(1) double metal radial sliding bearing;
(2) double metal radial and thrust a whole sliding bearing;
(3) axial thrust bimetal sliding bearing copper;
(4) the bimetal sliding bearing of special shape;
(5) the double metal solid lubricating sliding bearing and so on five big classes.
1 existing sintering bimetal sliding bearing manufacturing technology, Jane, oil bearing interface
Steel - copper metal composite bearing material, shaft sleeve, bearing ring, the thrust collar manufacturing, at the time, in China, including foreign companies in China set up wholly owned companies and joint ventures, manufacturing is given priority to, these products are in powder sintering process using the bearing factory, choose powder sintering process using the first producing metal composite bearing material, a plate of strip and roll belt material, whether to choose the wood material, to make the bearing parts, all need to the metal composite bearing material according to the different bearing products, specialized all kinds of cutting processing to end such as bearings, bushings, thrust bearing, thrust collar, etc. The whole process of product manufacturing.The traditional materials processing method removed, not only the material utilization rate is low (40 ~ 65%), but also cost cutting processing equipment and tooling mould, human.Work, fees, equipment, it's clearly a traditional blank forming technology, the harm of bushing with today's material saving, energy saving, building economical society of metal policies need to be extremely compatible.
Less 2 independent intellectual property rights of free cutting steel, copper alloy sintered bimetal sliding bearing
In order to save precious copper resources, we since 1986, sintering trial - pendulum rolling process, to create the industry's first near net forming type metal composite bearing parts (bimetal thrust bearing plate, shaft sleeve to more than 98% of the copper alloy steel replaced the original parts), the technology in 1988 for "anti-friction bearing composite material yield process method", the author apply for the Chinese invention patent, is listed as the project 1991: national torch plan [1], Beijing the rigorous scientific and technological achievements to promote projects [2].
Again after more than 20 years of trying to choose sintering - pendulum rolling method, the end of the bimetal sliding bearing all the varieties of the manufacturing technology of the entire renovation, until 2012, all completed from the material to the bimetal sliding bearing no less cutting production.
Independent intellectual property rights has no less cutting sintering bimetal sliding bearing series products are:
(1) double metal radial sliding bearing;Jiashan bearing nearly t (overall bearing, shaft sleeve, the net shape parts)
(2) the bimetal thrust bearing;(thrust bearing plate, ring, near net shape parts)
(3) double metal radial and thrust a whole sliding bearing;(the whole circle flanging thrust collar near net shape parts)
(4) double metal special shape sliding bearing;(concave and convex V, semicircle concave spherical and irregular shape, standard large)
(5) the double metal solid lubricating sliding bearing (type oilless self-lubrication) such as the five varieties.
