Abstract

Patente de Invenção:<B>"TAMPA DE MANCAL QUE PODE SER REPOSICIONADA PRECISAMENTE"<D>. Uma tampa do mancal (10,110, 210, 310, 410, 510) feita de metal em pó sinterizado possui formada de forma inteiriça saliências cónicas (40, 140, 240, 340, 440, 540) cercando seus furos de parafuso (26, 126, 226, 326, 426, 526) que se estendem dentro dos furos em sentido contrário (L) na estrutura do anteparo do mancal do motor (B) e produzem uma conformidade plástica entre as saliências (40, 140, 240, 340, 440, 540) e o anteparo (B) quando a saliência (40, 140, 240, 340, 440, 540) é assentada no furo em sentido contrário (L). A tampa do mancal (10, 110, 210, 310, 410, 510) pode então ser removida do anteparo (B) para instalação do eixo de comando e reinstalada na posição pré-fabricada idêntica. As saliências (40, 140, 240, 340, 440, 540) são afiladas uma vala (44, 144, 244, 344, 444, 544) cerca cada saliência (40, 140, 240, 340, 440, 540), e a saliência (40, 140, 240, 340, 440, 540) pode ser proporcionada com chavetas axiais (160, 460) e/ou ser oblonga (540) na direção axial. Os vazios (V1 até V4) podem também ser formadas nas superfícies planas dos apoios (T, 22, 522) que limitam-se com o anteparo (B).
