IMPACT MECHANISM, IMPACT DEVICE, CAGE MEMBER, AND STRESS DAMAGE REDUCING METHOD IN CAGE MEMBER OF IMPACT MECHANISM

摘要

PROBLEM TO BE SOLVED: To prevent the damage to a cage member by an impact. SOLUTION: A cage member 100 is composed of an anvil end plate 102 where through holes 118 and 120 are formed; a spline end plate 104 where nonthrough holes 122 and 124 are formed; and columns 106 and 108 respectively formed with longitudinal direction grooves 114 and 116 to connect the anvil end plate 102 and the spline end plate 104. The nonthrough holes 122 and 124 which are the portions to support hammer pins 28 and 30 do not penetrate the spline end plate 104, in order to secure their strength.
