摘要： A high-speed hydrodynamic spindle assembly with an axialreciprocation or tacking movement, in which the spindle comprises, in the vicinity of one of its hydrodynamic bearings, a collar which is displaced between two rings and to which is transmitted the hydraulic pressure of the lubricating fluid of the bearings, so as to cause the tacking movement of the spindle, the pressure of the fluid and its regulation being obtained by an appropriate distribution device of the lubricating circuit of the bearings of the spindle.

摘要： A fluid dynamic pressure bearing includes a conical bearing member having a conical bearing surface forming a first gap between a member constituting the rotor. A second gap connected to one end of the first gap and provided over the entire periphery of the shaft is formed between the conical bearing member and the shaft. A tapered seal portion is formed between the conical bearing member and the rotor. The conical bearing member is provided with a circulation hole that communicates the second gap and the tapered seal portion. The circulation hole communicates to another end of the first gap through a part of the tapered seal portion, so that the circulation hole and the other end of the first gap are spaced apart.

摘要： The object of the present invention is to suppress a mechanical loss caused by thermal elongation or rotational vibration of a rotary shaft of a turbo compressor for compressing a low pressure refrigerant used at a maximum pressure of less than 0.2 MPaG so as to enhance the efficiency of a turbo chilling apparatus. The turbo compressor is a turbo compressor for compressing a low pressure refrigerant used at a maximum pressure of less than 0.2 MPaG, the turbo compressor including: a rotary shaft; an electric motor coaxially disposed on an intermediate portion of the rotary shaft so a to rotationally drive the rotary shat impellers fixed to one end of the rotary shaft and forming a compression portion; a first bearing pivotally sporting the rotary shaft between the electric motor and the impellers; and a second bearing pivotally supporting the other end of the rotary shaft, wherein the first bearing is formed of a rolling bearing, and the second bearing is formed of a sliding bearing.

摘要： A spindle unit for a machine tool for fine-machining workpieces having groove-shaped profiles, has a rotatably mounted spindle shaft (2). The spindle shaft is subdivided in the axial direction (AR), one behind the other, into a fastening portion (A) for fastening a tool (4) or a workpiece to be machined, a first bearing portion (B), a force transmission portion (C), and a second bearing portion (D). A drive unit (5) serves to drive the spindle shaft by way of force transmission onto the force transmission portion. A first and a second bearing point (13, 14) are designed to bear the spindle shaft in the first bearing portion, and a third bearing point (15) serves to mount the spindle shaft on the second bearing portion. The first and the second bearing points each have one or more hydrostatic bearings. The third bearing point has one or more hydrostatic and/or hydrodynamic bearings.
