Brass Spur Gear

Brass Spur Gear

In the eastern zhou dynasty, more than 2,400 years ago, brass spur gear has already been made by casting in China.In Shanxi Province map of houma zhou jin cast copper site was found pottery mould set of gear, there are different specifications of the 4 sets of gear with a hole, around eight teeth, this is one of the earliest known to gear casting.The early gears were mostly used for stopping, according to experts, and the ancients stopped and prevented the movement of the machinery, such as the windlass, to keep it from moving.

Heat treatment

Low carbon steel gears can be used to strengthen the surface of the teeth after carburizing and quenching.Carbon steel gears can be treated for nitrification and quenching, or hardening by using medium - high frequency heating surfaces (depending on the material and modulus).The surface strength and wear resistance of low carbon steel carburizing and quenching were significantly improved, and the core remained a high impact resistance.The carburizing and quenching layer is the thin martensite tissue, and the core of the core is the equilibrium tissue of ferrite and pearlite type.The outer layer of nitrification treatment of medium carbon steel should be composed of a small number of compounds and the permeable layer of the diffusion layer, which is the tempering sorobody tissue (or a small amount of free ferritic body).
