Technical Field
The utility model relates to the technical field of loader drive axle assemblies, in particular to a 3-ton loader drive axle wheel spacer sleeve structure.
Background
The wheel loader in the engineering machinery industry has complex and severe working conditions and frequent continuous operation. The existing drive axle of a loader generally adopts a structure that a wheel-side sun gear end face is in direct contact with a wheel-side support shaft end face, a sun gear rotates and a wheel-side support shaft is fixed during operation, so that relative friction is generated, the hardness of the wheel-side support shaft end face is lower than that of the end face of the sun gear, after the loader works for a period of time, the end face of the support shaft with lower hardness is abraded, iron powder is ground out, the end face of the support shaft is caused to sink after continuous work, the left and right movement amount of the sun gear is increased, the effective contact tooth width of the sun gear and a planet gear is changed, so that a meshing mark is changed, the stress of the sun gear is unbalanced, the gear biting and tooth hitting faults of the sun gear are caused, and then the teeth hitting and damage faults of an internal gear of a wheel-side speed reducer are caused, the drive axle cannot normally run, and finally the loader cannot normally work.
Disclosure of Invention
The utility model aims to overcome the defects and provides a wheel side spacer sleeve structure of a 3-ton loader drive axle, which has the advantages of simple and compact structure, low manufacturing and maintenance cost and long service life, so as to solve the problem that the wheel side of the drive axle is damaged due to the fact that the end surface of a wheel side support shaft is abraded due to the fact that a sun wheel is directly contacted with the end surface of the wheel side support shaft, the shifting amount of the sun wheel is increased, gear meshing is influenced, and the gear meshing and tooth beating faults of the sun wheel are caused in the prior art.
In order to achieve the purpose, the wheel-side spacer structure of the drive axle of the 3-ton loader comprises a half shaft 1, a retainer ring 2, a sun gear 3, a spacer 4, screws 5, round nuts 6, an inner gear ring 7, a bearing 8 and a wheel-side support shaft 9, wherein the bearing 8 is assembled on the wheel-side support shaft 9, the inner gear ring 7 is sleeved on the wheel-side support shaft 9 and is flatly attached to the end surface of the bearing, the round nuts 6 are locked on the wheel-side support shaft 9 and simultaneously lock the inner gear ring 7, the round nuts 6 are locked on the inner gear ring 7 by the two screws 5 to prevent the inner gear ring 7 from moving, the sun gear 3 is assembled on the half shaft 1, and the outer end surface of the sun gear 3 is axially limited by the retainer ring 2; the spacer 4 is assembled in an inner hole at the end part of the wheel edge supporting shaft 9, so that the inner end surface of the sun gear 3 is flush with the end surface of the spacer 4, and the hardness of the inner end surface of the sun gear 3 is equivalent to that of the spacer 4, thereby avoiding abrasion caused by direct contact of the sun gear 3 and the end surface of the wheel edge supporting shaft 9.
The 3-ton loader drive axle wheel side spacer sleeve structure with the structure has the following technical characteristics and beneficial effects that the spacer sleeve is additionally arranged at the end part of the wheel side supporting shaft in contact with the end surface of the sun wheel:
1. the processing and the assembly are simple;
2. the hardness of the spacer bush is equivalent to that of the sun gear, abrasion is not generated any more, the condition that the gear meshing is influenced by increasing the shifting amount of the sun gear is avoided, and the service life of the device is obviously prolonged.
The wheel side spacer sleeve structure of the drive axle of the 3-ton loader solves the problems that the end surface of the wheel side support shaft is abraded due to the direct contact between the sun gear and the end surface of the wheel side support shaft and the too large hardness difference, the shifting amount of the sun gear is increased, the meshing of gears is influenced, the tooth biting and tooth beating faults of the sun gear are caused, and the product quality is greatly improved and the service life is prolonged.

Detailed Description
The wheel spacer sleeve structure of the drive axle of the 3-ton loader is further described in detail by combining the attached drawings and specific embodiments.
As shown in fig. 1, the wheel-side spacer structure of the drive axle of the 3-ton loader comprises a half shaft 1, a retainer ring 2, a sun gear 3, a spacer 4, screws 5, round nuts 6, an inner gear ring 7, a bearing 8 and a wheel-side support shaft 9, wherein the bearing 8 is assembled on the wheel-side support shaft 9, the inner gear ring 7 is sleeved on the wheel-side support shaft 9 and is flush with the end face of the bearing, the round nuts 6 are locked on the wheel-side support shaft 9 and simultaneously lock the inner gear ring 7, and the round nuts 6 are locked on the inner gear ring 7 by the two screws 5 so that the inner gear ring 7 does not move; the spacer bush 4 is assembled in an inner hole at the end part of the wheel edge supporting shaft 9, the sun wheel 3 is assembled on the half shaft 1, the outer end face of the sun wheel 3 is axially limited by the retainer ring 2, the inner end face of the sun wheel 3 is flat with the end face of the spacer bush 4, and the hardness of the inner end face of the sun wheel 3 and the end face of the wheel edge supporting shaft is equivalent to that of the inner end face of the sun wheel 3 and the end face of the spacer bush 4, so that abrasion caused by direct contact of the sun wheel 3 and the end face of the wheel edge supporting shaft 9 is avoided.
The 3-ton loader drive axle wheel side spacer bush structure well solves the problems that in the prior art, due to the fact that the sun gear is in direct contact with the end face of the wheel side support shaft, the end face of the wheel side support shaft is abraded due to the fact that the hardness difference between the sun gear and the wheel side support shaft is too large, the shifting amount of the sun gear is increased, gear meshing is affected, the sun gear is meshed, the tooth beating faults are caused, and finally the drive axle wheel side damage faults are caused. Greatly improves the product quality and the service life, and reduces the three-pack cost of enterprises.
