A sample universal joint colour-coded to the diagrams about the equation of motion. The red and blue planes are visible. Angular (rotational) output shaft speed ω 2 {\displaystyle \omega _{2}\,} versus rotation angle γ 1 {\displaystyle \gamma _{1}\,} for different bend angles β {\displaystyle \beta \,} of the joint
Also, although universal joints are simple to produce and can withstand large forces, universal joints often become "notchy" and difficult to rotate as the angle of operation increases. The first type of constant-velocity joint was the Double Hooke's (Double Cardan) Joint which was invented by Robert Hooke in the 17th century. This design uses ...
A prop-shaft assembly consists of a propeller shaft, a slip joint and one or more universal joints. Where the engine and axles are separated from each other, as on four-wheel drive and rear-wheel drive vehicles, it is the propeller shaft that serves to transmit the drive force generated by the engine to the axles.
the cylindric joint consists of an RP or PR serial chain constructed so that the axes of the revolute and prismatic joints are parallel, the universal joint consists of an RR serial chain constructed such that the axes of the revolute joints intersect at a 90° angle;
The use of two universal joints, properly phased and with parallel alignment of the drive and driven shafts, allows the use of simple cross-type universals. In contrast, a torque tube arrangement uses only a single universal at the end of the transmission tailshaft, typically a constant velocity joint , and the axle housing is held fast by the ...
Repeated joints may be summarized by their number; so that joint notation for the SCARA robot can also be written 2RP for example. Joint notation for the parallel Gough-Stewart mechanism is 6-UPS or 6(UPS) indicating that it is composed of six identical serial limbs, each one composed of a universal U, active prismatic P and spherical S joint.
