Problems solved by technology

Because the viscosity of air is much lower than that of lubricating oil, its bearing capacity is small, and it is not suitable for working conditions under complex loads, especially in gear transmission systems. The fluctuation of gear meshing force will affect the hi

Example Embodiment

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0029] As attached figure 1 As shown, the high-speed floating ring bearing-rotor system shown in this embodiment includes a lock nut 1, a centrifugal impeller 2, a sealing ring 3, a rotor 4, a high-speed floating ring bearing 5, an adjustment pad 6, a thrust plate 7, a floating ring and Thrust combined bearing 8. The high-speed floating ring bearing 5, the floating ring and thrust combined bearing 8 are sleeved on the two ends of the rotor system to support and transmit torque. The high-speed floating ring bearing 5 bears radial loads, and the floating ring and thrust combined bearing 8 bears radial and axial loads, which not only greatly saves installation space, and rationally arrange the layout of the bearings, but also meet the needs of the rotor system. strength.

Abstract

The invention discloses a high-speed floating ring bearing sleeving a rotor. The high-speed floating ring bearing comprises a bearing block and a floating ring. The bearing block is of a hollow cylinder structure. The floating ring is arranged in the hollow cylinder structure. When the rotor runs, the floating ring and the rotor relatively rotate, and the bearing block is provided with a bearing block oil passing hole and a bearing block oil passing groove. The floating ring is provided with a floating ring oil passing hole and a floating ring oil groove. Lubricating media enter the bearing block oil passing groove through the bearing block oil passing hole and enter the floating ring oil groove through the floating ring oil passing hole, and when the rotor rotates, a dynamic pressure oilfilm is formed to support the rotor. A high-speed floating ring bearing-rotor supporting system comprises the above high-speed floating ring bearing, and further comprises a floating ring and thrust combined bearing, a rotor system and an oil supply system.

Description

technical field [0001] The invention relates to a high-speed floating ring bearing, in particular to a high-speed floating ring bearing-rotor system support method. Background technique [0002] With the development of rotating machinery in the direction of high speed and high stability, higher requirements are put forward for support methods with large DN value, long life, impact resistance, and good high-speed stability. At present, high-precision rolling bearings, sliding bearings, magnetic levitation bearings and air bearings are mainly used in the support scheme of the rotor of the high-speed light-load transmission system. [0003] The DN value of the high-precision rolling bearing is 2×10 6 Below, once the limit speed of the bearing is exceeded, the bearing rollers will run abnormally under the action of centrifugal force, the life of the bearing will be greatly shortened, and the rotor will generate greater vibration. In severe cases, the bearing will be locked and ...
