the middle part of the outer wall of the bearing 2 is provided with the oil dipping ring 21, the width of the oil dipping ring 21 is gradually decreased from inside to outside in an arc shape and rotates along the annular groove 11, the oil dipping ring 21 on the outer wall of the bearing 2 firstly dips the lubricating oil overflowing from the oil dipping port 13 in the rotating process, the heat of the lubricating oil in the rotating process can be increased, when the lubricating oil passes through the oil discharging port 14, the adhered part of the high-heat lubricating oil can be thrown out, and the lubricating oil continuously dips and throws out the part of the high-heat lubricating oil in the rotating process, so that the heat of the lubricating oil between the bearing 2 and the fixed seat 1 is reduced, the hot grinding between the bearing 2 and the fixed seat 1 is reduced, and the service life of the bearing is prolonged.
In this embodiment, the oil dipping port 13 is close to the vertical central axis of the fixing seat 1, and the position of the oil dipping port 13 is lower, so that excessive lubricating oil does not need to be added in the oil groove 12.
In this embodiment, the upper opening of the lower oil port 14 is in an outward expansion structure, so that lubricating oil thrown out from the outer wall of the bearing 2 can flow out through the lower oil port 14.
