• Examples of dynamic pumps include centrifugal pumps, axial flow pumps,...read more

There are several types of gears including spur, helical, bevel, worm, rack and pinion, and planetary gears.

• Spur gears have straight teeth and are the most common type of gear.

• Helical gears have angled teeth for smoother and quieter operation.

• Bevel gears have cone-shaped teeth and are used to change the direction of rotation.

• Worm gears have a screw-like appearance and are used for high torque applications.

• Rack and pini...read more
