專利摘要(中)
A membrane restrictor adapted to be connected to a pump and a bearing is provided. The pump is adapted to supply fluid to a location between the bearing and the rail through the membrane. The bearing is adapted to be disposed on a rail. The membrane restrictor includes a casing and a membrane. The casing has a chamber, an inlet and an outlet communicating with each other through the chamber, and a restricting plane. The pump is adapted to be connected to the inlet; the bearing is adapted to be connected to the outlet. The membrane is disposed in the chamber. The restricting plane is an inner surface of the casing adjacent to the outlet and towards the membrane. Dimensionless stiffness of the membrane is Kr, and 1.33≦Kr≦2. Kr*=KrL0/(psAr). Here, Kr is stiffness of the membrane, L0 is a distance from the membrane to the restricting plane when no fluid is supplied by the pump (i.e., assembling clearance of the membrane), ps is pressure supplied by the pump, and Ar is an effective area of the restricting plane. A hydrostatic bearing module having the membrane restrictor is further provided.
