DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a double acting cone coupling for interconnecting a shaft and a hub for locking of the two parts in connection to each other in the axial direction and/or against rotation in relation to each other.
Cone couplings for interconnecting a shaft and a hub are previously known which comprise a double-conical ring on one hand, which is slit up in the axial direction and which contacts the shaft or hub and two conical sleeves on the other hand each of which contacts a surface portion of the conical ring and which can be clamped towards each other by means of a screw connection while sliding along the cone surfaces of the conical ring. Such apparatus is shown in the British patent No. 1,390,431 or U.S. Pat. No. 3,430,613.
The said previously known devices are complicated to manufacture since they comprise at least three different parts which must be made matching each other, and the coupling must be manufactured with relatively narrow tolerances in order to make possible an interconnection of a shaft and a hub since the cone sleeves cannot to any substantial degree be expanded or contracted respectively in the radial direction. In many cases it is considered necessary to lock the cone sleeves in relation to one of the parts to be interconnected, for instance the hub and to lock the double conical ring in relation to the other part, for instance the shaft. For providing a clamping together of the two cone sleeves in order to get an acceptable interconnection of the shaft and hub, especially for transmitting torque from one part to the other there, is a need for strong axial forces in the said previously known couplings. Often the slit up conical ring can give different centering of the cone sleeves and thereby of the hub part in relation to the shaft part, whereby an imperfect rotation accuracy is obtained.
The object of the invention is to avoid the above mentioned disadvantages in the previously known couplings and to provide a cone coupling for interconnecting a shaft and a hub, which coupling is simple and can be manufactured at low cost, which gives a good centering, which comprises only few parts, which can move a substantial distance in the radial direction and therefore need not be manufactured with especially narrow tolerances and which has an inner closed flow of forces when used for interconnecting a shaft and a hub, so that the shaft or the hub need not be utilized for the interconnection of the said two parts, and which coupling has small outer dimensions, which can be manufactured in any desired actual lengths.
Further characteristics of the invention will be evident from the following detailed specification in which reference will be made to the accompanying drawings. In the drawings FIG. 1 diagrammatically shows a double-acting cone coupling according to the invention with the parts thereof separated. FIG. 2 is a cross section along line II--II of FIG. 1, and FIG. 3 shows a partial cross section through a shaft and a hub which are interconnected by means of the cone coupling according to FIGS. 1 and 2. FIG. 4 shows a modified embodiment of a coupling according to the invention adapted for connecting a hub to a two-part shaft. FIG. 5 shows a partial cross section through a modified coupling according to the invention. FIG. 6 diagrammatically and strongly exaggeratedly illustrates the function of the coupling.
The apparatus illustrated in FIGS. 1-3 generally comprises an outer cone sleeve 1 and an inner cone sleeve 2 which are designed for being combined and clamped to each other by means of screws 3. The outer cone sleeve 1 is intended to carry a hub 4 or a similar means and the inner cone sleeve 2 is adapted to enclose a shaft 5. For this purpose the outer surface 6 of the outer cone sleeve 1 is formed as a circular cylinder, and likewise the inner surface 7 or the inner cone sleeve 2 is formed as a circular cylinder. At one end each of the outer cone sleeve 1 and the inner cone sleeve 2 has a radially outwards projecting collar 8 and 9 respectively. The collar 9 has
