Loader drive axle planet wheel gasket anti-rotation structure

Abstract

A planet wheel provided with a roller pin is installed on a wheel carrier through a wheel shaft, the left end face and the right end face of the planet wheel are tightly attached to a left planet wheel gasket and a right planet wheel gasket respectively, and the planet wheel is meshed with an inner gear ring to form transmission. The wheel shaft is axially limited through a steel ball; limiting grooves are formed in the outer circle of the left planet wheel gasket and the outer circle of the right planet wheel gasket, and meanwhile a left limiting screw and a right limiting screw are additionally arranged on the wheel frame so that the left planet wheel gasket and the right planet wheel gasket can be prevented from rotating along with the planet wheel. The planet wheel gasket is simple and compact in structure, low in manufacturing and maintenance cost and safe and reliable to use, and solves the problems that due to the fact that a planet wheel gasket of a circular ring structure of a loading machine in the prior art does not have an anti-rotation function, particles generated by abrasion of a rear wheel frame after long-time use affect oil cleanliness and finally cause early abrasion of a planet wheel.

Description

Technical Field

[0001] The utility model relates to the technical field of planetary wheels of a driving axle of an engineering machinery loader, in particular to a planetary wheel gasket anti-rotation structure of a driving axle of a loader. Background Art

[0002] At present, a common planetary wheel gasket of the wheel-side reducer of a loader drive axle in the industry adopts a circular gasket structure. The planetary wheel gasket has the following disadvantages: First, the planetary wheel gasket with a circular structure has no anti-rotation function, and the planetary wheel gasket will rotate with the rotation of the planetary wheel. Since the end face of the planetary wheel gasket contacts the wheel frame, which is made of ductile iron, after long-term use, the particles generated by the wear of the planetary wheel gasket on the wheel frame can easily affect the cleanliness of the oil, and eventually cause early wear and failure of the planetary wheel. Summary of the Invention

[0003] The purpose of the utility model is to solve the above defects and provide a loader drive axle planetary wheel gasket anti-rotation structure with simple and compact structure, low manufacturing and maintenance costs, and safe and reliable use, so as to solve the problem that the planetary wheel gasket of the existing loader ring structure has no anti-rotation function, and the particles generated by the wear of the wheel frame after long-term use affect the cleanliness of the oil and ultimately cause early wear of the planetary wheel.

[0004] To achieve the above purposes, the planetary gear gasket anti-rotation structure of the loader drive axle of the present invention includes an inner ring gear 1, a left planetary gear gasket 2, a left limit screw 3, a wheel frame 4, a needle roller 5, a right planetary gear gasket 6, a planetary gear shaft 7, a steel ball 8, a right limit screw 9 and a planetary gear 10; the planetary gear 10 equipped with a needle roller 5 is installed on the wheel frame 4 through the wheel shaft 7, and the left and right end surfaces of the planetary gear 10 are respectively close to the left planetary gear gasket 2 and the right planetary gear gasket 6, and the planetary gear 10 and the inner ring gear 1 are engaged to form a transmission; the wheel shaft 7 is axially limited by the steel ball 8; the outer circles of the left planetary gear gasket 2 and the right planetary gear gasket 6 are provided with a limit groove 11, and the left limit screw 3 and the right limit screw 9 are added to the wheel frame 4 to prevent the left planetary gear gasket 2 and the right planetary gear gasket 6 from rotating with the planetary gear 10.

[0005] The planetary gear gasket anti-rotation structure of the loader drive axle of the above structure has the following technical features and beneficial effects through optimized design:

[0006] 1. By changing the original circular ring structure planetary gear gasket to an outer circle with a limiting groove structure and adding limiting screws to the wheel frame, the left and right planetary gear gaskets can be effectively prevented from rotating with the planetary gear, greatly reducing the wear of the wheel frame by the planetary gear gasket, ultimately improving the reliability of the drive axle. This solves the problem of the existing circular ring structure planetary gear gasket of the loader, which has no anti-rotation function and the particles generated by the wheel frame after long-term use affect the cleanliness of the oil and eventually cause early wear of the planetary gear.

[0011] The specific implementation of the planetary gear gasket anti-rotation structure of the loader drive axle of the present invention is further described in detail below with reference to the accompanying drawings.

[0012] Figure 1-Figure 2 As shown, the planetary gear gasket anti-rotation structure of the loader drive axle of the present invention includes an inner ring gear 1, a left planetary gear gasket 2, a left limit screw 3, a wheel frame 4, a needle roller 5, a right planetary gear gasket 6, a planetary gear shaft 7, a steel ball 8, a right limit screw 9 and a planetary gear 10; the planetary gear 10 equipped with a needle roller 5 is installed on the wheel frame 4 through the wheel shaft 7, and the left and right end surfaces of the planetary gear 10 are respectively close to the left planetary gear gasket 2 and the right planetary gear gasket 6, and the planetary gear 10 and the inner ring gear 1 are engaged to form a transmission; the wheel shaft 7 is axially limited by the steel ball 8; the outer circles of the left planetary gear gasket 2 and the right planetary gear gasket 6 are provided with a limit groove 11, and the left limit screw 3 and the right limit screw 9 are added to the wheel frame 4 to prevent the left planetary gear gasket 2 and the right planetary gear gasket 6 from rotating with the planetary gear 10.

[0013] The above-mentioned loader drive axle planetary gear gasket anti-rotation structure changes the original circular ring structure planetary gear gasket into an outer circle with a limiting groove structure, and adds a limiting screw on the wheel frame, which can effectively prevent the planetary gear gasket from rotating with the planetary gear. When the loader drive axle is working, the planetary gear 10 rotates, the limiting groove 11 of the left planetary gear gasket 2 is stuck in the left limiting screw 3, and the limiting groove 11 of the right planetary gear gasket 6 is stuck in the right limiting screw 9. The contact surfaces of the left planetary gear gasket 2 and the right planetary gear gasket 6 and the wheel frame 4 will not produce relative rotation, and the mating end faces of the planetary gear gaskets of the wheel frame 4 will not cause wear, thereby effectively avoiding the situation where the wheel frame 4 is worn and the particles are generated to affect the cleanliness of the oil, greatly improving the cleanliness of the oil, and ultimately improving the reliability of the drive axle.
