Abstract
The utility model discloses a loader drive axle hub oil seal assembly structure, which comprises a support shaft, a hub, a bearing, a spacer bush, a combined oil seal and a gasket, wherein the support shaft is arranged on the support shaft; the inner ring of the bearing is arranged on the supporting shaft, and the outer ring of the bearing is arranged on the hub; the gasket is assembled on the supporting shaft and is clung to one side end face of the bearing inner ring; the outer circle of the combined oil seal is assembled and fixed on the hub, and the inner hole of the combined oil seal is matched with the supporting shaft to achieve the sealing effect; the spacer bush is assembled on the hub and is positioned between the combined oil seal and the outer ring of the bearing to limit the combined oil seal, and a gap exists between the outer ring of the spacer bush and the hub, so that the spacer bush can be assembled into the hub on the premise of not scratching oil packaging coordination. The utility model has the advantages of simple and compact structure, convenient assembly, good dustproof effect, long service life and low maintenance cost.
Description
Technical Field
The utility model relates to the technical field of loader drive axle hub reduction gear assemblies, in particular to a loader drive axle hub oil seal assembly structure.
Background
The wheel loader in the domestic engineering machinery industry is often in a severe working environment, particularly a loader provided with a wet drive axle, because gravel and broken stone are extremely easy to adhere to a wheel-side oil seal during long-term underground operation, and part of soil is also caused to be flushed to the oil seal during cleaning of the loader, the dustproof quality of the oil seal and the tightness of the assembly position of the oil seal and the oil seal are particularly important. The wheel edge of the drive axle of the loader in the prior art is generally leak-proof by adopting a single oil seal, and the oil seal is limited by combining a retainer ring so as to prevent the leakage of oil in the loader. The defects are: on one hand, the retainer ring is easy to scratch the oil packaging coordination in the assembly process due to the overlarge retainer ring, and the retainer ring needs to be disassembled by a large-sized clamp spring clamp during use and maintenance, so that secondary scratch is easy to occur, and the large-sized clamp spring clamp is less; on the other hand, the single oil seal is poor in dustproof effect, and when the wheel edge rotates, the oil seal is easy to damage due to sand, soil and other sundries, so that the oil seal is invalid, and finally, the oil leakage fault of the drive axle is caused, and the service life of the drive axle is reduced.
Disclosure of Invention
The utility model aims to overcome the defects and provide the loader drive axle hub oil seal assembly structure which has the advantages of simple and compact structure, convenient assembly, good dustproof effect, long service life and low maintenance cost.
In order to achieve the above purpose, the utility model relates to a loader drive axle hub oil seal assembly structure, which comprises a support shaft 1, a hub 2, a bearing 3, a spacer bush 4, a combined oil seal 5 and a gasket 6; the inner ring of the bearing 3 is arranged on the supporting shaft 1, and the outer ring is arranged on the hub 2; the gasket 6 is assembled on the support shaft 1 and is tightly attached to one side end face of the bearing inner ring; the outer circle of the combined oil seal 5 is assembled and fixed on the hub 2, and the inner hole of the combined oil seal 5 is matched with the support shaft 1 to achieve a sealing effect; the spacer bush 4 is assembled on the hub 2 and is positioned between the combined oil seal 5 and the outer ring of the bearing to limit the combined oil seal, and a gap exists between the outer ring of the spacer bush 4 and the hub 2, so that the size of the spacer bush is enough to be installed into the hub on the premise of not scratching oil packaging coordination.
The gap between the outer ring of the spacer bush 4 and the hub 2 is 3 wires.
The combined oil seal 5 can effectively prevent oil leakage, can well prevent oil leakage caused by oil seal failure due to abrasion of particulate matters such as sand, soil and the like, and greatly prolongs the service life and reliability of the drive axle.
The loader drive axle hub oil seal assembly structure with the structure is characterized in that the retainer ring is replaced by the spacer ring to limit the oil seal, and meanwhile, the hub oil seal is changed into a combined oil seal from a single oil seal, so that the loader drive axle hub oil seal assembly structure has the following technical characteristics and beneficial effects:
1. the structure is simple and compact, the assembly is convenient and efficient, the oil packaging coordination is not scratched, and the sealing is ensured;
2. the combined oil seal has good leakage and dust prevention effects, and greatly prolongs the service life and reliability of the drive axle.
The utility model discloses a loader drive axle hub oil seal assembly structure, which solves the problems existing in the prior art: because the dustproof effect of the hub oil seal is poor, the hub oil seal is contacted with pulverized coal, dust, silt and the like for a long time, so that part of particles are continuously worn out after penetrating into the oil seal lip, the oil seal is invalid and leaked, the problem that the oil seal is invalid and leaked because the retainer ring is easy to scratch an oil seal assembly position is solved, the product quality is greatly improved, and the maintenance cost is reduced.
