Abstract
A conical sleeve coupling relates to pumps and is provided with a coupling, wherein a connecting hole is arranged on the coupling, the connecting hole is a conical hole, a conical sleeve is arranged in the connecting hole, a key groove is arranged in the inner diameter of the conical sleeve, an axial opening is arranged on one side of the conical sleeve, a connecting seat is arranged on the outer end of the conical sleeve, a fixing hole is arranged on the connecting seat, a threaded hole is arranged on the coupling corresponding to the fixing hole on the connecting seat, when in assembly, the conical sleeve is matched with the conical connecting hole of the coupling, an inner hole of the conical sleeve is matched with a shaft, the conical sleeve is pressed through screws, the conical sleeve can automatically clamp a pump shaft along the axial direction, none gap exists between the shaft and the coupling, heating assembly is not needed, the assembly and the disassembly are easily, the assembly precision is high, and the conical sleeve coupling is applicable to connecting shafts.
Description
Technical field
The present invention relates to the pump class, is a kind of shaft coupling with cone-shaped sleeve specifically.
Background technique
We know, the attachment hole of existing coupling is a straight hole, and this coupling because attachment hole is a straight hole, during assembling, is easy to generate the gap between axle and the coupling or magnitude of interference is big, also needs the heating assembling when magnitude of interference is big, is difficult for Assembly And Disassembly, and assembly precision is low.
Summary of the invention
The technical problem that the present invention solves is, solve and to be easy to generate the gap between axle and the coupling or magnitude of interference is big, also need the heating assembling when magnitude of interference is big, be difficult for Assembly And Disassembly, the problem that assembly precision is low, providing between a kind of axle and the coupling does not have the gap, does not need the heating assembling, easy Assembly And Disassembly, the shaft coupling with cone-shaped sleeve that assembly precision is high.
Technological scheme of the present invention is: be provided with coupling, coupling is provided with attachment hole, the main structure characteristics are, attachment hole is a cone shape hole, is provided with taper sheath in the attachment hole, and the taper sheath internal diameter is provided with keyway, taper sheath one side is provided with axially open, the taper sheath outer end is provided with connecting base, and connecting base is provided with fixed hole, the corresponding tapped hole that is provided with the fixed hole on the connecting base of coupling.
The connecting base of taper sheath of the present invention is provided with the dismounting tapped hole.
The invention has the beneficial effects as follows, because attachment hole is a cone shape hole, be provided with taper sheath in the attachment hole, the taper sheath internal diameter is provided with keyway, taper sheath one side is provided with axially open, and the taper sheath outer end is provided with connecting base, and connecting base is provided with fixed hole, the corresponding tapped hole that is provided with of coupling with the fixed hole on the connecting base, during assembling, taper sheath cooperates with the taper connection hole of coupling, and the taper sheath endoporus cooperates with axle, use the screw in compression taper sheath, taper sheath can be held pump shaft vertically automatically tightly, does not have the gap between axle and the coupling, does not need the heating assembling, easy Assembly And Disassembly, the assembly precision height.The present invention be applicable to the axle with spool be connected.
Description of drawings
Accompanying drawing is a kind of schematic representation of the present invention, also is a kind of embodiment's schematic representation;
Fig. 1 is a kind of structural front view of the present invention;
Fig. 2 is the right elevation of taper sheath of the present invention.
Embodiment
Shaft coupling with cone-shaped sleeve as shown in the figure is provided with coupling 1, and coupling 1 is provided with attachment hole, and attachment hole is a cone shape hole, is provided with taper sheath 3 in the attachment hole, and taper sheath 3 internal diameters are provided with keyway 4, can cooperate closed coupling 1 with the key on the pump shaft.Taper sheath 3 one sides are provided with axially open 6, make taper sheath 3 can hold pump shaft tightly.Taper sheath 3 outer ends are provided with connecting base 5, connecting base 5 is provided with fixed hole 8, and the fixed hole 8 corresponding tapped holes that are provided with on coupling 1 and the connecting base 5 are during assembling, taper sheath 3 cooperates with the taper connection hole of coupling 1, taper sheath 3 endoporus cooperate with axle, compress taper sheath 3 with screw 2, and taper sheath can be held pump shaft vertically automatically tightly, there is not the gap between axle and the coupling 1, do not need the heating assembling, easy Assembly And Disassembly, assembly precision height.The connecting base 5 of taper sheath 3 is provided with dismounting tapped hole 7, and during dismounting taper sheath 3, screwing on dismounting tapped hole 7 ejects screw, taper sheath 3 convenient disassemblies.
