Germany CFW oil seal 40 * 62 * 6

Germany oil seal oil seal oil seal is typical, the general said, referring to the oil seal oil seal. The role of oil seals in general is part of the drive components need lubrication and output components isolation, and will not allow oil leakage. Like skeleton reinforced concrete structures inside, serve to strengthen the role and seal to maintain the shape and tension. Form of the structure can be divided into single-lip oil seal and oil seal lips. Vice-lip oil seal lips played the role of dust, to prevent outside dust and impurities into the inside of the machine. Skeleton type can be divided according to package seal, and seal the exposed skeleton oil seal assembly. According to the working conditions can be divided into rotating and reciprocating oil seal oil seal. For gasoline engine crankshaft, diesel engine crankshaft, transmission, differentials, shock absorbers, engines, axles and other parts. (1) shaft rotational speed due to the design and structure, high speed shaft seals should use high-speed, low-speed low-speed shaft seal can not be used for low-speed shaft seal, nor vice versa. (2) the ambient temperature in the case of higher temperatures, should be used polyacrylate or silicon, fluorine, silicon fluorine rubber. And should seek to reduce the oil in the tank. In the case where the temperature is too low, and should be used cold-resistant rubber. (3) the seal pressure is generally poor ability to withstand pressure, excessive pressure seal will be deformed. Under the conditions of use excessive pressure should withstand the pressure seal support ring or strengthened. (4) with the eccentric eccentricity and shaft seal installation is too large, then the seal will deteriorate, especially at high speed when the shaft is particularly serious. If eccentricity is too large, it can seal "W" shaped cross section. Surface finish (5) shaft seal directly affect the life of an axis high finish, seal life on the president. (6) Note that the seal lip should be a certain amount of lubricating oil. (7) to pay special attention to prevent dust immersion oil seal.
