Abstract
The utility model relates to an integral type coupler. The integral type coupler comprises a cylindrical coupler body. The integral type coupler is characterized in that the coupler body is of an integral structure, the center of the coupler body is provided with an axle hole and a key groove, and a plurality of radial holes are formed in the coupler body. The radial holes are formed in the upper portion and the lower portion of the coupler body respectively. The radial holes are communicated with the key grooves. The integral type coupler is small in size, convenient to install, reliable in use, safe, economical, and low in machining precision.
Description
Technical field
The utility model relates to a kind of integrated type coupling, and 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).
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of integrated type coupling is provided, and volume is little, machining accuracy is lower.
The technological scheme providing according to the utility model, 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 described in the utility model 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 utility model.
Fig. 5 is the plan view of Fig. 4.
Fig. 6 is behaviour in service schematic diagram of the present utility model.
Embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
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 utility model comprises columned coupling body 1, and 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 described in the utility model has advantages of that volume is little, easy for installation, uses reliable, safety economy.
