Precision floor gears are manufactured by using abrasive tires to grind a equipment blank to match the required gear style. These versatile gears are better suitable for use with fine instrumentation and various other small-scale elements, and in high precision applications.
More accurate complete: Precision ground gears feature a more precise tooth complete than machined or cut gears, which provides better, smoother meshing of gear teeth for more controlled operation.
More material options: While machining, stamping, and other manufacturing processes may limit materials Ground Helical Gear Racks options, nearly any metal or alloy could 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 additional means. Floor gears are especially useful in applications that require huge amounts of torque.Because of these unique advantages, in most applications, precision ground gears can outperform gears manufactured through other means. Ground gears deliver smoother overall performance and greater longevity.
Bevel Equipment – Bevel gears, sometimes simply called bevels, are cone shaped gears made to transmit movement among intersecting axes. They are usually mounted on shafts that are 90 degrees apart, but can be designed for almost any position. Another related term you might here is 
miter gear, which is a type of bevel gear where the mating pairs have the same number of teeth.
Ground Gear – Surface gears are made by the manufacturing process of gear grinding, also known as gear tooth grinding. Equipment grinding produces high precision gearing, so floor gears can handle meeting higher quality requirements (AGMA, DIN, JIS or ISO) than cut gears. Equipment grinding is especially effective when gears distort during the heat treat procedure and tooth forms no more satisfy drawing requirements. Both spur and helical gears could be produced like this.
Helical Gear – While the teeth upon 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 facial skin of the gear. This enables the teeth to activate (mesh) more gradually so they operate more smoothly and quietly than spur gears, and will usually carry an increased load. Helical gears are also known as helix gears.
