Abstract

A drive axle wheel side dustproof structure comprises a single-lip frame oil seal, a double-lip frame oil seal, an oil seal base, a dustproof oil seal, a dustproof plate and a supporting shaft. The oil seal base is arranged on the supporting shaft. The single-lip frame oil seal, the double-lip frame oil seal and the dustproof oil seal are arrayed on the oil seal base in sequence. A gap is formed between the supporting shaft and the dustproof plate connected at the end portion of a hub. Due to the drive axle wheel side dustproof structure, the dustproof oil seal and the dustproof plate are added, dust and silt are prevented from entering the single-lip frame oil seal and the double-lip frame oil seal to abrade lip openings, a better dustproof effect can be achieved, the probability of failure oil leakage caused by dust particle abrasion of the single-lip frame oil seal and the double-lip frame oil seal on the wheel side is lowered, the service life of a drive axle is prolonged, and the reliability of the drive axle is improved.

Description

Drive axle wheel edge dustproof construction
Technical field
The utility model relates to a kind of wheel limit dustproof construction of Driving Axle of Wheel Loader.
Background technique
The construction site amount of dust such as wheel loader work under bad environment, especially colliery, mine, silt, quantity of sand and mud are large, and drive axle wheel edge is dustproof particularly important.Conventional main dust prevention is: drive axle wheel edge is arranged two outside framework oil seals successively, inner ring oil sealing is grease proofing, outer ring oil sealing is dustproof, outer ring oil sealing contacts with dust, silt for a long time, part particle penetrates into the continuous grinding lip in oil seal lip place, cause outer ring oil sealing, inner ring oil sealing sealing to lose efficacy, occur oil leakage phenomenon, greatly reduce ransaxle working life.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-gray good sealing effect, can reduces oil leakage fault, improves the working life of ransaxle and the Driving Axle of Wheel Loader of reliability wheel limit dustproof construction.
The purpose of this utility model is achieved in that and comprises single lip outside framework oil seal, Double-lip framework oil sealing, oil sealing base, anti-dust seal, dust guard, back shaft, oil sealing base is arranged on back shaft, on oil sealing base, order is arranged with single lip outside framework oil seal, Double-lip framework oil sealing and anti-dust seal, gapped between the dust guard that hub end connects and back shaft.
Because the utility model has adopted said structure, an anti-dust seal and dust guard have been increased, blocks dust and silt enter wearing and tearing lip in single lip outside framework oil seal and Double-lip framework oil sealing, can play better dust-proof effect, reduce the single lip outside framework oil seal in wheel limit and Double-lip framework oil sealing because of the probability of dust granule wearing and tearing inefficacy leakage of oil, improved working life and the reliability of ransaxle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 wheel hub, 2 bolts, 3 Double-lip framework oil sealings, 4 oil sealing bases, 5 anti-dust seals, 6 dust guards, 7 back shafts, 8 single lip outside framework oil seals in figure.
Embodiment
Embodiment: as shown in Figure 1, this dustproof construction, comprise single lip outside framework oil seal 8, Double-lip framework oil sealing 3, oil sealing base 4, anti-dust seal 5, dust guard 6, back shaft 7, described single lip outside framework oil seal 9, Double-lip framework oil sealing 3 is closely placed continuously with anti-dust seal 5, single lip outside framework oil seal 8, the internal diameter of Double-lip framework oil sealing 3 coordinates with oil sealing base 4 external diameters, single lip outside framework oil seal 8, the external diameter of Double-lip framework oil sealing 3 and anti-dust seal 5 coordinates with wheel hub 1 end endoporus, dust guard 6 is connected with wheel hub 1 end by bolt 2, overall structure is simple, be easy to realize, Spielpassung between dust guard 6 and back shaft 7, can completely cut off most of dust, only have few part dust to cross dust guard 6, but be blocked in outside anti-dust seal 5, so single lip outside framework oil seal 8 and Double-lip framework oil sealing 3 are just relatively being worked in clean environment.
The utility model can more effectively play dust-proof effect, single lip outside framework oil seal 8 of taking turns limit is worked in relative clean environment with Double-lip framework oil sealing 3, can greatly improve the working life of single lip outside framework oil seal 8 and Double-lip framework oil sealing 3, reduce the oil leakage fault of single lip outside framework oil seal 8 and Double-lip framework oil sealing 3, improve working life and the reliability of ransaxle.

Claims (1)

1. a drive axle wheel edge dustproof construction, comprise single lip outside framework oil seal, Double-lip framework oil sealing, oil sealing base, anti-dust seal, dust guard, back shaft, it is characterized in that: oil sealing base is arranged on back shaft, on oil sealing base, order is arranged with single lip outside framework oil seal, Double-lip framework oil sealing and anti-dust seal, gapped between the dust guard that hub end connects and back shaft.
