(OP)
With gear type flexible couplings would you expect the gear teeth on both the hubs and outer sleeve be hardened?

RE: Gear Type Flexible Couplings
Suprises me, as being used to compensate for angular mis-alignment which must result in almost point contact, I was expecting them to be hardened to some degree.
RE: Gear Type Flexible Couplings
"All external teeth are surface hardened and ground with slight crowning ..... the internal teeth are shaped into the through hardened components. In order to avoid distortion, no further heat treatment is normally applied. If necessary, the internally toothed parts can be nitrided, in which case care must be taken to minimize distortion."
However, this is top of the line Swiss stuff, not El Cheapo. You get what you pay for.
However, they also say "One exception is that of the couplings for high torque at low speed, such as are used in the cement industry. Here the external teeth are not surface hardened."
RE: Gear Type Flexible Couplings
Gear couplings transmit more torque per unit diameter than any other coupling type, the limiting factors for gear selection are usually shaft or keyway capability/performance.
Enjoy...
