Abstract
The invention relates to an integral type coupler. The integral type coupler comprises a cylindrical coupler body, and is characterized in that the coupler body is of an integral structure, a shaft hole and a key groove are formed in the center of the coupler body, a plurality of radial holes are formed in the coupler body, and the radial holes are formed in the upper portion and the lower portion of the coupler body respectively and are communicated with the key groove. The integral type coupler is small in size, convenient to install, reliable to use, safe, economic, and low in machining accuracy.
Description
Technical field
The present invention relates to a kind of integrated type coupling, especially a kind of coupling for Under Water Pumps pump shaft, belongs to connection draft gage technical field.
Background technique
The coupling that in prior art, Under Water Pumps pump shaft adopts is generally symmetrical opposite-opening shaft joint, and coupling is the reducing linkage structure that symmetry is split docking, and as shown in Figure 1, the inner chamber of coupling middle part is provided with for connecting the groove of pump shaft and motor shaft.Due to symmetrical opposite-opening shaft joint in use symmetrical two-part by Bolt Connection (as shown in Figure 2), adding man-hour, higher to the required precision of two-part upper bolt hole, thus strengthened difficulty of processing.In addition in use, the part of two symmetries, by Bolt Connection, has also caused the volume of coupling in pump large (as shown in Figure 3, in Fig. 3, A is symmetrical opposite-opening shaft joint).
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of integrated type coupling is provided, volume is little, machining accuracy is lower.
According to technological scheme provided by the invention, described integrated type coupling, comprises columned coupling body, it is characterized in that: described coupling body is monolithic construction, at the center of coupling body, be provided with axis hole and keyway, a plurality of radial holes are set on coupling body.
Described radial hole is separately positioned on the top and the bottom of coupling body.
Described radial hole is connected with keyway.
Integrated type coupling volume of the present invention is little, easy for installation, use is reliable, safety economy, and machining accuracy is lower.
Accompanying drawing explanation
Fig. 1 is the structural representation of opposite-opening shaft joint in prior art.
Fig. 2 is the sectional view of Fig. 1.
Fig. 3 is the behaviour in service schematic diagram of opposite-opening shaft joint in prior art.
Fig. 4 is structural representation of the present invention.
Fig. 5 is the plan view of Fig. 4.
Fig. 6 is behaviour in service schematic diagram of the present invention.
Embodiment
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Fig. 4～Fig. 6: as described in integrated type coupling comprise coupling body 1, axis hole 2, keyway 3, radial hole 4 etc.
As shown in Figure 4, Figure 5, the present invention includes columned coupling body 1, coupling body 1 is monolithic construction, is provided with axis hole 2 and keyway 3 at the center of coupling body 1; As shown in Figure 4, a plurality of radial holes 4 are set on described coupling body 1, in use, by radial hole 4 and screw, coupling and pump shaft, motor shaft is fastening;
As shown in Figure 4, in the top and the bottom of described coupling body 1, be equipped with radial hole 4, be respectively used to coupling body 1 and pump shaft, motor shaft to fix;
As shown in Figure 5, described radial hole 4 is connected with keyway 3; When coupling uses, the key on pump shaft and motor shaft is placed in keyway 3, then by being arranged on screw in radial hole 4, coupling body 1 and pump shaft, motor shaft is fastening, can not take the space (as shown in Figure 6) in too many pump.
Integrated type coupling of the present invention has advantages of that volume is little, easy for installation, uses reliable, safety economy.
