Precision ground gears are manufactured by using abrasive wheels to grind a equipment blank to match the Ground Helical Gear Racks required gear style. These versatile gears are better suited to use with good instrumentation and additional small-scale elements, and in high precision applications.
More accurate complete: Precision ground gears feature a more exact tooth finish than machined or cut gears, which provides better, smoother meshing of equipment teeth for more managed operation.
More materials options: While machining, stamping, and other manufacturing processes may limit material options, nearly any metal 
or alloy can be made into a gear via grinding.
Higher loads & better performance: Due to how they’re manufactured, surface gears are generally in a position to handle higher loads and higher stresses than gears produced via additional means. Surface gears are specially useful in applications that require large amounts of torque.Thanks to these unique advantages, generally in most applications, precision floor gears can outperform gears produced through other means. Ground gears deliver smoother performance and greater longevity.
Bevel Equipment – Bevel gears, sometimes just called bevels, are cone shaped gears designed to transmit motion between intersecting axes. They are usually mounted on shafts that are 90 degrees aside, but could be designed for nearly any position. Another related term you might here is miter gear, which really is a type of bevel gear where the mating pairs possess the same quantity of teeth.
Ground Gear – Floor gears are made by the manufacturing procedure for gear grinding, also known as gear tooth grinding. Equipment grinding creates high precision gearing, so ground gears are capable of meeting higher quality requirements (AGMA, DIN, JIS or ISO) than cut gears. Equipment grinding is particularly effective when gears distort during the heat treat process and tooth forms no longer satisfy drawing requirements. Both spur and helical gears could be produced using this method.
Helical Gear – As 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 so they operate more smoothly and quietly than spur gears, and will usually carry a higher load. Helical gears are also known as helix gears.
