Description
Technical field
the present invention relates to the improvement of drawing-frame rubber roll bearing block structure.
Background technology
in textile machine the effect of drawing frame be by 6 ~ 8 slivers in course of conveying, utilize roller and roller by the sliver disperseed each other and close and drawing-off, improve the uniformity of sliver and degree of stretching, the depth of parallelism of fiber, and the fiber of different quality is mixed in sliver evenly.After the drawing-off of roller and roller, sliver also will send into by guiding leather roller the curved catheter having boundling and guide effect concurrently, gathered by curved catheter (buncher) and send sliver, through the bell-mouthed cohesion of go-no-go and the compression of pressure roller, become tight poly-sliver, for necessary condition created by the one-tenth line obtaining good quality.
after sliver leaves the jaw of pressure roller, be imported in the curved inclined tube of circle bar dish, sliver holds to get rid of in bar cylinder at a high speed by circle bar dish in order; And drawing frame medium rubber roller high speed, round-the-clock running under the drive of roller, so need good lubrication guarantee.Rubber roll shaft holder structure in the market is not generally with sealing or seals cost higher.
Summary of the invention
the present invention is exactly for the problems referred to above, provides a kind of good sealing effect and the simple drawing-frame rubber roll bearing block structure of structure.
for achieving the above object, the present invention adopts following technical scheme, the present invention includes roller and bearing block, and roller two ends mandrel is placed in the bearing in bearing block, mandrel front end is provided with plug, and its structural feature mandrel rear portion is provided with the sealing ring preventing the lubricating oil in bearing from overflowing.
as a kind of preferred version, sealing ring of the present invention is O RunddichtringO.
as another kind of preferred version, plug of the present invention is positioned in bearing block by the back-up ring outside it.
as another kind of preferred version, plug medial surface of the present invention is provided with groove, is provided with spheroid in groove, end in contact before spheroid outer end and mandrel.
as another kind of preferred version, spheroid of the present invention is steel ball, and described bearing block adopts steel bearing block.
as another kind of preferred version, bearing of the present invention comprises two parts, is provided with spacer between two parts bearing.
as another kind of preferred version, core back-end of the present invention diameter is greater than the anterior diameter of mandrel, is ring-shaped depression between mandrel front portion and core back-end, and the anterior rear end of mandrel is round table-like annular protrusion, and described sealing ring is placed in ring-shaped depression.
as another kind of preferred version, core back-end of the present invention is circumferentially provided with bearing block positive stop lug boss corresponding to bearing block rear end.
secondly, core back-end of the present invention is circumferentially provided with the dust-proof outer shroud being formed with bearing block rear end and turn round gap structure corresponding to bearing block rear end.
in addition, bearing block rear end of the present invention is outer wall indent annulus joint, and longitudinal section, dust-proof outer shroud front end is the L shape structure corresponding with indent annulus joint.
beneficial effect of the present invention.
mandrel rear portion of the present invention is provided with the sealing ring preventing the lubricating oil in bearing from overflowing.Sealing ring effectively can prevent the spilling of the lubricating oil in bearing, and sealing, oil-containing is effective, greatly reduces maintenance time and the cost of roller bearing.
in addition, structure of the present invention is simple, processing cost is low, is convenient to promote the use of.
Accompanying drawing explanation
below in conjunction with the drawings and specific embodiments, the present invention will be further described.Scope is not only confined to the statement of following content.
fig. 1 is structural representation of the present invention.
fig. 2 is bearing block front-end architecture schematic diagram of the present invention.
fig. 3 is overall appearance figure of the present invention.
in figure, 1 be roller, 2 be dust-proof outer shroud, 3 be L shape structure, 4 be positive stop lug boss, 5 be indent annulus joint, 6 be ring-shaped depression, 7 be O RunddichtringO, 8 be annular protrusion, 9 be mandrel, 10 be bearing, 11 be spacer, 12 be bearing block, 13 be spheroid, 14 be groove, 15 for plug.
Detailed description of the invention
as shown in the figure, the present invention includes roller 1 and bearing block 12, roller 1 two ends mandrel 9 is placed in the bearing 10 in bearing block 12, and mandrel 9 front end is provided with plug 15, and mandrel 9 rear portion is provided with the sealing ring preventing the lubricating oil in bearing 10 from overflowing.
described sealing ring is O RunddichtringO 7.
described plug 15 is positioned in bearing block 12 by the back-up ring outside it.
described plug 15 medial surface is provided with groove 14, is provided with spheroid 13 in groove 14, end in contact before spheroid 13 outer end and mandrel 9.Effectively can be prevented the play of roller 1 right position by spheroid 13, and spheroid 13 outer end and mandrel 9 front end are point cantact, contact friction force is little.
described spheroid 13 is steel ball, and described bearing block 12 adopts steel bearing block.Steel bearing block can adopt tube material to make, and solves the problems such as existing profiled piece processing difficulties.
described bearing 10 comprises two parts, is provided with spacer 11 between two parts bearing 10.
described mandrel 9 rear end diameter is greater than the anterior diameter of mandrel 9, and be ring-shaped depression 6 between mandrel 9 front portion and mandrel 9 rear end, the anterior rear end of mandrel 9 is round table-like annular protrusion 8, and described sealing ring is placed in ring-shaped depression 6.
described mandrel 9 back end circumference is provided with bearing block 12 positive stop lug boss 4 corresponding to bearing block 12 rear end.Effectively spacing by positive stop lug boss 4 pairs of bearing blocks 12, ensure that bearing 10 can not come off from mandrel 9.
described mandrel 9 back end circumference is provided with corresponding to bearing block 12 rear end and forms with bearing block 12 rear end the dust-proof outer shroud 2 turning round gap structure.Due to drawing-frame rubber roll 1 work under bad environment, many dust and cotton willow catkins flying in the air; Bearing block 12 and roller 1 junction are designed to turn round gap structure, good dustproof effect; Play once oil spilling, the effect that fluid also can not throw away with the roller 1 of High Rotation Speed simultaneously.
described bearing block 12 rear end is outer wall indent annulus joint 5, and longitudinal section, dust-proof outer shroud 2 front end is the L shape structure 3 corresponding with indent annulus joint 5.
be understandable that, above about specific descriptions of the present invention, the technical scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
