Robert Hooke is commonly thought of as the inventor of Hooke''s joint or the universal joint. However, it is shown that this flexible coupling (based on a fourarmed cross pivoted between semicircular yokes attached to two shafts) was in fact known long before Hooke''s time but was always assumed to give an output exactly matching that of the input shaft.
Drive shafts are classified into two types: block drive shafts and round drive shafts according to the structure of the cross amp; bearings used for the universal joint. Features and representative structures of each type are shown below. ~ indicates the judgment standard torque for the maximum torque (maximum under normal conditions).
wobbling of the transmission shaft which leads to frequent breakdown of the rolling mill causing production loss. To find out the various stresses and strains we perform static structural analysis on the universal joint in ANSYS Workbench. The material of the joint is structural steel (SAE 4340), the properties of which are given in table 2.

As a result, your universal joint shaft is operationally reliable and has a long lifetime. Voith universal joint shafts ensure productivity and reduce maintenance costs for your machine or system. If necessary, the design layout of our universal joint shafts can be adapted to your drive and operating conditions.
#0183;#32;A Universal coupling is a special type of coupling in which misalignment of shafts is allowed. Shafts are free to move any direction in order to transmit torque or power from one shaft to another. In this project work a Universal coupling was designed, in
#0183;#32;Universal joint shafts are mostly utilized in large rolling mills as they are well suited for the angularity requirements of reversing rougher mill applications. Also, universal joint shafts are balanced dynamically in the 2 planes. This reduces noise emissions and helps the machine to run smoothly over longer spans. Universal joint shafts are made up of various components including a flange yoke,
In fact, theory of linkage based CV joint is developed as early as 1973 ( Hunt). In practice, many innovative designs are already seen in such CV joints as Koenigs and Thompson CV joint. It would be a good idea to consider analysis and design (in terms of both mechanics and kinematics) of such CV joints in modern CV joint textbooks.

Through materials and tight tolerances, the universal joints have proven to reduce vibration levels in rolling mills. Universal joint design features include closed eye onepiece yokes, replaceable inner race bearing package, zero radial clearance bearing package and builtin spring packs on the roll end knuckle.
As a result, your universal joint shaft is operationally reliable and has a long lifetime. Voith universal joint shafts ensure productivity and reduce maintenance costs for your machine or system. If necessary, the design layout of our universal joint shafts can be adapted to your drive and operating conditions.
Shaft Sizing Stress Analysis In design it is usually possible to locate the critical areas, size these to meet the strength requirements, and then size the rest of the shaft to meet the requirements of the shaftsupported elements.

Lowmaintenance cardan shaft universal joint shafts reliably transmit torques of up to 600,000 Nm in the steel factory. Our cardan shafts, with swing diameters ranging from 90 to 435 mm transmit mechanical drive power in steel rolling mill plant.
The performance of the rolling mill depends on the Universal joint shaft through which the power is transmitted to the rollers of a mill. This paper mainly focuses on the modal analysis of universal joint shaft for rolling mills because this shaft is subjected to vibrations caused due to the jerk produced during the passing of billet through the rollers.
#0183;#32;Design of a rolling mill is a complex task requiring thorough understanding of the process as well as good decisionmaking capability for satisfying various conflicting goals. Numerous investigations have been carried out for the analysis of the rolling to two working rolls by means of universal joints and telpic shafts.
The NucorYamato Steel Company in Arkansas, USA, is installing three Voith highperformance universal joint shafts of type CHT as part of the modernisation and optimisation of one of their rolling mills that is used for medium steels and heavy profiles. These shafts transmit torque from the motor to the rollers and are based on []
