PRODUCT PARAMETERS:

The manufacturing materials and heat treatment process of the gear have a great impact on the bearing capacity and dimensional weight of the gear. Before the 1950s, Jinhua automobile gear used carbon steel, used alloy steel in the 1960s, and used surface hardened steel in the 1970s. According to the hardness, Jinhua automotive gear tooth surface can be divided into soft tooth surface and hard tooth surface two.

Jinhua auto gear soft tooth surface gear carrying capacity is low, but the manufacturing is relatively easy, good running, Jinhua auto gear is used for transmission size and weight without strict restrictions, as well as small production of general machinery. Because the small wheel load is heavier in the matched gear, so in order to make the working life of the small gear roughly equal, the hardness of the small wheel tooth surface is generally higher than that of the large wheel.
