NORD gearmotors and gearboxes are available in several configurations for industrial
power transmission applications. The product range includes helical gear units,
parallel shaft gear units, bevel gear units, helical worm gear units and worm gear
units. Selecting the right NORD gearbox or NORD geared motor depends on motor power,
output torque, gear ratio, mounting position and shaft configuration.
NORD helical gear units provide efficient power transmission for a wide range of
industrial applications. NORD parallel shaft gear units are suitable for applications
requiring high torque and a compact parallel shaft arrangement. NORD bevel gear units
offer high efficiency and flexible mounting options, while NORD worm gear units provide
a compact solution for lower-power speed reduction applications.
A complete NORD gearmotor combines a suitable NORD gearbox with an electric motor
according to the required power, speed, torque and transmission ratio. We can assist
with NORD motor, NORD gearbox and NORD geared motor selection based on your application
requirements.
Above is the comprehensive table of NORD Geared motor, covering Helical (H series) and Bevel-helical (B series) types.
It provides detailed Nominal Torque Class T2N and Ratio ranges (i) for sizes 03 up to 14.
When selecting a NORD gearmotor or NORD gearbox with an adapter-mounted input shaft,
the permissible radial force FR1 and axial force FA1 are important
mechanical design parameters. The following data provides reference values according
to the input power P1 for selected NORD gear units.
This technical information is useful when a NORD motor or geared motor is connected
to external transmission components such as pulleys, sprockets, belts or chains.
The actual permissible shaft load depends on the complete NORD gearbox configuration,
operating speed, mounting arrangement and application conditions.
The radial force FR1 and axial force FA1 values should be evaluated
together with the corresponding input power when selecting a NORD gearmotor. These
parameters are especially relevant for applications involving belts, chains, pulleys,
sprockets and other external loads on the gearbox input shaft.
For NORD motor and gearbox selection, please provide the required motor power, input
speed, output speed or gear ratio, shaft load, mounting arrangement and application
conditions. This information allows the appropriate NORD geared motor configuration
to be evaluated for your application.
Technical note: The values presented above are provided as a technical
reference based on the supplied NORD documentation. The final permissible shaft load
must be verified against the applicable NORD technical documentation and the exact
gearbox configuration.
Above is the comprehensive mounting positions chart of NORD Geared motor, covering horizontal and vertical installation setups for heavy duty solutions.
