The clamp-type rigid coupling uses two axially divided shells, which are clamped by bolts to realize the connection between the two shafts. join.
The clamp type rigid coupling does not need to move axially when assembling and disassembling, so it is very convenient to assemble and disassemble. The disadvantage is that the centering accuracy of the two shafts is low, the structure and shape are relatively complex, and the manufacturing and balance accuracy is low. It is only suitable for In the case of low speed and stable load, usually the maximum outer edge line speed is not more than 5m/s, when the line speed exceeds 5m/s, balance check is required.
In order to improve the balance, the bolts should be installed in positive and inverted phases. Collet couplings do not have axial, radial and angular compensation properties.
The characteristics of the vertical clamp type rigid coupling are similar to those of the clamp type rigid coupling. In occasions, it should be used for the connection of vertical shafts such as agitators.
