技術簡介
液靜壓軸承總成包括一軸承及兩薄膜節流器。軸承適於可移動地配置在滑軌上,且包括兩子軸承部,對向地配置在該滑軌的相對兩側。兩薄膜節流器適於連接於泵。泵適於供應一流體經兩薄膜節流器流至兩子軸承部與滑軌之間,各個薄膜節流器包括一殼體及一節流薄膜片。殼體與對應的子軸承部的至少一者包括一腔室、連通於腔室的一入口與一出口、以及一出口平面,其中泵適於連接於入口,滑軌適於配置於出口旁。節流薄膜片位於腔室內,覆蓋在出口平面上。
Abstract
A hydrostatic bearing assembly including a bearing and two membrane throttles is provided. The bearing is adapted to be movably disposed on a slide rail and includes two sub-bearing portions that are disposed opposite to each other on two opposite sides of the slide rail. The two membrane throttles are adapted to be connected to a pump. The pump is adapted to supply a fluid through the two membrane throttles to flow between the two sub-bearing portions and the slide rail, and each of the membrane throttles includes a casing and a throttling membrane piece. At least one of the casing and the corresponding sub-bearing portion includes a chamber, an inlet and an outlet communicating with the chamber, and an outlet surface, wherein the pump is adapted to be connected to the inlet, and the slide rail is adapted to be disposed adjacent to the outlet. The throttling membrane piece is being positioned in the chamber covers on the outlet surface.
