The invention relates to an important part of coal mine roadway excavation and mining machines, particularly relates to a driving speed reducing device for use in a driving part of a continuous mining machine and solves the problems such as low strength caused by the limitation of machine height and the complex structure of the driving speed reducing device of the driving part of the prior continuous mining machine. The driving speed reducing device is a ring gear output closed differential gear train. The output ring gear of the driving speed reducing device and the output chain wheel of thedriving part are integrated to reduce the install space of the ring gear and the driving chain wheel and increase the strength of a driving piece. The driving speed reducing device is simple and compact in structure, convenient in maintenance and capable of greatly improving driving efficiency and has the advantages of high strength and high reliability.
Description
technical field [0001] The invention relates to an important part of coal mine roadway excavation and mining machinery, in particular to a traveling deceleration device for the traveling part of a continuous mining machine. Background technique [0002] At present, the travel deceleration device of the traveling part of the continuous mining machine used in coal mines is a transmission system consisting of five stages of torque transmission through spiral bevel gear transmission, parallel shaft transmission, and planetary transmission. Its structure is complex, the efficiency loss is large, and installation and maintenance are inconvenient. Therefore, there is a great need for a travel deceleration device with simple structure, reliable function, and convenient installation and maintenance. Contents of the invention [0003] In order to simplify the structure of the existing walking deceleration device of the continuous mining machine, improve the transmission efficiency, ...
