Double Helical Gearing •Good Load Carrying capability •Parallel offset shafts. •Sometimes fabricated gear •Usually from Heat Treatable Material •Minimizes axial thrust •Difficult to accurately produce. •Efficiency up to 99% per stage. •Max Ratio 5 : 1 per stage

Bevel Gearing •Good Load Carrying capability •Turns the motion thru 90 deg. •Low Noise •Usually Enclosed gears •Usually from Heat Treatable Material •Good wear resistance. •Efficiency up to 98% per stage. •Max. Ratio 5 : 1

Bevel Helical Gearing •Good Load Carrying capability •Turns the motion thru 90 deg. •Low Noise •Usually Enclosed gears •Usually from Heat Treatable Material •Good wear resistance. •Efficiency up to 98% for the bevel and 99% per stage for the helical gears.

Bevel Helical Gearing - Applications

Planetary Gearing •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 pinions. •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 • Compact Drive - particularly for high ratios •Ratios up to 87:1 in 1 stage •Not available for high powers •Not available in right-angle design •Requires special excentric bearing •Efficiency up to 92% per stage

TORQUE TORQUE is the most important factor in Mechanical Power Transmission TORQUE has relationship between input POWER,input SPEED,RATIO M2=9550*P1*i/n1 M2=torque(N.m) P1=input power(kw) n1=input speed(rpm) i=gearbox ratio

Absorbed Power vs Rated Power  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.
