Description
Technical Field
The utility model belongs to the field of machinery, especially, relate to epaxial floating oil blanket adjusts structure.
Background
At present, a sealing mechanism in heavy mechanical equipment adopts a floating oil seal and a sealing ring to prevent muddy water from entering and lubricating oil in a cavity from seeping out, and the floating oil seal has a better sealing effect than the sealing ring and a stable sealing effect, so the floating oil seal is still used in heavy machinery with harsh environment. Thereby what the gap between floating ring and the stationary ring of floating oil seal need be adjusted and embodied is that sealed terminal surface pressure between floating ring and the stationary ring of floating oil seal, if pressure is too little, floating oil seal will unable realization sealed function, if too big floating oil seal of pressure will wear out seriously even generate heat.
In the prior art, after the on-shaft floating oil seal adjusting structure is used for a long time, the sealing effect is poor, and a sealing ring is easy to soften.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing an epaxial floating oil seal adjusts structure to solve the problem that the sealed effect of epaxial floating oil seal adjusts structure after long-time the use is poor, the sealing washer softens easily.
In order to achieve the above purpose, the technical scheme of the utility model is realized like this:
the on-shaft floating oil seal adjusting structure comprises an adjusting nut, a static sealing ring mounting sleeve and a dynamic sealing ring mounting sleeve;
the adjusting nut, the static sealing ring mounting sleeve and the dynamic sealing ring mounting sleeve are sequentially mounted on the shaft;
the static sealing ring mounting sleeve is mounted with the static sealing ring through a first embedded sealing ring, and the dynamic sealing ring mounting sleeve is mounted with the dynamic sealing ring through a second embedded sealing ring 。 The position of the static seal installation sleeve can be adjusted by rotating the adjusting nut, and the gap between the static seal installation sleeve and the movable seal installation sleeve is adjusted to a proper position, so that the adjustment of the pressure value of the floating seal is realized, the floating oil seal can achieve the sealing function, and the floating oil seal cannot be rotated due to too large pressureThe service life is reduced by overheating.
Further, first inlay the sealing ring and inlay the sealing ring with the second and all include external seal ring and sealed inner ring, be equipped with the through-hole that is used for placing sealed inner ring on the external seal ring, the inside accommodation space that is used for holding sealed inner ring that is equipped with of external seal ring, sealed inner ring passes through the through-hole and installs in the external seal ring. The outer sealing ring has a certain residual space, so that the circular hole has a certain residual space, and the sealing ring has certain deformation capacity. Preferably, the material of the outer sealing ring is elastic material, such as elastic rubber, and the material of the inner sealing ring is hard material, such as hard rubber. The sealing ring is inlayed to first inlay sealing ring and second that this device used after long-time the use, and too big deformation does not take place for the hard rubber in the sealing ring is inlayed to first inlay sealing ring and second, consequently first inlay sealing ring and second inlay the sealing ring and can be after long-time the use, and the external seal ring still can realize sealing.
Further, the diameter of the through hole is larger than that of the sealing inner ring.
Further, the diameter ratio of the outer sealing ring to the inner sealing ring is 1:0.3-0.6.
Furthermore, a gap is reserved between the static sealing ring mounting sleeve and the dynamic sealing ring mounting sleeve.
Furthermore, the upper parts of the working surfaces of the static sealing ring and the dynamic sealing ring are sprayed with metal wear-resistant layers. This device is through being equipped with the metal wearing layer, can strengthen the wearability of static sealing ring, moving the sealing ring, and then prolongs the device's life.
Furthermore, the metal wear-resistant layer is formed by spraying wear-resistant metal powder.
Furthermore, the static sealing ring mounting sleeve is slidably mounted on the shaft, a mounting groove is formed in the inner side, close to the shaft, of the static sealing ring, and an O-shaped ring is arranged in the mounting groove of the static sealing ring.
Compared with the prior art, the on-axis floating oil seal adjusting structure has the following advantages:
1. this device adjusts the position of static seal installation cover through rotatory adjusting nut, transfers suitable position with the gap between static seal installation cover and the dynamic seal installation cover to realize the regulation of floating seal's pressure value, make floating seal can reach sealed function and can not lead to the rotatory overheated life that reduces of floating seal because of pressure is too big again.
2. The sealing ring is inlayed to first inlay sealing ring and second that this device used after long-time the use, and the hard rubber in the sealing ring is inlayed to first inlay sealing ring and second does not take place too big deformation, and the difficult emergence of inside sealed inner ring is softened, therefore first inlay sealing ring and second inlay the sealing ring and can be after long-time the use, and the external seal ring still can realize sealedly.
