Abstract

The utility model discloses an adapter coupling. A cylinder is adopted; openings are arranged at two ends; the inner diameter of the cylinder on each opening is respectively greater than the outer diameters of a driving shaft and a driven shaft; a slot is arranged towards the center of each cylinder from each opening along an axis direction of each cylinder; two slots at the same end are symmetrical along the axis of each cylinder; through holes are arranged at the outer walls of two ends of a sleeve; two through holes at the same end are symmetrically distributed along the axis of each cylinder; the plane, on which the two through holes are located, is vertical to the plane on which two slots are at the same end; the distance from each through hole to each opening of the cylinder is smaller than the depth of each slot, and a screw or a bolt passes through the through holes, so that the openings at two ends of the sleeve deform, thereby clamping the driving shaft and the driven shaft. The adapter coupling is low in requirement to the machining precision, simple in process, easy to manufacture and low in cost; the phases of the driven driving shaft and driven shaft are not required to be adjusted in a mounting process, and the mounting process of the coupling is simplified.

Description

Case butt coupling
Technical field
The present invention relates to coupling, relate in particular to a kind of motor coupler of small-power drive line.
Background technique
Existing box coupling is to utilize a public sleeve to link with the connecting modes such as pin, key or interference fit and diaxon.This structure has following drawback:
1. owing to will use the connecting modes such as pin, key or interference fit, thereby requirement and will guarantee that pin hole processing, keyway or sleeve endoporus have certain machining accuracy at sleeve pin hole processing, keyway, has increased difficulty of processing;
2. in installation process, need to adjust driving shaft phase place and driven shaft phase place, the two is complementary, increased the difficulty that coupling is installed, and mounting or dismounting are inconvenient.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of case butt coupling, preparation process is simple, and is easy for installation.
The technical solution adopted for the present invention to solve the technical problems is: adopt a cylindrical drum, both ends open, the internal diameter of opening cylindrical drum is respectively greater than the external diameter of driving shaft and driven shaft, from opening along the cylindrical drum central axis direction to the cylindrical drum center grooved, two flutings of same end are along axisymmetric in the cylindrical drum, outer wall at the sleeve two ends is opened the hole, two through holes of same end are symmetrical along the cylindrical drum axis, and plane, two through hole places and same end two flutings plane, place is vertical, through hole is apart from the distance of the cylindrical drum opening degree of depth less than fluting, screw or bolt pass through hole, so that the distortion of sleeve both ends open place, thereby clamp driving shaft and driven shaft.
The end of described fluting is circular hole, and the diameter of circular hole is greater than groove width.
Described through hole is unthreaded hole, and bolt passes behind the symmetrical through hole by fastening nuts.
Have one in two symmetrical through holes for screw, screw passes behind another through hole fastening by this screw.
The invention has the beneficial effects as follows: the requirement on machining accuracy of coupling of the present invention is low, and technique is simple, and is easy to manufacture, and cost is low; In installation process, need not carry out any adjustment to the phase place of the master and slave moving axis of transmission, simplify the installation process of coupling.
Description of drawings
Fig. 1 is the structural drawing of coupling of the present invention;
Fig. 2 is the structural drawing of the another kind of coupling of the present invention;
Among the figure: 1 is that axle, 2 is that screw, 3 is that sleeve, 4 is nut.
Embodiment
Case butt coupling of the present invention is a cylindrical drum, both ends open, the internal diameter of opening cylindrical drum is respectively greater than the external diameter of driving shaft and driven shaft, from opening along the cylindrical drum central axis direction to the cylindrical drum center grooved, two flutings of same end are along axisymmetric in the cylindrical drum, outer wall at the sleeve two ends is opened the hole, two through holes of same end are symmetrical along the cylindrical drum axis, and plane, two through hole places and same end two flutings plane, place is vertical, through hole is apart from the distance of the cylindrical drum opening degree of depth less than fluting, screw or bolt pass through hole, so that the distortion of sleeve both ends open place, thereby clamp driving shaft and driven shaft.
The end of described fluting is circular hole, and the diameter of circular hole is greater than groove width.
Described through hole is unthreaded hole, and bolt passes behind the symmetrical through hole by fastening nuts.
Have one in two symmetrical through holes for screw, screw passes behind another through hole fastening by this screw.
The present invention is further described below in conjunction with drawings and Examples.
Embodiment one
This coupling embodiment's structure as shown in Figure 1.This coupling is comprised of screw 2, sleeve 3.Sleeve 3 two ends have abnormity mouthful, have the required hole of mounting screw 2 on the cylinder circumference, and this Kong Yiduan is unthreaded hole, and the other end is tapped hole, and screw 2 tapped hole on the sleeve 3 of packing into is tightened screw 2, and the abnormity of sleeve 3 mouthful will diminish, so that axle 1 is clamped.
Embodiment two
This coupling embodiment's structure as shown in Figure 2.This coupling is comprised of screw 2, sleeve 3 and nut 4.Sleeve 3 two ends have abnormity mouthful, have the required hole of mounting screw 2 on the cylinder circumference, and this hole is unthreaded hole, and screw 2 is tightened tight screw 2 by the nut 4 of screwing on of the unthreaded hole on the sleeve 3 with nut 4, and the abnormity of sleeve 3 mouthful will diminish, so that axle 1 is clamped.
