Abstract
The utility model discloses an eccentric bipyramid cover for swift shaft coupling. This off -centre bipyramid cover is including the cover body, the cover body offer with the shaft fit hole, the cover body has the eccentric cylindrical portion of two excircles awl subtotal formed at between two circular cones part, two excircle pyramis branches, eccentric cylindrical portion respectively with the hole cooperation of shaft coupling, the central axis and axle hole center line that two excircle pyramiss are divided coincide mutually, overlaps downthehole side eccentric relatively and are provided with the keyway, all are equipped with the open slot on the two outer circular conical surfaces, with the setting of keyway symmetry, the line of centres central and open slot of keyway passes the center in shaft hole. The utility model discloses a bipyramid cover simple structure, the preparation is simple and convenient, and impact load is effectively born in the shaft hole of eccentric bipyramid cover and the eccentric structure setting of the cover body, avoids the bipyramid cover to bear the torsional impact and becomes invalid and skid, and the shaft coupling uses safe and reliable, reduces the consumption of spare parts, has practiced thrift manufacturing cost.
Description
Technical field
The utility model relates to the transmission part in mechanical transmission, particularly relates to a kind of parts of coupling.
Background technique
Coupling is commonly used in mechanical transmission, and forms standard in mechanical design handbook.The coupling of current use and axle majority are all cylindrical tolerances transition or interference fit, therefore there is dismounting all the time and install inconvenient problem, and therefore most of coupling is scrapped for cannot dismantle, and the standby redundancy consumption of equipment is large, and cost of investment increases; Especially in continuous mass production, the emergency repair time of production line equipment is at full stretch, and coupling dismounting is inconvenient, wastes time and energy, inefficiency, and labor intensity is large, causes repairing very passive simultaneously, is unfavorable for the smooth and easy running of production line.Occurred the coupling that single tapered sleeve is for convenience detach in the market, its single tapered sleeve adopted is a conical surface, is used for driving speed end coupling, bear be the moment of torsion of an expansion sleeve, overlength fitted shaft not too applicable.Problems existing is in use, and single tapered sleeve resistance to shock loads performance of this kind of structure is weak, and high pulling torque easily lost efficacy, thus increases the consumption of standby redundancy, increases cost of production and drops into.
Summary of the invention
The purpose of this utility model is to provide a kind of eccentric two-taper ferrule for quick coupling, and what can bear is the moment of torsion of two expansion sleeves, can be applicable to longer fitting surface, resistance to shock loads performance is strong, safe and reliable, ensure the safe handling of coupling, save production cost.
A kind of eccentric two-taper ferrule for quick coupling, comprise body, body is offered and axle matching hole, the eccentric cylinder part that described body has two outer cone parts and is formed between two tapered segments, two outer cone parts, eccentric cylinder part respectively with the inner hole of coupling, central axis and the axis hole center line of two outer cone parts coincide, keyway relative eccentric side is arranged, two outer conical surface are equipped with opening slot, be symmetrical arranged with keyway, the center of keyway and the line of centres of opening slot pass the center of axis hole.
Further, the large end cross-section diameter of described two outer cone part is less than column part diameter of section, and column part and tapered segment are connected to form step, facilitate installation to put into and dismantle taking-up.
Further, the tapering of the described tapering of two outer cone parts and the circular cone endoporus of length and coupling and length corresponding to the same.
Compared with prior art, beneficial effect is that two-taper ferrule structure of the present utility model is simple, simple for production, the eccentric axis hole of two-taper ferrule and the eccentric structure of body are arranged, effectively withstand shocks load, and avoid bearing torsional impact inefficacy and skid, coupling is safe and reliable, reduce the consumption of spare part spare unit, save cost of production.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the eccentric two-taper ferrule for quick coupling;
Fig. 2 is the left view of the utility model two-taper ferrule.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
From Fig. 1, Fig. 2, a kind of eccentric two-taper ferrule for quick coupling, comprises body 100, body is offered and axle matching hole 101, in FIG, the central axis a of body and the central axis b of axis hole departs from certain distance L, and the load according to coupling calculates.The eccentric cylinder part 103 that described body has two outer cone parts 102 and is formed between two tapered segments, two outer cone parts, column part respectively with the inner hole of coupling, central axis and the axis hole center line of two outer cone parts coincide, in fig. 2, can find out, in axis hole, relative eccentric side is provided with keyway 104, two outer conical surface is equipped with opening slot 105, be symmetrical arranged with keyway, the center of keyway and the line of centres of opening slot pass the center of axis hole.
Preferred as embodiment, the large end cross-section diameter of described two outer cone parts 102 is less than column part 103 diameter of section, and column part and tapered segment are connected to form step, are convenient to installation and put into and dismantle taking-up.
Preferred as embodiment, tapering and the length of the described tapering of two outer cone parts 102 and the circular cone endoporus of length and coupling are corresponding to the same.
Eccentric two-taper ferrule applied range of the present utility model, facilitates the installation and removal of coupling, substantially increases working efficiency.
