Abstract

The invention relates to a cutting speed reducer of a tunnel boring machine. A first-level sun gear is taken as an input shaft, and one end of the first-level sun gear is supported in a second-level planet carrier of an output shaft; a ring gear with left and right inner teeth is fixed on a box body; a shaft sleeve is arranged on the first-level sun gear, and a radial interval is arranged betweenthe shaft sleeve and a second-level sun gear; an inner hole of a first-level planet carrier is fixed on a deep groove ball bearing, wherein a radial interval is arranged between an inner ring of the deep groove ball bearing and the first-level planet carrier, and axial intervals are reserved between the deep groove ball bearing and the shaft sleeve as well as a stage of the first-level sun gear; the inner hole of the first-level planet carrier is connected with the second-level sun gear through a baffle, and an axial interval is arranged between the baffle and the second-level sun gear; the first-level planet wheel is arranged on the first-level planet carrier through a bearing and a shaft, and a second-level planet wheel is arranged on the second-level planet carrier through a bearing and a shaft; the first-level planet wheel, the first-level planet carrier and the second-level sun gear form basic components required by planet transmission flotation, and the axial limit is carried out by utilizing a rolling bearing; and the input shaft is provided with a main driven gear driving an oil pump and a lubrication system. The cutting speed reducer disclosed by the invention has the advantages of simple structure, high transmission efficiency, low cost, safety, reliability and the like.

Description

technical field [0001] The technology of the invention mainly relates to a planetary speed reducer, which is especially suitable for cutting speed reducers of roadheading machines. It belongs to a kind of deceleration mechanical equipment. Background technique [0002] Roadheaders are mainly comprehensive tunneling equipment used in coal, semi-coal and hard rock roadway mining. The working environment is harsh, the driving power of the working machine is large, and the impact and vibration during work are large. During the excavation process of the roadway, the cutting mechanism is required to continuously swing in pitch and horizontal direction. The whole mechanism is mainly composed of cutting mechanism, shipping mechanism, traveling mechanism, spraying, hydraulic and electrical systems. As the traveling mechanism advances, the cutting head in the working mechanism continuously breaks coal and rocks and transports them away. The cutting mechanism is the main work execut...
