Mechanical Variable Speed Drives [P.I.V]
Salient Features
Speed Variations: By feeding fixed speed to Variator, steeples speed variation can be obtained from.
Max. Speed = 1.7 x Input speed to
Min. Speed = 1/7 x input speed
Max.Speed - Min.Speed = 12: 1 to 3: 1 depending upon selection
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.
