Patent ID: 8297420

Claim:
A method for manufacturing an overrunning clutch including a tubular clutch outer with a plurality of tapered notch portions formed circumferentially on an inner circumferential portion, a clutch inner having a cylindrical portion disposed at a first end, said cylindrical portion being inserted into said inner circumferential portion of said clutch outer such that wedge-shaped spaces are formed between an outer circumference of said cylindrical portion and said notch portions, rollers mounted into said wedge-shaped spaces so as to be movable circumferentially, springs that press said rollers toward narrow ends of said wedge-shaped spaces, and stopping portions that are disposed on said inner circumferential portion of said clutch outer so as to project inward at narrow end positions of each of said wedge-shaped spaces, wherein a driving force is transmitted from said clutch outer through said rollers to said clutch inner by unidirectional rotation, said method comprising: installing said rollers and said springs in each of said notch portions of said clutch outer; measuring an inscribed circle diameter of said rollers at two or more positions that differ in an axial direction of said rollers in a state in which said rollers are respectively placed in contact with said stopping portions by pressure from said springs; and determining an outside diameter of said cylindrical portion from a measured value of said inscribed circle diameter such that an amount of roller bite is at a predetermined amount at a position at which said rollers come into contact with said stopping portions.
