The performance features of the two-speed gearbox for SIMOTICS M-1PH8 asynchronous motors are as follows:

Drive power up to 100 kW (134 hp)

Constant power range at drive shaft up to 1:24

Suitable for both directions of rotation

Motor shaft heights SH 100 to SH 225

Types IM B35 and IM V15 (IM V35 available on request)

The following advantages are gained by mounting the gearbox outside the spindle box:

Easy adaptation to the machine tool

Low noise and no temperature fluctuations due to gearing inside the headstock

Separate lubrication systems for the main spindle (grease) and the change-speed gearbox (oil)

Gear efficiency > 95 %

The drive power can also be transferred from the gearbox output via a gear wheel (on request) or coaxially via a flexible coupling rather than by a V-belt.

Gearboxes increase the drive torque at low motor speeds and extend the range of constant power that the main spindle motor can deliver. The full cutting capacity of modern machine tools can therefore be utilized throughout the entire speed range.

The two-speed gearboxes have a planetary design. The power is distributed among several planet wheels from the central sun gear. Thanks to this gearing design, the gearboxes are extremely compact. The gear-changing device, a splined sleeve that moves axially, is of form-fit design.

Position 1: Gear ratio i1 = 4
Position 2: Gear ratio i2 = 1

The motor is flanged onto the gearbox by an adapter plate. The three-phase motor must be suitably prepared for gearbox mounting.

With shaft height SH 160 and above, motors in frame sizes IM B35 and IM V15 must be supported at the NDE to eliminate any mechanical stress.

Any transverse force imported into the gearbox has to be borne by the gearbox and transmitted to the machine base.

The motors for all 2K gearboxes must be full-key balanced with a feather key. The 2K 120, 2K 250, 2K 300, 2K 450 gearboxes are sealed so that the motor flange is also adequately sealed in the standard version.
Vertical mounting positions IM V15 and IM V35 require circulating lubrication of the gearboxes.

The standard version of the change-speed gearboxes up to and including the 2K 300 has a maximum circumferential backlash of 30 angular minutes (measured at the gear output). Several special versions suitable for milling or machining with cut interruption can be supplied on request:

Reduced backlash with special features: max. 20'

Reduced backlash for high performance: max. 15'

Profile of a planetary gearbox

The power unit (motor and gearbox) is supplied with vibration magnitude grade R in accordance with EN 60034-14 (IEC 60034-14). This is also the case when the motor is ordered with vibration magnitude grade S.

The belt pulley1) must be a cup wheel type pulley. For mounting the pulley, the output shaft on the gearbox has a flange with an external centering spigot and tapped holes. for easy fitting and removal of the pulley.
