UNIVERSAL JOINT Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed universal joint contains two coupling members with axle-shafts, each provided with grooves with fitted-in balls. Coupling members are made in form of yoke. Intermediate member is introduced additionally. Said member consists of four interconnected disks coupled in pairs with yoke of corresponding coupling member. Slot made in each disk passes from center of disk and coincides in direction with slot of corresponding yoke of coupling remember. Yokes of coupling members and disks connected with yokes are arranged so that intermediate member is ball-like. Coupling of disks with corresponding yokes of coupling members is provided through balls placed in grooves made in yokes of coupling member and disks connected with corresponding coupling members. EFFECT: improved reliability in operation. 2 cl, 5 dwg
