| Abstract | Hydrostatic bearings used in the grinding wheel spindles of grinding machines have high stiffness and high damping against load fl uctuation, as well as high rotating accuracy during grinding, however have larger power loss than other types of bearing. Therefore, the mechanism of power loss is elucidated using fl uid analysis and a hydrostatic bearing with minimal power loss is developed. As a result, a developed bearing has reduced power loss by 24%. |
