Key features of ABM shaft mounted helical gear motors
Design of flange mounted helical gear guarantees
• High efficiency
• Torsion-free housing
• Alloy, case hardened steel gears
• Quiet operation
Admissible radial forces Fr [N] and axial forces Fa [N] on FGA 53 to FGA 1354
Admissible radial forces of bearing support for hollow shafts have been based on the nominal life expectancy for normal duty cycle operations according to DIN ISO 281. Fr is dependent on output torque T2 [Nm], output speed n2 [RPM] and lever distance x [mm]. The calculation applies to the least favourable force vector angle and does not relate to direction of rotation. Fr is applied to the non-motor side.
The calculation of Fr is only valid if n2 > 9 RPM.
If only axial forces or simultaneous radial and axial forces are present, please consult with ABM.

End shield designs of shaft mounted helical gear motors
The illustration shows the standard execution. The mounting positions shown also apply to shafts with flanges and normal shaft executions.
Notes to terminal box location and wire entry point:
The terminal box is shown in location A 1 (and will be delivered in this location unless otherwise specified).
Terminal box locations B, C and D per customer request. The wire entry point can be rotated in increments of 90°.
Example of junction box and cable plug position
The oil relief plug is always on the bottom in relation to the gearbox mounting position.
