Power transmission is made through the cylindrical shaft end, fit k6 to EN 50347, with a
locking thread. Bearing life is calculated with 20.000 operating hours.
Radial force
If the motors drive via pinions or toothed belts, then high radial forces will occur. The
permissible values at the end of the shaft may be read from the diagrams in chapter
"Dimension Drawings" (➜ # 73). The maximum values at rated speed are listed in the
technical data. Power take-off from the middle of the free end of the shaft allows a 10%
increase in F .
R
Axial force
When assembling pinions or wheels to the axis and use of e.g. angular gearheads axial
forces arise. The permissible values at the end of the shaft may be read from the diagrams in
chapter "Dimension Drawings" (➜ # 73). The maximum values at rated speed are listed at
the technical data.
Coupling
Double-cone collets have proved to be ideal zero-backlash coupling devices, combined, if
required, with metal bellows couplings. For hygienic applications is recommended to use
food grade couplings. Customer is responsible for using suitable coupling on AKMH shaft
according application.
The standard version of each motor is fitted with an electrically isolated temperature sensor
(rated temperature 155°C ± 5%). The sensor does not provide any protection against short,
heavy overloading. The sensor is integrated into the monitoring system of the AKD.Motor is
equipped with thermal sensor, which contains KTY83-110 and PTC serially connected.
Setup of threshold limit in the drive to 2500 Ohms. Sensor is defined by following diagram:
