Precision surface gears are manufactured by using abrasive wheels to grind a gear blank to match the desired gear style. These versatile gears are better suited to use with good instrumentation and other small-scale parts, and in high precision applications.
More accurate complete: Precision ground gears include a more precise tooth finish than machined or cut gears, which gives better, smoother meshing of gear teeth for more controlled operation.
More materials options: While machining, stamping, and other manufacturing processes may limit materials options, nearly any metal or alloy can be made into a gear via grinding.
Higher loads & better performance: Because of how they’re manufactured, surface gears are generally in a position to handle higher loads and higher stresses than gears produced via various other means. Floor gears are specially useful in applications that want large amounts of torque.Thanks to these unique advantages, in most applications, precision ground gears may outperform gears produced through other means. Surface gears deliver smoother overall performance and greater longevity.
Bevel Gear – Bevel gears, sometimes just called bevels, are cone shaped gears designed to transmit motion between intersecting axes. They are usually installed on shafts that are 90 degrees apart, but could be designed for almost any angle. Another related term you may here’s miter gear, which is a kind of bevel gear in which the mating pairs Ground Helical Gear Racks possess the same amount of teeth.

Ground Gear – Floor gears are produced by the manufacturing procedure for gear grinding, also referred to as gear tooth grinding. Gear grinding generates high precision gearing, so ground gears are capable of meeting higher quality requirements (AGMA, DIN, JIS or ISO) than cut gears. Gear grinding is especially effective when gears distort through the heat treat process and tooth forms no longer fulfill drawing requirements. Both spur and helical gears can be produced using this method.

Helical Gear – While the teeth on spur gears are cut directly and installed parallel to the axis of the apparatus, 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 so they operate more smoothly and quietly than spur gears, and can usually carry an increased load. Helical gears are also known as helix gears.
