Problems solved by technology
[0006] Due to the complex geological conditions of coal mines, continuous miners often cause great impact when cutting hard rocks, and a large amount of dust will also cause damage to rolling bearings 14', floating seals 15' and other components inside the cutting reducer.
After the bearing, floating seal 15' and other components of the above-mentioned cutting reducer are damaged, the entire long horizontal shaft 11' needs to be disassembled to be taken out for maintenance and replacement. However, the conditions and space in the coal mine are very limited and cannot be disassembled. If there is no solution, the cutting reducer will be replaced directly, resulting in very expensive maintenance costs

The invention discloses a cutting speed reducer, which comprises two symmetrically-arranged speed reduction devices (1), wherein the two speed reduction devices (1) are used for synchronously transmitting power and comprise two cutting main shafts (11) distributed in a straight line and a connection sleeve (12) arranged between the two cutting main shafts (11); the two cutting main shafts (11) are connected to the output ends of the two speed reduction devices (1) respectively and are connected with each other through the connection sleeve (12); and a bearing (13) and a floating seal (14) of the speed reduction devices (1) are sleeved on the inner sides of the two cutting main shafts (11). The cutting speed reducer has a simple assembly; and after easily-damaged parts such as the bearing inside the cutting speed reducer and the like are damaged, the damaged parts can be exchanged under a mine so as to reduce the cost. The invention also discloses a continuous miner, which comprises a cutting part (5), wherein the cutting speed reducer is used in the cutting part (5); and the continuous miner has a corresponding technical effect.
Description
technical field [0001] The invention relates to the technical field of mining machinery, in particular to a cutting speed reducer for a continuous coal mining machine. The present invention also relates to a continuous coal mining machine comprising the above-mentioned cutting reducer. Background technique [0002] With the rapid development of my country's economic construction, the coal industry continues to develop in the direction of mechanization and automation, and comprehensive mechanized coal mining equipment is more and more widely used in coal production under various geological conditions. [0003] The continuous coal miner is a comprehensive coal mining equipment used in coal mines that integrates roadway excavation and coal mining. It includes cutting parts, mobilizing walking parts, loading systems and spray dust removal systems, etc., equipped with shuttle cars, belt conveyors and anchors. After pole support, comprehensive mechanized coal mining can be realiz...
