RISAnalysis of Static and Dynamic Characteristic of Hydrostatic Spherical Hinge
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new hydrostatic spherical hinge is developed in this paper to provide a large load capacity. The static and dynamic Reynolds equations in spherical coordinate system for incompressible Newtonian fluid were established ...
Analysis of the Static Characteristics of a Self Compensation Hydrostatic Spherical Hinge
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This technical brief presents a new selfcompensation hydrostatic spherical hinge to provide a large load capacity. The hinge consists of an upper part with selfcompensation and a lower part with orifice restrictors. A ...
Cavitation Erosion Resistance of Silicified Graphite by Liquid Silicon Penetration Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This technical brief studied the cavitation erosion behavior of the silicified graphite. The phase constituents, surface microstructure, and chemical compositions of silicified graphite were examined by using X-ray diffraction ...
Dynamic Analysis of a Motorized Spindle With Externally Pressurized Air Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this paper is to investigate the dynamic characteristics of a motorized spindle with externally pressurized air bearings. The externally pressurized air bearings consist of a journal bearing and a double pad ...
Research on Thermal Characteristics of Spindle System With Tilting Pad Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Spindles with tilting pad bearings have been widely applied in machine tools due to their high running precision. However, friction power loss will increase dramatically when the bearing runs at a higher speed. So far, ...
Dynamics of Flywheel Energy Storage System With Permanent Magnetic Bearing and Spiral Groove Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Developing a flywheel energy storage system (FESS) with permanent magnetic bearing (PMB) and spiral groove bearing (SGB) brings a great challenge to dynamic control for the rotor system. In this paper, a pendulum-tuned ...
Study of the Stiffness Matrix of Preloaded Duplex Angular Contact Ball Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper studies the stiffness characteristics of preloaded duplex angular contact ball bearings. First, a five degrees-of-freedom (5DOF) quasi-static model of the preloaded duplex angular contact ball bearing is established ...
Rotordynamics of an Improved Face-Grinding Spindle: Rotational Stiffness of Thrust Bearing Increases Radial Stiffness of Spindle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The support is a key factor affecting performance of face-grinding spindle. However, advantage of traditional rolling element bearing is not highlighted when it is for large-size face grinding. This technical brief aims ...
Comparative Study on Static Characteristics of Double-Pad Inwardly and Outwardly Pumping Water-Lubricated Spiral-Groove Thrust Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this technical brief is to investigate comparatively the static characteristics of the double-pad inwardly pumping and outwardly pumping water-lubricated spiral-groove thrust bearings (SGTBs). Firstly, a ...
Static Characteristics of High-Speed Water-Lubricated Journal Bearing Considering Turbulence and Cavitation Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The water-lubricated bearings tend to be turbulent and cavitating when running at a high speed. However, the modeling of the water-lubricated bearing considering the turbulence and cavitation effects has not been studied ...
