SIMOGEAR Helical Bevel Gear Motors

helical bevel geared motors - cutaway

Helical bevel are angular geared motors where the gear unit output shaft is rotated 90° to the motor shaft. Units can either have a solid or a hollow shaft. Helical bevel geared motors represent the ideal solution for drive tasks where an angular geared motor with high power density is required with continuously high output torques

SIMOGEAR  helical bevel geared motors are available for the power range up to 20 HP (15 kW) and rated gear unit torques up to 5,900 ft-lb (8,000 Nm).

Helical Bevel Gear Motors 2 percent advantage

The Power of Two Percent

SIMOGEAR 2-stage helical bevel unit yield higher ratios in the first gear stage than traditional designs. All told, the unit averages 2% higher efficiency than 3-stage units. For any continuous duty application, that translates to substantial energy savings over the long term.
