ESTRUTURA DE JUNTA DE ROTULA HEMISFERICA

摘要

A knuckle or swivel joint of the half-ball and socket type comprising a stud terminating in an enlarged diameter half-ball member disposed in the socket member and having a recess in which is engaged a biasing insert member made of resilient or elastomeric material placed under compression during assembly of the joint. The joint bearing surfaces are elastically pre-loaded in an appropriate direction which causes firm engagement of the bearing surfaces in mutual engagement and thus preventing play and rattling of the joint and compensating for wear.
