The invention discloses a sealing tape air knife slitting machine hydraulics and pneumatics oil sealing sleeve used for stationery, which comprises an oil sealing sleeve body, wherein two O-shaped ring mounting positions are arranged on the oil sealing sleeve body, an oil sealing sleeve body stop collar is made integrally in the tail of the oil sealing sleeve body, a sealing element installation opening is arranged on the front side of the oil sealing sleeve body; the height of the oil sealing sleeve body is 28 mm, the external diameter of the oil sealing sleeve body is 110 mm, and the inner diameter of the oil sealing sleeve body is 85 mm; the two O-shaped ring mounting positions are arranged in the middle part of the oil sealing sleeve body, the breadths of the two O-shaped ring mounting positions are both 4 mm, the distance between the two O-shaped ring mounting positions is 4mm, the groove depths of the two O-shaped ring mounting positions are both 2.5 mm, and O-shaped rubber seal rings used for hydraulics and pneumatics are arranged inside the two O-shaped ring mounting positions respectively. The oil sealing sleeve used for hydraulics and pneumatics makes improvement on the basis of prior art, and has higher leakproofness. The breadths of the O-shaped rubber seal rings are a little broader than those of the groove depths to guarantee that the O-shaped rubber seal rings are closely installed with the telescoping ends of telescoping components. The sealing tape air knife slitting machine hydraulics and pneumatics oil sealing sleeve used for stationery is capable of adapting to complex working environment.
Description
technical field [0001] The invention relates to an oil seal cover, in particular to a hydraulic and pneumatic oil seal cover for an adhesive tape air knife slitting machine for stationery, and belongs to the technical field of adhesive tape equipment parts. Background technique [0002] Oil is the most common liquid substance in the transmission system. At the input and output ends of the transmission system, oil seals are generally required to seal the oil. It isolates the parts that need to be lubricated from the output parts in the transmission parts, so as not to let the lubricating oil seep Leakage; and the oil seal generally needs to be installed through the oil seal sleeve to cooperate with the structure of the transmission system. Hydraulic and pneumatic equipment is widely used in existing equipment. Hydraulic and pneumatic equipment includes high-pressure plunger pumps, gear pumps, vane pumps, general hydraulic valves, oil cylinders, oil-free lubricated pneumatic p...
