| Mounting of Rotary Encoders for Separate Shaft Coupling | ||||||||||||
| Rotary
encoders of the ROD/ROC/ ROQ 400 series have an integral
bearing capable of withstanding up to 60 N (radially at shaft end)
at speeds up to 6000 rpm. They can therefore be connected directly
to mechanical transfer elements such as gears or friction wheels. Should the load exceed these values, HEIDENHAIN recommends the use of a shaft coupling. If high shaft loads are expected, for example when using belt gears or sprockets, HEIDENHAIN recommends mounting the ERN/ECN/EQN 400 with the bearing assembly. The coupling compensates axial motion and misalignment (radial and angular offset) between encoder shaft and drive shaft to prevent additional, external loads that would otherwise shorten the service life of the encoder bearing. The HEIDENHAIN product program includes diaphragm couplings and metal bellows couplings for rotor connection of the ROD/ROC/ROQ rotary encoders. |
