Description
Technical Field
The utility model relates to a loader transaxle equipment technical field, concretely relates to 5-6 tons heavy load type loader transaxle wheel limit ring gear assembly.
Background
The wheel loader in the engineering machinery industry usually works continuously under overload and overload conditions, the torque is large and the speed is low when a drive axle of the loader works so as to meet the maximum traction force of the whole machine, at the moment, the inner gear ring at the wheel edge of the drive axle bears large load, and the stress direction of the inner gear ring is also changed continuously due to the working property of the loader which is continuous in advancing and retreating, so that a severe test is formed on the strength of the inner gear ring. The inner gear ring in the prior art is generally integrated, the tooth profile of the inner gear ring adopts a gear shaping processing technology during processing, the technology has low tooth profile precision and large deformation, the problems of meshing marks and meshing gaps of the inner gear ring and the planet gear are easy to occur, and after long-term operation, the tooth surfaces of the inner gear ring and the planet gear are in poor engagement, so that the tooth surfaces of the inner gear ring and the planet gear are peeled off and other faults are caused; if the loader continues to work, the inner gear ring continuously bears unbalanced force to cause the gear of the inner gear ring to be damaged, so that the wheel side assembly and the drive axle assembly are damaged.
Disclosure of Invention
The utility model aims at providing a 5-6 ton heavy load type loader transaxle wheel limit ring gear assembly that ring gear machining precision is high, the quality is reliable, long service life solves among the prior art because of the bad ring gear processing technology that arouses ring gear beat the tooth damage and finally lead to the unable normal problem of work of loader.
In order to achieve the above purpose, the wheel-side inner gear ring assembly of the drive axle of the 5-6 ton heavy-duty loader of the utility model comprises a planet wheel carrier 1, a steel ball 2, a planet wheel shaft 3, a planet wheel gasket 4, a spacer ring 5, a planet wheel 6, a roller pin 7, an inner gear ring 8, a baffle ring 9, an inner gear ring support seat 10 and a support shaft 11; the roller pin 7 and the spacer 5 are assembled in an inner hole of the planet wheel 6, the planet wheel gasket 4 is respectively arranged on the end faces of two sides of the planet wheel 6, the planet wheel shaft 3 is sleeved into the planet wheel carrier 1, and the planet wheel shaft 3 is fixed on the planet wheel carrier 1 through the steel ball 2, so that the planet wheel 6 can only rotate; the inner gear ring 8 and the gear ring support seat 10 are in a split type, the inner gear ring 8 is in a through structure, the two retainer rings 9 fix the inner gear ring support seat 10 on the inner gear ring 8 to form an inner gear ring assembly, and the inner gear ring support seat 10 is assembled on the support shaft 11.
The 5-6 ton heavy-duty loader driving axle wheel-side inner gear ring assembly with the structure has the following technical characteristics and beneficial effects that the inner gear ring is separated from the gear ring supporting seat, and the inner gear ring is processed by adopting a tooth broaching process:
1. the inner gear ring and the gear ring supporting seat are processed separately and are fixed by a clamping ring;
2. the inner gear ring has high machining precision and small gear deformation, and the quality of the inner gear ring assembly is improved.
The utility model discloses 5-6 ton heavy load type loader transaxle wheel limit ring gear assembly has solved because of ring gear shaping processing technology is bad, the machining precision is low, arouses ring gear to beat the tooth and damages to finally lead to the unable problem of normal work of loader.
