Abstract
The utility model discloses a kind of Novel dumbbell formula carrying roller, roller is made of middle circle shell of column roller, left side conical section roller, right side conical section roller three parts, and forms flute profile；Middle circle shell of column roller is fixed on the centre of axis by inner bearing unit, can be with respect to middle shaft rotation；Left side conical section roller and right side conical section roller are fixed on axis both ends by positioning screw, are rotated with axis with same angular velocity；Axis is fixed on conveying box body by outer shaft bearing assembly.The utility model middle circle shell of column roller can opposite sides conical section roller rotation, so as to avoid the opposite sliding friction of carrying roller middle circle shell of column and belt, extend the service life of carrying roller.
Description
Technical field
The utility model relates to belt conveyors, for idler structure among the belt conveyor of Bulk material.
Background technique
Belt conveyor since operating cost is low, versatility is widely used in well the conveying or transfer of every profession and trade material,
And carrying roller is most important component on belt conveyor.Have two currently used for carrying roller common on the belt conveyor of Bulk material
Kind: it is a kind of be three rollers press certain angle composition trough idler group, should structure is complicated, installation maintenance space is small, replacement support
Roller and bearing must open conveyer outer housing, and maintenance is inconvenient；Another kind is that middle circle shell of column and both ends conical section are welded
The trough idler formed together, the linear velocity of middle circle shell of column and both ends conical section is different when which rotates, two terminal circle
Bore that section linear velocity is fast, and middle circle shell of column linear velocity is slow, belt and carrying roller produce relative sliding friction, intermediate cylindrical when actual production
Section carrying roller serious wear, is easily damaged.
Summary of the invention
Utility model aims to solve the above problems, propose a kind of Novel dumbbell formula carrying roller, reduce carrying roller and skin
The opposite sliding friction of band, extends the service life of carrying roller.In order to solve the above problem the technical solution adopted is that: described is novel
Dumbbell-type idler is by middle circle shell of column roller, axis, left side conical section roller, right side conical section roller, positioning screw, inner shaft
It holds, sealing ring, end cap, screw, outer bearing carrier, outer bearing, hole card spring, screw composition.The middle circle shell of column roller is logical
The centre that inner bearing, sealing ring, end cap, screw are fixed on axis is crossed, it can be with axis relative rotation, the left side conical section rolling
Cylinder and right side conical section roller are fixed on axis both ends by positioning screw, with axis with the rotation of same angular velocity, axis two
End installation outer shaft bearing assembly, outer bearing carrier are connect by screw with conveyer container body of outer cover.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；It is as shown in the figure: middle circle shell of column roller (1), axis (2), left circles
It bores section roller (3), right side conical section roller (4), positioning screw (5), inner bearing (6), sealing ring (7), end cap (8), screw
(9), outer bearing carrier (10), outer bearing (11), circlip (12), screw B(13).
Specific embodiment
The utility model, including left side conical section roller (3), middle circle shell of column roller (1) and right side conical section roller (4)
And axis (2), middle circle shell of column roller (1) both ends are equipped with bearing box, bearing box installs inner bearing (6), sealing ring (7), leads to
Cross end cap (8), screw (9) is fixed on the intermediate shaft shoulder position of axis (2), sealing ring (7) prevents dust from entering inner bearing (6)
In；Left side conical section roller (3) and right side conical section roller (4) are fixed on the shaft shoulder at axis (2) both ends by positioning screw (5)
Position；Axis (2) both ends are connected by outer bearing (11) and circlip (12) with the outer bearing carrier (10) being fixed on conveying box body
It connects.
It is made of with the roller of belt contacts cylindrical section and both ends conical section three parts, middle circle shell of column roller (1) can be with
The conical section roller at opposite axis (2) and both ends generates rotary motion.
Claims (2)
1. a kind of Novel dumbbell formula carrying roller, including left side conical section roller (3), middle circle shell of column roller (1) and right side conical section
Roller (4) and axis (2), it is characterised in that: the middle circle shell of column roller (1) both ends are equipped with bearing box, the bearing box
Inner bearing (6), sealing ring (7) are installed, the intermediate shaft shoulder position of axis (2) is fixed on by end cap (8), screw (9)；The left side
Side conical section roller (3) and right side conical section roller (4) are fixed on the shaft shoulder position at axis (2) both ends by positioning screw (5)；
Axis (2) both ends are connected by outer bearing (11) and circlip (12) with the outer bearing carrier (10) being fixed on conveying box body
It connects.
2. Novel dumbbell formula carrying roller according to claim 1, it is characterised in that: with the rollers of belt contacts by cylindrical section and
Both ends conical section three parts composition, middle circle shell of column roller (1) can generate rotation with respect to axis (2) and the conical section roller at both ends
Transhipment is dynamic.
