Cold Rolling Mills; Slitting Machine Drives; Frequently Asked Questions. What is the principle of a universal joint? A universal joint, also known as a U-joint, is a mechanical coupling that allows for the transmission of rotary motion between two shafts that are not in line with each other. The principle behind its operation involves using a ...

Through materials and tight tolerances, the universal joints have proven to reduce vibration levels in rolling mills. Universal joint design features include closed eye one-piece yokes, replaceable inner race bearing package, zero radial …
The Dresden Technical University carried out interviews with numerous rolling mill operators, which helped to confirm the above statements. The interviews were based on a questionnaire elaborating on the cost aspects related to a specific mill operation. Rolling mills in Asia and Europe and of different types (i.e. plate mills, hot strip mills
This fixed small alignment issues between the engine and rolling mill shafts, which previously hindered productivity. How are universal joints made? The most basic form of a universal joint consists of two shaft yokes perpendicular to each other, with a four-pointed cross-connecting yoke. The bearing cap assemblies, which contain the cross ...
the roll side joint is constrained in dimension by the minimum work roll diameter. When designing rolling mills, the work roll diameter needs to be kept as small as possible, because this reduces the rolling forces required. When revamping drivelines, very often only the motors and gears are increased whereas the work rolls remain unchanged.
way is a bore in the joint hub, into which the shaft is inserted and secured with a spring pin (or rolling pin). Alternatively, a keyway can be used to secure the shaft. A firm seat can also be achieved with square, hexagonal, splined, or threaded shaft ends. The choice of connection type depends primarily on the
At the time of mill roll replacement, the hydraulic pressure of the rigid coupling is released so the coupling will shrink for easy replacement work. Supported shaft diameter 30-720 mm Maximum transmission torque range 0.3-372 kN・m. …

In a rolling mill, upper and lower work rolls are connected with single motor by their respective universal spindle. The spindle allows upward and downward movement of work rolls by allowing its shaft to bend up to ~15 o angle. This bending is only possible by universal cross positioned at its both ends. One of the cross bearing located at ...
