The external helical gear crankshaft is a cylindrical toothed gear with teeth parallel to the shaft and is used to transfer mechanical motion as well as control speed, power, and torque between shafts. A crankpin journal is a precision ground surface that provides a rotating pivot point to attach the connecting rod to the crankshaft gear. 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. Helical gears are used because of their smooth and quieter operation. The downside of using helical gears is the larger thrust load imposed on the supporting bearings.

Attributes:
• External helical gears are superior to spur gears in their load-carrying capacity and quietness and smoothness of operation
• Function of crankshafts gears are to give a smoother drive to the vast motors with multi-cylinders.
• Provides smooth running of an engine.

Applications:
An external helical crankshaft is used in all generators, bulldozers, engine motors, etc.

• Material: Low Alloy Steel
