Problems solved by technology
Due to the centrifugal force generated when the shaft core is running, the lubricating oil will be thrown out along the outer wall of the shaft core, and then leak from the gap between the cover and the shaft core; and due to the long-term friction between the shaft core and the bearing to generate heat, The powder inside the bearing will expand due to heat, which will reduce the pores in the bearing, and then squeeze out the lubricating oil to volatilize or even deteriorate; the leakage and volatilization of lubricating oil will increase the wear between the shaft core and the bearing, and greatly reduce the wear of the bearing. The lubrication function of the system, what's more, the shaft core and the bearing will be stuck, which seriously affects the working life of the bearing system

The invention discloses a bearing system. The bearing system comprises a shaft core installed on a rotor cover. A bearing rotating relative to the shaft core is arranged on the shaft core. A sealing cap arranged on the shaft core in a surrounding mode is arranged between the bearing and the rotor cover. A gap is formed between the sealing cap and the shaft core. A bearing annular groove is formed in the inner side face of the bearing. Protruding parts are formed on the two sides of the bearing annular groove to make contact with the shaft core. A shaft core annular groove is formed in the shaft core located between the two protruding parts. An oil storage space is formed between the shaft core annular groove and the bearing annular groove. Circular arc transition is arranged at the edge of the shaft core annular groove. According to the bearing system, lubricating oil is gathered onto the bearing face between the bearing and the shaft core through guiding of the circular arc transition, so that the space between the bearing and the shaft core is fully lubricated. Accordingly, friction force in the rotation process is reduced and the service life of the bearing system is prolonged.
Description
technical field [0001] The invention relates to a bearing system. Background technique [0002] Bearings generally have a porous structure, which is mainly made of copper powder, iron powder and other powder mixed with lubricating grease. The function of the bearing is to support the mechanical rotating body to reduce the friction coefficient during the operation of the equipment and ensure its rotation accuracy. [0003] The existing bearing system includes a shaft core installed on the rotor cover, a relative rotating bearing is arranged on the shaft core, a cover surrounding the shaft core is provided between the bearing and the rotor cover, and the gap between the cover and the shaft core is There is a gap in between. Due to the centrifugal force generated when the shaft core is running, the lubricating oil will be thrown out along the outer wall of the shaft core, and then leak from the gap between the cover and the shaft core; and due to the long-term friction between...
