Problems solved by technology
On the one hand, the design space of the wheel-side reduction device is limited by the size of the rim space, especially the diameter of the planetary gear system is difficult to expand; on the other hand, the arrangement of briquetting blocks for super-large-tonnage mining dump trucks is likely to cause the rim to slip during operation Cutting off the valve tube causes a safety accident
Problems existing in the integral rim coupling plate in the prior art, such as relatively difficult assembly and disassembly, unfavorable size design of matching parts, etc.

Embodiment Construction
[0022] like Figure 1 to Figure 4 The shown kind of mine dumping wheel side deceleration assembly includes a rear axle housing 3, and the rear axle housing 3 is connected with a wheel side deceleration device assembly 4, and the wheel side deceleration device assembly 4 is connected by a spliced rim. The disc 2 is connected with a rim assembly 5 , and the tire 1 is provided outside the rim assembly 5 . The wheel side reduction device assembly 4 includes a wheel hub 4-1, a secondary planetary gear train 4-2 and a torsion tube 4-3. In the mine self-unloading wheel deceleration assembly of the present invention, the wheel deceleration device assembly is connected to the wheel rim assembly through a spliced wheel rim connecting disc. It is installed on the side to avoid penetration from the outside of the wheel reducer device, which not only provides convenience for disassembly and assembly, but also facilitates the optimization of the internal structure design. We strive fo...

The invention discloses a wheel-side speed reduction assembly of a mining dump truck and an installation method of the wheel-side speed reduction assembly. The wheel-side speed reduction assembly comprises a rear axle housing, the rear axle housing is connected with a wheel-side speed reduction device assembly, the wheel-side speed reduction device assembly is connected with a rim assembly through a splicing type rim connecting disc, and a tire is arranged outside the rim assembly. According to the wheel-side speed reduction assembly of the mining dump truck and the mounting method of the wheel-side speed reduction assembly, the rim connecting disc is convenient to mount and dismount, and the maintainability of the mining dump truck can be improved; interference with other parts is avoided in the mounting and dismounting process, the design space of the other parts is increased, and a transmission system with higher power is designed; and a certain distance is reserved between the two tires, so that maintenance personnel can conveniently enter to check the loosening condition of the bolts on the inner side.
Description
technical field [0001] The invention relates to the technical field of construction machinery, in particular to a mine dump wheelside deceleration assembly and an installation method thereof. Background technique [0002] As one of the important key equipments in open-pit mine mining and transportation and large-scale earthwork construction, the mining dump truck can carry a load of 400 tons, and the wheel-side reduction device transmits a torque of more than one million Nm. Its design has always been a difficult problem. On the one hand, the design space of the wheel-side reduction device is limited by the size of the rim space, especially the diameter of the planetary gear train is difficult to expand; on the other hand, the arrangement of the pressure blocks for the super-large tonnage mining dump truck is likely to cause the rim to slip during operation. Cut the valve tube to cause a safety accident. The problems existing in the integrated rim connecting disc in the pri...
