7, the cooling employing water-cooling pattern of motor, and water-cooled type frequency convertor is housed on water cooled pipeline, the laying mode of motor cooling pipe and motor electricity cable is very reasonable simultaneously.The coal-winning machine that uses in deeply exploiting due to the girdle coalfield requires cutting power large, but be limited to again working face of coal seam to the restriction of coal-winning machine height; the cutting motor that fills on rocking arm can not the too large motor of power; and in order to satisfy the requirement of coal-winning machine cutting power; the method that high-power low seam mining machinery adopts a rocking arm that two cutting motors are installed increases cutting power, but this wiring for motor electricity cable and cooling pipe has proposed a difficult problem.In the present invention; all motor electricity cables and motor cooling pipe are all laid along the rib side (being that the coal-winning machine fuselage is near a side of rib) of coal-winning machine; like this; not only lay good motor electricity cable and cooling pipe convenient protected, and greatly reduced the pipeline quantity of old man's side.Simultaneously, be connected to the motor electricity cable of cutting motor can be easy with two cutting motor strings together, the wiring circuit is simple and be easy to protection.In addition, because the machine height of low seam mining machinery is low, fuselage is narrow, easily causes the pipeline extruding in the wiring of old man's side in the past, is difficult for protection, and affects workman's operation.In the present invention, motor electricity cable and cooling pipe are all protected under backplate, have greatly reduced the pipeline of coal-winning machine fore side, are easy to individual's operation, have prevented that effectively motor electricity cable and cooling pipe from being smashed by coal cinder or stone when coal-winning machine moves.
8, the reasonable in design of tractive unit planetary reduction gear and result of use are good, and input cost is low, the actual demand of especially suitable girdle coalfield coal-winning machine.Exploitation needs due to domestic thin layer complicated geological coal seam, the structure of coal-winning machine used is little and power is large, thereby the moment of torsion that the planetary reduction gear of axis of traction output need bear is large, due to the self structure requirement, planetary reduction gear is restricted in size radially, wants to meet the demands on intensity, just must strengthen the facewidth of planetary gear, the corresponding planet wheel spindle axial dimension that makes lengthens, but according to traditional four lines star wheel structure, the Rigidity and strength of planet wheel spindle is difficult to guarantee.The present invention has increased support together by set up the gripper shoe of putting more energy on planet carrier to planet wheel spindle, has improved the Rigidity and strength of planet wheel spindle.
Simultaneously, because the radial dimension of planetary reduction gear is restricted, the built-in bearing load of planetary gear is large, thereby existing self-aligning roller bearing can not meet actual needs in size and carrying.Thereby, in the present invention, the secondary planet wheel bearing is adopted special full type roller bearing, self is not with the outer ring this bearing, the planetary gear inwall is bearing outer ring ball track, so just having saved the transmission self aligning roller bearing outer ring takes up space, satisfying under the prerequisite of intensity, greatly reduced the physical dimension of planetary gear.
In sum, reasonable in design of the present invention, complete machine power is large, production efficiency is high and stable and reliable working performance, result of use are good, can solve effectively that the power that existing coal-winning machine exists is less, production efficiency is low, result of use is relatively poor in the thin seam mining process, have a strong impact on the multiple practical problem such as China's girdle complicated geological coal mining work.
