Arts: What are the properties of lead-based babbitt alloys

In industrial production, babbitt alloy is usually used, and the alloy is mainly invented by American inventor Babbitt. Since its invention, it occupies a certain advantage in the field of industrial production, and its use has become more and more extensive. However, with the improvement of industrial production technology, there are more and more types of babbitt alloys. Different industries have completely different effects when using babbitt alloys. Arts said that for some companies that have relatively high requirements for bearing capacity, lead-based babbitt alloys need to be used when processing and manufacturing, but when using this alloy, it is necessary to check the main performance Understand.

Arts said that babbitt alloys are mainly used in the bushes, bearings, bushings, and sleeves of large mechanical spindles. Such as: cement machinery, steel machinery, chemical machinery, papermaking machinery, petroleum machinery, ship machinery, compression machinery, coal mining machinery, mineral processing equipment, etc., can also be used on large machine tools to replace brass, and the effect is also very good.

Lead-based Babbitt alloy has high compressive strength (Guide: What factors affect the high-speed cutting of vertical machining centers?)

When using lead-based babbitt alloy, it can bear greater pressure, and its use will be relatively wide. At the same time, through the use of lead-based babbitt alloy, production safety can be ensured and construction personnel can be better protected Personal safety. Arts said that in addition to the manufacture of sliding bearings, babbitt alloys are often used as bearings by spraying their wire or powder on steel and other substrates because of their soft texture and low strength. In order to prevent component segregation and refine grains, a small amount of arsenic is often added.

Arts said that the fatigue resistance of lead-based babbitt alloy is great

There are two types of lead-based alloys. The latter contains 10%-20% antimony and 5%-15% tin. In order to prevent segregation of components and refine grains, a small amount of arsenic is often added. The strength and hardness of lead-based alloys are lower than that of tin-based alloys, and the corrosion resistance is also poor. For the workers in the industrial production industry, they all know that the alloy has the largest bearing capacity when in use, and it also has a certain degree of fatigue. Arts said that, in fact, the fatigue resistance of the alloy mainly refers to the use time of the alloy. The fatigue resistance of lead-based babbitt alloy is relatively high, so the use of the alloy is more extensive.

Arts said that the anti-friction performance of lead-based babbitt alloy is good

In addition to making sliding bearings, Babbitt alloys are often used as bearing bushes by spraying their wire or powder on steel and other substrates because of their soft texture and low strength. In order to prevent component segregation and refine grains, a small amount of arsenic is often added. The friction coefficient of lead-based babbitt alloy is relatively small, so when it is used, the friction force generated between it and other parts will be small, so that the parts can be better protected, and the service time of the parts can be prolonged and reduced. The corresponding production cost.

Arts said of course that lead-based babbitt alloy has a very important performance, which has good running-in and thermal conductivity, as well as good corrosion resistance.
