Problems solved by technology
Most of the seals in the prior art adopt fixed comb teeth seals, which use the tiny gap between the seal teeth and the rotating shaft to prevent the lubricating oil from leaking outwards.
However, the current problem of the comb seal is that due to the vibration of the shaft system, it is easy to damage the adjusted sealing gap, resulting in a large amount of lubricating oil leaking, wasting a lot of lubricating oil, and polluting the environment. prone to fire
In addition, the friction between the sealing teeth and the shaft will also wear the surface of the shaft, increase the maintenance cost of the unit, and bring great hidden dangers to the safe operation of the unit

Embodiment approach
[0052] Depend on figure 1 The shown oil seal mechanism is installed between the bearing box body 1 (including the case where the bearing box and the cylinder parts such as the cylinder are integrated) and the rotating shaft 5 to realize the oil seal between the two parts, which includes one or more Each oil seal unit is composed of a static seal ring 3 fixedly installed on the box body 1 and a dynamic seal ring (4) installed inside the static seal ring, and the two seal rings are set side by side in the axial direction On the rotating shaft but does not rotate with the shaft, the outer surface of the dynamic sealing ring and the inner surface of the static sealing ring can move relative to each other in the radial direction under the action of the magnetic attraction force of the magnetic connector 41, but the two do not rotate with the shaft, resulting in The oil film in the matching gap d1 between the dynamic sealing ring 4 and the rotating shaft 5 will be magnetized under t...

The invention relates to an oil seal mechanism. According to the oil seal mechanism, a dynamic sealing ring and a static sealing ring are connected by attracting through a magnetic connecting part, a magnetic source is provided by a magnetic oil screen of a ring gap between the dynamic sealing ring and a rotary shaft, a sealing gap has a following performance along with the shaft under the magnetic attracting function of a magnetic column, the concentricity of a float ring and the shaft is guaranteed, and the sealing effect is excellent; meanwhile the oil seal mechanism is better in oil seal effect due to a design of a blocking portion on the rotary shaft, a design of a spiral groove in the peripheral surface of the dynamic sealing ring, a design of a dynamic groove or a dynamic rib at the internal circumferential surface of the dynamic sealing ring, a design of a diversion arm on the static sealing ring and a design of a collection groove in the dynamic sealing ring.
Description
technical field [0001] The invention relates to an oil seal mechanism installed between a casing with a shaft hole (such as a bearing box cover) and a rotating shaft inserted into the shaft hole, especially the shaft end oil seal of the bearing seats at both ends of the rotating shaft of a high-speed machine. Background technique [0002] The bearings of existing high-speed machinery mostly adopt a sliding bearing pad support structure, and there is a large amount of lubricating oil in the bearing box. With the rotation of the rotor, the lubricating oil in the bearing box splashes and flows in the bearing box. [0003] In order to prevent the lubricating oil in the bearing box from leaking outwards, oil seals need to be provided at both ends of the bearing box. Most of the seals in the prior art are fixed comb teeth seals, which use the tiny gap between the seal teeth and the rotating shaft to prevent the lubricating oil from leaking outwards. However, the current problem o...
