Capplings are used to commit a grinding shaft to a driven shaft. These are used. When the axis of the shaft are collinear, the axis of the shaft are intersecting and the axis of the shaft are parallel and the distance between them is related to small. Plagic coupling is a simplest and standard form of coupling used most extensively to transvid power from one shaft to other. The planche coupling is the assembly of the parts, the shaft one, the shaft two. The planche socket side, the planche, the speedod side, keys and nut and bolt. This shows the planche with the socket side and this is the planche with the speedod side. The shaft are usually made across the steel. The planche is made across the cast iron, the keys and the nut and bolt is made across the mine. The key is the shaft is placed in the flanges and the key is inserted into the slope and this is to reserve leading motion with the shaft and the flanges and these two pieces are placed together and it is fixed using the nut and bolt. So this is assembly of the planche coupling that is used to transvid power from a driving shaft to a driving shaft. Thank you for watching. Thank you.
