Abstract

The present invention relates to a mining machine, in particular to a walking speed reducer and a mining machine with the walking speed reducer. The walking speed reducer includes: a box body and a first speed reduction device and a second speed reduction device installed in the case body, The first reduction device includes: a reduction gear set for connecting the drive motor; and a planetary reduction assembly drivingly connected with the reduction gear set; the second reduction device includes; a planetary reduction output shaft gear, a first idler assembly, and a large input The gear shaft assembly, by installing the planetary reduction assembly on the outside of the sprocket assembly, and driving the connected planetary reduction output shaft gear, first idler gear assembly and input large gear assembly in parallel to drive the sprocket assembly. The travel reducer with this structure has a large transmission ratio and a large output torque. The final power output of the travel reducer is transmitted through the large side gear, and the sprocket can be small and the driving force is large.

Description

technical field [0001] The invention relates to a mining machine, in particular to a travel speed reducer and a mining machine with the travel speed reducer. Background technique [0002] At present, due to the limitation of the space of the roadway, the dimensions of the roadway excavation and mining machinery are limited. Among them, the drive of the walking traction device should consider providing sufficient output torque and driving force even when the space of the whole machine is limited. The commonly used technical solution is The planetary deceleration of the travel reducer is built inside the driving sprocket, and the sprocket is driven by the inner ring gear or the planet carrier; this kind of scheme is due to the existence of the internal planetary transmission structure, and the size of the sprocket is relatively large. In the case of driving the sprocket transmission, the linear speed of the sprocket is fast and the driving force is insufficient, which in turn ...
