Abstract
The utility model provides a polyurethane wear-resistant floor roller comprising a supporting central axle, a bearing and a roller contacted with the steel rope, which is characterized in that the periphery of the supporting central axle (1) is provided with high wear-resistant polyurethane roller (3), the bearing (4) is embedded in the polyurethane roller, the inner ring of the bearing is matched with the supporting central axle and the outer ring of the bearing is matched with the back-off parts on both sides of the polyurethane roller, a sealing ring (2) is arranged at the outer side of the bearing and fixed with a claps (5). The utility model applies the polyurethane roller having high wear resistance, high elasticity, high pressure resistance and high stiffness, which greatly reduces the abrasion of the surface of the roller and the steel rope; the rolling bearing is directly positioned inside both ends of the roller and sealed with the plastic labyrinth sealing ring, which integrates the polyurethane roller, the bearing, the sealing ring and the supporting central axle to be a whole part in order to ensure the sealing and the rotary flexibility of the roller and make the floor roller passive to rotate the blade in order to minimize the wear, thereby prolonging the service life of the floor roller and the steel rope. The utility model is characterized in light overall weight, very convenient installation, maintenance and replacement and less noise.
Description
Technical field
The utility model relates to wear-resisting ground of the polyurethane roller that a kind of main slant, sub-inclined shaft, slope, ground track that is used for the mine draws steel cable.
Background technology
The ground roller material of mine conveying machinery use at present generally is metal, plastics and natural rubber.When the rope traction mine car moves, the ground roller is during as its carrying roller passive rotation, metal ground roller is comparatively serious to the wearing and tearing of steel rope, usually steel cable is only with just scrapping half a year, and metal ground roller was generally 3～4 months service life, metal ground roller weight is heavier in addition, the labour intensity when having increased maintain and replace, and noise is bigger during operation.The ground roller of plastics and natural rubber material is in when operation, the steel rope that do not wear and tear, but ground roller itself is worn easily and causes service life short (being generally 1～2 month), use cost height.In addition, the integrally-built factor of ground roller, the block bearing at two ends separates with ground roller body, causes bearing felt bad, has a strong impact on result of use to making roll body rotate dumb, shortens service life.
It is good that the purpose of this utility model provides a kind of resistance to abrasion, good airproof performance, and long service life, the main slant, sub-inclined shaft, slope, the ground track that are used for the mine draw wear-resisting ground of the polyurethane roller of steel cable.
The technical solution of the utility model is: wear-resisting ground of polyurethane roller comprises supporting axis, bearing and the roller that contacts with steel rope, the periphery that it is characterized in that supporting axis is the polyurethane roll of high abrasion, bearing embeds the two ends of polyurethane roll, bearing inner ring cooperates with the supporting axis, outside race cooperates with polyurethane roll two ends recess, outer end at bearing is provided with seal ring, and is fixed by snap ring.
Wear-resisting ground of polyurethane of the present utility model roller used have high-wearing feature, the polyurethane roll of high resiliency, high crushing resistance, high rigidity, the wearing and tearing of roller surface and the wearing and tearing of steel wire cable are significantly reduced; With the antifriction-bearing box inside, roll body two ends of directly packing into, with plastics labyrinth collar sealed bearings, make polyurethane roll, bearing, seal ring, supporting axis be assembled into one, guaranteed the rotation alerting ability of leak tightness and roll body, made the passive movable vane of passing on of ground roller, wearing and tearing are reduced to minimum, thereby improved the service life of ground roller and steel rope, its overall weight is light, installation, maintenance, changes very conveniently, and noise is low.
Description of drawings
Fig. 1 is the structural representation of wear-resisting ground of polyurethane of the present utility model roller.
Among the figure, 1-supports axis, 2-seal ring, 3-polyurethane roll, 4-bearing, 5-snap ring.
The specific embodiment
As shown in Figure 1, wear-resisting ground of polyurethane of the present utility model roller is by the polyurethane roll 3 of supporting axis 1, bearing 4 and high abrasion, seal ring 2 is formed, the periphery of supporting axis 1 is a polyurethane roll 3, bearing 4 embeds the two ends of polyurethane roll, and bearing inner ring cooperates with the supporting axis, and outside race cooperates with polyurethane roll two ends recess, seal ring 2 is in the outer end of bearing, and fixing by snap ring 5.It is contained on the easy shelf of tube and can uses.
