The utility model has simple and compact structure, convenient processing and assembly and good lubrication effect, and solves the problems of damage to the differential mechanism assembly and failure of the drive axle assembly caused by unsmooth lubrication of the cross shaft and the bevel gear of the main transmission differential mechanism in the prior art.
Description
Technical Field
The utility model relates to the technical field of loader main drive differential mechanism assemblies, in particular to a lubricating structure for an inner hole of a bevel gear of a loader main drive differential mechanism and a cross shaft.
Background
The wheel loader in the domestic engineering machinery industry is often in a severe working environment, under the working conditions of iron powder, silt, cement and the like, impurities such as iron powder, wet sand and the like easily enter the inner cavity of a drive axle, the impurities enter the inner cavity of a gear and are mixed and stirred together with gear oil, the impurities slowly permeate into the inner hole matched with a cross shaft and a bevel gear, and cannot be discharged after entering the inner hole gap of the cross shaft and the bevel gear; in the loader operation, the cross shaft will be continuously rubbed by the impurities in the inner hole of the bevel gear, the cross shaft diameter and the inner hole of the bevel gear will be scratched and ground marks will be caused by the continuous friction of the impurities, because the fit clearance between the cross shaft and the inner hole of the bevel gear is originally small, the clearance between the bevel gear and the cross shaft becomes large when the operation is continued, the shaking amount of the bevel gear is large, so that the meshing tooth surface marks of the bevel gear and the half shaft gear deviate, the gear tooth beating fault occurs again, the assembly differential mechanism assembly is damaged, and finally the drive axle assembly is damaged, the operation cannot be continued, and the service life of the drive axle is reduced.
Disclosure of Invention
The utility model aims to provide a lubricating structure for an inner hole and a cross shaft of a bevel gear of a main transmission differential of a loader, which has the advantages of simple and compact structure, convenience in processing and assembly and good lubricating effect, and solves the problems that in the prior art, the main transmission differential is not smooth in lubrication of the cross shaft and the bevel gear, so that a differential assembly is damaged and a drive axle assembly is damaged.
In order to achieve the purpose, the lubricating structure of the inner hole of the bevel gear and the cross shaft of the main transmission differential of the loader comprises a bevel gear gasket 1, a bevel gear 3, a cross shaft 4, a differential case 5, a half-shaft gear gasket 6 and a half-shaft gear 7; the bevel gear 3 is provided with a bevel gear oil hole 2 and a bevel gear annular groove 8, wherein iron powder and greasy dirt impurities can be stored in the bevel gear annular groove 8, and the impurities are discharged through the bevel gear oil hole 2 when the bevel gear rotates; the bevel gear 3 and the bevel gear gasket 1 are arranged on the cross shaft 4 in tandem; the differential case 5 is mounted on a side gear 7, and a side gear spacer 6 is provided between the end face of the differential case 5 and the side gear 7.
When the loader works, the half shaft gear 7 rotates to drive the bevel gear 3 to rotate, the bevel gear 3 rotates around the cross shaft 4, and the bevel gear gasket 1 is sleeved on the cross shaft 4; because the gap between the bevel gear 3 and the cross shaft 4 is smaller, oil stains and impurities can be stored in the bevel gear annular groove 8 after entering the inner hole of the bevel gear 3; when the bevel gear 3 rotates, part of oil stains, impurities and the like are discharged from the bevel gear oil hole 2, so that the oil stains and the impurities at the upper end of the cross shaft are greatly reduced, the lubrication effect is improved, the defect that the differential bevel gear is damaged by tooth breaking of the differential bevel gear and the damage to the drive axle assembly caused by abrasion of the differential cross shaft 4 and the bevel gear 3 after the oil stains and the impurities enter is avoided, the main transmission damage fault of the drive axle is greatly reduced, and the service life and the reliability of the drive axle are improved.
The bevel gear inner hole and the cross shaft lubricating structure of the loader main transmission differential mechanism have the following technical characteristics and beneficial effects that the bevel gear oil hole and the annular oil storage groove are additionally formed in the bevel gear inner hole:
1. after the bevel gear inner hole is provided with the bevel gear oil hole 2 and the annular oil storage groove 8, oil dirt and impurities can be stored in the bevel gear annular groove 8 after entering the inner hole of the bevel gear 3 due to the smaller gap between the bevel gear 3 and the cross shaft 4; when the bevel gear 3 rotates, part of oil stains and impurities are discharged from the bevel gear oil hole 2, so that the oil stains and impurities at the upper end of the cross shaft are greatly reduced, the lubrication effect is improved, and the main transmission damage fault of the drive axle is greatly reduced;
2. the structure is simple and compact, and the processing and assembling process is simple.
