A smoothly lubricated bearing

Abstract

The invention discloses a smooth lubricating bearing, which comprises a bearing seat and a main shaft; the main shaft is installed in the bearing seat, and the two ends pass through the bearing cover respectively; a sealing ring is also provided at the matching place of the bearing cover and the bearing seat; A balance spring is provided at the joint between the bearing cover and the main shaft; a wear-resistant ring is provided at the middle part of the main shaft installed in the bearing seat; a compression spring is provided between the wear-resistant rings; the wear-resistant ring is installed on The part in the inner cavity of the bearing seat is fixed by a wear-resistant plate; the bearing seat is provided with an oil guiding pipe; one end of the oil guiding pipe extends into the bearing seat, and the other end extends out of the bearing seat and is sealed by a sealing cover; the solution of the present invention is adopted The above design can not only play a good sealing effect, but also play a role in stabilizing the main shaft.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a smooth lubricating bearing. Background technique [0002] Fans are a large class of general-purpose equipment widely used in industrial production. At present, the shaft seals of fans mostly use sealing elements such as packing seals or skeleton oil seals. Since the sealing elements are fixed on the housing, there is relative movement between the sealing elements and the main shaft. This makes the machine unstable, prone to shaking and causing certain damage to the machine. When the machine is running continuously for a long time, the sealing elements are prone to wear and leakage, and frequent shutdowns are required. This is not only labor-intensive, but also seriously affects production efficiency. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a smooth lubricating bearing that can reduce machine ...

[0002] Fans are a large class of general-purpose equipment widely used in industrial production. At present, the shaft seals of fans mostly use sealing elements such as packing seals or skeleton oil seals. Since the sealing elements are fixed on the housing, there is relative movement between the sealing elements and the main shaft. It makes the machine unstable, prone to shaking and causing certain damage to the machine. When the machine is running continuously for a long time, the sealing element is easy to wear and leak, and it needs to be shut down frequently, which is not only labor-intensive, but also seriously affects production efficiency.
