Document Type and Number:
Japanese Patent JP6111599
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a joint cross type universal joint constructed to reduce torque loss while using a reduced number of components, and to hardly cause damage such as crack in each bearing cup 11c even when an excessive load is applied between a pair of yokes.SOLUTION: A recessed portion 21 is provided in the center of a front end face 20 of each shaft part 12a as part of a joint cross 9a, and a protruded portion 18a is formed on the inner face center of a bottom plate part 15c of each bearing cup 11a. The front end of each protruded portion 18a is made to elastically abut on the bottom face of each recessed portion 21, while restricting the dimension of a gap 22 existing between a portion near the outer diameter of an inner face 23 of each bottom plate part 15c and a portion near the outer diameter of the front end face 20 of each shaft part 12a. The dimension is such that the portions near the outer diameters of both faces 20, 23 do not contact each other during normal operation but the portions near the outer diameters of both faces 20, 23 contact each other when a great load is applied thereto.
