摘要： A rotary assembly comprising in combination a drive member which is rotatable about an axis and a driven member which is rotatable by the drive member about said axis by means of a balanced threepoint kinematic support, wherein the support consists of three parts each consisting of a ridged projection on one of the members and a complementary notched region in the other member, two of the said notched regions are disposed on a circle centred on the said axis and the third notched region is directed radially with respect to the said axis.
