  • Study 29 Terms | Gears Flashcards | Quizlet

    Helical gears have their teeth inclined to the axis of the shafts in the form of a helix, hence the name helical gears. These gears are usually thought of as high speed gears. Helical gears can take higher loads than similarly sized spur gears. The motion of helical gears is smoother and quieter than the motion of spur gears.

  • What is Gear lapping and Gear Grinding Process

    A gear may be finished in several different ways, such as lapping or grinding. What is gear lapping? Gear lapping is the process of imparting a very fine finish and high degree of accuracy to gear teeth, by using a lapping tool and applying a fine-grained abrasive between a work material and a closely fitting surface, called a lapping plate.

  • Helical Gears - How Gears Work | HowStuffWorks

    The teeth on helical gears are cut at an angle to the face of the gear. When two teeth on a helical gear system engage, the contact starts at one end of the tooth and gradually spreads as the gears rotate, until the two teeth are in full engagement. This gradual engagement makes helical gears operate much more smoothly and quietly than spur gears.
