Chain Wheel, Gear is a mechanical component that has gears on the rim that continuously mesh to transmit motion and power. The use of gears in transmissions has long appeared. At the end of the 19th century, the principle of the incision method and the special machine tools and tools that used this principle to cut the teeth appeared one after another. With the development of production, the stability of the gear operation was taken seriously.
Chain Wheel, Gear
Foring carbon steel, stainless steel
T teeth, high precision, even pitch of teeth, complicated angle
Used in automobile, agricultural machinery, engineering machinery, joint swivel parts with good heat treatment to improve hardness
Enhancing wear resistance and toughness
Chain Wheel, Gear is based on hardness, and the tooth surface can be divided into soft tooth surface and hard tooth surface.
The soft tooth surface has a low load carrying capacity, but it is easy to manufacture and has good running performance. It is often used in general machinery where the size and weight of the transmission are not strictly limited, and in small quantities. Because the paired gears have a heavier burden on the small wheels, the hardness of the small gear teeth is generally higher than that of the large wheels in order to make the working life of the large and small gears substantially equal.
The hard-toothed gear has high bearing capacity. After the gear is cut, it is quenched, surface hardened or carburized and quenched to improve the hardness. However, in the heat treatment, the gear is inevitably deformed, so it is necessary to grind, grind or finish after the heat treatment to eliminate the error caused by the deformation and improve the accuracy of the gear.
