Drive shafts are mainly used to connect the universal joints of various mechanisms. Due to different mechanical equipment, the functions of various drive shafts are slightly different. For example, on the forklift, the drive shaft is used to transmit the power between the transmission and the transaxle. For forklifts below 3t, due to the short longitudinal dimension of the drive train, rigid joints are generally used, that is, a rigid whole from the engine to the drive axle, and a gear coupling is used in the middle of the rigid whole. For forklift trucks of 5t or more, due to the long longitudinal dimension of the transmission system, universal joints are generally adopted, so that the power is transmitted to the drive axle of the forklift through the drive shaft.
The heat treatment of the coupling is an operation technique in which the metal or alloy is subjected to an organic combination of heating, heat preservation and cooling in a solid state, and the metal or alloy is modified to obtain the desired function. The heat treatment of the drive shafts is a modern machine. In the industrial and metallurgical industries, there is no shortage of products to improve product quality and extend the service life of machine parts.
The heat treatment of the drive shafts is divided into preparation heat treatment and final heat treatment. In modern industrial production, the heat treatment of the drive shafts has become an extremely important technical specification. This is due to the excellent mechanical properties of steel and certain alloys - high hardness, strength, elasticity and wear resistance. The treatment is obtained by heat treatment in addition to the desired chemical composition during smelting.www.morayshaft.com
