Connecting rod module

A connecting rod module (1) includes: a connecting rod (10), which is formed of a sintered metal; and bearing raceway rings (outer rings (21, 31)), which are press-fitted into a through-hole (11a, 12a), respectively. The connecting rod (10) has a Young's modulus of from 120 GPa or more to 180 G...

Zusammenfassung:	A connecting rod module (1) includes: a connecting rod (10), which is formed of a sintered metal; and bearing raceway rings (outer rings (21, 31)), which are press-fitted into a through-hole (11a, 12a), respectively. The connecting rod (10) has a Young's modulus of from 120 GPa or more to 180 GPa or less. The outer rings (21, 31) each have a Young's modulus of from more than 180 GPa to 240 GPa or less. When T represents a radial thickness of each of the outer rings (21, 31), D represents an inner diameter dimension of each of the through-holes (11a, 12a), and I represents an interference between the outer ring (21) and a peripheral wall of the through-hole (11a) or between the outer ring (31) and a peripheral wall of the through-hole (12a), the following equations are established: T=(0.05¼0.15)×D; and I=(0.0004¼0.004)×D.
