inconvenient problem is installed, most of coupling are all to scrap because cannot dismantle, thereby cause larger spare part loss, in continuous mass production, require the repairing time of production line equipment at full stretch especially, so the old coupling of dismounting inconvenience is just very passive in repairing.

Summary of the invention

Problem to be solved in the utility model is to provide a kind of novel coupling, it,, guaranteeing, under the prerequisite of coupling and axle fit tolerance, can to carry out easily dismounting, can reuse coupling, therefore both reduce job costs, improved again working efficiency.

The quick coupling of a kind of bias of the utility model, it comprises several half-couplings, it also comprises fast shifter, fast shifter comprises eccentric taper sleeve, eccentric taper sleeve is contained in half-coupling, the male cone (strobilus masculinus) at its middle part matches with the internal taper hole of half-coupling, and its cylinder endoporus and fitted shaft interference are joined or transition is closed; The inside of eccentric taper sleeve is processed with keyway, and male cone (strobilus masculinus) top is processed with opening slot.

As this novel a kind of optimal way, fast shifter also comprises round nut, retaining pad, it is in aggregates that the tapped hole of fastening piece by cylndrical surface, eccentric taper sleeve major part one end connects itself and half-coupling, on the thread section of eccentric taper sleeve microcephaly one end, round nut is housed, round nut is pressed on retaining pad on the end face of half-coupling.

The utility model is by existing half-coupling and axial cylindrical fit tolerance place, increases by an eccentric taper sleeve, and the endoporus of cover is joined by ringfeder Common Difference & Cooperation axle cunning, the external diameter of cover and coupling taper fit, and be provided with eccentric structure and prevent impulsive load.Like this when coupling assembles, can slide to join easily and be in place, and tighten up and make taper sheath tensioner reach the needed fit tolerance of coupling by round nut, when reaching tolerance, with thrust pad, pin tolerance, simultaneously, because coning sleeve is eccentric structure, can prevent well that impulsive load from causing the loosening of tapered sleeve, the Security while having guaranteed work; When needs keep in repair coning sleeve, as long as axle is taken out from its endoporus, coning sleeve is Spielpassung with coordinating of half-coupling, can take out easily.Because eccentric bushing end face is provided with two jackscrew positions, when needs are dismantled, only need to push up at end face one with screw, tapered sleeve is just loosening, thus coupling has just been lifted down.

Therefore this novel coupling, guaranteeing, under the prerequisite of coupling and axle fit tolerance, can to carry out easily dismounting, can reuse coupling, has both reduced job costs, has improved again working efficiency.

Embodiment

From Fig. 1, Fig. 2, Fig. 3, the quick coupling of a kind of bias of the utility model, it comprises several half-couplings 4, it also comprises fast shifter, fast shifter comprises eccentric taper sleeve 3, eccentric taper sleeve 3 is contained in half-coupling, and the male cone (strobilus masculinus) at its middle part matches with the internal taper hole of half-coupling 4, its cylinder endoporus and fitted shaft interference or transition fit; The inside of eccentric taper sleeve 3 is processed with keyway, and male cone (strobilus masculinus) top is processed with opening slot 6.

As this novel a kind of optimal way, fast shifter also comprises round nut 1, retaining pad 2, fastening piece makes itself and half-coupling 4 connect in aggregates by the tapped hole 5 of eccentric taper sleeve 3 cylndrical surface, major part one end, on the thread section of eccentric taper sleeve 3 microcephaly one end, round nut 1 is housed, round nut 1 is pressed on retaining pad 2 on the end face of half-coupling 4.Its advantage is: 1, after eccentric taper sleeve installation in position, by round nut and retaining pad lockable tolerance; 2, when coupling need to be dismantled, only need unclamp round nut, then with end face jackscrew, one push up gently, just can make coning sleeve get loose, thereby coupling is dismantled rapidly.

The utility model is by existing half-coupling and axial cylindrical fit tolerance place, increases by an eccentric taper sleeve, and the endoporus of cover is joined by ringfeder Common Difference & Cooperation axle cunning, the external diameter of cover and coupling taper fit, and be provided with eccentric structure and prevent impulsive load.Like this when coupling assembles, can slide to join easily and be in place, and tighten up and make taper sheath tensioner reach the needed fit tolerance of coupling by round nut, when reaching tolerance, with thrust pad, pin tolerance, simultaneously, because coning sleeve is eccentric structure, can prevent well that impulsive load from causing the loosening of tapered sleeve, the Security while having guaranteed work; When needs keep in repair coning sleeve, as long as axle is taken out from its endoporus, coning sleeve is Spielpassung with coordinating of half-coupling, can take out easily.

The utility model has thoroughly changed the friction tight connection mode of coupling tolerance, can easily mount and dismount, thereby can reuse, reduce loss, life-saving, produces considerable economic benefit, especially in continuous mass production, connect soon coming into operation of coupling breakdown repair efficiency is improved greatly, thereby make continuous mass production direct motion have reliable assurance, the economic benefit that whole system produces is difficult to estimate.

Coupling of the present utility model is not limited to coupling as shown in Figure 1, and it had both gone for the whole coupling of speed reducer high speed axle head, also applicable to the various coupling of speed reducer low speed axle head.
