Therefore, it is important to improve the lubrication between the bevel gear spherical surface and the bevel gear shim.
Disclosure of Invention
The utility model aims at overcoming above-mentioned defect, provide a simple structure, preparation and maintenance cost are low, use safe and reliable's loader transaxle differential mechanism bevel gear oil groove lubricating structure, make iron powder and impurity in the middle of getting into bevel gear sphere and bevel gear gasket discharge from the oil groove in order to guarantee the cleanliness, improve lubricated effect, avoid bevel gear sphere and bevel gear gasket to produce wearing and tearing and cause the trouble that differential mechanism internal damage finally leads to the main drive assembly to damage.
In order to achieve the purpose, the bevel gear oil groove lubricating structure of the differential mechanism of the loader drive axle comprises a bevel gear gasket 1 and a bevel gear 3, wherein the bevel gear gasket 1 is attached to the spherical surface of the bevel gear 3 and is installed on a cross shaft 4 together with the spherical surface of the bevel gear 3, and the bevel gear gasket 1 is clamped on the cross shaft 4 and is fixed; the bevel gear 3 is meshed with a half shaft gear 7; a side gear spacer 6 is arranged between the differential case 5 and the side gear 7; the spherical surface of the bevel gear 3 is provided with an annular bevel gear spherical oil groove 2 which is not concentric with the bevel gear 3, the tangent position of the bevel gear spherical oil groove 2 and the bevel gear spherical surface is an oil inlet, the tangent position of the bevel gear spherical oil groove 2 and the bevel gear inner hole is an oil outlet, and the oil inlet and the oil outlet form a 180-degree angle with each other.
During operation, gear oil enters from the bevel gear spherical oil groove 2 and the bevel gear spherical tangent position, and then flows out from the bevel gear spherical oil groove 2 and the bevel gear inner hole tangent position to the spherical contact surface of the bevel gear gasket 1 and the bevel gear 3, so as to realize lubrication.
The lubricating structure for the bevel gear oil groove of the differential mechanism of the loader drive axle has the following technical characteristics and beneficial effects by arranging the bevel gear spherical annular oil groove:
1. iron powder and impurities entering the middle of the spherical surface of the bevel gear and the bevel gear gasket can be discharged from the oil groove, the cleanliness is ensured, and the lubricating effect is improved.
2. Simple structure, convenient processing and low manufacturing and maintenance cost.
The utility model discloses loader transaxle differential mechanism bevel gear oil groove lubricating structure has solved and has aroused abnormal sound, hairpin after getting into impurity and taking place bevel gear sphere wearing and tearing, wearing and tearing because in bevel gear sphere and the gear gasket gap, and then arouses the gear to collapse tooth, cross axle fracture trouble to finally lead to the inside trouble of damaging and the main drive assembly damage of differential mechanism.

Detailed Description
The following describes the lubrication structure of the bevel gear oil groove of the differential gear of the drive axle of the loader according to the present invention in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, the lubricating structure for the bevel gear oil groove of the differential mechanism of the loader drive axle of the present invention comprises a bevel gear gasket 1 and a bevel gear 3, wherein the bevel gear gasket 1 is attached to the spherical surface of the bevel gear 3 and installed on a cross axle 4, and the bevel gear gasket 1 is clamped on the cross axle 4 to be fixed; the bevel gear 3 is meshed with a half shaft gear 7; a side gear spacer 6 is arranged between the differential case 5 and the side gear 7; the spherical surface of the bevel gear 3 is provided with an annular bevel gear spherical oil groove 2 which is not concentric with the bevel gear 3, the A position where the bevel gear spherical oil groove 2 is tangent to the spherical surface of the bevel gear is an oil inlet, the B position where the bevel gear spherical oil groove 2 is tangent to the inner hole of the bevel gear is an oil outlet, and the oil inlet and the oil outlet form 180 degrees with each other, so that the gear oil enters from the A position and then flows out from the B position to the spherical contact surface of the bevel gear gasket 1 and the bevel gear 3 during working, and lubrication is realized.
During assembly, a bevel gear 3 with a bevel gear spherical oil groove 2 is sleeved into a cross shaft 4 and then sleeved into a bevel gear gasket 1, the bevel gear gasket 1 is in contact with the bevel gear spherical oil groove 2, a half axle gear gasket 6 is placed on the end face of a differential case 5 and then is installed into a half axle gear 7, and the bevel gear 3 is meshed with the half axle gear 7.
When the loader works, the half axle 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 clamped on the cross shaft 4 and does not rotate, namely, the spherical surface of the bevel gear 3 and the bevel gear gasket 1 generate friction; because of bevel gear 3 spherical surface processing has bevel gear spherical surface oil groove 2, impurity and iron fillings get into 3 spherical surfaces of bevel gear after along with bevel gear 3's rotation discharge from bevel gear spherical surface oil groove 2, spherical impurity and iron fillings have significantly reduced, lubrication effect has been improved, iron powder or other impurity in the gear oil have been avoided stirring into bevel gear spherical surface and bevel gear gasket wearing and tearing and have aroused the gear to beat the tooth, and then cause differential mechanism internal damage and finally lead to the trouble that the main drive assembly damaged, greatly reduced drive axle main drive assembly damage fault rate, the life and the reliability of drive axle have been improved.
The utility model discloses fine solution of loader transaxle differential mechanism bevel gear oil groove lubricating structure is because bevel gear sphere and bevel gear gasket are lubricated bad, arouses gear clearance grow, contact failure after producing wearing and tearing, arouses the gear again to beat tooth, cross axle fracture and finally lead to the problem of differential mechanism internal damage and main drive assembly damage.
