have gone through journal bearing test.Lubrication and abrasion characteristics were evaluated by analyzing the material characteristics of a bearing bush in a scroll compressor.Al alloy bearings had an effect of lowering the friction coefficient by 28% than Cu-Sn alloy bearings under high load ...
In the method for simultaneously determining the course (trend) and the absolute position of the characteristic, and for determining the static and the dynamic spring constants (stiffness) as well as the position and shape of the hysteresis surface of a rubber bearing with continuous recording of ...
Fascism, political ideology and mass movement that dominated central, southern, and eastern Europe between 1919 and 1945 and was characterized by extreme militant nationalism, hatred of communism and socialism, contempt for democracy, and belief in natur
There may well be this case that a trade-off between stability, unbalance and shock vibration reduction performances exists. So this research aims to synthetically study the effects of support stiffness and damping on dynamic characteristics of the rotor-gas foil bearing system, i.e., stability, ...
The forces acting on the moving part of a pneumatic linear bearing in the stationary state and during motion are difficult to measure directly because they are very small. Methods for measuring static and dynamic frictional characteristics of a pneumatic linear bearing in which the acceleration due ...
In a coal mine in the northern region of Shaanxi Province, China, a facing-mining excavating roadway exists, which is intended to be retained for subsequent working face safety services. This paper investigates the deformation and damage characteristics
Up to now, most research work on DLC coating have been carried out at fairly low wear loads, usually much lower than 10 N, which may not meet the needs of the service requirement of high precision ball bearing and automotive parts that are often subjected to high applied load and elevated...
This study investigates the characteristics of a tapered roller bearing with bearing races that have geometric error. In particular, the out-of-roundness errors of the inner and outer races, which may occur during the manufacturing process or as a result of improper loadings, are considered. To ...
Large-scale sinistral strike-slipping faulting of the F2 fault played important roles on the convergence together of different segments of the Tanjianshan Group,and also the missing of some ore-bearing geological bodies. Field mapping between the Zhongjiangou and Wuminggou areas revealed that the ...
A Study on Efficiency of Tapered Roller Bearing for an Automatic Transmission Automotive fuel efficiency regulations and air pollution control are hot issues of recent years in the automotive industry. To solve these regulation problems, many studies are continuing to improve the transmission efficiency ...
