Description

Technical Field

[0001] The utility model relates to the technical field of floating oil seals, in particular to a floating oil seal pressing tool. Background Art

[0002] Floating oil seal is a common name for floating seal. It is a kind of mechanical seal in dynamic seal. It is mainly used for end face sealing under low speed, heavy load and harsh working conditions. It has super strong sealing performance in harsh working environments such as coal powder, mud, water vapor, etc. It is a compact mechanical seal. It has the advantages of strong anti-pollution ability, wear resistance, impact resistance, reliable operation, automatic compensation of end face wear and simple structure. Floating oil seal is mainly composed of fixed ring, floating ring, spring and sealing device. Its working principle is that when the equipment shaft rotates, lubricating oil is injected into the encapsulation cavity. There is a certain friction between the equipment shaft and the floating oil seal, so that the floating ring always keeps in contact with the equipment shaft. In the process of relative movement between the floating ring and the shaft, the lubricating oil is pumped to the outside of the shaft through the gap of the encapsulation cavity to form an oil film. The contact between this oil film and the shaft can form a lubricating oil seal to block external air and impurities from entering the equipment and prevent lubricating oil leakage. The spring of the floating oil seal enables the floating ring to adapt to shaft deformation and axial displacement caused by other factors. Floating oil seals are widely used in engineering machinery, coal mining machinery, various conveyors, sand processing equipment, concrete equipment and other fields. For example, bulldozer travel mechanism, scraper conveyor head sprocket assembly, tunneling machine loading mechanism and cantilever section, continuous coal mining machine left and right cutting drum and reducer, etc. In addition, some construction machinery, loaders, graders, cranes, mixers, and mining machines are also used.

[0003] At present, the existing floating oil seal pressing tool needs to be adjusted and pressed by the pressing tool when pressing the floating oil seal. The current method of adjusting the pressing is that the operator manually operates the pressing tool to fix it. Manual operation is not only too laborious, but also affects the convenience of the operator. Therefore, a floating oil seal pressing tool is proposed to solve the above problem.
