Abstract
The utility model relates to a sealing element, in particular to an oil seal applicable to a splash lubrication mode. The oil seal comprises an oil seal body. The oil seal body comprises a skeleton, a spring and a sealing lip. The sealing lip comprises a main sealing lip. The spring is located on the annular outer side of the main sealing lip. An annular side wall of the side, close to the spring, of the oil seal is a catch spring wall. The oil seal further comprises an oil collecting disc. The oil collecting disc comprises a metal supporting ring and stopping ribs arranged on the end face of the metal supporting ring. The metal supporting ring is perpendicular to the axial direction of a rotating shaft. An inner hole is formed in the center of the metal supporting ring. The diameter dimension of the inner hole of the metal supporting ring is larger than that of the catch spring wall of the oil seal body. The stopping ribs are distributed on the end face of the metal supporting ring in an array mode in the circumferential direction. The oil collecting disc is in clearance fit with the skeleton of the oil seal body. The end face of the metal supporting ring is located at the position which extends out of the main sealing lip in the axial direction. Enough lubricating oil exists at the main sealing lip so that a complete oil film can be ensured between the main sealing lip and the axial face, the lip is not easily abraded, and the long-term sealing effect of the oil seal is ensured.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of oil sealing that is applicable to splash lubrication pattern.
Background technique
Oil sealing is mainly used in sealing between the parts that relatively rotate, and prevents that the lubricant oil of machinery inside from leaking.Conventional oil sealing is made up of support ring, rubber body and spring, and its medi-spring forms primary seal lip with the rubber body with given shape, realizes the sealing to axle.After oil sealing assembling, the elastic packing lip position of being made up of rubber and running shaft interference fit, produce certain enclasping force to axle, can make oil sealing in use realize the sealing to axle by enclasping force.Although enclasping force is the necessary condition that guarantees sealing, due to frictional heat, easily to cause rubber mill to undermine aging, and therefore enclasping force also can produce harmful effect to oil seal lip.In order to guarantee the reliable sealing in long-term using process, between primary seal lip port part and axial plane, must there is complete oil film to exist, form pump and inhale effect, to realize sealing, and reduce the wearing and tearing of lip, primary seal lip port part must keep good lubricating status.But under splash lubrication pattern, the lubricant oil of primary seal lip port part relies on splash for obtaining completely.And this kind of lubricating system is difficult to guarantee that enough lubricant oil arrives primary seal lip, because only have the lubricant oil that is just in time splashed to primary seal lip port part to play lubrication to it, and most splash lubrication oil can not be splashed to primary seal lip port part just in real work, therefore cannot realize lubricating primary seal lip.
Model utility content
The purpose of this utility model has been to propose a kind of oil sealing that is applicable to splash lubrication pattern, this oil sealing can make primary seal lip mouth place have enough lubricant oil to guarantee there is complete oil film between itself and axial plane, lip is not easy to wear, has guaranteed the long term seal effect of oil sealing.
The utility model is to adopt following technological scheme to realize: a kind of oil sealing that is applicable to splash lubrication pattern, comprise oil sealing body, oil sealing body comprises skeleton, spring and sealing lip, described sealing lip comprises primary seal lip, spring is positioned at the annular outboard of primary seal lip, oil sealing is catch spring wall near the annular sidewall of spring one side, wherein, this oil sealing also comprises oil-collecting disk, oil-collecting disk comprises metal supporting rings and is arranged in the barrier rib of metal supporting rings end face, metal supporting rings is perpendicular to the axial setting of running shaft, the center of metal supporting rings is provided with endoporus, its diameter of bore size is greater than the diameter dimension of oil sealing body catch spring wall, barrier rib array distribution along the circumferential direction on metal supporting rings end face, between the skeleton of oil-collecting disk and oil sealing body, be interference fit, the end face area of metal supporting rings is axially being stretched out the position of primary seal lip.
In the utility model, described barrier rib is along the circumferential direction uniform array distribution on metal supporting rings end face.
Described barrier rib is combined into one by vulcanization and metal supporting rings, and the quantity of barrier rib is generally more than 12, and the cross section of barrier rib is rectangle.
The beneficial effects of the utility model are: by oil-collecting disk is set, can guarantee that the lubricant oil that the barrier rib of running shaft top is collected can drip near on the axial plane of primary seal lip port part, also can not make the lubricant oil that should be splashed to primary seal lip port part be stopped simultaneously, make primary seal lip can obtain enough lubricant oil and guarantee there is complete oil film between itself and axial plane, inhale effect to realize pump, avoid primary seal lip by Fast Wearing, guarantee the long term seal effect of oil sealing.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 2, Figure 3 and Figure 4, this oil sealing comprises oil sealing body 2 and oil-collecting disk 3, and oil sealing body 2 comprises skeleton, spring and sealing lip, and described sealing lip comprises primary seal lip 21, spring is positioned at the annular outboard of primary seal lip 21, and spring provides enclasping force for primary seal lip 21.Oil sealing is catch spring wall 211 near the annular sidewall of spring one side.Described oil-collecting disk 3 comprises metal supporting rings 32 and is arranged in the barrier rib 31 of metal supporting rings end face, metal supporting rings 32 is perpendicular to the axial setting of running shaft 1, metal supporting rings 32 center is provided with endoporus, its diameter of bore size is slightly larger than the diameter dimension of oil sealing body catch spring wall 211, so that primary seal lip 21 positions axially can all exposed, avoid the lubricant oil that should be splashed to primary seal lip 21 positions to be stopped.Barrier rib 31 is along the circumferential direction uniform array distribution on metal supporting rings 32 end faces, and barrier rib 31 is combined into one by vulcanization and metal supporting rings 32, and the quantity of barrier rib 31 is generally more than 12, and the cross section of barrier rib 31 can be rectangle.Between the skeleton of oil-collecting disk 3 and oil sealing body, be interference assembling, thereby oil-collecting disk 3 and oil sealing body 2 are combined.The end face area of metal supporting rings 32 is in the position of axially stretching out primary seal lip 21 simultaneously, to guarantee that the lubricant oil that the barrier rib 31 of running shaft 1 top is collected can drip on the axial plane near primary seal lip 21 positions, thereby realize lubricating primary seal lip 21.
