Abstract
The utility model discloses a dustproof plate structure for a wheel hub oil seal of a drive axle of a 3-ton loader, which comprises a wheel hub, a wheel edge supporting shaft, a bearing, a brake disc bolt, an oil seal, a dustproof plate and an oil seal seat; the brake disc is locked on the hub through a brake disc bolt; the inner ring and the outer ring of the bearing are respectively in interference fit with the wheel edge supporting shaft and the wheel hub; the oil seal seat is assembled on the wheel edge supporting shaft, the outer circle of the oil seal is assembled and fixed on the wheel hub, and the inner hole of the oil seal is matched with the oil seal seat to achieve a sealing effect; the dustproof plate is assembled on the wheel edge supporting shaft and is tightly pressed through the oil seal seat, the outer circle of the dustproof plate is coaxial with the wheel hub, and the gap between the dustproof plate and the wheel hub is 0.8-1.2mm. The utility model discloses simple structure is compact, dustproof effectual, make and use cost low, has solved among the prior art wheel hub oil blanket and has contacted such as buggy, dust, silt for a long time and the wearing and tearing lip leads to the problem of the sealed inefficacy oil leak of oil blanket after permeating the oil blanket lip.
Description
Technical Field
The utility model relates to an engineering machine tool trade 3 ton loader transaxle wheel reduction gear assembly technical field, concretely relates to 3 ton loader transaxle wheel hub oil blanket dust guard structure.
Background
Wheel loaders in the engineering machinery industry often work under severe environment conditions, such as working conditions of coal mines, silt and the like, and the damage rate of the wheel hub oil seal of the drive axle caused by the working environments is high. The existing loader drive axle hub oil seal structure is generally to assemble a framework oil seal on a hub, and the oil seal is exposed in the air for a long time, so that the dustproof effect on the hub oil seal is particularly important. Loader transaxle generally adopts the mode protection oil blanket of wheel limit supporting axle welding dust cover among the prior art, this oil blanket protection architecture can block external sand grain, the rubble gets into and damages the oil blanket, but because the welding dust cover technology is complicated and yielding, dust cover and wheel hub oil blanket disalignment phenomenon appear easily, cause the dustproof effect of dust cover not good, lead to the oil blanket long-term with buggy, dust, contact such as silt, some granule infiltrates oil blanket lip department constantly wearing and tearing lip, cause the sealed trouble that loses efficacy and finally appear the transaxle and leak oil, transaxle life has been reduced.
Disclosure of Invention
The utility model aims at providing a simple structure is compact, dustproof effectual, make and 3 ton loader transaxle wheel hub oil blanket dust guard structure with low in use cost, solve among the prior art wheel hub oil blanket long-term and contact such as buggy, dust, silt and the problem that the oil blanket lip back wearing and tearing lip leads to the sealed oil leak that became invalid of oil blanket.
In order to achieve the purpose, the 3-ton loader drive axle hub oil seal dustproof plate structure comprises a hub 1, a wheel edge supporting shaft 2, a bearing 3, a brake disc 4, a brake disc bolt 5, an oil seal 6, a dustproof plate 7 and an oil seal seat 8; the brake disc 4 is locked on the hub 1 through a brake disc bolt 5; the inner ring and the outer ring of the bearing 3 are respectively in interference fit with the wheel edge supporting shaft 2 and the wheel hub 1; the oil seal seat 8 is assembled on the wheel edge supporting shaft 2, the outer circle of the oil seal 6 is assembled and fixed on the wheel hub 1, and the inner hole of the oil seal 6 is matched with the oil seal seat 8 to achieve a sealing effect; the dustproof plate 7 is assembled on the wheel edge supporting shaft 2 and is tightly pressed through the oil seal seat 8, the outer circle of the dustproof plate 7 is coaxial with the wheel hub 1, and the gap between the outer circle of the dustproof plate and the wheel hub 1 is 0.8-1.2mm.
Above-mentioned 3 ton loader transaxle wheel hub oil blanket dust guard structure has following technical characterstic and beneficial effect through increasing the dust guard of assembly on the round limit back shaft:
1. the structure is simple and compact, and the assembly is convenient;
2. the dust guard is high in coaxiality after being assembled with the oil seal and the wheel edge supporting shaft, deformation cannot occur, the gap between the dust guard and the wheel edge is small, and the dust-proof effect is obviously superior to that of a welded dust cover structure in the prior art.
The utility model discloses 3 ton loader transaxle wheel hub oil blanket dust guard structure has solved among the prior art because the dustproof effect of wheel hub oil blanket is not good, the wheel hub oil blanket for a long time with contact such as buggy, dust, silt, partial granule infiltration oil blanket lip back constantly wearing and tearing lip lead to the problem of the sealed oil leak that became invalid of oil blanket, has improved product quality greatly, has prolonged transaxle life.
Drawings
Fig. 1 is the utility model discloses 3 ton loader transaxle wheel hub oil blanket dust guard structure owner is cut out the schematic diagram.
Reference numerals: the wheel comprises a hub 1, a wheel edge supporting shaft 2, a bearing 3, a brake disc 4, a brake disc bolt 5, an oil seal 6, a dust guard 7 and an oil seal seat 8.
Detailed Description
The following describes the dustproof plate structure of the wheel hub oil seal of the drive axle of the 3 ton loader in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the wheel hub oil seal dust-proof plate structure of the drive axle of the 3-ton loader of the present invention comprises a wheel hub 1, a wheel-side supporting shaft 2, a bearing 3, a brake disc 4, a brake disc bolt 5, an oil seal 6, a dust-proof plate 7 and an oil seal seat 8; the brake disc 4 is locked on the hub 1 through a brake disc bolt 5; the inner ring and the outer ring of the bearing 3 are respectively in interference fit with the wheel edge supporting shaft 2 and the wheel hub 1; the oil seal seat 8 is assembled on the wheel edge supporting shaft 2, the outer circle of the oil seal 6 is assembled and fixed on the wheel hub 1, and the inner hole of the oil seal 6 is matched with the oil seal seat 8 to achieve a sealing effect; the dustproof plate 7 is assembled on the wheel edge supporting shaft 2 and is tightly pressed through the oil seal seat 8, the outer circle of the dustproof plate 7 is coaxial with the wheel hub 1, and the gap between the outer circle of the dustproof plate 7 and the wheel hub 1 is 0.8-1.2mm, so that the dustproof effect is ensured.
The utility model discloses 3 ton loader transaxle wheel hub oil blanket dust guard structure is through increasing the assembly dust guard, the axiality of dust guard and wheel hub has been improved, the clearance that makes dust guard and wheel limit is very little, avoided the oil blanket long-term and buggy, the dust, contact such as silt, play better dustproof effect, effectively block rate part granule infiltration oil blanket lip back constantly wearing and tearing the lip and lead to the problem of the sealed inefficacy oil leak of oil blanket, greatly reduced transaxle wheel hub oil blanket oil leak trouble, the life and the reliability of transaxle have been improved.
