Description
Technical field
The utility model relates to conveyer (band) components, more particularly, to the bend pulley on conveyer.
Background technique
It is well known that conveyer is that a kind of conveying capacity is big, efficiency of transmission is high, and conveying is at low cost, and has free from dust, noise
It is low, not by the factors such as topography and geomorphology, climate and environment limited, it can be achieved that transmission device remote, being continuously conveyed for a long time.
Bend pulley is the components of an important key in conveyer, and service life and working effect are to be directly related to conveying
The efficiency of transmission and job costs of machine, the bend pulley of conventional conveyor is mostly using the setting casting glue in the steel tube surface of processing
Or viscose glue is as wearing layer, but wearability is not high in actual use for this casting glue or viscose glue bend pulley, roller uses
Service life is short, and roller needs frequently to exchange, and increases maintenance time, improves the job costs of conveyer, reduce conveyer
Efficiency of transmission.Conveyer bend pulley starts to be fabricated using bulk ceramics at present, although wearability improves, service life is prolonged
It is long, but bulk ceramics roller, first is that weight is big, transmission resistance is big, and electric power consumption is more, second is that processing and installation is more troublesome.?
Someone starts to be laid with ceramic lining plate on roll body surface, although roller wearability improves, weight is had dropped, liner plate and roll body table
The connection glue-line in face is easy to fall off, and liner plate is easy to loosen, then is that liner plate and belt contacts face skid resistance be not high, and belt holds meaning and beats
It is sliding, or even will cause the safety accidents such as belt derailing.
Utility model content
Converyor roller in the prior art there are aiming at the problem that, the utility model provides a kind of not only intensity and wear-resisting
Property high, long service life, and the whole wear-resistant ceramic bend pulley that job costs are low, transmission efficiency is high.
The technical problems to be solved in the utility model is adopted the technical scheme that: the entirety wear-resistant ceramic bend pulley
It is equipped on a conveyor, it includes shaft, the boss plate for being fixed on both ends of the shaft and the wearproof roller being sleeved on boss plate, institute
It states and is arranged at intervals with several chop frame bodies in shaft, the support rod for the steel that every chop frame body is at least radially distributed by three
At support rod one end is fixed in shaft, cementing layer is filled between durable mill roller and shaft, the cementing layer is along axial
It is provided with and makes a concession hole, the wearproof roller is fired with high alumina ceramic material at high temperature, and wearproof roller passes through cementing layer and shaft
It is formed whole.
The cementing layer is by adhesive and silica sand or steel sand and other auxiliary materials are mixing cured forms, and the adhesive is cement
Adhesive, sulphur graphite adhesive, epoxy resin binder or electric smelting calcium aluminate cements.
High alumina ceramic material of the wearproof roller by alumina content in 40-50% is made.Wearproof roller compression strength exists
200MPa or more, for Mohs' hardness at 7 grades or more, thermal stability is high, and acid-alkali-corrosive-resisting is strong.
Further, axial keyway (figure is respectively provided on the wearproof roller inner surface and shaft outer surface
In be not drawn into), keyway cross sections are square, arc-shaped or triangle etc..
The utility model is compared with prior art:
1, high mechanical strength, corrosion resistance is strong, is unlikely to deform, and mechanical wear is small, service life at 10 years or more,
2, machine driving is steadily reliable, and transmission efficiency is high,
3, manufacture is easy for installation, and job costs are lower.
Detailed description of the invention
Fig. 1 is that the utility model cuts open structural schematic diagram,
Fig. 2 is the A-A schematic cross-sectional view of Fig. 2.
1, shaft 2, wearproof roller 3, yielding hole 4, support rod 5, cementing layer 6, boss plate 7, bearing in the figure
8, sealing ring 9, bearing block 10, bearing cap.
Specific embodiment
In fig. 1 and 2, the whole wear-resistant ceramic bend pulley is fitted on conveyer (band), it includes steel
Shaft 1, the boss plate 6 for being fixed on both ends of the shaft and the wearproof roller 2 being sleeved on boss plate are arranged at intervals in the shaft
Four chop frame bodies, every chop frame body are at least formed by the support rod 4 of three radially-arranged steel, (the how many rows of specific setting, often
How many of row's setting, every diameter according to the length of roller and of different sizes can carry out comprehensive setting), support rod
One end is fixed in shaft, the other end is in contact close to wearproof roller surface of internal cavity, or preferably with wearproof roller inner surface, described
Both ends of the shaft is fitted with bearing assembly, and the bearing assembly includes bearing 7, bearing block 9 and bearing cap 10, bearing block and shaft it
Between be equipped with sealing ring 8, filled with cementing layer 5 between durable mill roller and shaft, the cementing layer is axially disposed yielding
Hole 3, the wearproof roller are fired with high alumina ceramic material at high temperature, are first carried out wearproof roller and shaft, are arranged in shaft
Good skeleton body welds one piece of boss plate and shaft, then that wearproof roller and shaft is upright, is poured with adhesive from upper end
It fills, and opens up and make a concession hole, make adhesive in setting expansion and contraction, do not generate bulging and cracking, after being fully cured, then will be another
One piece of boss plate welded seal, to make wearproof roller and shaft form entirety by cementing layer.
Embodiment of above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although referring to specific embodiment
The utility model is described in detail, those skilled in the art should understand that, it can be to the skill of the utility model
Art scheme is modified or replaced equivalently, and without departing from the spirit and scope of the technical scheme of the present invention, should all be covered
