HT250 Grey Cast Iron Timing Belt Pulley
About Synchronous wheel
Synchronous pulley drive is composed of a ring belt with equally spaced teeth on the inner circumference surface and a pulley with corresponding teeth, when running, the belt teeth mesh with the teeth groove of the pulley to transmit motion and power, it is a new belt drive that integrates the advantages of belt drive, chain drive and gear drive.
Overview
Material
Gray cast iron, consisting mainly of silicon, sulfur and carbon, is used not only in industrial manufacturing but also in stuffing boxes and towers. It is often used to make various parts because of its excellent wear resistance and heat resistance. In addition, it is also widely used in the construction field because of its good stability and low process requirements and costs.
Reasons for the Material
1. Good wear resistance and vibration elimination. Because graphite in cast iron is good for lubrication and oil storage, so the wear resistance is good. Similarly, due to the presence of graphite, gray cast iron has better vibration dissipation than steel. 2. good process performance. Because of the high carbon content of gray cast iron, close to the eutectic composition, so the melting point is relatively low, good mobility, small shrinkage, so suitable for casting complex structure or thin-walled castings. In addition, because graphite is easy to form chip breakage during cutting, so the machinability of gray cast iron is better than steel. 3. the relationship between hardness and tensile strength: between the hardness and tensile strength of gray cast iron, there is a certain correspondence. The empirical relationship is: a, when O ≥ 196N / m ㎡ HB = RH (fly 00 + 0.4380b) ...... (B1) b, when O ≥ 796N / m ㎡ HB = RH (44 + 0.7240b) ...... (B2) formula The relative hardness (RH) value is mainly determined by the original village material, melting process, treatment process and the cooling rate of the casting.
Surface Treatment
This timing belt pulley uses the blackening treatment to improve the rust-proof performance and extend the service life of metal products.
