Leakage-proof lubricating bearing

Abstract

The invention discloses a leakage-proof 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. A sealing clamping seat is arranged on the part, mounted in the bearing seat, of the spindle. Sealing rings are further arranged at the positions where the bearing caps and the bearing seat are matched. Gaps are formed between the sealing clamping seat and an inner cavity of the bearing seat. 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. According to the scheme, flowing-in of engine oil in the lubricating process is facilitated through the gaps between the spindle and the sealing clamping seat; the sealing rings are arranged at the positions where the bearing caps and the bearing seat are matched, so that the sealing and leakage preventing effects are further achieved; the oil guiding pipe facilitates lubricating operation, and the spindle can be lubricated after the sealing cover is opened and lubricating oil is added. Through the design, consumption of the engine oil can be reduced, sealing and leakage preventing of the bearing can be well achieved, meanwhile, lubrication of the spindle is guaranteed, and the service life of the spindle is prolonged.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a leak-proof lubricating bearing. Background technique [0002] Centrifugal fans are a large class of general-purpose equipment widely used in industrial production. At present, the shaft seals of centrifugal fans mostly use sealing elements such as packing seals or skeleton oil seals. Since the sealing elements are fixed on the housing, there is a relative gap between the sealing elements and the main shaft. Therefore, when the equipment runs continuously for a long time, the sealing elements are easy to wear and leak, and frequent shutdowns are required for processing, which 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 leak-proof lubricating bearing with good sealing effect. [0004] The technical solution of the pre...
