UNIVERSAL JOINTS basic principles Constant velocity output can be restored by using a double joint or by connecting two single joints back to back. Two rules must be observed: Universal joints (U/J's) transmit rotation from one shaft placed end to end with another. They will operate at a much larger angle than is permissible with a misalignment coupler and are commonly used in pairs to take a drive train through laterally displaced axes. The ability to change angle while operating under load gives U/J's a further advantage and in these applications, a telescopic drive shaft is used to...

UNIVERSAL JOINTS application Universal joints are typically used to transmit positive rotation through intentional offsets where the power source is some way from the load. It is important to note that a U/J is essentially a pivot and that it cannot accommodate any parallel displacement between shafts if used singly. Moreover, the installation must allow for some adjustment when mounting the joint so that the shaft centre lines can be made to converge at the fulcrum of the joint. This is essential if the joint is to function correctly and not impose excessive radial loads on adjacent...

STEEL UNIVERSAL JOINTS features type TR, needle roller bearings – 6000 rpm max Huco universal joints feature a comprehensive range of sizes manufactured in good quality steels. Plain bearing and needle roller types are available and either can be supplied with square, hexagonal or keywayed bores to order. The joints are also manufactured with quick release collars and in telescopic form to order. This series is intended for applications demanding high rotational speeds (up to 6000 rpm) and large working angles where operation is without benefit of periodic lubrication. types TL & TS, plain...

PERFORMANCE DATA (T SERIES) types TL & TS, plain bearings – 1200 rpm max – 200 rpm for sizes 60-100 The nomogram charts the maximum dynamic moment for each size of joint. The curves represent the limit of performance and must not be exceeded, however momentarily, by peak impulse loads. The product of speed of rotation x working angle is given for values from 250–12000. The upper speed limit for this series is 1200 rpm and this corresponds to a maximum working angle of 10° at this speed. Working angles up to 45° are practicable provided the corresponding speeds are held within the limits of...
