Abstract
The utility model discloses a support roller sealing device and aims to provide a support roller sealing device with better dustproof and waterproof effects, simple structure and easy disassembly and maintenance. The support roller sealing device comprises a bearing seat and a sealing cover, and is characterized in that a boss and a radial slot are arranged in the center of the outer end surface of the bearing seat, and outer seal rings and an inner seal ring are arranged on the end surface of the sealing cover and are all integrated with the sealing cover, wherein the outer seal rings and the end surface of the bearing seat form labyrinth seal, the inner seal ring and the end surface of the boss form lip-mouth contact seal, and the sealing cover is in interference fit with a central shaft. The support roller sealing device is mainly used for a support roller of a belt conveyer.
Description
Technical field
The utility model relates to a kind of seal arrangement, more particularly, relates to a kind of carrying roller seal arrangement.
Background technique
Carrying roller is the critical piece of belt conveyor, and consumption is huge, and it damages is that water, ash, gas etc. arrive bearing because sealing effect is bad mostly, makes bearing rust, burn into stuck, and transit telegram is useless to cause carrying roller.Existing carrying roller, sealing technique is the labyrinth seal of adopting tradition single mostly, complex structure.Labyrinth seal is a kind of clearance seal, and its gap is bigger, reaches 1mm, water, ash, air-capacitor easily enter bearing by seal clearance, make bearing corrosion, corruption, stuck, thereby carrying roller was lost efficacy, and black box is many, even there is special tool also to be difficult to dismounting and maintenance.Cost is also high.
Summary of the invention
The purpose of this utility model is to provide a kind of improved carrying roller seal arrangement, to overcome above-mentioned shortcoming.
Technical solution of the present utility model is formed seal arrangement by bearing support exterior edge face and sealing cover.There are boss and radial groove in center portion, bearing support exterior edge face, and outer seal ring and inner seal ring are arranged on the end face of sealing cover, and sealing cover is made with rubber, and interior boring ratio support roller shaft footpath is little.So directly banding need not to locate jump ring on axle, and 2 outer seal rings and bearing support end face form the first road labyrinth seal, and the end face of 1 inner seal ring and boss forms the second road lip contact seal.The first road labyrinth seal can stop entering of most of dust, water, and dust, the water by the sealing of first road is blocked before the second road lip contact seal fully on a small quantity.
The utility model comprises bearing support and sealing cover, it is characterized in that: the center portion, exterior edge face of described bearing support 1, boss 2 and radial groove 3 are arranged, on the end face of described sealing cover 4, outer seal ring 5,5 ' and inner seal ring 6 is arranged, all seal rings all constitute an integral body with sealing cover 4, wherein, outer seal ring 5,5 ' form labyrinth seals with the end face 7 of bearing support 1, inner seal ring 6 forms lip contact seal with the end face of boss 2, and sealing cover 4 is interference fit with central shaft 8.
Described sealing cover 4 is sealing covers of making of rubber.
The utility model has the advantages that: most dust and water have been blocked in the first road labyrinth seal, and dust by labyrinth seal and water are blocked fully in second road lip contact seal place on a small quantity, thereby good sealing effect, the life-span is long, and is simple in structure, sealed member significantly reduces, and cost reduces.And sealing cover makes of rubber, can need not the jump ring location, so tool free just can be dismantled very convenient maintenance by the interference banding on axle.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: the 1-bearing support, the 2-boss, the 3-radial groove, the 4-sealing cover, 5,5 '-outer seal ring, 6-inner seal ring, 7-bearing support end face, 8-central shaft.
Embodiment
Below in conjunction with accompanying drawing the utility model and embodiment thereof are described in further detail.
Referring to accompanying drawing, the utility model comprises bearing support and sealing cover, it is characterized in that: there are boss 2 and radial groove 3 in the center portion, exterior edge face of described bearing support 1, on the end face of described sealing cover 4, outer seal ring 5,5 ' and inner seal ring 6 is arranged, all seal rings all constitute an integral body with sealing cover 4, wherein, outer seal ring 5,5 ' with the end face 7 formation labyrinth seals of bearing support 1, inner seal ring 6 forms lip contact seal with the end face of boss 2, and sealing cover 4 is interference fit with central shaft 8.
Described sealing cover 4 is sealing covers of making of rubber.
Key technology of the present utility model is outer seal ring 5,5 ' and the inner seal ring 6 on sealing cover 4 end faces, outer seal ring 5,5 ' form labyrinth seals wherein with the end face 7 of bearing support 1, inner seal ring 6 then forms lip contact seal with the end face of boss 2, like this, the utility model just combines the labyrinth seal in first road and the lip contact seal in second road, thereby broken through traditional single labyrinth seal, cause sealing perfect inadequately drawback, water, ash, gas can be blocked in outside the two seals up hill and dale can not enter bearing.
Claims (2)
1, a kind of carrying roller seal arrangement, comprise bearing support and sealing cover, it is characterized in that: the center portion, exterior edge face of described bearing support (1), boss (2) and radial groove (3) are arranged, on the end face of described sealing cover (4), outer seal ring (5,5 ') and inner seal ring (6) are arranged, all seal rings all constitute an integral body with sealing cover (4), wherein, outer seal ring (5,5 ') forms labyrinth seal with the end face (7) of bearing support (1), inner seal ring (6) forms lip contact seal with the end face of boss (2), and sealing cover (4) is interference fit with central shaft (8).
