Abstract
The utility model discloses a loader wet-type bridge wheel edge structure, which comprises a support shaft 1 and a wheel hub 4, wherein the wheel hub 4 is arranged and supported on the support shaft 1 through a wheel edge inner bearing 6 and a wheel edge outer bearing 5; an oil seal 2 and a retainer ring 3 are arranged between the supporting shaft 1 and the hub 4 from left to right; a spacer bush 7 is arranged between the supporting shaft 1 and the wheel edge inner bearing 6; the left end of the hub 4 is provided with a hub dustproof boss 9, the support shaft 1 is provided with a support shaft dustproof groove 8 matched with the hub dustproof boss 9, and the hub dustproof boss 9 is embedded into the support shaft dustproof groove 8 to form a labyrinth dustproof space so as to prevent dust foreign matters from entering the oil seal lip position to cause oil leakage fault in the working process; the specification and model of the wheel edge inner bearing 6 adopt 32026, so that the bearing capacity is improved. The utility model discloses dustproof effectual, bearing capacity is strong, long service life, cost of maintenance are low.
Description
Technical Field
The utility model relates to a loader transaxle wheel reduction gear assembly technical field, concretely relates to loader wet-type axle wheel limit structure.
Background
The drive axle of the loader is gradually developed towards a wet axle, a dustproof structure is not arranged on the wheel edge structure of the wet axle of the loader in the prior art, the wheel edge bearing model is small, and 32024 is generally adopted. The wet-type bridge wheel edge structure of the loader has the following defects: firstly, the wet-type bridge wheel edge structure of the loader has no dustproof structure, and foreign matters such as dust and the like can enter the lip position of the oil seal in the actual use process, so that the oil seal is leaked finally; and 32024 is adopted as the wet type axle wheel edge inner bearing of the loader, the bearing capacity is poor, and the bearing failure rate under heavy load working conditions is high.
Disclosure of Invention
The utility model aims at overcoming above-mentioned defect, providing a loader wet-type axle wheel limit structure that dustproof effectual, bearing capacity is strong, long service life, cost of maintenance are low.
In order to achieve the purpose, the wet-type bridge wheel edge structure of the loader comprises a supporting shaft 1 and a wheel hub 4, wherein the wheel hub 4 is arranged and supported on the supporting shaft 1 through a wheel edge inner bearing 6 and a wheel edge outer bearing 5; an oil seal 2 and a retainer ring 3 are arranged between the supporting shaft 1 and the hub 4 from left to right; a spacer bush 7 is arranged between the supporting shaft 1 and the wheel edge inner bearing 6; the left end of the hub 4 is provided with a hub dustproof boss 9, the support shaft 1 is provided with a support shaft dustproof groove 8 matched with the hub dustproof boss 9, and the hub dustproof boss 9 is embedded into the support shaft dustproof groove 8 to form a labyrinth dustproof space so as to prevent dust foreign matters from entering the oil seal lip position to cause oil leakage fault in the working process; the specification and model of the wheel edge inner bearing 6 adopt 32026, so that the bearing capacity is improved.
The loader wet-type bridge wheel edge structure with the structure has the following technical characteristics and beneficial effects:
firstly, the wet type bridge wheel edge structure of the loader is provided with a labyrinth type dustproof structure, so that foreign matters such as dust and the like are prevented from entering the lip position of an oil seal in the using process, and the failure rate is low;
secondly, by enlarging the wheel edge inner bearing and adopting 32026, the bearing capacity is good, the heavy load working condition is adapted, the failure rate is low, and the after-sale maintenance cost is finally reduced.
The utility model discloses loader wet-type axle wheel limit structure is through setting up wheel limit dustproof construction and wheel limit bearing and reselecting the type, has prevented that dust foreign matter from getting into the oil blanket lip position in the course of the work and causing the oil leak trouble, has increaseed bearing capacity, adaptable heavy load operating mode, and the fault rate is low, finally improves the transaxle reliability, and greatly reduced cost of maintenance is low.
