drive torque, hydraulic load, crushing load is coming on the top roller. The forces acting on the mill rolls give rise to shearing, bending, torsion and compressive stresses. The top roller is most highly stressed, since it consumes about half of the mill torque.
Competitive gear couplings incorporate an Oring seal. In order to conform with today''s high misalignment capacities, this Oring must fit into a groove that is larger than the ring. WALDRON® couplings use a truly high misalignment seal that seals remarkably under misaligned conditions. WALDRON® Gear Couplings FULL ENGAGEMENT TEETH
According to the "Hill rolling force formula", taking particular account of the influence from horizontal vibration of rolled piece in roll gap, a dynamic rolling force model is analyzed. Considering the interaction between vibration of strip and roll, the dynamic vibration model of rolling mill is established. On this basis, the time delayed feedback is introduced to control the vibration

At the heart of the gear drive, gears turn in pairs, working together to transmit power to your appliion. Gear drives increase torque, reduce speed, and change direction of the rotating shaft. With so much relying on such a basic piece of equipment, it''s imperative to start with a gear drive you can count on.

Dec 31, 2015 · In the study of electromechanical coupling vibration of mill main drive system, the influence of electrical system on the mechanical transmission is considered generally, however the research for the mechanism of electromechanical interaction is lacked.
Considering the mixed friction on load side, the electromagnetic coupling torque provided by motor side and the external disturbance torque on load side, the dynamical equation of an electromechanical coupling drive system containing friction under external excitation can
Roll stand performance requirements for steel pipe production are very high. Pipe diameters of up to 1,800 mm are continually subjected to measurement and quality controls during the production process. The drive performance in this case lies in the high torque range.. Overload couplings with an automatic reengagement function are used between the transfer units and the rollers driven in the
A universal joint (universal coupling, Ujoint, Cardan joint, Spicer or Hardy Spicer joint, or Hooke''s joint) is a joint or coupling connecting rigid rods whose axes are inclined to each other, and is commonly used in shafts that transmit rotary motion.It consists of a pair of hinges loed close together, oriented at 90° to each other, connected by a cross shaft.
