Precision surface gears are manufactured by using abrasive tires to grind a gear blank to match the Ground Helical Gear Racks required gear style. These versatile gears are better suitable for use with great instrumentation and other small-scale parts, 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 equipment teeth for more managed operation.
More material options: While machining, stamping, and other manufacturing processes may limit materials options, nearly any steel or alloy can be made into a gear via grinding.
Higher loads & better performance: Due to how they’re manufactured, ground gears are generally able to handle higher loads and higher stresses than gears produced via various other means. Ground gears are specially useful in applications that require huge amounts of torque.Thanks to these unique advantages, generally in most applications, precision surface gears may outperform gears manufactured through other means. Surface gears deliver smoother overall performance and greater longevity.
Bevel Equipment – Bevel gears, sometimes just called bevels, are cone shaped gears designed to transmit motion 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 may here is miter gear, which really is a type of bevel gear in which the mating pairs possess the same quantity of teeth.
Ground Gear – Floor gears are made by the manufacturing procedure for gear grinding, also called gear tooth grinding. Gear grinding generates high precision gearing, so surface gears are capable of meeting higher quality requirements (AGMA, DIN, JIS or ISO) than cut gears. Gear grinding is particularly effective when gears distort through the heat treat process and tooth forms no more meet drawing requirements. Both spur and helical gears can be produced like this.
Helical Gear – While the teeth on spur gears are cut directly and mounted parallel to the axis of the gear, the teeth on helical gears are cut and ground upon an angle to the facial skin of the gear. This enables the teeth to engage (mesh) more gradually so they operate more easily and quietly than spur gears, and can usually carry an increased load. Helical gears are also known as helix gears.
