CARDAN JOINT Russian patent published in 2002 - IPC

FIELD: rolling equipment, possibly torque transfer in rolling mills with high dynamic loads. SUBSTANCE: Cardan joint includes crosspiece and fork joined with pins through rolling bodies such as rollers. Rollers are mounted along pin by several rows; pins have axial turnings whose diameters are reduced towards bottom parts of pins. Wall thickness in plane of distant end of remote roller relative to crosspiece center consists 0.1-0.2 of pin diameter and in plane between two ends of two adjacent rollers in mean zone of pin length consists 1.1-1.4 of thickness of pin wall in plane of distant end of remote roller. Axial thrust bearing is arranged in bottom of turning and it rests upon fork body through tie rod. EFFECT: increased area of contact surface of rollers with surface of crosspiece pins, enhanced uniformity of redistributing load on bearing assembly along pin. 2 cl
