Description

Fan's formula carrying roller in a kind of

Technical field

The utility model relates to a kind of carrying roller, relates in particular to a kind of interior fan's formula carrying roller for carrying bulk material to match with belt conveyor and use such as mine, metallurgy and chemical enterprise that is used for, and belongs to the conveying machinery field.

Background technology

Existing conveying machinery carrying roller for carrying bulk material to use, its planform thousand appearances ten thousand attitudes are being brought into play effect separately.Because most of carrying roller is made (being the steel carrying roller) with steel, structurally there is the sealing property defective in the steel carrying roller, can not protect bearing effectively and has shortened service life of bearing, causes whole carrying roller short service life; Remove this, the steel carrying roller also often scratches the scratch belt, and it is frequent that belt conveyor is changed; The steel carrying roller is because quality is heavy, withstanding corrosion and can not commonly promoting not.ZL02224351.8 " close-coupled combination carrying roller " was arranged before the utility model, it is with the carrying roller of waste and old rubber tyre through processing, and is used with belt conveyor to reach certain effect, though can turn waste into wealth, environment protecting is arranged, but service life, weak point was fatal weakness.And for example ZL200920063772.4 " change incline V-type carrying roller group ", ZL200920063773.9 " change incline flute profile carrying roller group " are the hard goods carrying roller, their good effects that matches with belt in material conveying process.

Summary of the invention

Task to be solved in the utility model provides a kind of easy to process, good sealing effect, long service life, withstand corrosion, rotational resistance is little, not scratch scratches belt and light weight interior fan's formula carrying roller.

For finishing above-mentioned task, the scheme that the utility model adopts is: it comprises roll body 1, embedded bearing seat 2, axle 3, bearing 4, labyrinth seal circle 5, stop bit circle 6 and cushion block 7 described a kind of interior fan's formula carrying roller.Symmetry is equipped with bearing 4 on the roll neck at axle 3 two, adjacent bearing 4 symmetry on the roll neck at axle 3 two is equipped with labyrinth seal circle 5, adjacent labyrinth seal circle 5 symmetry on the roll neck at axle 3 two is equipped with stop bit circle 6, in the periphery of stop bit circle 6 screens ring 61 is arranged.One end of labyrinth seal circle 5 is processed with the second annular arrangement grease trough 51, and the other end of labyrinth seal circle 5 is processed with boss 52.Be inlaid with quantity more than or equal to 1 cushion block 7 in the periphery of 2 one of embedded bearing seats, the inner of embedded bearing seat 2 is processed with the first annular arrangement grease trough 21, and the inwall of embedded bearing seat 2 outer ends is processed with screens groove 22 and taper scrobicular ring 23.Embedded bearing seat 2 is assembled to the periphery of bearing 4, labyrinth seal circle 5 and stop bit circle 6 from two symmetry of axle 3, and embedded bearing seat 2 is assemblied in the inner chamber at roll body 1 two together with cushion block 7 symmetries.

Adopt in a kind of that as above technical scheme provides fan's formula carrying roller compared with prior art, technique effect is:

1. low cost of manufacture, good sealing effect, water proof and dust proof effectively;

2. withstanding corrosion, light weight can improve 3～5 times service life;

3. not scratch scratches belt, can prolong the replacement cycle of belt, reduces operating cost;

4. rotational resistance is little, and energy-saving effect is obvious.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

As shown in Figure 1, described a kind of interior fan's formula carrying roller comprises roll body 1, embedded bearing seat 2, axle 3, bearing 4, labyrinth seal circle 5, stop bit circle 6 and cushion block 7, its axis 3 usefulness metallic materials are made, bearing 4 can be selected ball bearing for use, and roll body 1, embedded bearing seat 2, labyrinth seal circle 5, stop bit circle 6 and cushion block 7 can select for use High molecular material to make, characteristics such as High molecular material has that forming work is convenient, wear-resisting, friction coefficient is low, withstanding corrosion and light weight.

Symmetry is equipped with bearing 4 on the axle journal at axle 3 two, adjacent bearing 4 symmetry on the axle journal at axle 3 two is equipped with labyrinth seal circle 5, the inner ring of its centre bearer 4 is a close fit with axle cooperating between 3, labyrinth seal circle 5 also is not close fit with axle cooperating between 3, like this between the bearing 4 and spools 3, can not produce relative motion between the labyrinth seal circle 5 and spools 3.Adjacent labyrinth seal circle 5 symmetry on the roll neck at axle 3 two is furnished with stop bit circle 6, stop bit circle 6 is a close fit with axle cooperating between 3, periphery at stop bit circle 6 has screens ring 61, and the screens groove 22 on screens ring 61 and the embedded bearing seat 2 is closely cooperated.

As shown in Figure 1, 2, 3, be inlaid with quantity more than or equal to 1 cushion block 7 in the periphery of 2 one of embedded bearing seats, cushion block 7 can be evenly or non-uniform Distribution in the neighboring of embedded bearing seat 2, cushion block 7 on the embedded bearing seat 2 has the L section, the cross-sectional plane appearance of L section is the ring profile of tooth, and the middle-end position is L ₁Section, L ₁The cross-sectional plane appearance of section is conical.The embedded bearing seat 2 that is inlaid with cushion block 7 is assemblied in the periphery of bearing 4, labyrinth seal circle 5 and stop bit circle 6 from two symmetry of axle 3, embedded like this bearing seat 2 is with fan's formula cavity in forming between labyrinth seal circle 5, the stop bit circle 6, in this, in fan's formula cavity grease is arranged, described grease can be selected from butter etc., and stop bit circle 6 can prevent that grease is excessive.Make during assembling and be close fit between the outer ring of bearing 4 and embedded bearing seat 2 inwalls.Be processed with the first annular arrangement grease trough 21 in the inner of embedded bearing seat 2, can inject grease, outer end inner wall at embedded bearing seat 2 is processed with screens groove 22, and the screens ring 61 on it and the stop bit circle 6 matches, and on embedded bearing seat 2 taper scrobicular ring 23 is arranged.End at labyrinth seal circle 5 is processed with the first annular arrangement grease trough 51, grease can be injected wherein, and lubricate, and be processed with concave station 52 at the other end of labyrinth seal circle 5, concave station 52 can be fitted with the inner ring of bearing 4, seals.Embedded bearing seat 2 is assemblied in the inner chamber at roll body 1 two together with cushion block 7 symmetries, formed described in fan's formula carrying roller.
