Abstract
The utility model discloses a novel structure is kept off to follow-up and clearance combination seal oil, the utility model discloses can block the influence of outside negative pressure effectively, prevent that the oil mist in the bearing oil groove from overflowing. The utility model discloses by metal oil fender, self-lubricating follow-up insulating seal tooth, sealed tooth, air supplement pipe, oil absorption fog pipe, axle constitution. The self-lubricating follow-up insulating seal teeth and the seal teeth can effectively prevent oil mist generated in the running process of the unit from diffusing to other parts of the unit.
Description
The technical field is as follows:
the utility model relates to a novel structure of follow-up and clearance combined seal oil fender.
Background art:
when the generator motor is operated, oil in the oil sump tends to form oil mist when the shaft rotates at a high speed, and the oil mist is diffused to the outside of the oil sump through a gap between the bearing and the shaft. The bearing below the unit rotor generates negative pressure outside an oil groove due to the rotation of the unit rotor, and the escape and diffusion of oil mist are intensified. The oil mist is condensed when being cooled outside the oil groove, and if the oil mist is condensed at key electrical parts such as a stator, a rotor and the like in an operating unit, dust is easy to adhere to the key electrical parts, the insulation performance of the unit is influenced, and even the safe and stable operation of the unit can be influenced. The sealing oil baffle of the traditional structure has an unobvious effect on solving the sealing problem between the rotating shaft and the fixed sealing oil baffle.
The invention content is as follows:
the utility model provides a can prevent effectively that oil mist diffusion in the oil groove from keeping off novel structure with clearance combination seal oil with a follow-up of effusion, technical scheme is: the metal oil baffle is provided with the air supplementing pipe and the oil mist absorbing pipe, the air supplementing pipe is arranged above the air supplementing pipe, the oil mist absorbing pipe is arranged below the air supplementing pipe, and the air supplementing pipe and the oil mist absorbing pipe are arranged in opposite directions.
The self-lubricating follow-up insulating seal tooth is composed of a plurality of self-lubricating insulating seal materials, all the self-lubricating follow-up insulating seal teeth are in natural lap joint, one side of each self-lubricating follow-up insulating seal tooth is installed in a groove processed by the metal oil baffle, and the other side of each self-lubricating follow-up insulating seal tooth is in contact with the shaft.
The sealing teeth are of multi-section ring structures, the inner diameter of each sealing tooth is slightly larger than the outer diameter of the shaft, the sealing teeth are riveted in grooves in the metal oil retainer, and the sealing teeth are made of red copper.
The metal oil baffle is made of cast aluminum alloy.
The servo insulation seal teeth of the self-lubricating material are in contact with the rotating unit rotating shaft, the self-lubricating material can effectively reduce the friction heating phenomenon, and the insulation characteristic can effectively cut off the conduction of shaft current which possibly occurs in the unit. The sealing teeth are made of red copper materials, are not in contact with the shaft during normal work, only play a role in reducing outward splashing of lubricating oil in the oil groove, and once scraping and colliding occur due to the fact that the rotating shaft has large swing, the sealing teeth cannot cause large damage to the shaft.
The technical effects are as follows:
compared with the traditional sealing oil baffle structure, the novel structure of the follow-up and clearance combined sealing oil baffle is added with a sealing tooth structure. The sealing tooth structure can more effectively block the influence of the negative pressure outside the oil groove and prevent the oil mist in the oil groove from diffusing and escaping.
The inner circle of the metal oil baffle adopts a double-cavity structure, the upper cavity is an air supplementing cavity, and the lower cavity is an oil mist absorbing cavity. When the unit operates, the self-lubricating follow-up insulating seal teeth can adapt to the throw of the shaft, and zero clearance sealing is realized. Self-lubricating follow-up insulating seal tooth blocks the influence of outside negative pressure with sealed tooth is multiple, prevents that oil mist in the oil groove from overflowing, can satisfy the requirement that the unit does not have the oil mist safe operation for a long time.
Description of the drawings:
fig. 1 is a section view of the novel structure of the servo and gap combined sealing oil baffle of the utility model.
The specific implementation mode is as follows:
as shown in figure 1, the utility model discloses a follow-up and clearance combination sealing oil keeps off novel structure. The novel structure of the follow-up and clearance combined sealing oil baffle is composed of a metal oil baffle 1, self-lubricating follow-up insulating sealing teeth 2, sealing teeth 3, an air supplementing pipe 4, an oil mist suction pipe 5 and a shaft 6. The metal oil baffle 1 is divided into an upper cavity and a lower cavity, and the self-lubricating follow-up insulating seal teeth 2 and the seal teeth 3 are arranged from top to bottom. The metal oil baffle 1 is provided with an air supplementing pipe 4 and an oil mist absorbing pipe 5. The air supply pipe 4 is arranged above, and the oil mist absorption pipe 5 is arranged below. The seal teeth 3 do not contact the shaft 6 during normal operation.
The air supply pipe 4 and the oil mist absorption pipe 5 are distributed oppositely. The oil mist suction pipe 5 and the air supplement pipe 4 can be externally connected with an oil mist suction device and a forced air supplement device.
