Abstract

"CONSTRUçãO DIVIDIDA DE HASTE DE CONEXãO". Uma construção dividida de haste de conexão feita aplicando um tratamento de endurecimento de superfície em uma extremidade larga (1b) tendo um furo de pino de manivela (1d), dividindo a extremidade grande (1b) em uma haste (2) e uma tampa (3), e unindo a haste (2) e a tampa (3) uma na outra, com suas superfícies divididas colocadas juntas e apropriadamente posicionadas por um parafuso de engate, em que a superfície periférica internado furo de pino de manivela (1d) da extremidade grande (1b) é formada com um ponto de início de rompimento (5) , cujo comprimento axial (L1) é menor que o comprimento axial (L2) da superfície periférica interna.
