The invention discloses a split type static pressure sliding bearing sliding device. The support block is connected with the base and supports the guide rail, the bearing seat is connected with the sliding platform, and the sliding bearing is nested in the bearing seat. The inner core, the guide rail passes through the inner core, the two ends of the jacket are provided with flanges for restricting the axial movement of the inner core, the inner core is provided with an annular oil chamber communicating with the pressure chamber, and the inner wall of the flange circumference is provided with an oil return Cavity and air-sealed cavity, the guide rail of the present invention is provided with support blocks for support, preventing the guide rail from being easily deformed under stress, with high operating accuracy, ensuring that the cylindrical guide rail will not rotate and axially move during operation, and at the same time provide Pre-tightening force, the three pressure chambers on the inner wall of the sliding bearing core are evenly distributed at 120°, with strong centering ability and reliable bearing capacity. The inner wall of the flange is equipped with an oil return chamber and an air seal chamber to ensure smooth oil return flow High-pressure air is used for sealing to ensure a clean and tidy working environment.
Description
technical field [0001] The invention relates to the field of sliding bearings, in particular to a split type static pressure sliding bearing sliding device. Background technique [0002] Sliding bearings are widely used in rotating machinery, and the common ones are hydrodynamic sliding bearings, hydrostatic sliding bearings and hydrodynamic and hydrostatic sliding bearings. Most of the hydrostatic bearings currently used are monolithic, which is difficult to process and high in cost; poor sealing of the bearings can easily cause oil leakage, waste oil and cause pollution, and further increase costs; in addition, the shape of traditional sliding bearings is complete The circular shape will completely wrap the circumferential surface of the cylindrical guide rail during operation, which causes the cylindrical rail to be unable to be effectively supported within the lead, and the rigidity is insufficient. It cannot be used under the conditions of long lead, high precision, and...
