In determining the transmission shaft lifting glue not bad circumstances, is the drive shaft deformation, only the replacement. In the process of replacement is best choice for medium carbon steel, the specific reasons below:

Low carbon steel is good, but the strength of the relatively low hardness, weldability and cold stamping process is very good, can be used to produce all kinds of standard parts, shaft sleeve, containers etc.;

High carbon steel is poor, high hardness, fatigue strength difference, machinability is worse, do not enough toughness of shaft parts, easily broken. This kind of steel is suitable for making the static pressure bearing type, the wear resistance of the parts, such as heavy rail, roll. Proper heat treatment can also be part of making spring, wire rope and so on to high hardness, high wear resistance;

The main function of automobile transmission shaft is to support the rotating body, power transmission. General working conditions will bear alternating torque and tension and compression load, the shaft neck and the key parts to withstand greater friction and wear. Failure is the main form of fracture and local excessive wear, fatigue and overload fracture include fracture. The material should have enough material, the strength, stiffness and certain toughness, good abrasion resistance, high fatigue strength and machinability is good. Requested that the spindle has better comprehensive mechanical properties. The medium carbon steel after proper heat tre. The medium carbon steel after proper heat treatment (quenching and tempering, surface hardening, carburizing etc.) can obtain good comprehensive mechanical properties, to heart of toughness, surface wear-resistant parts.

Xingtai YUANTUO Weiye Industry & Trade Co., Ltd. (former Nangong City Tongda Auto Parts Factory) transmission shaft lifting glue suggest you the best selection of alloy quenched and tempered steel (is medium carbon steel category), general quenched and tempered steel hardenability is poor, low mechanical properties and is suitable only for smaller size and lighter load parts. Alloying element in steel can improve the modulation of hardenability, significantly enhance the effect of quenching surface hardening heat treatment without reducing the core toughness. Alloy steel with heat treatment (quenching and tempering) has the advantages of high strength, high wear resistance and good plasticity and toughness match, which has good comprehensive mechanical properties.
