Zinc alloy bearings, a new type of bearing alloy
An alloy composed of zinc as the base and other elements added. Commonly added alloying elements include aluminum, copper, magnesium, cadmium, lead, titanium, etc. Zinc based alloys have a low melting point, good fluidity, are easy to melt and weld, undergo brazing and plastic processing, and are resistant to corrosion in the atmosphere. Residual waste is easy to recover and remelt; But the creep strength is low, and it is prone to size changes caused by natural aging. Preparation by melting method, die-casting or pressure processing into materials. According to manufacturing processes, it can be divided into cast zinc based alloys and deformed zinc based alloys.
Compared to Babbitt alloy
In addition to having significant cost-effectiveness advantages, it also has higher toughness, lower weight, and a wider range of applications.
Compared to bronze
1. The strength, hardness, and allowable pressure are comparable to aluminum bronze, widely exceeding tin, lead, etc., and the allowable speed is similar. It can fully meet the usage conditions of independent anti friction and wear-resistant parts such as bearings.
2. It has a strong affinity for lubricating oil and better self-lubricating properties. In addition, its metallurgical properties (low melting point, less likely to metallurgical bond with steel shafts) make it more resistant to adhesion and more prominent in reducing friction and wear during use.
3. Low friction coefficient, low wear, and therefore longer service life. Under the same usage conditions, it is generally more than twice the size of copper tiles, thereby reducing the procurement cost of accessories.
4. High thermal conductivity (ZnAl27Cu2Mg λ=25; ZCuAl0Fe3 λ=59), fast heat dissipation, slow and low surface temperature rise, providing better protection against paired friction.
5. The material density is low (ZnAl27Cu2Mg ρ=5g/cm3), and the product quality is light (light/3 of the same model and specification), making installation and maintenance easier and more convenient.
6. It has high damping characteristics and is resistant to vibration and noise.
