Bevel / Miter Gear Boxes

Bevel / Miter Gear Boxes

In Bevel Gear Screw Jacks the input shaft is perpendicular to the axis of actuator movement and the drive is transferred through a Bevel Gear Arrangement to the Lift Screw which can be either a Machined Screw or Ball Screw.

These jacks can be made only in rotating screw type. In such a jack arrangement the nut is attached to the moving part of the machine or arrangement.

The advantages of the Bevel Gear Screw Jacks are:

• High Speed : Such types of jacks can have higher lifting speeds than the worm gear screw jacks.
• Compact arrangement. : The box sizes are compact in comparison to the Worm Gear Screw
  Jacks.

The limitations of the Bevel Gear Screw Jacks are:

• Low irreversibility: Mean the load may automatically start to move down when the motor is
  switched off. In such a scenario one must use a brake motor in place of a regular motor.
• Fixed mounting: Mounting arrangement is mostly fixed type.
• Design Arrangement : These are only available in rotating screw type.
