Abstract
The utility model discloses a wheel-side oil seal fixing structure of a loader drive axle, which comprises a wheel hub (1), an oil seal (2), a support shaft (5), a bearing (6), an oil seal seat (7) and an oil baffle plate (8), wherein all the parts are assembled and then are installed on the support shaft (5); an L-shaped bulge (7-1) is arranged at the outer end excircle of the oil seal seat (7) to protect the oil seal (2); the oil baffle plate (8) is arranged between the bearing (6) and the oil seal seat (7) to separate oil in the inner cavity of the hub (1) from the oil seal (2) and prevent the axial movement of the oil seal (2). The utility model has simple structure, low manufacturing and maintenance cost and reliable operation, and solves the problem of oil leakage caused by oil seal movement due to insufficient fixed protection of the oil seal in the prior art.
Description
Technical Field
The utility model relates to the technical field of loader drive axle assemblies, in particular to a wheel side oil seal fixing structure of a loader drive axle.
Background
The structure of the oil seal of the wheel-side reducer assembly of the existing loader drive axle is generally the structure shown in figure 1, and comprises a wheel hub 1, an oil seal 2, a fixing bolt 3, a dust cover 4, a support shaft 5, a bearing 6 and an oil seal seat 7, wherein all the parts are installed on the support shaft 5 after being assembled. In the use process, because the fixed protection to the oil blanket 2 is not enough, can cause the fault phenomenon of oil leak because of the oil blanket drunkenness sometimes.
Disclosure of Invention
The utility model aims to overcome the defects and provide the wheel-side oil seal fixing structure of the loader drive axle, which has the advantages of simple structure, low manufacturing and maintenance cost and reliable operation, so as to solve the problem of oil leakage caused by oil seal movement due to insufficient fixing protection of the oil seal in the prior art.
In order to realize the purpose, the wheel-side oil seal fixing structure of the loader drive axle comprises a wheel hub 1, an oil seal 2, a support shaft 5, a bearing 6, an oil seal seat 7 and an oil baffle plate 8, wherein all the parts are installed on the support shaft 5 after being assembled; an L-shaped bulge 7-1 is arranged at the outer end excircle of the oil seal seat 7 to protect the oil seal 2; the oil baffle plate 8 is arranged between the bearing 6 and the oil seal seat 7 so as to block oil in the inner cavity of the hub 1 from the oil seal 2 and prevent the oil seal 2 from axially moving.
The loader transaxle wheel limit oil blanket fixed knot of above-mentioned structure increases fixing device to the oil blanket through cancellation dust cover and dust cover fixing bolt, has following technical characterstic and beneficial effect:
1. the L-shaped bulge 7-1 is additionally arranged on the outer end excircle of the oil seal seat 7, so that the oil seal 2 can be prevented from moving towards the excircle direction in the working process, and meanwhile, the L-shaped bulge 7-1 also plays a dustproof role, so that the situation that the oil seal fails too early due to the direct contact of external sundries and the oil seal 7 can be effectively prevented;
2. after the L-shaped bulge 7-1 is added on the oil seal seat 7, the installation of the dust cover 4 can be cancelled, and the operation efficiency is improved;
3. through increase oil baffle 8 between bearing 6 and oil seal seat 7, not only play certain separation effect to 1 inner chamber oil of wheel hub and oil blanket 2, oil baffle 8 still can effectively prevent the too much drunkenness of 2 groove bearings 6 directions of oil blanket.
Drawings
FIG. 1 is a schematic view of a main sectional structure of an oil seal of a wheel-side reducer assembly of a drive axle of a loader in the prior art.
FIG. 2 is a main sectional structural view of the wheel-side oil seal fixing structure of the loader drive axle of the present invention.
Fig. 3 is a schematic main sectional structure view of the oil seal seat in fig. 2.
Reference numerals: the device comprises a hub 1, an oil seal 2, a fixing bolt 3, a dust cover 4, a support shaft 5, a bearing 6, an oil seal seat 7, an L-shaped bulge 7-1 and an oil baffle plate 8.
Detailed Description
The following describes the wheel-side oil seal fixing structure of the drive axle of the loader in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2-3, the wheel-side oil seal fixing structure of the loader drive axle of the utility model comprises a wheel hub 1, an oil seal 2, a support shaft 5, a bearing 6, an oil seal seat 7 and an oil baffle plate 8, wherein all the components are installed on the support shaft 5 after being assembled; an L-shaped bulge 7-1 is arranged at the outer end excircle of the oil seal seat 7 to protect the oil seal 2; the oil baffle plate 8 is arranged between the bearing 6 and the oil seal seat 7 so as to block oil in the inner cavity of the hub 1 from the oil seal 2 and prevent the oil seal 2 from axially moving.
According to the wheel-side oil seal fixing structure of the loader drive axle, a dust cover 4 and a dust cover fixing bolt 3 in the prior art are omitted, the oil seal 2 is arranged between the wheel hub 1 and the oil seal seat 7, the L-shaped bulge 7-1 is additionally arranged at the outer end, close to the outer circle, of the oil seal seat 7, and the oil baffle plate 8 is additionally arranged between the bearing 6 and the oil seal seat 7; meanwhile, the L-shaped bulge 7-1 has a dustproof function, so that the phenomenon that the oil seal 2 is prematurely failed due to the fact that external sand and stone and the like are in contact with the oil seal 2 in the working process can be effectively avoided.
