Servo Planetary Gearbox-EP

Overview

Ever-Power S-1FT7 motor with mounted EP+ series planetary gearbox

Ever-Power S-1FT7 motors can be combined with planetary gearboxes to form compact coaxial drive units. The gearboxes are flanged directly to the drive end of the motors.

When selecting the gearbox, ensure that its maximum permissible input speed is not exceeded by the maximum speed of the motor. In the case of high operating frequencies, allowance must be made for the factor f2 (see Configuration Manual, Ever-Power S-1FT7 synchronous motors). The frictional losses of the gearbox must always be taken into account when engineering geared drives.

The gearboxes are only available in non-balanced design.

Benefits

High efficiency

1-stage: > 97 %

2-stage: > 94 %

Minimum torsional backlash

1-stage: ≤ 4 arcmin

2-stage: ≤ 6 arcmin

Power transmission from the central sun wheel via planet wheels

No shaft deflections in the planet wheel set due to symmetrical force distribution

Very low moment of inertia and thus short acceleration times of the motors

Output shaft bearings dimensioned for high cantilever and axial loads with preloaded tapered-roller bearings

The gearboxes are connected to the motor shaft via an integrated clamping hub. A plain motor shaft extension is necessary for this purpose. Shaft and flange accuracy tolerance N in accordance with DIN 42955 and vibration severity grade A in accordance with EN 60034-14 are sufficient. The motor flange is adapted by means of adapter plates.

Output shaft of gearbox exactly coaxial with the motor

The gearboxes are enclosed (seal between gearbox and motor) and filled with oil at the factory. They are lubricated and sealed for their service life. The gearboxes are suitable for all mounting positions.

Degree of protection of gearbox: IP65

Small dimensions

Low weight
