1PH7/1PH4 servomotors with 2-speed gearboxes (asynchronous)

1PH7/1PH4 servomotors with 2-speed gearboxes (asynchronous)
Особенности

The performance characteristics of the two-speed gearboxes for 1PH7/1PH4 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 of construction IM B35 and IM V15 (IM V35 available on request)

Mounting the change-speed gearbox outside the headstock of the machine tool has the following advantages:

  • 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)
  • Gearbox efficiency > 95 %
  • Instead of V belts, the drive power can also be transmitted from the gear output by a gear wheel (available on request) or coaxially by means of a flexible coupling.
Область применения

Change-speed gearboxes increase the drive torque at low motor speeds and expand the range of constant power output available from the main spindle motor. The full cutting capacity of modern machine tools can therefore be utilized throughout the entire speed range.

Дизайн

Profile of a planetary gearbox

The two-speed gearboxes have a planetary design. The central sun wheel distributes the power to several planet wheels which revolve around it. The outstanding advantage of this design is its compactness. 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 flange-mounted onto the change-speed gearbox using an adapter plate. The AC motor must be suitably prepared for mounting.

For shaft heights of SH 160 and higher, motors of types of construction IM B35 and IM V15 must be supported free from stress on the non-drive end.

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 fitted key. The 2K 120, 2K 250, 2K 300 gearboxes are enclosed, so that the motor flange is adequately sealed in the standard version.

Vertical mounting positions for the IM V15 and IM V35 require circulating-oil 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'

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) should be a cup wheel type pulley. For mounting the belt 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.

Motors with built-on planetary gearbox

The 1PH motors can also be supplied with flange-mounted planetary gearboxes. The motor-gearbox unit is tested for correct functioning. The complete drive unit - that is, 1PH7 or 1PH4 motor with mounted ZF change-speed gearbox - can be ordered directly from Siemens:

On request


For further binding technical specifications and configuring aid (e.g. lubrication, temperature rise and typical applications), please refer to the latest catalog supplied by ZF (Zahnradfabrik Friedrichshafen). The permissible characteristics of the motor and gearbox are a governing factor in the design of the complete drive unit (motor and gearbox).With 1PH4168 or 1PH7167-2NB motors, for example, the rated torque must be reduced to 300  Nm (221 lbƒ-ft). With motors of SH132, please note that the maximum permissible speed of the 2K 250 gearbox for splash lubrication is 6300 rpm.
