Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
The invention provides one kind plus grey conveying worm, including housing 1 and tail bearing part, tail bearing part bag
Tailing axle 8, axle sleeve 10 and rolling bearing 6 are included, tailing axle 8, axle sleeve 10, rolling bearing 6 are mutually arranged to form an entirety, and by axle
Case 3, bearing suspension 2 is held to be fixed with housing 1.
Tail bearing part as shown in Figure 2, axle sleeve 10 is set on tailing axle 8, and axle sleeve 10 is identical with the length of tailing axle 8,
The end of axle sleeve 10, i.e., away from the one end for adding grey conveying worm agent structure, be arranged with rolling bearing 6, rolling bearing 6, axle
The end profile of set 10 and tailing axle 8 is concordant, and tailing axle 8 is rotated under the drive of drive apparatus, and axle sleeve 10 is being rolled with tailing axle 8
Rotated in bearing 6, rolling bearing 6 is rolled with axle sleeve 10 and coordinated, and abrasion is reduced, it is to avoid the sinking of conveyor screw, so as to influence spiral
The even running of conveyer.
On the terminal outboard surface of tailing axle 8, back-up ring 11 by bolt it is coaxial with tailing axle 8 fixation, back-up ring 11 with diameter greater than
The external diameter of axle sleeve 10, so that the edge of back-up ring 11 extends axle sleeve 10, and mutually overlaps with the end face outside of rolling bearing 6 and compresses,
Fixed effect is played to rolling bearing 10, is matched somebody with somebody between rolling bearing 6, tailing axle 8 and axle sleeve 10 while can also play and seal up
Close the effect in gap.In the opposite side of rolling bearing 6, towards the side for entering grey conveying worm main body, sealing ring 12 is additionally provided with,
So as to further fix position of the rolling bearing 6 on axle sleeve 10.In the outside of axle sleeve 10, pressing has bearing housing 3, bearing housing 3
It is fixed together with axle sleeve 10, the pressing of rolling bearing 6, forms an overall structure, rolling bearing 6 can be rolled on bearing housing 3,
Bearing housing 3 is fixedly mounted by bearing suspension 2 with housing 1, for ease of dismounting, bearing housing 3 and bearing suspension 2 can be passed through into bolt
It is fixed.
To protect the overall structure of tail bearing part, it is to avoid there is foreign matter to enter tail bearing components interior, in afterbody axle
The end of bearing portion part, is additionally provided with external fastening element, and in the present invention, external fastening element is such as the bearing gland 5 in Fig. 2, bearing gland 5
Section it is substantially U-shaped, two sides of U-shape structure carry flanging, and hemmed edges are fixed with bearing housing 3 with bolt, so as to lead to
The fitted bearing case 3 of bearing gland 5 is crossed, axle sleeve 10, rolling bearing 6, tailing axle 8 and back-up ring 11 are closed, protect whole afterbody
Parts of bearings.There is pressing end in the inner side of bearing gland 5, pressing end is pressed in the end face outside of rolling bearing 6.Such as Fig. 2
Shown, the edge of back-up ring 11 is compressed fixes rolling bearing 6 near one end of axle sleeve 10, and the pressing end on bearing gland 5 compresses
Rolling bearing 6 is fixed near one end of bearing housing 3.So that the pressure force stable equilibrium suffered by the side of rolling bearing 6, it is to avoid
The abrasion of rolling bearing 6 or axle sleeve 10 caused by weighting.In actual applications, the edge of back-up ring 11 can be pressed against the axis of rolling
6 whole side end face is held, the pressing end on bearing gland 5 is pressed on the centre position at the edge of back-up ring 11, that is, be pressed on the axis of rolling
Hold on the back-up ring 11 of 6 side end face middle positions.The effect for possessing fixation and sealing of back-up ring 11, bearing gland 5 is further served as
To fixed and sealing effect.
It is to reduce further to avoid abrasion between rolling bearing 6 and axle sleeve 10, it is necessary to periodically dose addition lubricating oil
Operation and wear and tear, can add between axle sleeve 10 and rolling bearing 6 can the oily device of slow release lubricant, in the present embodiment, can
Outside framework oil seal 4 is added between axle sleeve 10 and bearing housing 3, inside is added with lubricating oil, can automatically be sustained lubricating oil therein,
To provide necessary lubrication between axle sleeve 10 and rolling bearing 6.Outside framework oil seal 4 is arranged on the inner side of rolling bearing 6, the i.e. axis of rolling
6 towards the side for adding grey conveying worm main body are held, when sealing ring 12 is provided with, outside framework oil seal 4 sealing ring can be arranged on
12 inner side.To avoid oozing out leakage between gap of the lubricating oil between bearing housing 3 and axle sleeve 10, can be in bearing housing 3 and axle
Filler 9 is provided between set 10, filler 9 is flexible material, such as tetrafluoroethene, the absorbable lubricating oil for infiltrating.To cause
Filler 9 is replaceable, in the inner side of bearing housing 3, is left between axle sleeve 10 and is available for filler 9 to import and export, and sealed up by gland 7
Import and export.The section of gland 7 substantially L-type a, side of gland 7 extend into what is formed between bearing housing 3 and axle sleeve 10
In importing and exporting, so as to block the import and export, another side fixedly mounts with the inner side edge of bearing housing 3.Outside framework oil seal 4 and filler
9 settable multiples.Certain space is left between outside framework oil seal 4 and filler, so that bearing housing 3 can be in contact with axle sleeve 10.
When it is time for repair, remove fixing bolt between bearing gland 5 and bearing housing 3, between back-up ring 11 and tailing axle 8
Fixing bolt, so as to rolling bearing 6, sealing ring 12, reinforced seal 4 can be removed from axle sleeve 10；From opposite side, by filler pressure
Fixing bolt between lid 7 and bearing housing 3, so as to remove filler 9；Fixing bolt between bearing suspension 2 and housing 1 is torn open
Remove, bearing housing 3 is removed, and then axle sleeve 10 is removed from tailing axle 8, repaired accordingly, changed.
In sum, one kind that the present invention is provided adds grey conveying worm, compared with prior art, have the following advantages that：
1. outside framework oil seal is increased, for bearing provides rolling lubrication, it is to avoid abrasion；
2. sealed using filler and gland, it is ensured that lubricating oil is not lost in, it is ensured that corrosive medium does not flow into bearing housing,
Ensure that bearing long-term operation；
3. sliding bearing is changed to rolling bearing, it is to avoid the tailing axle that abrasion causes sinks；
4. bearing suspension is set to demountable structure, can not take out conveyor screw can just overhaul to the position；
5. maintenance cost is saved, maintenance difficulty is reduced again.
As described above, with reference to given plan content, similar technical scheme can be derived.In every case it is without departing from this
The content of inventive technique scheme, any simple modification made to above example according to technical spirit of the invention, equivalent change
Change and modify, still fall within the range of technical solution of the present invention.
