Problems solved by technology

However, this is not the case in actual applications. Lubricating oil often seeps out from the sealing ring at the transmission shaft, which not only wastes lubricating oil, but also brings great troubles to the appearance of the equipment and the environmental sanitation and maintenance of the site.

Abstract

The invention relates to a seal structure, in particular to a transmission shaft seal structure. The structure is composed of a large gear, a small gear, an oil blocking ring, a seal support, a lip-shaped seal ring and a transmission shaft; in the technical scheme, a thread structure is machined on the proper position of the transmission shaft, rotation of the transmission shaft drives lubricating oil deposited in the thread portion on the transmission shaft to move inwards, overflowing lubricating oil returns to a reserved flowing rail again, and due to the combination manner of the lubricating oil and the lip-shaped seal ring, seal between the transmission shaft and the small gear is more reliable; meanwhile, the lubricating oil can be prevented from seeping out, lubricating oil waste is avoided, and the advantages of being simple in structure, clean and sanitary are achieved.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a transmission shaft sealing structure. Background technique [0002] Tube mill is a kind of pulverizer, and it is also a very important fine grinding equipment in modern industry. It is a cylinder with supporting devices at both ends, which contains grinding bodies or grinding media; the cylinder rotates around the horizontal central axis, the grinding media is brought to a certain height by friction and then falls, and the material passes through the cylinder continuously , so that it is continuously impacted, extruded and ground by the grinding medium, and finally ground into a qualified product; the tube mill is widely used in building materials, metallurgy, mineral processing, electric power and chemical industries to grind cement and other materials; it has a large crushing ratio, production It has the characteristics of large capacity, strong adaptability to materials, and easy repl...
