Abstract
The utility model discloses a wheel edge dust-proof structure of a wheel edge speed reducer of a loader, which comprises a wheel hub, a supporting shaft, a bearing, an oil seal, a dust-proof plate, bolts, polytetrafluoroethylene rectangular rings and an oil seal spacer bush; the bearing is arranged on the hub, the right side of the bearing is provided with an oil seal spacer, and an inner ring and an outer ring of the oil seal are respectively matched with the oil seal spacer and the hub to form a sealing structure; the dustproof plate is arranged on the wheel shell and is fixed on the wheel hub through bolts; the polytetrafluoroethylene rectangular ring is arranged in a rectangular groove of the inner hole of the dust guard. The utility model has the advantages of simple and compact structure, low manufacturing and maintenance cost and reliable use, and solves the problem that the oil seal lip is worn out and oil leakage is caused by the fact that sediment easily enters the oil seal lip when the existing loader works.
Description
Technical Field
The utility model relates to the technical field of loader wheel-side speed reducer assemblies, in particular to a dust-proof structure of a loader wheel-side speed reducer.
Background
The loader is often operated under the abominable operating mode condition that dust, silt are more, and the wheel limit oil blanket oil leak fault rate is higher under this operating mode environment of loader transaxle. The wheel rim structure of the prior art is generally provided with an oil seal, and the outside of the oil seal is not provided with a dustproof structure. The loader wheel edge structure has the following defects: during operation, sediment easily enters into the oil seal lip to cause oil leakage faults caused by abrasion of the oil seal lip, so that the use reliability of the drive axle is reduced, and the after-sale maintenance cost is increased.
Disclosure of Invention
The utility model aims to solve the defects, and provides the wheel edge dust-proof structure of the wheel edge speed reducer of the loader, which has the advantages of simple and compact structure, low manufacturing and maintenance cost and reliable use, and solves the problem that silt easily enters an oil seal lip to cause abrasion of the oil seal lip to cause oil leakage when the existing loader works.
In order to achieve the purpose, the wheel edge dust-proof structure of the wheel edge speed reducer of the loader comprises a wheel hub 1, a supporting shaft 2, a bearing 3, an oil seal 4, a dust-proof plate 5, bolts 6, polytetrafluoroethylene rectangular rings 7 and an oil seal spacer bush 8; the bearing 3 is arranged on the hub 1, the right side of the bearing 3 is provided with an oil seal spacer bush 8, and the inner ring and the outer ring of the oil seal 4 are respectively matched with the oil seal spacer bush 8 and the hub 1 to form a sealing structure; the dustproof plate 5 is arranged on the wheel shell, and the dustproof plate 5 is fixed on the wheel hub 1 through bolts 6; the polytetrafluoroethylene rectangular ring 7 is arranged in a rectangular groove of the inner hole of the dust guard 5.
Above-mentioned loader wheel limit reduction gear wheel limit dust proof structure is through increasing dust guard 5 on the wheel casing, and the dust guard 5 hole is equipped with the dustproof construction of polytetrafluoroethylene rectangle circle 7, has following technical characteristics and beneficial effect:
1. the dustproof structure of the dustproof plate 5 and the polytetrafluoroethylene rectangular ring 7 is additionally arranged on the outer side of the oil seal 4, so that the polytetrafluoroethylene material has good wear resistance, dust and sediment can be effectively prevented from entering the oil seal 4, the service life of the oil seal is prolonged, and the reliability of a drive axle is enhanced;
2. the structure is simple and compact, corresponding parts are easy to process, and the manufacturing and maintenance costs are low.
Drawings
FIG. 1 is a schematic diagram of the main cross-sectional structure of the wheel-side dust prevention structure of the wheel-side speed reducer of the loader.
Reference numerals: hub 1, back shaft 2, bearing 3, oil blanket 4, dust guard 5, bolt 6, polytetrafluoroethylene rectangle circle 7, oil blanket spacer 8.
Detailed Description
The dust-proof structure of the loader wheel-side speed reducer wheel side of the present utility model will be described in further detail with reference to the accompanying drawings and the specific embodiments.
The utility model discloses a dust-proof structure for a wheel edge speed reducer of a loader, which is shown in figure 1, and comprises a wheel hub 1, a supporting shaft 2, a bearing 3, an oil seal 4, a dust-proof plate 5, bolts 6, polytetrafluoroethylene rectangular rings 7 and an oil seal spacer bush 8; the bearing 3 is arranged on the hub 1, the right side of the bearing 3 is provided with an oil seal spacer bush 8, and the inner ring and the outer ring of the oil seal 4 are respectively matched with the oil seal spacer bush 8 and the hub 1 to form a sealing structure; the dustproof plate 5 is arranged on the wheel shell, and the dustproof plate 5 is fixed on the wheel hub 1 through bolts 6; the polytetrafluoroethylene rectangular ring 7 is arranged in a rectangular groove of the inner hole of the dust guard 5.
Above-mentioned loader wheel limit reduction gear wheel limit dust proof structure through increasing the dust guard on the wheel casing, and the dust guard hole is equipped with the rectangular channel, is equipped with polytetrafluoroethylene material's rectangle circle in the rectangular channel, can effectively avoid silt, dust entering oil blanket, improves the life of oil blanket, finally improves the transaxle reliability, increases enterprise income.
