A range of torsionally couplings are available from the extensive couplings range at sai. The backlash free couplings offer power transmission with torsional vabration damping, advantages of this couplings are that they have axial plug-in, are easy to assemble , are maintenance free and have compensation of shaft misalignment- axial , radial and angular.
The universal coupling is a kind of shaft coupling that permits large angle displacement between the shafts, specially used for connecting shafts in that condition. The compact design of radial external dimension ensures convenient maintenance, large transmitting torque, high efficiency, long service life and low noise during working. Driving of intersecting shafts can be delivered. The large designed shaft angle can be altered during its running and the maximum shaft angle can reach 35 degrees. When a single universal coupling is used, the speed of driven shaft will fluctuate periodically. And this is mainly used for the transmission connecting of the intersecting shafts. Due to such features as large deviation angle and transmitting torque, the universal couplings are widely applied in Metallurgical machinery, steel rolling machinery, mining machinery, textile machinery, paper machinery, cement machinery, hoisting and conveying machinery, petroleum machinery, electrical machinery, chemical machinery, shipbuilding,etc. various conditions of universal machinery and heavy machinery.
A flexible coupling connects two shafts, end-to-end in the same line, for two main purposes. The first is to transmit power (torque) from one shaft to the other, causing both to rotate in unison, at the same RPM. The second is to compensate for minor amounts of misalignment and random movement between the two shafts
