Abstract

trata-se de uma polia (1) com um pino aperfeiçoado, que compreende: um cubo (3) dentro do qual o anel externo (11) de um mancal de rolamento (12) é chaveado; um pino de sustentação giratório alojado dentro do anel interno (13) do mancal; labirintos de proteção alojados entre o pino e o cubo para a proteção do mancal; uma ranhura circunferente (6), que é circunferente com relação ao diâmetro externo da polia (1) na qual um revestimento conformado (7) é alojado para o contato com fio de diamante (8); o cubo da polia sendo fabricado em duas peças (9, 10) que são apertadas de maneira estável sobre o diâmetro interno da polia (1); além do mais, tem cada superfície externa (18) do cubo dotada de um labirinto anular (17) que se penetra mutuamente com um labirinto anular (16) presente sobre cada superfície interna de um pino desmontável (2) fabricado em duas peças (14, 15) e apertado em sentido axial por um elemento de ligação desprendível (19), e que tem a ligação entre o pino aperfeiçoado (2) e o suporte (20) da polia (1) efetuada por meio de elementos de aperto (26) e elementos de guia (25) inseridos em uma direção paralela ao plano de disposição da polia, na espessura das paredes (29, 30) do suporte propriamente dito. são aqui descritas modalidades vantajosas específicas de construção e montagem das peças do pino (2), de fixação do pino aperfeiçoado no suporte (20) e de configuração externa do pino (2), para facilitar o intertravamento entre as polias e os fios na máquina de vários fios para cortar blocos de pedra.It is a pulley (1) with an improved pin, comprising: a hub (3) into which the outer ring (11) of a bearing (12) is keyed; a rotating bearing pin housed within the bearing inner ring (13); protective mazes housed between pin and hub for bearing protection; a circumferential groove (6) which is circumferential with respect to the outer diameter of the pulley (1) in which a shaped liner (7) is housed for contact with diamond wire (8); the pulley hub being manufactured in two pieces (9, 10) which are stably tightened over the inner diameter of the pulley (1); Moreover, each outer surface (18) of the hub is provided with an annular labyrinth (17) which is mutually penetrable with an annular labyrinth (16) present on each inner surface of a detachable pin (2) made of two pieces (14). , 15) and axially tightened by a detachable connecting member (19), and having the connection between the improved pin (2) and the pulley support (20) effected by means of clamping elements (26). ) and guide elements (25) inserted in a direction parallel to the pulley arrangement plane at the thickness of the walls (29, 30) of the support itself. Specific advantages of construction and assembly of the pin (2) parts, improved pin fixing on the bracket (20) and external configuration of the pin (2) are described herein to facilitate interlocking between the pulleys and the wires in the machine. multi-threaded to cut stone blocks.
