CNC Design introduces the Alpha Gearbox for Siemens synchronous and asynchronous servomotors. Flanged directly to the end drive of the motors, these units combine to form compact and coaxial drive units. Two versions are available:

1. Planetary Gearing SP Series for Siemens 1FT6 Servomotors

  • High efficiency > 94% two-stage, > 97% single-stage
  • Power transmission from the central sun gear via planetary gears
  • No shaft deflections occur in the planetary gear due to the symmetrical force distribution
  • Very low moment of inertia and hence short acceleration times of the motors
  • Output shaft bearings dimensioned for high cantilever and axial loads with preloaded tapered-roller bearings

2. Planetary Gearing LP Series for Siemens 1FK7 Servomotors

  • High degree of efficiency > 97% single stage
  • Torque play: Single-stage <=12 minutes of the arc
  • Power transmission from the central sun gear via planetary gears
  • No shaft deflections in the planetary gear set due to the symmetrical force distribution
  • Output shaft of gear unit exactly coaxial with the motor
  • Suitable for all mounting position
  • Low weight with degree of protection IP64

The following factors should be taken in to consideration when planning:

  • The permissible speed of the gear unit should not be exceeded by the maximum speed of the motor.
  • In the case of high operating frequencies, please make allowances for the jolt factor.
  • The frictional losses of the gear unit must always be taken into account in planning.
  • The gear units are only available in non-balanced design.
