Abstract
The invention discloses a cascade structure of a submerged pump for a ship and a stowage motor. The structure comprises a motor shaft, a flat key, a round nut, a pin, and further comprises an electric coupling and a pump coupling coaxially connected. Junction surfaces of the electric coupling and the pump coupling are connected through the pin to form the cascade structure. The electric coupling is a shaft sleeve member of which one end is provided with a flange. An inner hole of the electric coupling is matched with the extending motor shaft and is coaxially locked by the round nut. According to the structure provided by the invention, a cover plate connected by a screw is arranged in the electric coupling facing the outer end face, and the cover plate is axially blocked to form an axial sealing structure to the electric coupling. The pump coupling is a shaft piece with a flange at one end, and a concave seam allowance matched with a convex seam allowance of the electric coupling is arranged on the outer end face of the flange. In the application process of the structure provided by the invention, once faults occur, the pin is detached to separate the submerged pump from the mating motor, so that the structure can be maintained in a targeted manner. Even if damaged pieces are replaced, the cost is low. The structure provided by the invention is in particular suitable for the matched ships and warships.
Description
Technical field
The present invention relates to a kind of Axile connection structure, specifically, the present invention relates to a kind of joint for submersible pump peculiar to vessel and prestowage motor and connect structure.
Background technique
Watercraft engine room is the place that water, vapour, wet goods pipeline and relevant device thereof are installed concentratedly, and the inner space is narrow, and environment is abominable, and in a single day the bilge that particularly is positioned at bottom accumulates water, oil, and is very difficult with conventional utensil removing, adopts submersible pump to remove relatively convenient.On market, commodity submersible pump peculiar to vessel is continued to use the direct connection structure of common submersible pump, is exactly motor shaft is lengthened as pump shaft.The integrated direct connection of this kind is simple in structure, coaxality good, satisfies normal transmission requirement fully.However, integrated direct connection structure effect and bad on submersible pump peculiar to vessel, its reason is no matter pump damages or motor damages, and all must make integral demounting, causes thus that maintenance load is large, to change component costs high, consuming time many.Boats and ships are a kind of mobile carriers on the other hand, have inconvenient maintenance, and accessory is not enough waits practical difficulty.
Summary of the invention
The present invention is mainly for the deficiencies in the prior art, and the joint that proposes a kind of submersible pump peculiar to vessel and prestowage motor connects structure, and this is simple in structure, connection is reliable, dismounting is easy, maintenance cost is low.
The present invention is achieved through the following technical solutions technical goal.
The joint of submersible pump peculiar to vessel and prestowage motor connects structure, and it comprises motor shaft, flat key, round nut, pin, also comprises the coaxial Electricity Federation joint that joins and pump shaft coupling, connects to form joint by pin and connect structure between Electricity Federation joint and pump shaft coupling junction plane.Its improvements are: described Electricity Federation joint is the boss member that an end is provided with flange, flange is provided with outer male half coupling and indent shoulder hole towards the exterior edge face, Electricity Federation joint endoporus coordinates and makes axial locking with round nut with overhanging motor shaft by flat key, in indent shoulder hole, exterior edge face, the cover plate that is connected by screw is installed at the Electricity Federation joint, plate shaft consists of the same sealing configuration of Electricity Federation joint axle to shutoff.Described pump shaft coupling is a flanged (FLGD) axle spare of end, and the flange exterior edge face is provided with the recessed seam that coordinates with the outer male half coupling of Electricity Federation joint.
In said structure, the outer male half coupling of Electricity Federation joint and the recessed seam of pump shaft coupling are circular seam, both Spielpassung, and concavo-convex seam is combined with to be beneficial to installs the location, guarantees coaxial installation.
The present invention compared with prior art has following good effect:
1, similar coupler structure, easy to connect, and dismounting is easy, reliable transmission;
2, coordinate by seam between Electricity Federation joint and pump shaft coupling, accurate positioning is convenient to dismounting or installs, and saves engineering time;
3, the Electricity Federation joint is provided with axial seal structure, intercepts the passage that water immerses motor, and Security is good;
When 4, keeping in repair, submersible pump and prestowage motor are separated, be convenient to keep in repair targetedly, reduce the replacement cost of parts.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings for the below.
Submersible pump peculiar to vessel shown in Figure 1 and the joint of prestowage motor connect structure, it comprises motor shaft 1, flat key 2, round nut 3, pin 4, also comprise the coaxial Electricity Federation joint 5 that joins and pump shaft coupling 8, connect to form joint by pin 4 and connect structure between Electricity Federation joint 5 and pump shaft coupling 8 junction planes.Member shown in Fig. 1 top is Electricity Federation joint 5, and Electricity Federation joint 5 is the axle sleeve that an end is provided with flange, and flange is provided with outer male half coupling and indent shoulder hole towards the exterior edge face.Outer male half coupling is circular seam, and its center is coaxial with Electricity Federation joint 5 axis holes.Outer male half coupling is as supporting pump shaft coupling 8 indent seam positioning datums, and this is simple in structure, and accurate positioning is convenient to dismounting or installs, and greatly saves engineering time.Joint 5 endoporus in Electricity Federation coordinate with overhanging motor shaft 1 by flat key 2, screw on 3 pairs of Electricity Federation joints 5 of round nut and make axial locking on the end thread section of motor shaft 1.For anti-sealing infiltrates in the motor of prestowage from coordinate the gap, the present invention installs the cover plate 7 that is connected by screw 6 at Electricity Federation joint 5 in indent shoulder hole, exterior edge face, cover plate 7 plays the mechanicalness plugging action, although this axial seal structure is simple, sealing effect is fine, can prevent effectively that the prestowage motor entering water from damaging.Described pump shaft coupling 8 is a flanged (FLGD) axle spare of end, and shaft part is used for impeller is installed, and an end face of flange is arranged towards the end face of flange of Electricity Federation joint 5, both also are connected with pin 4 except coordinating by concavo-convex seam, and this joint connects the similar coupler structure of structure, easy to connect, dismounting is easy, reliable transmission.In a single day break down in application process of the present invention, as long as dismounting pin 4 just can separate submersible pump and prestowage motor, be convenient to keep in repair targetedly, even displacement damaged part cost is also lower.
