Abstract
The utility model relates to a single -screw pump with crosshead shoe connection structure, including the pump body, install rubber bush in the pump body, rotor screw rod, the transmission shaft be connected with the rotor screw rod and set up sealed in driving motor off -axial portion, characterized in that: the rotor screw rod passes through the crosshead shoe assembly and is connected with the transmission shaft, rotor screw rod in the pump body is half floating structure, installs transition disc between the pump body and driving motor. The advantage is: compare with traditional single -screw pump, this pump need not not set up coupling spindle and universal joint and drive the rotor screw rod and be planet rotary motion around the stator bush, so not only can simplify the single -screw pump structure by a wide margin, reduce single -screw pump's length and size, and can alleviate the weight of pump, still can satisfy that the boats and ships space is little, the requirement of the removal of being convenient for simultaneously.
Description
Technical field
This utility model belongs to displacement type screw pump technology field, and more particularly to one kind has crosshead shoe attachment structure
Single-screw (single screw) pump.
Background technology
Single-screw (single screw) pump is a kind of positive displacement pump, and application is quite varied at present.In shipping industry, in order to reduce ship system
Cause this, improve the utilization rate of capacity of vessel, need to reduce taking up room, due to traditional single-screw (single screw) pump of screw pump or pump group
It is the attachment structure passing through two Universal joint components using three rotary shafts, lead to the overall structure size of pump long, therefore single spiral shell
Bar pump takies the space of cabin than larger.And do not need the occasion of pump conveying high-pressure, big flow medium, the such as dirt on ship at some
Water discharge etc. requires the operating mode not taking up space and being moved easily, and is then difficult to meet above-mentioned operating mode using conventional single-screw (single screw) pump
Require.
Content of the invention
This utility model provides a kind of compact conformation, small volume weight for solving technical problem present in known technology
Light and saving occupation of land space, pumped (conveying) medium widely have the single-screw (single screw) pump of crosshead shoe attachment structure.
This utility model is adopted the technical scheme that by solving technical problem present in known technology：
There is the single-screw (single screw) pump of crosshead shoe attachment structure, including the pump housing, the rubber bushing being arranged in the pump housing, rotor spiral shell
Power transmission shaft that bar is connected with multi-rotor screw and be arranged on sealing outside motor axle it is characterised in that：Described multi-rotor screw
It is connected with power transmission shaft by crosshead shoe assembly, the multi-rotor screw in the described pump housing is semifloating structure, in the pump housing and driving electricity
Transition disc is installed between machine.
This utility model can also adopt the following technical scheme that：
Described crosshead shoe assembly is to be made up of crosshead shoe and two 1/2nd shaft couplings, and described crosshead shoe is system
There is the cylinder of centre bore, the boss being provided with centre bore symmetric configuration in cylindrical both ends of the surface and being connected as a single entity with it,
Described crosshead shoe is moved by the groove of boss and 1/2nd shaft coupling one end and is connected.
The inlet and outlet of the described pump housing is all formed with the screw buckle being easy to connect pipe joint.
This utility model has the advantages and positive effects that：Because this utility model adopts technique scheme, i.e. pump
, by crosshead shoe assembly structure come transmitting movement, rubber bushing is positioned at the pump housing for internal multi-rotor screw and motor axle
Interior, the multi-rotor screw in the pump housing can be made to be in semifloating state, compared with traditional single-screw (single screw) pump, this single-screw (single screw) pump need not arrange connection
Spindle and universal joint, to drive multi-rotor screw to do planet gyration motion around stator liner, so not only can significantly simplify single spiral shell
Bar pump group structure, reduce the length dimension of single-screw (single screw) pump, and the weight of pump can be mitigated, also can meet ship space little, just simultaneously
Requirement in movement.

Specific embodiment
For content of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following examples, and coordinate
Accompanying drawing describes in detail as follows：
Refer to Fig. 1 and Fig. 2, there is the single-screw (single screw) pump of crosshead shoe attachment structure, including the pump housing, be arranged in the pump housing
Power transmission shaft 7 that rubber bushing 2, multi-rotor screw 3 are connected with multi-rotor screw and be arranged on sealing 11 outside motor axle, institute
Stating the pump housing is to be made up of the front pump housing 1, intermediate 4 and the rear pump housing 5.Described multi-rotor screw passes through crosshead shoe assembly 6 and power transmission shaft 7
Connect, described power transmission shaft 7 connects motor axle, the multi-rotor screw in the described pump housing is semifloating structure, so can meet
The motion of multi-rotor screw 3, is provided with motor transitional disk 8 between the pump housing 5 and motor 9.
In the present embodiment, described crosshead shoe assembly 6 is by crosshead shoe 6-1 and two 1/2nd shaft coupling 6-2 structures
Become, described crosshead shoe is the cylinder being formed with centre bore, cylindrical both ends of the surface are provided with centre bore symmetric configuration and
The boss 6-1-1 being connected as a single entity with it, it is recessed with each 1/2nd shaft coupling one end respectively that described crosshead shoe passes through boss
Groove moves and is connected.Described multi-rotor screw 3 is connected with 1/2nd shaft coupling 6-2 of crosshead shoe assembly by pin 10, institute
The one end stating power transmission shaft 7 is connected with another 1/2nd shaft coupling 6-2 of crosshead shoe assembly 6 by pin 10, described biography
The other end of moving axis 7 is connected by pin 10 with motor axle.
In the present embodiment, the import 12 of the described pump housing and outlet 13 are all formed with the screw buckle being easy to connect pipe joint.So
Flexible pipe can be connected by pipe joint, and be fixed by clip clamping, connect without rigid line, and then the sky of cloth pipeline can be saved
Between.
Operation principle of the present utility model is：
Motor 9 drives power transmission shaft 7 to rotate, and power transmission shaft 7 passes through crosshead shoe assembly 6 rotor driven screw rod 3 in rubber
Bushing 2 does planet gyration motion, and the hydraulic pressure intracavity being meshed with rubber bushing in multi-rotor screw forms annular seal space one by one.With
The rotation of multi-rotor screw, annular seal space will move to pump discharge end, thus medium is aspirated through spiral shell from the import 12 of the rear pump housing 5
The outlet 13 that the annular seal space of bar and bushing delivers to the front pump housing 1 is discharged.
Embodiment described in this utility model accompanying drawing is exemplary, is only used for explaining this utility model, and can not manage
Solution is to restriction of the present utility model.
