Abstract
REVESTIMENTO EM POLIURETANO ANTI-CHAMA PARA ROLOS OU ROLETES DE TRANSPORTADORES DE CORREIA. Refere-se a patente invenção a um rolo composto por um eixo (1), que compreende uma carcaça metálica (2), um mancal metálico usinado (3) que aloja rolamentos, ainda, pelo rolo possuir um revestimento em poliuretano antichama (4) dissipador de energia de impacto. Não obstante, compreende uma vedação topo labirinto (5) e vedação tipo retentor (6) reterem contaminantes ou umidade, sendo fixados no mancal metálico usinado (3). Possuindo, ainda, um rolamento (7) fixado no mancal metálico usinado (3) e fixado por meio de um anel elástico (8). O pelo anel elástico (8) mantém o rolamento na posição pré-determinada dentro do mancal metálico usinado (3), além de ser fixado ao mancal metálico usinado (3) e/ou ao eixo (1). Desta forma, rolos ou roletes de transportadores de correia, sejam rolos de impacto, retorno, carga, virados, alinhador ou tensor, são utilizados nos transportadores de correria e aplicados ao longo de toda a extensão do transportador, cuja função é permitir o deslizamento da correria sobre o transportador, possibilitando o transporte do material. O presente revestimento é aplicado na parte externa da carcaça do rolo, tendo o objetivo de proteger a carcaça contra o desgaste provocado pelo atrito entre a correia e o rolo.FLAME-RESISTANT POLYURETHANE COATING FOR BELT CONVEYOR ROLLERS OR ROLLERS. The patent invention refers to a roller composed of an axle (1), which comprises a metal housing (2), a machined metal bearing (3) that houses bearings, further, because the roller has a flame-retardant polyurethane coating (4) impact energy sink. However, it comprises a labyrinth top seal (5) and retainer type seal (6) to retain contaminants or moisture, being fixed to the machined metallic bearing (3). It also has a bearing (7) fixed to the machined metallic bearing (3) and fixed by means of an elastic ring (8). The elastic ring (8) keeps the bearing in the predetermined position inside the machined metallic bearing (3), in addition to being fixed to the machined metallic bearing (3) and/or to the shaft (1). In this way, rollers or rollers of belt conveyors, whether impact, return, load, turned, aligner or tensioner rollers, are used in belt conveyors and applied along the entire length of the conveyor, whose function is to allow the sliding of the would run over the conveyor, enabling the material to be transported. The present coating is applied to the outside of the roller housing, with the aim of protecting the housing against wear caused by friction between the belt and the roller.
