Bearings , are anti-friction devices, each having different anti-friction characteristics. By far the largest number of bearings are oil-lubricated. The oil film can be maintained through pumping by a pressurization system (pump). Or it can be maintained by a squeezing or wedging of lubricant ...
APPLICATION OF DIFFERENT TECHNICAL PLASTICS IN MECHANICAL ENGINEERING -- SLIDING BEARINGS.In recent decades the manufacturing of sliding surfaces made of technical plastics was developed rapidly. These new materials fulfill the economical and technical requirements of customers such as: lack of lubricant, ...
Different possibilities are explored to increase the feasibility of base isolation for such type of buildings. Strategies proposed in this study are ⅰ) increasing superstructure stiffness, ⅱ) increasing superstructure damping and ⅲ) increasing flexibility of isolation system. It is observed that the ...
and the life, wear and noise of grease bearings caused by aging of grease also need to be fully studied. Moreover, according to different uses, it is necessary to select special designed bearings for precision, NTN bearing clearance, cage structure, grease and so on. However, there ...

Contact Pressure in Wood Bushings of Sleeve Bearings However, wood as a material significantly complicates the calculation of sleeve-bearing pressure and limits their field of application in machines and mechanisms. One of the main problems is the need to take into account many parameters ... SI...
Numerical simulation results show that the effectiveness of the proposed approach under different scenarios and the performances comparison of different approaches are also performed. 展开 关键词: bearings-only track initiation data association clustering ...
The research on these materials continues to fulfill the new ideas of developing any field making the ceramics applications even more. Talking about structural applications, it mostly involves the use of monolithic ceramics. Some examples of structural applications of ceramic materials are bearings, ...
It should be noted that when the selected sampling points are small, the differential accuracy of the constructed differentiator filter will be reduced. The standard deviation estimates of the input and output random signals of the actual and differentiator filters under different noise are given in ...
This chapter provides a means of estimating the static stiffness of ball bearings subject to different mounting arrangements and types of load; a basic understanding of the mechanisms that influence damping and to provide guidance on the selection of damping coefficient; a basic understanding of the ...
