Abstract
The utility model relates to a composite polyurethane carrier roller for a belt conveyor, which comprises a pipe, a shaft, a bearing, composite materials, a baffle and a retainer ring. A labyrinth seal ring is arranged outside the bearing. The upper plane and the lower plane of the bearing are in close contact with the inner wall of the pipe. A seal disc is arranged outside the labyrinth seal ring. The retainer ring is arranged outside the labyrinth seal ring to form the external seal structure of the labyrinth seal ring. A seal ring is arranged in the bearing and is supported by a backing plate. Compared with the prior art, the utility model has the advantages that multiple seal structures are arranged, the external water, dust and other impurities cannot enter the bearing, the effects ofthe water prevention, the dust prevention and the corrosion protection are good, the service life of the carrier roller is greatly improved, the structure is reasonable, the abrasive resistance is good and the shock resistance is strong.
Description
Technical field
The utility model relates to a kind of carrying roller that is used for adhesive tape conveyor.
Background technology
Adhesive tape conveyor is mainly used in the metallurgy industry, is used for conveying solid substance or granular material, also can be used for other technical field.Carrying roller is the major part in the adhesive tape conveyor, also is consumable accessory.At present, the carrying roller in the adhesive tape conveyor, the sealing at its axle head position is difficult to reach waterproof and dustproof, corrosion prevention, and people are also in waterproof and dustproof, the anti-corrosion problem of research carrying roller axle head, but still have defective, influence the normal operation of sealing-tape machine.
So, improve the sealing effectiveness of position, sealing-tape machine roller carrier shaft end, make that it is wear-resisting, corrosion prevention, shock resistance, be the problem that presses for solution at present.
Summary of the invention
The purpose of this utility model provides a kind of good airproof performance, corrosion stability travelling apron composite polyurethane carrying roller strong, high-elastic, good impact resistance, and its long service life has reduced the production run cost.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of travelling apron composite polyurethane carrying roller comprises pipe, axle, bearing, composite material, baffle plate, back-up ring, is provided with the labyrinth seal circle in the outside of bearing, lower plane and tube wall closed contact on it, and labyrinth seal circle outside is provided with seal disc.
Described labyrinth seal circle is made of inner seal ring and exterior seal ring, the last lower plane of inner seal ring and exterior seal ring respectively with the tube wall closed contact.
The outside of described labyrinth seal circle is provided with back-up ring, constitutes the exterior hermetically-sealed construction of labyrinth seal circle.
Described back-up ring comprises inner shield ring, outer back-up ring, and inner shield ring, outer back-up ring constitute the exterior hermetically-sealed construction of labyrinth seal circle.
Described bearing inside is provided with seal ring.
Described bearing in-to-in seal ring supports by backing plate.
The mode of described composite material by adopting integral die-cast moulding is attached to reaching both ends of the surface above the pipe.
Compared with prior art, the utility model has the advantages that:
1) this device is provided with multiple-sealed structure, and the exterior water of bearing, dust and other foreign material can not be entered in the bearing, and waterproof and dustproof, anticorrosion ability are good, the service life of having improved carrying roller greatly;
2) rational in infrastructure, wear resisting property is good, and shock resistance is strong.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
See Fig. 1, a kind of travelling apron composite polyurethane carrying roller, comprise pipe 1, axle 2, backing plate 3, seal ring 4, bearing 5, composite material 6, inner seal ring 7, exterior seal ring 8, inner shield ring 9, outer back-up ring 10, baffle plate 11, back-up ring 12, seal disc 13, be provided with the labyrinth seal circle in the outside of bearing 5, the labyrinth seal circle is made of inner seal ring 7 and exterior seal ring 8, the last lower plane of inner seal ring 7 and exterior seal ring 8 respectively with pipe 1 inwall closed contact, labyrinth seal circle outside is provided with seal disc 13.
Outside at the labyrinth seal circle is provided with back-up ring, and back-up ring is made of inner shield ring 9 and outer back-up ring 10, and inner shield ring 9, outer back-up ring 10 constitute the exterior hermetically-sealed construction of labyrinth seal circle.
The outside of outer back-up ring 10 is provided with baffle plate 11, and baffle plate 11 outsides are provided with back-up ring 12.
Also be provided with seal ring 4 in bearing 5 inside, seal ring 4 supports by backing plate 3.
The manufacturing process of this device is: pipe 1, axle 2, backing plate 3, seal ring 4, bearing 5 are installed in the pipe both ends, pipe 1 is fixed on the axle 2 by bearing 5, install inner seal ring 7, exterior seal ring 8 additional in the bearing outside, and in the gap of inner seal ring 7 and exterior seal ring 8, annotate lubricating oil, with metal inner shield ring 9 that inner seal ring 7 and exterior seal ring 8 is fixing, and in cavity, fill lubricating oil, and then with the outer back-up ring 10 of metal with metal inner shield ring 9 and further sealing of axle 1, place baffle plate 11 at last, outside back-up ring 12 is installed.Adopt the die casting mode with the outside of composite material again, make all parts become as a whole attached to pipe 1.Compound polyurethane material adopts the mode of integral die-cast moulding attached to reaching both ends of the surface above the pipe, can reach sealing effectiveness more effectively.
