All About Bevel Gears - What They Are and How They Work

WebThe left pair of gears makes external contact, and the right pair of gears makes internal contact Parallel helical gears Herringbone gears (or double-helical gears) Rack and pinion … Bevel gears are gears where the axes of the two shafts intersect and the tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well. The pitch surface of bevel gears is a cone, … See more Two important concepts in gearing are pitch surface and pitch angle. The pitch surface of a gear is the imaginary toothless surface that you would have by averaging out the peaks and valleys of the individual teeth. The … See more There are two issues regarding tooth shape. One is the cross-sectional profile of the individual tooth. The other is the line or curve on which the tooth is set on the face of the gear: in other words the line or curve along which the cross-sectional profile is projected to form … See more The bevel gear has many diverse applications such as locomotives, marine applications, automobiles, printing presses, cooling towers, power plants, steel plants, railway … See more Mitre gears are a special case of bevel gears that have equal numbers of teeth. The shafts are positioned at right angles from each other, and … See more The cylindrical gear tooth profile corresponds to an involute (i.e. a triangle wave projected on the circumference of a circle), whereas the bevel gear tooth profile is an octoid (i.e. a triangle wave projected on the normal path of a circle of a sphere). All … See more The teeth on bevel gears can be straight, spiral or "zerol". Straight tooth lines In straight bevel gears, the teeth are straight and parallel to the generators of the cone. This is the simplest form of bevel gear. It … See more • This gear makes it possible to change the operating angle. • Differing of the number of teeth (effectively diameter) on each wheel allows mechanical advantage to be changed.
