Abstract
A coupling for a long-spindle pump comprises upper and lower spindles, an elastic retainer ring for the spindles, a shaft coupling and a coupling band. In the spindle end position of connecting the upper spindle with the lower spindle is disposed a I-groove, in which is built-in a Harfu shaft coupling in half. The coupling band is sleeved in the connection position of the upper and lower end of the coupling band is fastened in the lower spindle step position. The elastic retainer ring is mounted in the retainer ring groove of the upper spindle.
Description
[technical field]
The present invention relates to the hitch bar technical field, particularly a kind of coupling device for long shaft pump.
[background technique]
Some occasion requires pump shaft longer, if adopt a bearing, processing is difficulty relatively, often adopts many axles to link up use in practice.Axle is varied with the connecting mode of axle, scyewed joint is arranged, have taper sheath to connect, have Hough folder shell-type connection etc.Some needs special tool in these connecting modes, installs and removes cumbersome; Some is not complete axisymmetric, and there is dynamic unbalance in operation, can influence the stationarity of pump operation.
[summary of the invention]
Task of the present invention provides a kind of coupling device for long shaft pump, and it has mainly solved the technical problem of following two aspects: the one, realize the rigid joint of several axles, and can transmitting torque and axial force; The 2nd, under the prerequisite that guarantees coupled axle coaxality, the mounting or dismounting of axle coupling arrangement are convenient.
For achieving the above object, the present invention proposes a kind of coupling device for long shaft pump, comprise axle 1, lower shaft 7, circlip for shaft 2, shaft coupling 4, coupling band 5, last axle 1 lower end surface connects lower shaft 7 upper-end surfaces, and diaxon is positioned at same axis, the last axle 1 axle head position that is connected with lower shaft 7 all is equipped with " worker " word groove 8, " worker " word groove is embedded in the Harfu shaft coupling 4 of two halves, coupling band 5 is by key 3,6 are fastened in axle 1 position that is connected with lower shaft 7, coupling band 5 lower ends are stuck in the pillow block component level of lower shaft 7 and put, coupling band 5 upper ends connect circlip 2, and circlip 2 is installed in the circlip groove of axle 1; The endoporus of coupling band 5 is that stomidium footpath is big, the step hole that the other end aperture is little; The axle side surface that last axle 1 and lower shaft 7 cooperate with coupling band is coated with a layer chromium.
The present invention compared with prior art, novel structure, esy to use, safe and reliable, volume is little, both can realize the rigid joint of axle and axle, and mounting or dismounting make things convenient for, do not need special special tool, the simple and easy rigidity hitch bar of the present invention is an axially symmetric structure, the operation of axle system can not produce additional dynamic unbalance, and in addition, the present invention makes simply, cost is low, is worthy of popularization.
[description of drawings]
Fig. 1 is a structural representation of the present invention.
Referring to Fig. 1,1 is that last axle, 2 is " worker " word groove for lower shaft, 8 for key, 7 for coupling band, 6 for shaft coupling, 5 for key, 4 for circlip, 3.
[specific embodiment]
Referring to Fig. 1, " worker " word groove is processed at the axle head position of last axle 1 and lower shaft 7, and the axle side surface that cooperates with coupling band 5 is coated with a layer chromium (surface has been not easy thorn, and is convenient when making mounting or dismounting); Key 3 and key 6 are installed in respectively in the keyway of axle 1 and lower shaft 7; Coupling band 5 installs on the axle head of axle 1, exposes " worker " word groove 8, and the spindle nose with two coupled axles is relative then, sets level straight; Harfu shaft coupling 4 setting-ins of two halves in " worker " word groove 8 of axle head, are struck coupling band 5 then toward lower shaft 7 directions, knock coupling band 5 lower ends and be stuck in till the position on pillow block rank of lower shaft 7; At last circlip for shaft 2 is installed in the circlip groove of axle 1 axially locating of the cover 5 that is fixedly connected.Two axles being linked together like this by rigidity, joining shaft is come axially locating and is transmitted axial force by shaft coupling 4, radially by coupling band 5 location, coupling band is by lower shaft step and circlip for shaft 2 axially locating, and (promptly an end internal orifice dimension is big to be designed to CONCENTRIC REDUCER, the other end internal orifice dimension is little), the assembling stroke is short, easy for installation.Between axle and the joint sleeve is the transition drive fit, can guarantee the requirement of the coaxality after diaxon connects.
The connection of taking axle as needs apart is also very convenient, earlier circlip for shaft 2 is split out, and up axle direction knocks coupling band 5, up to exposing shaft coupling, shaft coupling is a branch half, is easy to take out in " worker " word groove of axle head, take out shaft coupling, diaxon just has been separated up and down.Take out key and coupling band, be reduced into two independent axles.
Coupling device for long shaft pump of the present invention is applied on the vertical long shaft pump of new structure, and assembly efficiency improves 30%, has guaranteed the coaxality of shaft coupling, and the safety reliability of pump improves a lot.
