TWIN ARTICULATED COUPLING Russian patent published in 2000 - IPC

FIELD: not disengageable couplings; twin articulated couplings. SUBSTANCE: twin articulated coupling consists of two members with teeth at the ends and intermediate member with teeth at the ends mounted for engagement with coupling members. Teeth of intermediate member and coupling members have involute profile. Intermediate member is made from metal. Coupling is provided with protective sleeve rigidly connected with one coupling member. Other coupling member is mounted in protective sleeve at spaced relation for motion. EFFECT: possibility of transmitting torque with no distortion in shape at high efficiency; enhanced reliability; reduced usage of metal; reduced overall dimensions. 4 cl, 4 dwg
