Helical bevel gearboxes are a type of gearboxes consisting of at least two reduction stages, one stage being bevel gear wheels and the next being helical gear wheels. This type of gearboxes is characterized by very high efficiency reaching 97%. The main advantages of helical bevel gearboxes include high resistance to bending and their silent running. Depending on the gear ratio, we have two-, three- and four-stage gearboxes.

Motovario helical bevel gearboxes are marked with symbols: BA, B, CBA, IBA, CB, PB, IB.

The Motovario supplies helical bevel gear units in several versions:

  • flange-mounted gearbox for IEC or NEMA standard electric motors
  • flange-mounted gearbox for servomotors
  • gearbox with integrated motor
  • reducer with input shaft with keyway

The gearing range of Motovario helical gearboxes is in the range from I=7.62 to I= 442.76.

An important advantage of helical bevel gearboxes is also the possibility of output configuration:

  • hollow shaft with keyway groove (two diameters available)
  • solid shaft with keyway (single or double sided)
  • smooth hollow shaft with clamping ring
  • hollow shaft with multi-keyway
  • smooth hollow shaft with reduction bushings and clamping ring
  • foot, flange or reaction arm mountings
  • reverse motion’s blocking (optional)

ATEX-certified gearmotor versions are available for use in potentially explosive environments.
