SLIDING CONSTANT VELOCITY UNIVERSAL JOINT
Document Type and Number:
Japanese Patent JP2023032205
Kind Code:
A
Abstract:
To provide a sliding constant velocity universal joint having a new specification of DOJ for reducing sliding resistance, securing durability even at a high normal operation angle, and satisfying stable constant velocity.SOLUTION: In a sliding constant velocity universal joint 1 which includes: an outer joint member 2 provided with a plurality of linear track grooves 7; an inner joint member 3 provided with a plurality of linear track grooves 9; a plurality of torque transmission balls 4; and a cage 5 for housing the torque transmission balls 4 in pockets 5a, and in which a center of curvature O1 of a spherical outer peripheral surface 11 and a center of curvature O2 of a spherical inner peripheral surface 12 of the cage 5 are offset to opposite sides in an axial direction with respect to a joint center O, a spherical gap δ3 for enabling contact guide is formed between a spherical outer peripheral surface Rc2 of the inner joint member 3 and a spherical inner peripheral surface 12 of the cage 5, and a positive axial gap is formed between the pockets 5a of the cage 5 and the torque transmission balls 4.SELECTED DRAWING: Figure 5
