•Good Load Carrying capability •Input/output shafts in line. •Ratios of up to 6 : 1 in each stage •Compact size for high torques. •Enclosed gears •Good wear resistance. •Efficiency up to 97% per stage. •Used in combination with other types of gearing particularly for final stage. Planetary Gearing - Applications Worm Gearing

•Good Load Carrying capability •Input/output shafts at right angles. •Ratios of up to 60 : 1 in each stage •Compact size for high ratios. •Un economic for high torques. •Low Noise. •Efficiency up to 90% per stage. •Used in combination with other types of gearing. Worm Gearing - Applications Power Split Gearing

•Good Load Carrying capability •Compact size for high torques, since the expensive final gear is driven by 2 or more . •Enclosed gears •Good wear resistance. •Efficiency up to 97% per stage. •Competitive Pricing Power Split Gearing - Applications

Cement Factory – Kiln Drive Sugar Mill – Final Drive Hydraulic Drives

•Variable speed capabilities •Power pack can be located away from the drive. •Suitable for a large variation of torques •Compact size. •Relies on quality of oil. •Lends itself to computer control. •Poor efficiency. Approx.70 to 80%. •Ease of mounting Hydraulic Drives - Applications

Sugar Mill – Pressure Feeder Drives Sugar Mill – Main Drive Cycloidal Drive

 You can put any size of motor on a drive BUT it will only produce the power required by a machine.

 With a S1 motor – it is designed to produce TWICE the RATED POWER when it starts and can maintain that POWER for a period of 2 minutes.

 Our Gear units also have this additional safety - Already built in

 Motors are also designed to cope with SHOCK LOADS – up to 5 times in any one hour period.

 Our Gear units also have this additional safety - Already built in TORK Mechanical Drives in the Sugar Industry TORQUE REQUIRED/ABSORBED BY MILL

 Power required by mill for 4000 TCD with 13.5% Fiber Content = 365.20 kW

 Mill Speed required to mill 4000 TCD = 4 rpm

Motor speed 991 rpm(Nominal) = 6 pole

 Torque (Nm) = Power (kW) x 9550 / n (rpm)

 Torque Nm = 365.20 x 9550 / 4 = 871.915 Nm SERVICE FACTOR (Sf)

Therefore the SERVICE FACTOR 2 = 871.915 x 2 = 1.743.830 Nm Therefore the SERVICE FACTOR 1,7 = 871.915 x 1,7 = 1.482.255 Nm (based on AGMA standard) TORK Mechanical Drives in the Sugar Industry

Additional Assurance

TORK have additional Taper Roller Bearings to take the THRUST LOADS from the tail bar.

 Larger output shaft diameters mean larger bearings.

Input and Output bearings are protected from abrasion by bagase dust by the use of grease filled labyrinth seals.

One of the competitors housing is fabricated steel – flexible and less shock/vibration absorbsion than a casting from GG 25. TORK Mechanical Drives in the Sugar Industry Thrust Bearings and Solid Square Output Shaft (Safety & Protected) Testing and Warranty
