Abstract
The utility model relates to a compositely sealed supporting roller of belt conveyor, which comprises a bearing bracket, a mine-dedicated bearing, a roller skin, an outer retainer ring, a roll shaft, a middle gasket ring, an outer gasket ring, an outer waterproof rubber ring, an inner gasket ring and a steel wire snap ring; wherein the roller skin is arranged on the roll shaft through the supporting and turning element, and both ends of the roller skin are provided with roller skin fringe-retracted mouths. The bearing bracket is arranged through the center of both ends of the roller skin in a form of inward retracting, the mine-dedicated bearing is arranged in the bearing bracket, and the steel wire snap ring is arranged on the roll shaft of the corresponding mine-dedicated bearing. The outer gasket ring and the middle gasket ring are arranged in the outer retainer ring, the outer waterproof rubber ring is further provided to work with the outer gasket ring, and the inner gasket ring is arranged in the outer gasket ring. The bearing bracket is integrated with the roller skin, the mine-dedicated bearing is arranged in the bearing bracket, and a double sealing device used for dust prevention is arranged on the end plane of the bearing bracket. A bilateral labyrinth seal form is adopted in the space formed by the roll shaft, the mine-dedicated bearing and the bearing bracket. The utility model has advantages of strong sealability, rational structure and long service life, and can be extensively used in various belt conveyers.
Description
Technical field:
The utility model relates to mechanical transmission device, relates in particular to belt feeder compound seal carrying roller.
Background technology:
The transmission machinery that uses mostly is belt conveyer at present, and this machinery in use common faults is that conveyer carrying roller is bad because of sealing property, and causing is in operation need change carrying roller in large quantities.This not only causes a large amount of consumes, and use cost strengthens, and will shut down replacing, influences work efficiency.The conveyer carrying roller of prior art mainly contains two kinds of seal form, and a kind of is labyrinth seal, because the seal ring of this sealing means is gapped, so its water resistance is poor.Another kind is a contact-type seal, and the carrying roller long-term use of this seal form is easy to wear, and dust very easily enters.So generally speaking, there are defectives such as carrying roller weak point in service life in the carrying roller of prior art because the defective in the sealing causes waterproof and anti-dust performance poor.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of belt feeder compound seal carrying roller is provided, and adopts the structure of double containment, has to seal tight, water resistance advantage strong and rational in infrastructure.
Belt feeder compound seal carrying roller described in the utility model, including bearing seat, Mine bearing, roller skin, outer back-up ring, roll shaft, middle seal ring, exterior seal ring, outer waterproof apron, inner seal ring and steel wire snap ring forms, roll shaft is the center support of belt feeder compound seal carrying roller described in the utility model, and the roller skin is arranged on the roll shaft by support and tumbler.In order not make carrying roller that belt conveyor is caused scuffing, on the two ends of roller skin, all be provided with the edge reducing of roller skin.At the center, two ends of roller skin, be provided with bearing seat with the interior form that contracts, be provided with Mine bearing in the bearing seat, in order to guarantee the stability of Mine bearing, on the roll shaft of corresponding Mine bearing, be provided with the steel wire snap ring.In the outermost end of said roller skin,, be provided with outer back-up ring with the basic form concordant with the outer face of roller skin.Be provided with exterior seal ring and middle seal ring in the outer back-up ring, cooperate exterior seal ring also to be provided with outer waterproof apron, in exterior seal ring, be provided with inner seal ring.Bearing seat and roller skin connect as one, and Mine bearing is arranged in the bearing seat, and the end face of bearing seat is provided with the double seal of dustproof usefulness.In the space that roll shaft, Mine bearing and bearing seat form, be set to bilateral labyrinth sealed form, compare with the one-sided labyrinth seal of prior art, strengthened the length in labyrinth.Be provided with middle seal ring, exterior seal ring and outer waterproof apron in the outer back-up ring, contact closely, formed Composite Double leak free structure with the labyrinth type inner seal ring.Said outer back-up ring, middle seal ring, exterior seal ring, outer waterproof apron and inner seal ring and bearing seat rotate around roll shaft together.
Belt feeder compound seal carrying roller described in the utility model is provided with the edge reducing of roller skin at roller skin section, has avoided carrying roller section right angle to scratch adhesive tape, the service life of having improved adhesive tape.The utility model is provided with exterior seal ring, inner seal ring and outer waterproof apron, can stop water, dust to enter in the carrying roller effectively.The utility model sealing property is strong, and is rational in infrastructure, and long service life can be widely used in various band conveyors, has excellent popularization and is worth.
