Abstract
The present invention 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 are formed.The problem that after solving torque axis overload, fracture is frequently changed.Described motor and torque axis still use spline joint, and torque axis and cutting portion gear shaft adopt end-toothed disc to be connected, and can convert torque loads to axial load.Torque axis cancels original cut groove structure, and increase resilient protection disk at axle head, this disk is provided with circular groove, thrusts at circular groove place when axial load is excessive, only needs to change this disk after fracture.Adopt locking nut, spacing jump ring outside resilient protection disk, unclamp spacing jump ring, locking nut, torque axis entirety can outwards movement, realizes the clutch between axle and cutting portion.Torque converted configuration of the present invention is simple, reliably reasonable in design, has and easily changes and the low advantage of cost.
Description
Technical field
The present invention relates to a kind of constituent element of cutting portion Motor torque axle of mining, be specially a kind of torque axis protection mechanism, belong to coal mine equipment field.
Background technique
At present, the form that winning machine cutting part Motor torque axle is typically designed as two ends spline, there is spron one end, when cutting portion transships, torque axis ruptures at spron place, the torque axis then more renewed.This mode brings two problems, and one is not easily change, and change workload during fracture large, the axis body of fracture not easily takes out, and when reinstalling, the spline of gear end not easily aligns; Two is that cost is high, and after fracture, torque axis is scrapped then and there, need again change, and single cost, between several thousand to unit up to ten thousand, reduces the working efficiency of coal winning machine, adds the operating cost of coal winning machine.
Summary of the invention
The object of the present invention 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, convert torque loads to axial load while transferring power; Install a resilient protection disk in protection mechanism, this cushion disk(-sc) is provided with a series of circular groove on thickness, and when cutting portion transships, this resilient protection disk is first destroyed, and not breakdown torque axle; Adopt spacing jump ring and locking nut structure, after unclamping spacing jump ring, locking nut, torque axis can be overall outwards mobile, disconnects the connection between cutting portion, realize 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, saves operating cost, indirectly improve the overall performance of coal winning machine.
Above-mentioned object is realized 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:
It is simple that the present invention has structure, safe and reliable, is easy to safeguard, reduces cost of production, improve manufacturing efficiency.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of invention.

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 and cutting portion gear shaft adopt end-toothed disc to be connected, and the other end adopts resilient protection disk, and with nut check outside disk, outermost jump ring is spacing, and protection mechanism can normally work, and transfers torque load to axial load; When the axial load of described torque axis 4 is larger, resilient protection disk is thrust; Bearing 2,5 outer ring that described torque axis 4 supports adopts loose fit, to guarantee realize between outer ring and housing sliding, makes whole mechanism easily can realize clutch function; Described resilient protection disk 7 is once damage, conveniently replaced, realizes protection.
