Precision ground gears are manufactured by using abrasive wheels to grind a gear blank to match the required gear design. These versatile gears are better suited to use with fine instrumentation and additional small-scale elements, and in high precision applications.
More accurate complete: Precision ground gears feature a more exact tooth Ground Helical Gear Racks complete than machined or cut gears, which provides better, smoother meshing of gear teeth for more managed operation.
More material options: While machining, stamping, and other manufacturing processes may limit materials options, nearly any steel or alloy could be made into a gear via grinding.
Higher loads & better performance: Due to how they’re manufactured, surface gears are generally able to handle higher loads and higher stresses than gears produced via other means. Surface gears are specially useful in applications that require huge amounts of torque.Thanks to these unique advantages, generally in most applications, precision ground gears may outperform gears manufactured through other means. Floor gears deliver smoother performance and greater longevity.
Bevel Equipment – Bevel gears, sometimes just called bevels, are cone shaped gears made to transmit motion between intersecting axes. They are usually mounted on shafts that are 90 degrees aside, but could be designed for nearly any angle. Another related term you might here is miter gear, which really is a type of bevel gear where the mating pairs have the same number of teeth.

Ground Gear – Floor gears are made by the manufacturing procedure for gear grinding, also known as gear tooth grinding. Equipment grinding produces high precision gearing, so surface gears can handle meeting higher quality requirements (AGMA, DIN, JIS or ISO) than cut gears. Gear grinding is particularly effective when gears distort during the heat treat procedure and tooth forms no longer satisfy drawing requirements. Both spur and helical gears can be produced using this method.

Helical Gear – While the teeth upon spur gears are cut directly and installed parallel to the axis of the gear, the teeth on helical gears are cut and ground on an angle to the face of the gear. This allows the teeth to engage (mesh) more gradually therefore they operate more smoothly and quietly than spur gears, and may usually carry a higher load. Helical gears are also called helix gears.
