| Speed Variations |
 |
| By feeding fixed speed to Variator, steeples speed variation can be obtained from |
| |
|
|
|
| |
| Torque Multiplier |
|
| When speed is reduced, Variators can replace Gear Boxes. |
|
| |
| Speed Multiplier |
|
| Up to 1.7 times input speed without necessity of speed increasing gear. |
|
| |
| High Output Torque - Over Load Capacity: |
| |
| Up to the standstill of an electric motor of the same power acting as a mechanical clutch. |
|
| |
| High Efficiency |
|
| Overall 85% throughout full speed range ideally used for constant power transmission applications in all types of Industries. |
|
| |
| Speed Holding |
|
| Quite stable with uniform load and within 0.25% with Max. Load. |
|
| |
| Reliability |
|
| Drive is highly reliable with long life as load is equally distributed on number of conical Rollers, which are hardened, and ground to close tolerance. |
|
| |
| Simple Design |
|
| Can be attended by skilled fitter as no electronic/electrical parts/circuits are involved. |
|
| |
| Compactness |
|
| High Power Transmission capacity with small dimensions. |
|
| |
| Speed Control |
|
| Quick and simple. By rotating control knob in running condition only. |
|
| |
| Free From Noise And Vibrations |
|
| No moving parts like Chins, Belts, etc. Drive is through rolling action of PRECISION ROLLERS, which are continuously lubricated. All components are well balanced. |
|
| |
| Bi-directional Rotation Of Output Shaft |
|
| Clockwise/Anti Clockwise depending upon Input shaft rotation, viz. Anti Clockwise/Clockwise respectively. |
|
| |
| Totally Enclosed Unit |
|
| Ideal for hazardous zones. |
|
| |
| Maintenance |
|
| Practically maintenance free. Only ensure proper lubrication. |
|
| |
| Collinear Input & Output Shaft |
|
| In-Line Input and Output Shafts. |

| |
| Before Selecting the Variator Consider Following: |
|
 |
Load Factors |
| » Uniform load: 1 |
| » Medium shock load: 1.5 |
| » Heavy shock load: 2 |
| |
|
|
Service factors |
| » 8 Hours running – 1 |
| » 16 Hours running – 1.25 |
| » 24 Hours running – 1.5 |
| |
|
|
