Description
Technical Field
The utility model relates to the technical field of loading hub reduction gear assemblies, in particular to a planet wheel gasket anti-rotation structure of a loading machine hub reduction gear.
Background
The engineering machinery wheel loader is often overloaded and continuously operated, and the working state of the loader is that the forward direction and the backward direction are frequently switched, i.e. the rotation direction of the wheel-side reducer assembly is frequently and continuously changed. The anti-rotation structure of the planetary wheel gasket of the conventional loader wheel-side speed reducer commonly adopts a bent anti-rotation piece and a wheel frame to limit, but because the rotation direction of the wheel-side speed reducer assembly is frequently and continuously changed, the anti-rotation piece is continuously collided with the wheel frame, and in addition, stress is concentrated at the bending position of the bent planetary wheel gasket during overload, so that the bent planetary wheel gasket is seriously worn and even the anti-rotation piece of the assembly is broken, the clamping failure of the wheel-side speed reducer assembly is finally caused, and the service life of equipment is reduced.
Disclosure of Invention
The utility model aims to overcome the defects, and provides the anti-rotation structure of the planetary wheel gasket of the wheel-side speed reducer of the loader, which has the advantages of simple structure, low manufacturing cost, reliable use and long service life of equipment, and solves the problem that the planetary wheel gasket in the prior art is easy to wear seriously and even break in actual operation to cause the clamping of the wheel-side speed reducer assembly.
In order to achieve the purpose, the planetary wheel gasket anti-rotation structure of the loader wheel edge speed reducer comprises a wheel carrier 1, a planetary wheel 2, a needle roller 3, a retainer ring 4, a planetary wheel gasket 5, a limiting block 6, a steel ball 7 and a planetary wheel shaft 8; the rolling needle 3 is assembled on an inner hole of the planet wheel 2, check rings 4 with limiting functions are assembled at two ends of the rolling needle 3, one surface of a planet wheel gasket 5 is attached to the planet wheel 2, the other surface of the planet wheel gasket is attached to the wheel carrier 1, a planet wheel shaft 8 passes through the inner hole of the planet wheel 2 and a wheel shaft hole of the wheel carrier 1 to fix the planet wheel 2 on the wheel carrier 1, and a steel ball 7 is assembled on a ball hole on the planet wheel shaft 8 to limit; the planetary wheel gasket 5 is round, a recess which is matched with each other is respectively arranged on the joint surface of the wheel frame 1 and the planetary wheel gasket 5 to form a groove, a square limiting block 6 is placed in the groove, and then the limiting block 6 and the wheel frame 1 are fixed by spot welding.
Above-mentioned loader wheel limit reduction gear planet wheel gasket prevents changeing structure, through increasing the notch that cooperates each other at the faying face of wheel carrier and circular planet wheel gasket one and forming the recess to put into a square stopper of preventing changeing in the recess, will prevent changeing the stopper again and the wheel carrier spot welding is fixed, has following technical characteristics and beneficial effect:
1. through adding the limiting block, the planetary gear gasket is not changed along with the change of the rotation direction of the wheel-side speed reducer any more, the planetary gear gasket can be effectively prevented from rotating and limiting, the phenomenon that the wheel-side speed reducer assembly is broken due to breakage of an anti-rotating piece in the prior art is avoided, and the service life of equipment is greatly prolonged;
2. the structure is simple and compact, corresponding parts are easy to process, the cost of the round planetary wheel gasket is lower than that of the bending planetary wheel gasket, and the manufacturing cost is low.

Fig. 1 is a schematic diagram of a main cross-sectional structure of an anti-rotation structure of a planetary wheel gasket of a wheel-side speed reducer of a loader.
Reference numerals: the planetary gear transmission mechanism comprises a wheel carrier 1, a planetary gear 2, a roller pin 3, a retainer ring 4, a planetary gear gasket 5, a limiting block 6, a steel ball 7 and a planetary gear shaft 8.
Detailed Description
The anti-rotation structure of the planetary wheel gasket of the loader wheel-side speed reducer is further described in detail below with reference to the accompanying drawings and specific embodiments.
The utility model discloses a planetary wheel gasket anti-rotation structure of a loader wheel-side speed reducer, which is shown in fig. 1 and comprises a wheel frame 1, a planetary wheel 2, a needle roller 3, a retainer ring 4, a planetary wheel gasket 5, a limiting block 6, a steel ball 7 and a planetary wheel shaft 8; the rolling needle 3 is assembled on an inner hole of the planet wheel 2, check rings 4 with limiting functions are assembled at two ends of the rolling needle 3, one surface of a planet wheel gasket 5 is attached to the planet wheel 2, the other surface of the planet wheel gasket is attached to the wheel carrier 1, a planet wheel shaft 8 passes through the inner hole of the planet wheel 2 and a wheel shaft hole of the wheel carrier 1 to fix the planet wheel 2 on the wheel carrier 1, and a steel ball 7 is assembled on a ball hole on the planet wheel shaft 8 to limit; the planetary wheel gasket 5 is round, a recess which is matched with each other is respectively arranged on the joint surface of the wheel frame 1 and the planetary wheel gasket 5 to form a groove, a square limiting block 6 is placed in the groove, and then the limiting block 6 and the wheel frame 1 are fixed by spot welding.
Through increasing stopper 6, make planet wheel gasket 5 no longer change along with the change of wheel limit reduction gear direction of rotation, can effectually prevent changeing spacingly to planet wheel gasket 5, avoided prior art because of preventing the cracked phenomenon that leads to wheel limit reduction gear assembly trouble of piece, greatly reduced cracked trouble of drive axle planet wheel gasket, improved the life and the reliability of transaxle.
