Miniature bearing mechanical technology technical purpose in the future

Mechanical technology development is one of the goals of future real miniaturization of micro mechanical technology, it requires that the function of new, small side swing, dm ( High speed spindle of indicators, the product of the bearing pitch diameter and rotational speed) More than 2. 5 x10mm ・ r min of line speed, high temperature above 600 ℃ under the condition of lubrication, friction and volatility is very mild, used in the special environment, no dust, small rolling fatigue, lubricant long-acting, convenient perfect bearing. Structure, is to develop a super miniature bearing outside diameter less than 1 mm. Material, is to develop a new bearing materials such as ceramic, plastic material, can prolong life best surface conditioning, do not use the rare element of environmental bearing steel and raw material of decomposition lubricant, etc. According to the present situation of our country mechanical and electrical industry, the development trend of rolling bearing industry as follows: the change from the capacity dimensions to quality benefit type, mainly around the accuracy, performance, life and reliability of the product indicators, such as increasing technology innovation and step into the bearing technologies, especially focusing on the bearing life and reliability, enhance the level of product manufacturing technology at the same time, adjust the product structure, strengthen the bearing structure design and application technology research, expanding and high precision, high added value and special bearing capacity, and according to the demand of the host on the development of high speed, high precision, high reliability, long life, low friction, low vibration, low noise bearings and high technical content of the intelligent unitized bearings, bearings, functional parts bearings and the defense industry and special working conditions using special bearings. Such as car wheel bearing unit, taper roller bearing used in large truck, trailer units, automotive steering machine bearings, machine tool spindle bearing unit, computer hard disk drive bearing unit, etc.
