Problems solved by technology

Traditionally, the journal / bearing shell of the tapered spiral groove bearing is often made of steel / copper material, however, for a rotor system with a large load, the power consumption of the tapered spiral groove will increase significantly
In order to overcome the problem of increased power consumption caused by the increase of bearing load, low-viscosity lubricating oil can be used for lubrication. However, reducing the viscosity of lubricating oil will increase the speed at which the bearing achieves full fluid lubrication, which will cause serious problems during the startup or shutdown phase of the bearing. Wear problems, reduced life

Embodiment 1

[0028] Embodiment 1: a kind of floating bearing, refer to Figure 1-2 , including main shaft 2, one-way valve 1 and auxiliary floating shaft 4.

[0029] The one-way valve 2 is provided with a first oil storage chamber 101, a second oil storage chamber 102, a valve front chamber 103 and a valve rear chamber 104. The one-way valve 1 includes a valve body 11, a valve core 12 and a compression spring 13. Normally ( That is, when the pressure difference between the valve front chamber 103 and the valve rear chamber 104 is not greater than the opening pressure of the check valve 1), the compression spring 13 pushes the valve core 12 to connect with the valve body 11, and the valve front chamber 103 is isolated from the valve rear chamber 104. Check valve 1 is closed. When the pressure difference between the valve front chamber 103 and the valve rear chamber 104 is greater than the opening pressure of the check valve 1, the lubricating oil in the valve front chamber 103 pushes the v...

Abstract

The invention discloses a floating-assisted type bearing and a using method thereof. The bearing comprises a main shaft, a one-way valve and a pressurizing floating-assisted device. A first oil storage cavity, a valve front cavity and a valve rear cavity are formed in the one-way valve, and a valve element of the one-way valve is used for enabling lubricating oil in the valve front cavity to enter the valve rear cavity in a one-way mode. The main shaft and the one-way valve are rotatably connected to form a conical surface bearing, a first pumping type groove is formed in the connecting conical surface of the main shaft and the one-way valve, and when the main shaft rotates, the lubricating oil in the first oil storage cavity is pumped into the valve rear cavity. And an output port of the pressurizing floating-assisted device is communicated with the valve front cavity through a pipeline and is used for opening the one-way valve. In the starting or halting stage of the main shaft, the pressurizing floating-assisted device is started, so that an oil film is formed on the connecting conical surface of the main shaft and the one-way valve, and the friction force of the conical surface spiral groove bearing in the starting or halting stage is reduced.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a buoyancy-assisted bearing and a use method thereof. Background technique [0002] The tapered spiral groove bearing is a kind of fluid lubricated bearing, which is often used in high-speed vertical rotor systems, such as energy storage flywheel systems, to obtain lower frictional power consumption. Traditionally, the journal / bearing shell of the tapered surface spiral groove bearing is often made of steel / copper material. However, for a rotor system with a large load, the power consumption of the tapered surface spiral groove will increase significantly. In order to overcome the problem of increased power consumption caused by the increase of bearing load, low-viscosity lubricating oil can be used for lubrication. However, reducing the viscosity of lubricating oil will increase the speed at which the bearing achieves full fluid lubrication, which will cause serious problems du...
