Description
Technical field
The invention belongs to the technical field on the mechanical transmission part, particularly a kind of coupling of high pulling torque transmission.
Background technique
Coupling is that two axles (driving shaft and driven shaft) that are used for connecting in the different institutions make it the mechanical parts of common rotation with transmitting torque, and the kind of coupling has a lot, for example: flanged joint, oldham coupling, elastic coupling flexible coupling, safety coupling, rigid coupling, flexible coupling etc.; Rigid coupling wherein is because it is simple in structure; Low price, steady in load, stabilization of speed; Can guarantee to be joined under the minimum situation of two axis relativity shifts; Multiselect is used rigid coupling, and rigid coupling also has multiple, and wherein a kind of is that the coupling shell body wall of open circles column type is provided with a plurality of screws; The end of two axles that needs are connected is stretched into to screw in the screw in the center hole of coupling and with screw rotating shaft and coupling is located each other; Its deficiency is: because the center hole of coupling is the cylndrical surface, the moment of torsion between two rotating shafts leans on screw and coupling to transmit, and the moment of torsion that screw transmits is less; In case screw gets loose or quilt is twisted off making coupling connect inefficacy, influences normal torque drive.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, low-cost, be connected reliably with transmission shaft, and can guarantee the coupling of the high pulling torque transmission of transmission stability effectively.
The present invention is achieved in that
A kind of coupling of high pulling torque transmission radially is provided with two groups of orthogonal tapped through holes on the sidewall of hollow cylinder, inwardly be provided with the side plane that parallels to the axis more than on the inner cylindrical surface of described hollow cylinder.
Above-mentioned side plane has one, and a described side plane is arranged on the downside or the right side of the inner cylindrical surface of hollow cylinder, and orthogonal two groups of tapped through holes are separately positioned on the downside and the right side of the sidewall of hollow cylinder.
Above-mentioned side plane has two, and two side planes are arranged on the downside and the right side of the inner cylindrical surface of hollow cylinder respectively mutual vertically, and the sidewall at each place, side is provided with one group of tapped through hole.
Every group of above-mentioned tapped through hole has two respectively, and every group of tapped through hole all is in same the mistake on axis and the plane perpendicular to axis.
One side of the external cylindrical surface of above-mentioned hollow cylinder is provided with the annular boss that hole enlargement forms.
The present invention compares the outstanding advantage of existing technology:
1, the side plane on the coupling inner cylindrical surface of the present invention cooperates with side plane on the transmission shaft and can realize the transmission than high pulling torque; And screw only plays the effect of coupling being carried out axially locating in rotating shaft; Because screw is stressed less; Screw is difficult for twisting off or because of vibrations get loose, the hollow cylinder of coupling can be delivered to the moment of torsion on the axle on another axle in the same old way even if screw gets loose because of moment of torsion in transmission process, and then makes the moment of torsion transmission of coupling big and reliable; Join strength is high, good stability.
2, the present invention can adopt powder metallurgy sintered moulding, and the precision of product is high, and the waste material that raw material produce is few, cost of production is low, is suitable for to do the rigid coupling use.

Embodiment
With specific embodiment the present invention is further described below, referring to Fig. 1-7:
Embodiment 1 (like Fig. 1 and 2): a kind of coupling of high pulling torque transmission, on coupling 1 in cylinder right flank 12 are planes, be equipped with two tapped through holes (11a and 11b) at right flank 12 and downside 13; After the side plane of transmission shaft was connected, circumferential rotation can not take place in transmission shaft and coupling, both can realize self-locking; Guarantee to connect again reliable, and can also accurate positioning, behind the screw of screwing on; More effectively the fixed conveyor axle has guaranteed transmission stability, if all be provided with on two transmission shafts the axial limiting boss of coupling or spacing block set etc.; Even if without screw or bolton; In the same old way can transmitting torque, so its Security, reliability are high, transmitting torque is big.
Embodiment 2 (like Fig. 3 and 4): a kind of coupling of high pulling torque transmission, on coupling 1 in cylinder downside 13 are planes, be equipped with two tapped through holes (11a and 11b) at right flank 12 and downside 13; After the side plane of transmission shaft was connected, circumferential rotation can not take place in transmission shaft and coupling, both can realize self-locking; Guarantee to connect again reliable, and can also accurate positioning, behind the screw of screwing on; More effectively the fixed conveyor axle has guaranteed transmission stability.
Embodiment 3 (like Fig. 5,6,7): a kind of coupling of high pulling torque transmission, on coupling 1 in cylinder downside 12 all are planes with right flank 13, be equipped with two tapped through holes (11a and 11b) at right flank 12 and downside 13; After the side plane of transmission shaft 20 was connected, circumferential rotation can not take place with coupling 10 in transmission shaft 20, both can realize self-locking; Guarantee to connect reliable again; Two planes that are connected with owing to transmission shaft 20 and coupling 10 are connected in addition, thereby the location is more accurate, behind the screw 30 of screwing on; Transmission shaft 20 is fixed in the coupling 10 firmly; And screw is difficult for getting loose in transmission process, and then can transmit bigger moment of torsion, has guaranteed transmission stability to a great extent.
