Vis\u00e3o geral do produto<\/h3>\n

O rolamento autocompensador de rolos axial de dupla dire\u00e7\u00e3o \u00e9 um rolamento para servi\u00e7o pesado que pode suportar cargas axiais bidireccionais e tem uma fun\u00e7\u00e3o de auto-alinhamento autom\u00e1tico. A sua estrutura central consiste em dois conjuntos de an\u00e9is de eixo, an\u00e9is de assento e duas filas de rolos de tambor. Com a pista esf\u00e9rica do anel exterior, pode absorver eficazmente o desvio de centragem entre o eixo e o assento do rolamento (o erro de \u00e2ngulo permitido \u00e9 normalmente de 2\u00b0~3\u00b0).<\/p>\n

Perguntas e respostas t\u00e9cnicas comuns<\/h2>\n

Q1: Como selecionar os rolamentos axiais de rolos esf\u00e9ricos de dupla dire\u00e7\u00e3o?
\n\u2192 Este rolamento \u00e9 adequado para cenas com maior carga axial, velocidade m\u00e9dia e baixa, e requer fun\u00e7\u00e3o de auto-alinhamento<\/p>\n

Q2: Quais s\u00e3o as consequ\u00eancias de exceder o \u00e2ngulo de auto-alinhamento?
\n\u2192 Um desvio superior a 3\u00b0 provoca um aumento da tens\u00e3o na extremidade do rolo, reduzindo significativamente a vida \u00fatil.<\/p>\n

Q3: Como monitorizar o estado da lubrifica\u00e7\u00e3o?
\n\u2192 Atrav\u00e9s da temperatura (recomendado <80 \u2103) e monitoramento de som anormal, a lubrifica\u00e7\u00e3o com \u00f3leo \u00e9 preferida em ambientes de carga pesada e alta temperatura<\/p>\n

Q4: Pontos-chave para a instala\u00e7\u00e3o?
\n\u2192 O anel de eixo\/anel de assento deve estar bem encaixado, sendo proibida uma pr\u00e9-carga excessiva<\/p>\n

Q5: Quais s\u00e3o as formas t\u00edpicas de falha?
\n\u2192 Os principais modos de falha incluem danos na pista causados por lubrifica\u00e7\u00e3o deficiente e danos na gaiola causados por funcionamento em \u00e2ngulo excessivo<\/p>\n
