These fluid waves pump lubricant into the engaged sealing interface when the shaft spins.

    The introduction of skeleton
    oil seals
    Generally said that the oil seal refers to the skeleton oil seal.The function of the oil seal is generally to isolate the parts that need lubrication in the transmission parts from the external environment, so as not to let the lubricating oil leak.The skeleton acts like the steel bars in a concrete member to strengthen and keep the seal in shape and tension.According to the structure, it can be divided into single lip skeleton oil seal and double lip skeleton oil seal.The auxiliary lip of the double lip skeleton oil seal plays a dust-proof role, to prevent the outside dust, impurities and so on into the machine.According to the frame type, it can be divided into inner frame oil seal, exposed frame oil seal and assembled oil seal.According to working conditions, it can be divided into inner frame oil seal, exposed frame oil seal and assembled oil seal.According to working conditions, it can be divided into rotating frame oil seal and round-trip frame oil seal.Used for gasoline engine crankshaft, diesel engine crankshaft, gearbox, differential, shock absorber, engine, axle and other parts.

    The skeleton oil seal structure is composed of three parts: oil seal body, strengthening framework and self-tightening spiral spring.The sealing body is divided into the bottom, waist, cutting edge and sealing lip according to different parts.Generally, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain amount of interference.

    Therefore, when the oil seal is loaded on the oil seal seat and shaft, the pressure on the edge of the oil seal and the contraction force of the self-tightening spiral spring produce a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease and even disappear. Therefore, the self-tightening force of the oil seal can be compensated at any time with the spring.

    HB bsetseals specialized in producing TC, SC, TG, TB, TA, DC, TCV, TCN, cassette, combi oil seals. The oil seals quality is very good and approved by customers from all over the world. We also can make mold for non-standard type and dimensions of oil seals.
