Simple taper bush couplings that tolerate no misalignment. Suitable for many simple applications.
Rigid couplings consist of 2 fully machined cast iron flanges (male and female design) which are mounted onto the shaft by means of taper lock bushes and which are held together by bolts.
The male half can accept the taper lock bush from the hub side (design H) or the flange side (design F). The female half is always machined to design F. This HF or FF couplings can be specified – a decision based simply on ease of access during assembly.
Note: Vertical shafts must always use FF design only
Easy to inspect visually and replace without effort.
Rigid couplings do not allow for misalignment. Torque rating dependent on the slip torque of the taper bush. Speed should be limited to 33 m/s (rim speed).
Generally suitable for applications using mild steel shafting.
