Shenyang Hanwei High Precision Hard Surface Gear For Sale

Hard surface gear

Gears generally include gear tooth, tooth space, end face, normal plane, addendum circle, root circle, base circle, reference circle. The gear surface bearing capacity is related to the hardness of the gear surface; the higher hardness, the higher bearing capacity. According to the gear surface hardness, the gear transmission is divided into two types, namely hard surface gear transmission( gear surface hardness above 350HBS) and soft surface gear transmission ( gear surface hardness less than 350HBS) .

The advantages:

The hardened surface gears make the machine weight lighted, machine minimized, quality performance improved, and speed upgraded. Adopting the hard surface gears transmission reduces the volume of the transmission device greatly and decreases the manufacturing cost.

The development direction of future gears are heavy load, high speed, high precision, high efficiency, etc and striving to be small size, light weight, long life, and reliable economy.

The choice of the material

It is commonly used quenched and tempered steel, quenched steel, carburized and quenched steel, nitrided steel to manufacture gears.

Large size gear usually use cast steel ( its strength is slightly lower than forged steel) .

Light carrying open gear drive can use gray cast steel ( poor mechanical property) .

Ductile Iron can be partially replaced by steel gear.

In order to increase the gear bending strength, we generally choose high quality alloy steel whose characteristics of mechanical property, harden ability, hardened layer micro- structure , hardness, carbon potential layer depth distribution are higher.
