Abstract
"MANCAL DE CAVILHA DE PISTãO PARA MOTORES DE COMBUSTãO". A presente invenção refere-se a um mancal de cavilha de pistão para motor de combustão no qual está montado uma cavilha de pistão (8), deve ser oferecido um formato de perfuração de cavilha aperfeiçoado em comparação com o estado da técnica, afim de ser lograda uma redução nítida de tensões mecânicas do pistão e conseq³entemente um prolongamento da durabilidade do pistão. Além disso, pela perfilação deve ser evitado uma formação de ruído no mancal da cavilha de pistão. De acordo com a invenção, isto é logrado pelo fato de que a face lateral (5) da perfuração de cubo (2) ao longo de todo seu eixo de cubo na região do Equador de cubo - zênite de cubo - Equador de cubo apresenta formato oval elevado, acompanhando a representação de parâmetro da sessão oval X = b/2 X cos <244>}; y= a/2 x sin <244>} para 0<198> <243> <244> <243> 180<198> sendo que, na região de Equador de cubo - nadir de cubo - Equador de cubo é configurado em formato circular cilíndrico formando com a: diâmetro oval grande; b = D: diâmetro oval pequeno; D: diâmetro da sessão de cubo cilíndrica; a.: ângulo que forma um raio aleatório contra o eixo Z.
