1. Flange couplings (1) Ordinary flange couplings are connected by bolts with reamed holes, and are centered by bolts of reamed holes (corresponding to reamed bolts), and rely on the shear resistance of bolts to transfer Torque. 2. The flange coupling (2) is connected by ordinary bolts...
1. Before installation, first check whether the prime mover and the working machine are concentric, whether there are wrapping paper and bumps on the surfaces of the two shafts, whether there are debris in the inner holes of the two half couplings of the plum coupling, and whether the edges of the inner holes are There are bruises, if any, the shaft and half coupling should be cleaned up,...
First of all, the first point is to determine the form of the coupling according to the application (what driven equipment, what is it used for, and what are the requirements for the whole set of equipment?) according to the equipment. ...
Flange coupling is the most widely used rigid coupling, consisting of two half couplings and connecting bolts.There are two centering methods for flange couplings: one is to match the tenon on one half of the coupling with the groove on the other half of the coupling. ...
