For example, improvements in Sleeve Bearing for internal combustion engines in cooperation with ciguenales and Cranks

摘要

A split-angle end rod assembly [10] comprising an elongated rod [12] having a longitudinal axis and integral with an upper bearing housing [14]. A separate lower bearing housing [16] is included and bolts [18] secure the two bearing housings [14, 16] together to define a circular bearing pocket. The housings [14, 16] mate on a diameter which is disposed at an acute angle relative to the longitudinal axis of the rod [12]. A sleeve bearing [20] is disposed in the pocket and includes an inner bearing surface [28] surrounding a cylindrical journalled member [26] in close spaced relationship therewith. The bearing surface [28] has a first portion [A] extending circumferentially on a constant radius [r] and a second portion [B] extending throughout the remaining circumference but being disposed outside the constant radius [r] of the first portion [A] and joins the first portion [A] on the constant radius [r] thereof.
