Abstract
Disclosed is a small-power portable motor coupler. The small-power portable motor coupler comprises a cylinder, and the inner diameter of the cylinder is larger than the outer diameter of a driving shaft and a driven shaft; two groups of grooves are respectively formed along the axial direction from two ends to the middle of the cylinder, a group of grooves at the same end comprise two grooves which are symmetrical along a center shaft of the cylinder and are the same in sizes and directions, two groups of through holes which penetrate walls of the cylinder are formed by being vertical to a center line of the cylinder in the direction vertical to center planes of the two grooves, and the distance between the two groups of the through holes and the nearest end face of the cylinder is smaller than the depth of the grooves on the same side. Bolts or screws penetrate the through holes, openings of the two ends of the cylinder are deformed, and the driving shaft and the driven shaft are clamped to achieve torque transmission. The small-power portable motor coupler has the advantages that the requirements of machining accuracy are low, the process is simple, the production is easy, costs are low, phase adjustment is not required during mounting, and mounting is simple, convenient and rapid.
Description
Technical field
The present invention relates to a kind of coupling for transmitting torque, particularly one installs and removes convenient, the simple low power portable motor coupler of manufacturing process.
Background technique
Coupling is parts conventional in mechanical transmission, is mainly used to the intermediate transmission mechanism of joining shaft and axle or joining shaft and other revolution part, to transmit motion and torque.Current common motor coupler utilizes a public sleeve to be connected with the connecting modes such as pin, key or interference fit and diaxon.But the coupling of this structure is owing to using the connecting modes such as pin, key or interference fit, thus requires pin hole processing, keyway on sleeve, and will ensure that pin hole processing, keyway or hub internal bore have certain requirement on machining accuracy, adds difficulty of processing; And in installation process, need adjustment driving shaft phase place and driven shaft phase place, make the two match, add the installation difficulty of coupling, and mounting or dismounting are inconvenient.
Summary of the invention
Goal of the invention: in order to solve the problems of the technologies described above, the invention provides the low power portable motor coupler that a kind of manufacturing process is simple, easy for installation.
Technological scheme: a kind of low power portable motor coupler, comprise a cylindrical drum, described cylindrical drum internal diameter is greater than the external diameter of driving shaft and driven shaft; In axial direction offer two groups of grooves from cylindrical drum two ends respectively to middle part, it is identical about axisymmetric two grooves in cylindrical drum center that one group of groove with one end comprises size direction; On the direction in vertical two groove center faces and vertical circular column casing center line is provided with the through hole that two groups run through cylinder barrel, the nearest end face distance of described two groups of through holes distance cylindrical drum is less than the degree of depth of the side channel that coexists.Bolt or screw, through through hole, make cylindrical drum both ends open place be out of shape, thus clamping driving shaft and driven shaft realize the transmission of moment of torsion.
Wherein, the end of described groove is provided with circular port, and the diameter of circular port is greater than the width of groove.
Wherein, described often group in through hole has one another be unthreaded hole for tapped hole, screw pass through hole and tapped hole fastening.
Wherein, described often two holes organized in through hole are unthreaded hole, fastening by screw bolt and nut.
Beneficial effect: the requirement on machining accuracy of coupling of the present invention is low, technique is simple, and easy to manufacture, cost is low; And do not need the adjustment carrying out phase place in installation process, simple installation is quick.
