Coupling
A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.
The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By careful selection, installation and maintenance of couplings, substantial savings can be made ....etc

Flange couplings DIN 116
Flanged couplings of torsional rigidity, in particular,
Durable and reliable shaft connections which can
withstand the shocks and radially or axially acting loads.
The connected shafts must be precisely aligned.
Form C are equipped with flanged connections
deepening for axial washers in accordance with
DIN 28135. (used, for example, the vertical
agitator shafts). Thrust thrust washers not
in the scope of delivery and must be ordered separately.

Design and size recommendations

The goal in designing the flange coupling is designed to optimize the number and size of bolts for flange couplings and flange dimensions. The number of bolts must be at least six.
Soles-supergrip bolt designed for maximum voltage shift of 280 n/mm2 and a maximum axial voltage of 350 n/mm2.
Design of torque
Design of torque shall be determined in accordance with
TD = TN S .. (1)
The shock factor may be selected from the table.
Number of soles-Supergrip bolts
Start by assuming the size of the bolt, then deter ....etc

ABSTRACT

Mild steel or wrought iron shaft are available in lengths varying from 6 to 10 meters, so as to make them handy and easy to transport. More lengthy shafts cannot be manufactured in a correct form to be used for power transmission. In engineering practice shafts of large lengths are required to transmit the torque which can be obtained by joining two or more shafts in order to obtain the required length. The joining of shafts is done by device is called as coupling.Tyre c ....etc

Oldham Coupling

Oldham Coupling has three discs, one connected to the input, one associated with the output, and the average drive that connects to the first two on a thorn and a Groove. tongue and Groove on one side, perpendicular to the tongue and Groove on the other. Middle disc rotates around its Center at the same speed as the input and output shafts. Its Center traces of circular orbit, twice per revolution, around
midpoint between input and output shafts. Often springs are used to reduce the backlash mechanism. the advantage of this typ ....etc
