Product Description
Mechanical Variable Speed Drives
These are positive mechanical variable speed drives. With the input speed of 1800 rpm, the drive gives 0 - 400 rpm continuously variable.
Available in five sizes providing constant torque of 12 to 60 lb inch throughout the speed range.
The following are process control benefits that can be provided by an adjustable speed drive:
| Features | Benefits |
| Positive Drive | This is not a Friction Drive. No Slip between |
| Compact | Small size compared to torque and weight |
| Simple operation | Lever or screw control. |
| Constant Torque | Constant torque throughout the speed range |
| 4 : 1 speed reduction | Can be used without additional reducer in most cases. |
| Change speed anytime | Whether in running or static condition |
| Change speed continuously | Ideal for dancer application / constant speed changes |
| Zero Speed Output | Ideal for use as a clutch |
| Sealed housing | Use in most atmospheres – can be mounted in any |
| Versatile | Shaft / Control / Motor options |
| Infinitely adjustable | 0 – 400 RPM speed range with 1800 RPM input. |
| Speed Lock | Handle for speed change also works as a speed lock, |
| Unidirectional Output | Irrespective of the change in input |
| Jogging Operation | To & Fro movement on handle can provide jogging |
| Output shaft mechanically free from the input shaft | Output shaft can be freely rotated [even manually] |
