Precision ground gears are manufactured through the use of abrasive tires to grind a equipment blank to match the desired gear style. These versatile gears are better suited to use with great instrumentation and other 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 provides better, smoother meshing of gear teeth for more controlled operation.
More materials options: While machining, stamping, and other manufacturing procedures may limit material options, nearly any metal or alloy could be made into a gear via grinding.
Higher loads & better performance: Because of how they’re manufactured, floor gears are generally able to handle higher loads and higher stresses than gears produced via Ground Helical Gear Racks various other means. Surface gears are specially useful in applications that want huge amounts of torque.Because of these unique advantages, generally in most applications, precision surface gears can outperform gears produced through other means. Surface gears deliver smoother performance and greater longevity.
Bevel Equipment – Bevel gears, sometimes simply known as bevels, are cone shaped gears designed to transmit movement between intersecting axes. They are usually mounted on shafts that are 90 degrees aside, but can be designed for nearly any position. Another related term you may here is miter gear, which really is a kind of bevel gear where the mating pairs possess the same number of teeth.
Ground Gear – Floor gears are produced by the manufacturing procedure for gear grinding, also known as gear tooth grinding. Gear grinding creates high precision gearing, so floor gears can handle meeting higher quality requirements (AGMA, DIN, JIS or ISO) than cut gears. Equipment grinding is particularly effective when gears distort during the heat treat procedure and tooth forms no longer meet up with drawing requirements. Both spur 
and helical gears could be produced using this method.
Helical Gear – While the teeth on spur gears are cut directly and mounted parallel to the axis of the apparatus, the teeth on helical gears are cut and ground upon an angle to the face of the gear. This allows the teeth to activate (mesh) more gradually therefore they operate more easily and quietly than spur gears, and can usually carry a higher load. Helical gears are also known as helix gears.
