1.Sintered iron – base bearing with wide surface and large dosage. It competes successfully with cast Babbitt alloy, bronze and 2.sintered bronze due to its rich 3.raw materials, which can be improved by adding and gold elements and additives to reduce friction. Compared with ordinary bronze, the sintered iron base bearing material of Welfine Technology has good wear resistance and high load capacity.
The high performance sintered copper-iron base bearing is made of copper-iron alloy as the main material by powder sintering technology. In order to improve its 4.self-lubrication performance, solid lubricant based on graphite is evenly dispersed within the material structure, and the 5. oil content is treated to obtain almost the same static friction and dynamic friction coefficient. These solid lubricants will be released to the bearing surface in time when friction occurs, forming a solid transfer film with low shear strength to achieve the purpose of self-lubrication. Welfine technology has successfully developed this new high performance sintered copper iron bearing with high load.
Oil bearing is used in many kinds of 1.mechanical equipment, such as motor industry, steam and friction industry, household appliance industry, digital products, office equipment, electric tools, textile machinery, packaging machinery and other kinds of machinery and equipment.
Generally speaking, 2.powder metallurgy oil bearing is made of raw material, pressed, sintered, reshaped and immersed in oil. Most of the machines nowadays are highly 3.automated in powder metallurgy. The daily output is relatively large, most products can be formed at a time, so the larger the batches, the better the production. Now, if we use fewer 4.oil bearing moulds, we may make hundreds of thousands of them. But the cost of mold is relatively high, so it will not be done if there is a lot of volume, and the time to change the mold is also long.
Generally speaking, powder metallurgy oil bearing can be formed at one time, basically without cutting. Cost is lighter than machine processing, material waste is less, and price is cheaper. It is also consistent with the national policy of promoting energy conservation. Therefore, it is considered to be a technology that will not outdated.
The base of powder metallurgy bearing oil bearing has been filled with lubricating oil in the vacuum immersion method, and the lubricating oil will exudate to the running surface because of the temperature rise and pump suction in operation, so it can be used in the situation of not adding the lubricating oil.
