Description
Technical Field
The utility model relates to a loader transaxle equipment technical field, concretely relates to 6 tons of heavy load type loader transaxle wheel limit oil baffle structure.
Background
The wheel loader in the engineering machinery industry generally has the condition of bad working environment, especially the site environment of working conditions such as coal mine, mine and silt, and impurities such as silt and coal dust enter gear oil and the damage rate of wheel-side gear abrasion to a drive axle hub oil seal is high. The existing loader drive axle hub oil seal structure is generally to assemble a framework oil seal on a hub so as to prevent the leakage of gear oil in an inner cavity of the hub and the entry of impurities on the outer side into the inner cavity of the hub. The outer side of a loader drive axle in the prior art generally adopts a dust cover mode to protect an oil seal, and the inner side oil seal is directly contacted with gear oil. The existing defects are that: along with loader operating time constantly lengthens, the iron powder that wheel limit inner chamber constantly produced and the impurity such as buggy, the ash bed that gets into become silt after mixing with gear oil, silt flows at the wheel hub inner chamber, will enter into the oil blanket lip when silt contacts inboard oil blanket, and the oil blanket lip lasts and coal powder, dust, contact such as silt cause wearing and tearing, treats to lead to the sealed inefficacy of oil blanket after wearing and tearing to a certain extent, finally leads to transaxle oil leak trouble, has reduced transaxle's life.
Disclosure of Invention
The utility model aims at providing a preparation and simple to operate, with low costs, block that the effectual 6 tons of heavy load type loader transaxle wheel limit oil baffle structures of impurity, solve among the prior art because of the wheel limit inner chamber produce behind the impurity get into inboard oil blanket lip and arouse that lip wearing and tearing lead to the problem of the sealed inefficacy oil leak of oil blanket.
In order to achieve the purpose, the wheel side oil baffle plate structure of the 6-ton heavy-load type loader drive axle comprises a wheel hub 1, a support shaft 2, a bearing 3, an oil baffle plate 4, an oil seal 5 and an oil seal seat 6; the bearing 3 is assembled on the hub 1, an outer ring and an inner ring of the bearing 3 are in interference fit with an inner hole of the hub 1 and the support shaft 2 respectively, and the hub 1 rotates around the support shaft 2 through the bearing 3; the oil seal seat 6 is assembled on the support shaft 2, the oil seal 5 is assembled in an inner hole of the hub 1, and a lip of the oil seal 5 is in contact with the oil seal seat 6; the oil baffle 4 is shaped like a circular tray with a mounting round hole in the middle, the oil baffle 4 is arranged between the bearing 3 and the oil seal 5, and the oil baffle 4 is in interference fit with the inner hole of the hub 1 and is sleeved on the oil seal seat 6 through the mounting round hole of the oil baffle 4.
The 6-ton heavy-load loader drive axle wheel-side oil baffle structure with the structure has the following technical characteristics and beneficial effects by additionally arranging the oil baffle at the wheel hub to block impurities from contacting with an inner side oil seal:
1. the part cost is low, and the assembly is simple;
2. the impurity blocking effect is good, and the gear oil can pass through well.
The utility model discloses 6 ton heavy load type loader transaxle wheel limit oil baffle structure has solved and has gone into the problem that leads to the sealed inefficacy oil leak of oil blanket behind inboard oil blanket lip, the lip wearing and tearing because of wheel limit inner chamber produces impurity, has improved product quality greatly, has reduced the maintenance cost.
Drawings
Fig. 1 is the main schematic sectional view of the oil baffle structure at the wheel side of the drive axle of the 6-ton heavy-duty loader.
Reference numerals are as follows: the device comprises a hub 1, a support shaft 2, a bearing 3, an oil baffle 4, an oil seal 5 and an oil seal seat 6. And an oil seal seat 6.
Detailed Description
The structure of the oil baffle at the wheel edge of the drive axle of the 6-ton heavy-duty loader according to the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the wheel-side oil baffle structure of the drive axle of the 6-ton heavy-duty loader of the present invention comprises a wheel hub 1, a support shaft 2, a bearing 3, an oil baffle 4, an oil seal 5 and an oil seal seat 6; the bearing 3 is assembled on the wheel hub 1, the outer ring and the inner ring of the bearing 3 are respectively in interference fit with the inner hole of the wheel hub 1 and the supporting shaft 2, and the wheel hub 1 rotates around the supporting shaft 2 through the bearing 3; the oil seal seat 6 is assembled on the support shaft 2, the oil seal 5 is assembled in an inner hole of the hub 1, and a lip of the oil seal 5 is in contact with the oil seal seat 6; the oil baffle 4 is shaped like a circular tray with a mounting round hole in the middle, the oil baffle 4 is arranged between the bearing 3 and the oil seal 5, and is in interference fit with the inner hole of the hub 1 and sleeved on the oil seal seat 6 through the mounting round hole of the oil baffle 4.
Loader during operation, wheel hub lasts the rotation, along with operating time's extension, the iron powder that the wheel limit inner chamber constantly produced and the buggy that gets into, impurity such as ash bed becomes silt after mixing with the gear oil, silt flows at the wheel hub inner chamber, wheel hub's rotary motion lets silt remain in the inboard of oil baffle 4, be close to one side of bearing promptly, thereby stopped silt and oil blanket contact, more can not get into the oil blanket lip, thereby avoided the wearing and tearing of oil blanket lip to cause the sealed inefficacy of oil blanket and finally lead to transaxle oil leak trouble.
