Abstract
The utility model relates to the constituent element of winning machine cutting part motor; be specially a kind of winning machine cutting part Motor torque axle protection mechanism; it is by motor, torque axis, bearing, bearing (ball) cover, and resilient protection disk, spacer, locking nut, spacing jump ring form.Solve the problem that ruptures and frequently change after torque axis overload.Described motor and torque axis are still used spline joint, and torque axis adopts end-toothed disc to be connected with cutting portion gear shaft, can convert torque loads to axial load.Torque axis is cancelled original cut groove structure, increases resilient protection disk at axle head, and this disk is provided with circular groove, in the time that axial load is excessive, thrusts at circular groove place, only needs to change this disk after fracture.Resilient protection disk outside adopts locking nut, spacing jump ring, unclamps spacing jump ring, locking nut, and torque axis entirety is outwards mobile, realizes the clutch between axle and cutting portion.The conversion of the utility model moment of torsion is simple in structure, reasonable in design reliable, has advantages of that easy replacing and cost are low.
Description
Technical field
The utility model relates to a kind of constituent element of the cutting portion Motor torque axle of mining, and is specially a kind of torque axis protection mechanism, belongs to coal mine equipment field.
Background technique
At present, winning machine cutting part Motor torque axle is usually designed to the form that has spron for two ends spline, one end, and in the time that cutting portion transships, torque axis ruptures at spron place, the torque axis then more renewing.This mode is brought two problems, and the one, be difficult for changing, when fracture, change workload large, the axis body of fracture is difficult for taking out, and while reinstalling, the spline of gear end is difficult for aligning; The 2nd, cost is high, and after fracture, torque axis is scrapped then and there, need again change, and single cost between units up to ten thousand, has reduced the working efficiency of coal winning machine several thousand, has increased the operating cost of coal winning machine.
Summary of the invention
The purpose of this utility model is to provide a kind of winning machine cutting part Motor torque axle protection mechanism.Motor and torque axis still adopt spline joint, and torque axis and cutting portion gear shaft adopt the Placement of end-toothed disc, when transferring power, torque loads are converted to axial load; One resilient protection disk is installed in protection mechanism, in the time that cutting portion transships, is only destroyed this resilient protection disk, not breakdown torque axle; Adopt spacing jump ring and locking nut structure, unclamp after spacing jump ring, locking nut, torque axis can entirety outwards move, and disconnects being connected between cutting portion, realizes clutch function.
Utilize this protection mechanism, only change low-cost resilient protection disk, after changing, torque axis adopts end tooth disc type to be connected with cutting portion gear shaft, and centering is easy, is convenient to install, and saves operating cost, indirectly improves the overall performance of coal winning machine.
Above-mentioned object realizes by following technological scheme:
Winning machine cutting part Motor torque axle protection mechanism, its composition comprises: motor, torque axis, resilient protection disk, spacing jump ring, locking nut, bearing etc.Described moment of torsion conversion function; Described overload protection function; Described clutch function.
Beneficial effect:
The utlity model has simple in structure, safe and reliable, be easy to safeguard, reduced cost of production, improved manufacturing efficiency.Brief description of the drawings:
Accompanying drawing 1 is structural representation of the present utility model.
End cap 2-bearing 3-electric machine casing 4-torque axis inside 1-motor
5-bearing, 6-spacer, 7-resilient protection disk, 8-motor cuts up with a hay cutter end cap outward
9-locking nut 10-spacing jump ring
Embodiment:
As shown in Figure 1, winning machine cutting part Motor torque axle protection mechanism, its composition comprises: end cap 8, locking nut 9, spacing jump ring 10 outside end cap 1, bearing 2, electric machine casing 3, torque axis 4, bearing 5, spacer 6, resilient protection disk 7, motor inside motor; Described torque axis 4 adopts end-toothed disc to be connected with cutting portion gear shaft, and the other end adopts resilient protection disk, the nut check of disk outside, and outermost is spacing with jump ring, and protection mechanism can normally be worked, and transfers torque load to axial load; 4 axial loads of described torque axis when larger, thrust resilient protection disk; Bearing 2,5 outer rings that described torque axis 4 supports use adopt loose fit, to guarantee to realize slip between outer ring and housing, make whole mechanism can easily realize clutch function; Once described resilient protection disk 7 damages are conveniently replaced, realize protection.
