Bevel gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well. [1] The pitch surface of bevel gears is a cone, known as a pitch cone. Bevel gears change the axis of rotation of rotational power delivery and are widely used in mechanical settings. Bevel gear on roller shutter door.
A cycloidal gear is a toothed gear with a cycloidal profile. Such gears are used in mechanical clocks and watches , rather than the involute gear form used for most other gears. Cycloidal gears have advantages over involute gears in such applications in being able to be produced flat (making them easier to polish, and thereby reduce friction ...
Spiral bevel gear. A spiral bevel gear is a bevel gear with helical teeth. The main application of this is in a vehicle differential, where the direction of drive from the drive shaft must be turned 90 degrees to drive the wheels. The helical design produces less vibration and noise than conventional straight-cut or spur-cut gear with straight ...
Outer cone distance in bevel gears is the distance from the apex of the pitch cone to the outer ends of the teeth. When not otherwise specified, the short term cone distance is understood to be outer cone distance. Mean cone distance in bevel gears is the distance from the apex of the pitch cone to the middle of the face width.

Model KH and KHK 1954–1956: 888 cc side-valve engines, using the 45 model bore, but with the stroke increased to 4.5625" (115.89 mm). This was the only small twin with a stroke longer than 3.8125". The shorter stroke was otherwise universal to the entire 45/K/Sportster line from 1929 to the present (exception: XR750, XB9 Buell).
Bevel gear operating a lock gate. In a crossed arrangement, the axes of rotation of the two gears are not parallel but cross at an arbitrary angle except zero or 180 degrees. For best operation, each wheel then must be a bevel gear, whose overall shape is like a slice of a cone whose apex is the meeting point of the two axes.
Crown gear. A crown gear (also known as a face gear or a contrate gear) is a gear which has teeth that project at right angles to the face of the wheel. In particular, a crown gear is a type of bevel gear where the pitch cone angle is 90 degrees. [1] [2] A pitch cone of any other angle is simply called a bevel gear. [3]
