A smooth damping lubricating bearing

Abstract

The invention discloses a stable shock-absorbing and lubricating bearing which comprises a bearing seat and a spindle. The spindle is mounted in the bearing seat, and the two ends of the spindle penetrate through bearing caps respectively. Sealing rings are further arranged at the fit positions of the bearing caps and the bearing seat. A balance spring is arranged at the connection position of each bearing cap and the spindle. Wear-resisting rings are arranged on the middle part, mounted in the bearing seat, of the spindle. Compression springs are arranged between the wear-resisting rings. The parts, mounted in an inner cavity of the bearing seat, of the wear-resisting rings are fixed through wear-resisting plates. Shock-absorbing rings are further arranged between the bearing seat and the spindle, an oil guiding pipe is arranged on the bearing seat, one end of the oil guiding pipe stretches into the bearing seat, and the other end of the oil guiding pipe stretches out of the bearing seat and is sealed by a sealing cover. By means of the scheme, a well sealing effect can be achieved, the spindle can also be stably lubricated, shock of a machine is reduced, and the service life of the machine is prolonged.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a smooth damping 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 stable vibration-absorbing lubricated beari...

[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.
