μ Control of a High Speed Spindle Thrust Magnetic Bearing

Experimental results demonstrate that μ synthesis provides an excellent tool for increasing the dynamic stiffness of thrust magnetic thrust bearings. Accurate system modeling and appropriate uncertainty descriptions are critical to obtaining such results and are described in detail. Both complex μ and mixed μ synthesis were used to design controllers. The performance of the μ controllers is com...

Tapered Roller Bearings Cage to Improvement Design

In order to improve the utilization of materials, improving stamping cage processing methods, the single row tapered roller bearing cage is improved from structural strength, puts forward whole stamping cage a type of structure. Use ANSYS finite element analysis to the different structure and the thickness cage. Get the stress contours of the cage, based on equal strength design principles. Get...

Comparison of Bearings --- For the Bearing Choosing of High-speed Spindle Design

There are many types of bearings available, each used for different purposes and different conditions. Two major types of bearings are contact bearings and noncontact bearings. By considering the ball material, I separate the contact bearings to steel bearings and ceramic ball bearings. On the other hand, there are bearings that can run without any contact between the sliding surfaces in the be...

Numerical Analysis of Grease Film Characteristics in Tapered Roller Bearing Subject to Shaft Deflection

The shaft deflection is one of critical factors that deteriorate the grease lubrication state inside the tapered roller bearings (TRBs). So, in this paper, on the premise of the TRB subjected to the combined loads and the shaft is deflected, the grease lubrication model at the TRB contacts was constructed, in which the interaction loads, linear and angular displacements of the bearing parts wer...
