Precision floor gears are manufactured by using abrasive wheels to grind a gear blank to match the desired gear style. These versatile gears are better suitable for use with great instrumentation and additional small-scale components, and in high precision applications.
More accurate finish: Precision ground gears feature a more specific tooth complete than machined or cut gears, which gives better, smoother meshing of gear teeth for more managed operation.
More materials options: While machining, stamping, and other manufacturing procedures may limit materials options, nearly any metallic 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 other means. Surface gears are especially useful in applications that want large amounts of torque.Because of these unique advantages, in most applications, precision floor gears may outperform gears produced through other means. Surface gears deliver smoother efficiency and greater longevity.
Bevel Gear – Bevel gears, sometimes simply known as bevels, are cone Ground Helical Gear Racks shaped gears designed to transmit motion between intersecting axes. They are often installed on shafts that are 90 degrees aside, but can be designed for nearly any position. Another related term you might here is miter gear, which is a kind of bevel gear where the mating pairs have the same quantity of teeth.
Ground Gear – Floor gears are produced by the manufacturing process of gear grinding, also called gear tooth grinding. Gear grinding produces high precision gearing, so ground 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 process and tooth forms no longer satisfy drawing requirements. Both spur and helical gears can be produced like this.
Helical Gear – 
As 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 upon 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 may usually carry a higher load. Helical gears are also known as helix gears.
