1) Descripción del engranaje de circunferencia
Como componente estructural y mecánico principal, la corona dentada en un tambor giratorio tiene efectos generalizados
cuando se le permite usar.
Como resultado, el desgaste de los engranajes debe abordarse de inmediato, generalmente mediante el reemplazo,
aunque en casos de desgaste inicial, los ajustes simples pueden evitar daños mayores.
2) Tratamiento térmico de corona dentada
Los engranajes se templan por llama o por inducción para lograr una dureza deseable.
Dureza de la circunferencia y el piñón engranajes juega un papel esencial en la maximización de la vida útil del equipo.
3) Material del engranaje de circunferencia
Fundición Acero/ ZG 42CrMo (AISI 4140) o ZG40CrNiMo (AISI 4340)
