Other Gears
Crown Gear Factory
A crown gear (also known as a face gear or a contrate gear) is a gear that has teeth that project at right angles to the face of the wheel. In particular, the crown gear is a bevel gear where the pitch cone angle is 90 degrees. A pitch cone of any other angle is called a bevel gear. Crown gears typically mesh with other bevel gears or sometimes spur gears, a typical use being a crown gear and pinion system, which allows a rotary motion to be shifted 90 degrees.
Hypoid Gear
Hypoid gears are beveled gears similar to spiral ones, except they transmit motion between axes that do not intersect. The small gear shaft (hypoid pinion side) is offset from the giant gear shaft (hypoid gear side). Given the proper offset amount, the pinion shaft and large gear shaft can pass without interference, enabling the shafts to be supported securely on both ends.
Screw Gear crossed helical gears
Screw gears, also sometimes called crossed helical gears, are helical gears used in motion transmission between non-intersecting shafts. Screw gears can be used to transmit power between non-parallel shafts. This is because the helical teeth allow the gears to mesh even when the shafts are not aligned. Screw gears are also able to transmit high torques, which makes them ideal for applications such as hoists and winches. Screw gears can be made from a variety of materials, including steel, stainless steel, and plastic. The material used will depend on the application and the loads that the gear will be subjected to.
Herringbone Gears
A herringbone gear is a combination of double helical gears with two helices arranged on opposite sides of the hand. The teeth of the herringbone gears are arranged at an angle called the helix angle, with no gaps between the left and right helixes, appearing in the shape of the letter “V” These letters together form a pattern that resembles a fishbone structure. Since this structure has more than two teeth meshing with each other at the same time, the advantage is that the power transmission is smooth.
