The external Helical gear drive called gear train and gearbox are mechanisms consisting of an assembly of gears, shafts, and other machine elements for mounting the rotating parts. Gear drives can alter the transmitted power by using different configurations of gears. A common use of gear drives is for reducing the speeds of motors and engines that typically run at thousands of revolutions per minute (rpm). This type of gear has a cylindrical form similar to spur gears. The difference is their teeth which are cut in a spiral wrapping around the cylinder. The helical gears drive is used because of their smooth and quieter operation.

Attributes:
• Thrust loads and increased sliding friction between teeth, helical gears operate at lower efficiencies than spur gears.
• Crankshaft gears are to give a smoother drive to the vast motors with multi-cylinders.
• Provides smooth running of an engine
• Other components of gear drives are the shafts, keys, couplings, bearings, housing, and flanges.

Applications:
An external helical gear drive is used in all engines.

• Material: Low Alloy Steel
