Abstract
The utility model discloses a transmission mechanism of a traction part of a coal cutter. The transmission mechanism comprises a transmission box, wherein the left side of the transmission box is in power connection with an active gear and the right side is connected with a walking shaft; a first stage transmission mechanism which is in power connection with the active gear and a second transmission mechanism which drives the walking shaft to rotate are installed at the left and right sides of the transmission box respectively; and the first stage transmission mechanism and the second stage transmission mechanism are in power connection through a main axis. According to the utility model, two stages of speed reduction transmission mechanisms are arranged separately; the structure is simple and reasonable; the machine thickness of the traction part of the coal cutter is reduced; the machine height of the coal cutter is reduced and the coal passing height is increased, so that the coal output is increased.
Description
Technical field
The utility model relates to a kind of shearer hauled-part transmission mechanism.
Background technology
Existing coal-winning machine comprises fuselage, be installed in power setting part, cylinder, the traction element on the fuselage and be installed in the walking axis of traction element below, and the road wheel in the drag conveyor walking is housed on the walking axis.Traction element comprises the transmission case that is connected with power set power; Power transmission shaft and reduction gearing are housed in the transmission case, the walking gear engagement on reduction gearing and the walking axis, the transmission case middle part volume of this structure is big; Height between the middle plate of power transmission shaft and travelling gear and drag conveyor is a underneath clearance; Thereby causing underneath clearance little, the fuselage height of coal-winning machine is big, influences coal mining output.
The utility model content
The technical problem that the utility model will solve provides the big shearer hauled-part transmission mechanism of a kind of underneath clearance.
For solving the problems of the technologies described above; The shearer hauled-part transmission mechanism that is provided comprises left side and the transmission case that driving gear power is connected, the right side is connected with walking axis; Its design feature is: the transmission case left and right sides is equipped with one-level transmission mechanism that is connected with driving gear power and the secondary transmission mechanism that drives the walking axis rotation respectively, connects through main shaft power between one-level transmission mechanism and the secondary transmission mechanism.
Said one-level transmission mechanism comprises first ring gear that is installed in the transmission case left side and first planet carrier that is rotatably connected in first ring gear; Be rotatably connected to first sun gear in first ring gear with the driving gear engagement; First planet carrier is connected with a plurality of first planetary gears with the engagement of first sun gear, and the left part of said main shaft is provided with the Zuo Zhongchuan wheel that is connected with the first planet carrier power.
Said secondary transmission mechanism comprises second ring gear that is installed in the transmission case right side and second planet carrier that is rotatably connected in two ring gears; Second planet carrier is connected with a plurality of second planetary gears; The right part of said main shaft is provided with the right sun gear with the engagement of second planetary gear, and second planet carrier is connected with walking axis power.
After adopting said structure; Owing to transmission mechanism is set in the both sides of transmission case; Two sets of transmission mechanism connect through main shaft, thereby the middle part of transmission case can attenuation, the i.e. attenuation of shearer hauled-part central fuselage; Thereby increased the height between transmission case middle part and the drag conveyor middle part, promptly increased underneath clearance.
In sum, the utility model is arranged double reduction transmission mechanism branch, and is simple and reasonable, reduced shearer hauled-part fuselage thickness, reduced the fuselage height of coal-winning machine and strengthened underneath clearance, the raising of the output that helps mining.
