Precision surface gears are manufactured through the use of abrasive wheels to grind a equipment blank to match the 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 specific tooth finish than machined or cut gears, which gives better, smoother meshing of gear teeth for more controlled operation.
More materials options: While machining, Ground Helical Gear Racks stamping, and other manufacturing procedures may limit material options, nearly any steel or alloy could be made into a gear via grinding.
Higher loads & better performance: Because of how they’re manufactured, surface gears are generally able to handle higher loads and higher stresses than gears produced via various other means. Floor gears are especially useful in applications that require large amounts of torque.Because of these unique advantages, generally in most applications, precision surface gears may outperform gears produced through other means. Ground gears deliver smoother functionality and greater longevity.
Bevel Equipment – Bevel gears, sometimes simply called bevels, are cone shaped gears designed to transmit movement between intersecting axes. They are usually mounted on shafts that are 90 degrees apart, but can be designed for almost any angle. 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 – Ground gears are produced by the manufacturing process of gear grinding, also referred to as gear tooth grinding. Equipment grinding generates high precision gearing, so floor gears can handle meeting higher quality requirements (AGMA, DIN, JIS or ISO) than cut gears. Gear grinding is especially effective when gears distort during the heat treat procedure and tooth forms no longer satisfy drawing requirements. Both spur and helical gears could be produced like this.
Helical Gear – As the teeth upon spur gears are cut straight and mounted parallel to the axis of the gear, the teeth upon 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 efficiently and quietly than spur gears, and will usually carry an increased load. Helical gears are also known as helix gears.
