    The advantage of High Precision Hard Surface Helical Gear

    As is known to all, Helical Gear strength design from considering the tooth surface pressure lubrication condition and dedendum intensity of two aspects.With the development of technology and the application of computer technology development, the transmission is adopted hard-toothed surface.
    According to statistics, because of the hard surface Helical Gear greatly promoted the machine adopts the weight, quality and improving the performance of miniaturization, make the machine working speed increase a level.Such as high-speed wire mill of rolling speed from past 30 to 90 under/s 120m - / s. Using hard-toothed surface Helical Gear transmission device that can greatly reduce the volume of, can reduce production cost.
    Nitride hard-toothed surface of hard-toothed surface, because nitriding depth is very shallow, unsuited to do lowe-speed heavy duty Helical Gear , and  Helical Gear nitride process itself is expensive, so rarely used.
    Surface hardening (such as high, medium or flame hardening) of hardening layer and the transition of hardening layer, hardness distribution interface tonsure too big, while hardening quality uneven, hardening, root surface crack crosses into the surface hardness, low Helical Gear HRC55 (left) so gradually reduce application.
    Layer carburizing quench grinding high-precision, hard surface Helical Gear, high precision, high surface hardness HRC58 (4), + tooth surface hardening layer uniform etc advantages, especially suitable for low speed and heavy Helical Gear. Its surface hardness, the contact strength than piece.modified Helical Gear, and bending strength piece.modified Helical Gear about increased by more than 50%. FALK, (LUS) so the rand corporation and Citroen, DuLang company - messiaen - all adopt deep carburizing quench - grinding Helical Gear-. High precision hard surface Helical Gear represents industrial, Marine Helical Gear transmission device development direction.
    Suzhou Asia Pacific Metal Co.,Ltd, start from the factory, because of its service properties determine its tracking world advanced technology, using alloy steel manufacturing carburizing quench - mill tooth - high-precision hard surface gears. The practical application of long-term abrasion proof, gear rolling bearing surface can be matched with no need to worry, tooth surfaces wear and corrosion, and the bending strength also have big room
