3. bearing working life
Because material, processing, heat treatment and do not have surface treatment, common joint shaft bearing is not high working life, adds the restriction of maintaining and working condition, and its life-span is lower than more and should has the ability.
4. maintenance and repair cost
Because additional corresponding auxiliary facility, common joint shaft bearing need spend more cost of labor and carry out maintenance and repair, and this not only causes the waste of a large amount of manpower and materials, also can produce a very large impact the efficient of equipment own, even can cause unnecessary harm.
5. the saving of steel product cost
China is that steel use big country, is difficult to statistics because of product early failue causes damage, and for joint shaft bearing, if can significantly improve working life, will have an immense impact on to China's steel saving.
Follow the innovation of China's science and technology ability to improve, many new and high technologies progressively are applied to production field.The renewal of self lubricating material and the maturation of electroplating technology are for the development of self oiling bearing is established deep basis and brought far-reaching prospect.
(3) summary of the invention
The present invention has overcome above defective, and a kind of higher wear resistance that has is provided, and is dustproof, anticorrosion, and non-maintaining self-lubricating type plain radial bearing.
A kind of self-lubricating type maintenance-free spherical plain radial bearing comprises bearing outer ring and bearing inner race, it is characterized in that: described bearing outer ring and bearing inner race all adopt the vacuum outgas high-carbon-chromium bearing steel to make, and are attached with self lubricating material on the bearing outer ring.
The more excellent technological scheme of the present invention is: described bearing inner race surface is provided with the chromium layer.Described chromium layer is an electrodeposited coating.The two ends of bearing are provided with seal ring.
