The utility model provides an among the prior art loader transaxle wheel hub oil blanket wearing and tearing wheel limit back shaft make the back shaft seal inefficacy, cause the problem that the axle housing assembly need be changed in the wheel reduction gear oil blanket oil leak.
Description
Technical Field
The utility model relates to a loader transaxle wheel reduction gear seal structure, concretely relates to loader wheel reduction gear oil blanket axle sleeve structure.
Background
At present, the working environment of a wheel loader in the domestic engineering machinery industry is severe, and particularly the damage rate of the hub oil seal of a drive axle to the working condition field environment of coal mines, silt and the like is high. In the prior art, an oil seal is generally assembled on a hub by a loader drive axle hub oil seal structure, and a lip of the oil seal tightly holds a wheel-side support shaft for sealing. During actual operation, because of the oil blanket for a long time with the impurity contact such as buggy, dust, silt, partly granule infiltration oil blanket lip department, arouse impurity friction such as wheel limit back shaft and buggy, dust, silt and produce the mill mark, continue to use then to lead to grinding out the pit, and finally arouse that the oil blanket lip is embraced the power not enough, sealed inefficacy leads to drive axle wheel limit reduction gear assembly oil leak trouble, because wheel limit back shaft and axle housing welding together, need change the axle housing assembly during the maintenance, cause the problem that maintenance cost is high.
Disclosure of Invention
The utility model aims at overcoming above-mentioned defect, provide a structure and simple, the preparation of assembly and the low loader wheel reduction oil blanket axle sleeve structure of maintenance cost to solve among the prior art loader transaxle wheel hub oil blanket wearing and tearing wheel limit back shaft and make the back shaft seal inefficacy, cause the problem that wheel reduction oil blanket oil leak need change the axle housing assembly.
In order to realize the purpose, the oil seal shaft sleeve structure of the wheel side speed reducer of the loader comprises a wheel hub, a bearing, a wheel side supporting shaft, an oil baffle plate, an oil seal and an oil seal shaft sleeve; the outer ring of the bearing is matched with the wheel hub, and the inner ring of the bearing is matched with the wheel rim support shaft; the oil baffle plate, the oil seal and the oil seal shaft sleeve are all arranged in the hub; the oil seal shaft sleeve is sleeved on the wheel edge support shaft, the left end of the oil seal shaft sleeve is tightly attached to the inner ring of the bearing, and the right end of the oil seal shaft sleeve is limited and fixed through a step arranged on the wheel edge support shaft; the oil baffle is positioned on the right side of the bearing, two oil seals are arranged behind the oil baffle, and the oil baffle and the two oil seals are sleeved on the oil seal shaft sleeve, so that the oil baffle, the oil seals and the oil seal shaft sleeve can generate a sealing effect on the bearing.
The loader wheel side reduction gear oil blanket axle sleeve structure of above-mentioned structure has following technical characterstic and beneficial effect through increasing the assembly oil blanket axle sleeve on the wheel side back shaft:
1. after the oil seal shaft sleeve is abraded, only the oil seal shaft sleeve needs to be replaced, the axle housing assembly does not need to be replaced, and the maintenance cost is low.
2. Simple structure and convenient assembly.
The utility model provides an among the prior art because the wheel hub oil blanket contacts with impurity such as buggy, dust, silt for a long time, thereby lead to the problem that the sealed inefficacy oil leak of oil blanket must be changed axle housing assembly behind the regrinding wheel limit back shaft, greatly reduced the maintenance cost.

Reference numerals: the wheel hub 1, the bearing 2, the wheel limit back shaft 3, keep off the oil board 4, the oil blanket 5, the oil blanket axle sleeve 6.
Detailed Description
The following describes the oil seal shaft sleeve structure of the wheel side reducer of the loader in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the oil seal shaft sleeve structure of the wheel side speed reducer of the loader of the present invention includes a wheel hub 1, a bearing 2, a wheel side support shaft 3, an oil baffle 4, an oil seal 5 and an oil seal shaft sleeve 6; the outer ring of the bearing 2 is matched with the hub 1, and the inner ring is matched with the hub supporting shaft 3; the oil baffle 4, the oil seal 5 and the oil seal shaft sleeve 6 are all arranged in the hub 1; the oil seal shaft sleeve 6 is sleeved on the wheel edge support shaft 3, the left end of the oil seal shaft sleeve is tightly attached to the inner ring of the bearing 2, and the right end of the oil seal shaft sleeve is limited and fixed through a step arranged on the wheel edge support shaft 3; the oil baffle 4 is positioned on the right side of the bearing 2, two oil seals 5 are arranged behind the oil baffle 4, and the oil baffle 4 and the two oil seals 5 are both sleeved on an oil seal shaft sleeve 6, so that the oil baffle 4, the oil seals 5 and the oil seal shaft sleeve 6 generate a sealing effect on the bearing 2.
During assembly, firstly, the oil seal shaft sleeve 6 is sleeved into the wheel edge support shaft 3, and the bearing 2 is assembled with the wheel hub 1; then an oil baffle 4 and two oil seals 5 are installed; and finally, the bearing 2 is supported on the wheel-side supporting shaft 3, so that the oil seal 5 and the oil seal shaft sleeve 6 are ensured to generate a sealing effect.
When the loader is in operation, because of the long-term contact with impurity such as oil blanket 5 and buggy, dust, silt, some granule will permeate oil blanket lip department and make the buggy, dust, impurity such as silt produces the mill mark after rubbing with oil blanket axle sleeve 6, continue to use and will lead to oil blanket axle sleeve 6 to grind out the pit, make oil blanket axle sleeve 6 inefficacy lead to the oil leak, this moment only need change oil blanket axle sleeve 6 can, and need not change axle housing assembly seam spare, the maintenance cost of renewal part has been reduced greatly, the life and the reliability of transaxle have been improved.
The utility model discloses the fine solution of loader wheel limit reduction gear oil blanket axle sleeve structure among the prior art because wheel limit back shaft wearing and tearing need change the axle housing assembly after, causes the high problem of maintenance cost.
