Introduction of Drive Wheels in Rail Electric Flat Cars
Drive Wheels in Rail Electric Flat Cars, power transmission of construction machinery excavator and bulldozer, on the excavator, because the whole is casting processing, so called "drive wheel", bulldozer because it is separated from a few pieces of casting or forging,It is called "drive gear block". The drive wheel is usually directly connected to the drive motor and directly transmits power to the track.This will drive the entire chassis forward.The material of the drive wheels in rail electric flat cars is mainly based on casting, but the driving tooth block of the high-power bulldozer is forged.Such products will withstand greater driving forces and thus ensure the quality of the product. No matter what kind of material,The product must be passed through rough casting (forging), machining, tooth quenching and other processes, and ultimately passed to customers.
Excavator drive wheels in rail electric flat cars are mainly cast products, the material is generally ZG40Mn, quench hardness and push of the tooth.Similar to the earth machine, HCR46-56, because the wheel is the overall processing, so the process is relatively simple, guarantee processing precision.Degree and dimensional accuracy can be.The teeth of rotary drilling rigs and bulldozers are mainly made of forgings because they are three-toothed or two-toothed.
Sculpted into a wheel, so the process is more strict with the technical requirements. Bulldozer tooth block requirements:The steel for the toothed block shall comply with the 40MnB or 35MnB alloy steel material specified in GB/T 3077, also permitting the use of force.The material of drive wheels in rail electric flat cars with not less than the above-mentioned grades shall be studied; the carbon content of the toothed block steel shall comply with the .regulations in GB/T 3077Determined; its sulfur, phosphorus content should be less than 0.035%. Steel non-metallic inclusions, brittle inclusions, plastic inclusions the content of the material shall meet the requirements of Class 2.5 in GB/T 10561-1989; the heat treatment hardness of the tooth block HCR46-56; forging ratio of tooth block should be greater than or equal to.
