Hooke's joints or other joints with an equivalent intermediate member to which each coupling part is pivotally or slidably connected (F16D3/18, F16D3/20 take precedence)

Full Title

Yielding couplings, i.e. with means permitting movement between the connected parts during the drive (couplings disconnectable simply by axial movement F16D1/10; slip couplings F16D7/00) > Universal joints in which flexibility is produced by means of pivots or sliding or rolling connecting parts > Hooke's joints or other joints with an equivalent intermediate member to which each coupling part is pivotally or slidably connected (F16D3/18, F16D3/20 take precedence)

• F16D 3/265
• F16D 3/28 in which the interconnecting pivots include elastic members
• F16D 3/30 in which the coupling is specially adapted to constant velocity-ratio
• F16D 3/36 in which each pivot between the coupling parts and the intermediate member comprises a single ball
• F16D 3/38 with a single intermediate member with trunnions or bearings arranged on two axes perpendicular to one another (F16D3/36 takes precedence)
• F16D 3/44 the intermediate member being connected to the coupling parts by ridges, pins, balls, or the like guided in grooves or between cogs
