Abstract
The invention discloses a coupling device for a liquid pump and relates to a pump which is provided with the coupling device, wherein a connecting hole is arranged in the coupling device and is a conical hole; a conical sleeve is arranged in the connecting hole; a key groove is arranged in the inside diameter of the conical sleeve; an axial opening is arranged in one side of the conical sleeve; a connecting seat is arranged at the outer end of the conical sleeve; a fixed hole is arranged in the connecting seat; a threaded hole corresponding to the fixed hole in the connecting seat is arranged in the coupling device; when the coupling device is in assembly, the conical sleeve is matched with the conical connecting hole of the coupling device; an inner hole of the conical sleeve is matched with a shaft; the conical sleeve is compressed by a bolt and can automatically enclasp the pump shaft along the axial direction; no gap is formed between the shaft and the coupling device; the coupling device is suitable for connection of a liquid pump shaft; and the coupling device has the advantages of no need of heating assembly, easiness for assembly and disassembly and high assembly precision.
Description
Technical field
The present invention relates to the pump class, is a kind of liquid pump hitch bar specifically.
Background technique
We know that the attachment hole of existing liquid pump hitch bar is a straight hole, this hitch bar; Because attachment hole is straight hole, during assembling, be easy to generate the gap between axle and the hitch bar or magnitude of interference is big; Also need heat assembling when magnitude of interference is big, be difficult for Assembly And Disassembly, assembly precision is low.
Summary of the invention
The technical problem that the present invention solves is, solves to be easy to generate the gap between axle and the hitch bar or magnitude of interference is big, also need heat 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 hitch bar does not have the gap, need not heat assembling; Easy Assembly And Disassembly, the liquid pump hitch bar that assembly precision is high.
Technological scheme of the present invention is: the liquid pump hitch bar, and hitch bar is provided with attachment hole, and 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 hitch bar.
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 that 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 the fixed hole on the connecting base of hitch bar; During assembling, taper sheath cooperates with the taper connection hole of hitch bar, 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 hitch bar; Need not heat assembling, easy Assembly And Disassembly, assembly precision is high.The present invention is applicable to the connection of liquid pump shaft.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention, also is a kind of embodiment's schematic representation; Fig. 2 is the right elevation of taper sheath of the present invention.
Embodiment
Liquid pump hitch bar as shown in the figure is provided with hitch bar 1, and hitch bar 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 with the key matching and fixing hitch bar 1 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, and connecting base 5 is provided with fixed hole 8, the fixed hole 8 corresponding tapped holes that are provided with on hitch bar 1 and the connecting base 5; During assembling, taper sheath 3 cooperates with the taper connection hole of hitch bar 1, and taper sheath 3 endoporus cooperate with axle; Compress taper sheath 3 with screw 2, taper sheath can be held pump shaft vertically automatically tightly, does not have the gap between axle and the hitch bar 1; Need not heat assembling, easy Assembly And Disassembly, assembly precision is high.The connecting base 5 of taper sheath 3 is provided with dismounting tapped hole 7, and during dismounting taper sheath 3, on dismounting tapped hole 7, screwing on ejects screw, taper sheath 3 convenient disassemblies.
