Seal structure seals, and so its cost is the highest.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of close for dredge pump
Seal structure, by utilizing the cooperation of positioning sleeve and adapter sleeve, it is possible to is not affecting main shaft work
Under situation, ensure the work efficiency of main shaft efficiently.
The technical solution of the utility model is as follows:
A kind of sealing structure for dredge pump, including main shaft, the head at described main shaft is provided with
Groove, engages with end cap and connects, and forms a room, set between described main shaft and described end cap
The bearing being located on described main shaft is positioned at described room, is also arranged with location on described main shaft
Set, described positioning sleeve connects has adapter sleeve, equipped with location between described adapter sleeve and described bearing
Block, connects on the top of described positioning sleeve and described adapter sleeve and has press strip, one end of described press strip
Stretching in described room, described press strip is paralleled with described main shaft.
Further, the head diameter of described positioning sleeve is more than the diameter at middle part, described positioning sleeve
Head be connected with described adapter sleeve by securing member.
As preferably, described adapter sleeve is provided with extension block, and described locating piece is Z-type structure,
Described adapter sleeve matches with described locating piece.
Beneficial effect: this utility model, by utilizing the cooperation of positioning sleeve and adapter sleeve, recycles
Bearing and the combination of locating piece, be fixed finally by press strip, it is possible to is ensureing transmission efficiency
On the premise of, significantly lift-off seal effect.

Every other embodiment, broadly falls into the scope of this utility model protection.
Embodiment
A kind of sealing structure for dredge pump, including main shaft 1, at the head of described main shaft 1
Being provided with groove 9, engage with end cap 2 and connect, described main shaft 1 can connect during rotating
Logical described end cap 2 unitary rotation, and transmission therebetween is the most direct.
A room 10 is formed, at described room between described main shaft 1 and described end cap 2
Being provided with bearing 3 in 10, described bearing 3 is set on described main shaft 1, on described main shaft 1
Also being arranged with positioning sleeve 5, described positioning sleeve 5 connects adapter sleeve 6, described adapter sleeve 6 with
Equipped with locating piece 4 between described bearing 3, described locating piece 4 is Z-type structure, by utilizing
Described locating piece 4 can form the protection to described bearing 3, and the most described adapter sleeve 6 can
Form spacing to described locating piece 4, so can during rotating when described main shaft 1
Along with described main shaft 1 rotates, in the process without making described locating piece 4 and described master
Axle 1 keeps certain gap, therefore, it is possible to form effective sealing.
Fix, described in order to make described positioning sleeve 5 and described adapter sleeve 6 carry out position
The top of positioning sleeve 5 and described adapter sleeve 6 connects has press strip 7, one end of described press strip 7 to stretch
Enter to described room 10, the middle part of described press strip 7 be positioned at described positioning sleeve 5 and described tightly
Admittedly the centre position of set 6, described press strip 7 is made to parallel with described main shaft 1, the most described pressure
Bar 7 can keep balance, and the end of described press strip 7 contacts with described end cap 2, it is possible to anti-
Only there is acclivitous phenomenon in it.
The present embodiment is provided with extension block 8 on described adapter sleeve 6, owing to described locating piece 4 is
Z-type structure, seals, by utilizing described extension block 8 to be formed, the effect coordinated, has simultaneously
It is beneficial to install.
It is described in greater detail below in conjunction with concrete installation process, by sheathed for described positioning sleeve 5
On described main shaft 1, by the head of described positioning sleeve 5 by securing member and described adapter sleeve 6
It is connected, then described locating piece 4 is matched with described extension block 8, at described main shaft 1
Upper sheathed bearing 3, spacing by utilizing described locating piece 4 to carry out, finally by described end
Lid 2 engages with described main shaft 1 and to connect, and is inserted in described end cap 2 by described press strip 7, presses
The top of bar 7 props up, by above technical scheme with described end cap 2 phase, it is possible to carry out efficiently
Sealing, and assemble process simple and fast.
Above-described is only preferred implementation of the present utility model, it is noted that for this
For the those of ordinary skill in field, on the premise of creating design without departing from this utility model,
