414 Sliding Bearing of Screw Compressors (20th Report) Sliding Thrust Bearing at the Bi-rotational Behavior Characteristics Ribbon thrust-bearing is the hydrodynamic. The hydrodynamic thrust-bearing, composed inflow type spiral-grooves combined with inner-radial-grooves for screw-compressor. At refrigerant-blended lubrication condition and bi-rotational operating condition is testing. Test results showed reliable and reasonable bearing-performance in terms of bearing-film -thickness, bearing-temperature and friction-torque.
D11 Sliding Bearing of Screw Compressors (21st Report) The Operating Characteristics of Flat Sliding Thrust Bearings by the Bi-Rotational. Of starting in rotation, injection lubrication of the refrigerant-blending lubricant oil was applied into reduce on friction-torque. Injection lubrication of the refrigerant-blending lubricant oil was applied into reduce on friction-torque. With the combination effectively of spiral-grooves and radial-grooves ones was to put on the slid runner surface. The depth of the each grooves are 0.10mm. The bearing is bearing-outer diameter φ80mm and bearing-inner diameter φ40mm.
E35 Sliding Bearing of Screw Compressors (22nd Report) : The Ribbon Bearing Type of the Bi-rotational Behavior Characteristics.
The ribbon-bearing is possible that the bi-rotational. Despite the parallel-plate-bearing of Ribbon-bearing , the bi-rotational and can to operator safely. Oil Film thickness and bearing temperatures and friction torque were tested measured. Synthetic-oil was used as the lubricant. The tests were carried using refrigerant-blended-lubricant. Refrigerant-blended-lubricant is blending-ratio of 6wt%, 10wt% and 44wt%. Simulate is the real state of the refrigerator-compressor. The ribbon-bearing is possible that the bi-rotational. Despite the parallel-plate-bearing of Ribbon-bearing , the bi-rotational and can to operator safely. Oil Film thickness and bearing temperatures and friction torque were tested measured.
