Abstract
A sleeve bearing for a split-angle connecting rod having a bearing surface including two opposed portions wherein the first portion is concentric with the journaled member during the loaded portion of a revolution and is defined by a constant radius which closely approximates the radius of the journaled member to provide a relatively small clearance with the journaled member and the second portion is eccentric with respect to the journaled member and is defined by at least one radius to provide a greater clearance with the journaled member.
Claims22
A sleeve bearing (20) having an outer cylindrical surface (24) and an inner bearing surface for surrounding a cylindrical journaled member (26) in close spaced relationship therewith in a manner defining a clearance space with the journaled member (26) to receive lubricant, said inner bearing surface having two opposed portions (A) and (B) wherein the first portion (A) is concentric with the journaled member (26) during the loaded portion of a revolution and is defined by a constant radius (r) which closely approximates the radius of the journaled member (26) to provide a relatively small clearance with the journaled member (26) and the second portion (B) is eccentric with respect to the journaled member (26) and is defined by at least one radius to provide a greater clearance with the journaled member (26).
A sleeve bearing half-shell (22) having an outer cylindrical surface (24) and an inner bearing surface for engaging a journaled member (26), said bearing surface extending 180.degree. and consisting of a first portion (A) beginning at one parting face and extending circumferentially on a first constant radius (r) for a part of the 180.degree. and a second portion (B) generated about a single eccentric point (34,34') beginning at the other parting face and extending circumferentially outside said constant radius (r) for the remainder of the 180.degree. and joining said first portion (A) on (28) said constant radius (r).
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), fastening means (18) for securing said housings (14;
- 16) together to define a circular bearing pocket, each of said housings (14;
- 16) providing one-half of the circular circumference of said pocket, said housings (14;
- 16) mating on a diameter which is disposed on an acute angle relative to said longitudinal axis of said rod (12), a sleeve bearing (20) disposed in said pocket, said sleeve bearing (20) having an outer cylindrical surface (24) engaging said pocket and an inner bearing surface for surrounding a cylindrical journaled member (26) in close spaced relationship therewith in a manner defining a clearance space with the journaled member (26) to receive lubricant, said bearing surface having two opposed portions (A) and (B) wherein the first portion (A) is concentric with the journaled member (26) during the loaded portion of a revolution and the second portion (B) is eccentric with respect to the journaled member (26), said first portion (A) extending circumferentially between spaced ends (28) on a constant radius (r) which closely approximately the radius of the journaled member (26) to provide a relatively small clearance with the journaled member (26) and said second portion (B) extending circumferentially outside said constant radius (r) and joining said first portion (A) at said spaced ends (28) on said constant radius (r), said sleeve bearing (20) comprising two half-shells (22), with each of said half-shells (22) including one-half of each of said first (A) and second (B) portions, one of said half-shells (22) being disposed in one bearing housing (14) with the other half-shell (22) disposed in the other bearing housing (16).
