VH+ worm gearbox

  • VH+ worm gearbox with hollow shaft, keywayed.

  • VH+ worm gearbox with shrink disc

  • VH+ worm gearbox with integrated planetary input stage for higher ratios

Powerful torque but quiet running

The VH+ worm gearbox with a backlash ≤ 2 arcmin is characterised by a perfectly dimensioned output bearing for absorbing high axial and radial forces.The gearbox is therefore well suited for high input speeds..

Product highlights

Strong performance

The VH+ worm gearbox convinces with a strong performance in economical standard applications in cyclic and continuous operation.

No stick-slip-effect

The stick-slip effect is not an issue in applications with the VH+ thanks to the perfected hollow-flank toothing.

High flexibility

In addition to the hollow shaft, the worm gearboxes are also available in a corrosion-resistant design.

Constant low backlash

Constant low backlash over the entire service life affords consistent high quality with high positioning accuracy.

Radial shaft seal

  • Very long service life
  • Optimized for continous operation

Hollow-flank toothing

  • High accuracy of torsional backlash throughout the entire service life
  • High efficiency and extremely high power density

Input bearing

  • Bearing package for absorbing axial and radial forces
  • very well suited for high input speeds

Metal bellows coupling

  • Completely backlash-free
  • Fatigue endurable and maintenance-free
  • Easy to mount
  • Integrated length compensation feature protects the motor

Output bearing

High overload capacity for absorbing axial and radial forces
