Zinc alloy bearing - The new bearing alloy is an alloy composed of zinc as a base and other elements. Commonly added alloying elements are aluminum, copper, magnesium, cadmium, lead, titanium and so on. Zinc-based alloy has low melting point, good fluidity, easy fusion welding, brazing and plastic processing, corrosion resistance in the atmosphere, and easy recovery and remelting of disability materials; But the creep strength is low and the size change is easy to occur due to natural aging. Prepared by melting, die casting or pressure processing. According to the manufacturing process can be divided into cast zinc base alloy and deformed zinc base alloy.

Features of zinc alloy bearing:

1. The strength, hardness and allowable pressure are comparable to that of aluminum bronze, widely exceeding tin, lead, etc., and the allowable speed is similar. It can fully meet the use conditions of independent anti-friction and wear-resistant parts such as bearing shell.

2. Strong affinity for lubricating oil, better self-lubrication, coupled with its metallurgical characteristics (low melting point, not easy to metallurgical combination with steel shaft), so the use of strong anti-adhesion, anti-friction wear characteristics more prominent.

3. Low coefficient of friction, low wear, and therefore longer service life. Under the same use conditions, it is generally more than 1 times that of copper tile, thus reducing the procurement cost of accessories.

4. High thermal conductivity (ZZnAl27Cu2Mg λ=125; ZCuAl10Fe3λ =59), the heat dissipation is fast, the grinding surface temperature rise is slow and low, and the pairing friction has a better protection effect.

5. Low material density (ZZnAl27Cu2Mg ρ=5g/cm3), light product weight (the same model, the same specification weight 1/3), installation, maintenance is easier and more convenient.

6. With high damping characteristics, vibration and noise reduction.

The use of zinc alloy bearings

1. Auto parts: Auto parts are one of the main application areas of zinc alloy bearings, such as engine, transmission, direction machine and other parts need to use zinc alloy bearings to ensure the normal operation and safety of the car.

2. Electrical equipment: In all kinds of motors, zinc alloy bearings play a very important role. In addition, various electrical equipment in the chain, gear, support and other parts also need to use a lot of zinc alloy bearings.

3. Agricultural machinery: zinc alloy bearings are also widely used in agricultural machinery, such as rice transplanter, harvester, etc. The operation of these machines depends on stable load and reduce friction to ensure their normal work.

4. Construction machinery: construction machinery needs to withstand heavy loads and harsh environments, so it is necessary to choose high-performance zinc alloy bearings such as wear resistance, corrosion resistance and high temperature resistance. For example, excavators, bulldozers and other construction machinery need to use high-performance zinc alloy bearings.
