PIV Mechanical Variable speed gear box ( D- DRIVE ) Power Rating - 0.37 Kw to 15 Kw

Adjustable Center Variable Speed Pulley Drives

D- Drive is a variable speed geared motor, robust step less unit suitable for various industrial applications.

The unit is designed to provide low output speed at corresponding high output torque. The drive unit is manufactured from standard components and comprises of AC squirrel cage motor, variable speed drive and gearbox with case hardened profile ground helical gears. It can be easily adapted to any machine design. The unit is very compact and save time and money because they are ready to fit drive modules. The interior part of this drive is the variable speed pulley enclosed in a housing and connected to the gearbox and motor. The speed variation can be achieved by means of a hand wheel. Average life to be expected is about 10 years before major maintenance. Belt life would depend on application and environment. General experience is about 3 to 4 years life.

Features :

  • Speed variation ratio 6:1
  • Speed adjustment while the machine is in operation.
  • Life time lubricated.
  • Foot and Flange mounting to suit any position.
  • Suitable for hazardous outdoor and dusty locations.
  • Choice of Flame proof / TEFC / Brake motors.
  • Optional remote control and speed indicator.
  • Can be coupled with clutch brake assembly.
  • Dual speed motor can be incorporated to achieve higher variation ratios
