Description
Technical Field
The utility model relates to the technical field of mechanical oil seals.
Background
Oil seals are mechanical elements used to seal grease (oil is the most common liquid substance in transmission systems, also referred to generally as liquid substance meaning) and isolate the components of the transmission components that require lubrication from the output components, and prevent oil leakage.
Traditional oil blanket structure mostly can not play comparatively qualified sealed effect, and traditional oil blanket can produce wearing and tearing to the pivot simultaneously, influences sealed effect.
Disclosure of Invention
In order to solve the problem of poor sealing performance of the traditional mechanical oil seal, the utility model provides a single static ring type mechanical oil seal.
The technical scheme adopted by the utility model for achieving the purpose is as follows: the single static ring type mechanical oil seal is characterized in that the outer side of a static ring 1 is fixedly connected with an end cover 6, the static ring 1 is sleeved on a rotating shaft 7, a sealing groove is arranged on the inner side of the static ring 1, and a sealing ring is arranged in the sealing groove.
The inner side of the stationary ring 1 is provided with a second sealing groove 21 and a third sealing groove 41, a second sealing ring 52 is arranged in the second sealing groove 21, and a third sealing ring 53 is arranged in the third sealing groove 41.
The contact part between the outer side of the static ring 1 and the end cover 6 is provided with a first sealing groove 11, and a first sealing ring 51 is arranged in the first sealing groove 11.
The front end of the stationary ring 1 is integrally formed with a positioning boss 9, the outer diameter of the positioning boss 9 is larger than the size of a positioning groove 12 of the stationary ring 1, and the positioning boss 9 and the rear end of the stationary ring 1 are positioning grooves 12.
The first sealing ring 51, the second sealing ring 52 and the third sealing ring 53 are all rubber elastic members.
According to the single static ring type mechanical oil seal, the first sealing ring can completely seal the gap between the static ring and the end cover, and grease can be completely prevented from leaking outwards from the gap between the static ring body and the end cover; the second sealing ring can completely seal the gap between the stationary ring and the rotating shaft, and can completely prevent grease from leaking outwards from the gap between the movable ring and the rotating shaft; and the third sealing ring seals the gap between the static ring and the rotating shaft, so that the possibility that grease flows outwards from the gap between the static ring and the rotating shaft is reduced.

In the figure: 1. the device comprises a static ring, 11, a first sealing groove, 12, a positioning groove, 21, a second sealing groove, 41, a third sealing groove, 51, a first sealing ring, 52, a second sealing ring, 53, a third sealing ring, 6, an end cover, 7, a rotating shaft, 9 and a positioning boss.
Detailed Description
The single static ring type mechanical oil seal disclosed by the utility model is shown in figures 1-3, and comprises a static ring 1, wherein sealing elements 51, 52 and 53 are arranged on the static ring 1.
Referring to fig. 1 and 2, a stationary ring 1 is fixedly connected with an end cover 6, one end of the stationary ring 1 is provided with an integrally formed positioning boss 9, the outer diameter of the positioning boss 9 is larger than the installation size (the size of a positioning groove 12) of the stationary ring body 1, the corner between the positioning boss 9 and the stationary ring 1 is a positioning groove 12, the end cover 6 is abutted by the positioning groove 12, and the stationary ring 1 is in sealing connection with a rotating shaft 7.
Referring to fig. 2 and 3, the sealing member includes a first sealing ring 51, the first sealing ring 51 is coaxially sleeved outside the stationary ring 1, a first sealing groove 11 is formed on the groove wall of the positioning groove 12, the first sealing ring 51 is located in the first sealing groove 11, and the outer annular wall of the first sealing ring 51 abuts against the inner annular wall of the end cover 6. The first seal ring 51 can completely seal the gap between the stationary ring 1 and the end cover 6, and completely prevent grease from leaking out of the gap between the stationary ring 1 and the end cover 6.
The sealing element comprises a second sealing ring 52, the second sealing ring 52 is coaxially sleeved outside the rotating shaft 7, the inner annular wall of the stationary ring is provided with a second sealing groove 21, and the second sealing ring 52 is positioned in the second sealing groove 21. The second sealing ring 52 can completely seal the gap between the stationary ring 1 and the rotating shaft 7, and completely prevent grease from leaking out of the gap between the stationary ring 1 and the rotating shaft 7.
The inner annular wall of the stationary ring 1 is provided with a third sealing groove 41, a third sealing ring 53 is sleeved in the third sealing groove 41, and grease is completely prevented from leaking outwards from a gap between the stationary ring 1 and the rotating shaft 7.
Referring to fig. 3, the first seal ring 51, the second seal ring 52, and the third seal ring 53 are elastic members made of rubber or the like.
The implementation principle of the single static ring type mechanical oil seal provided by the embodiment of the utility model is as follows: when the oil seal is assembled, the first sealing ring 51 is sleeved in the first sealing groove 11, the third sealing ring 53 is sleeved in the third sealing groove 41, then the second sealing ring 52 and the static ring are sleeved on the rotating shaft 7, and finally the whole oil seal is pressed in the end cover 6, so that the positioning groove 12 is abutted against the end cover 6.
