Abstract
The utility model relates to components of a coal cutter cutting motor torque shaft, in particular to a coal cutter cutting motor torque shaft and solves the problems that the machining is difficult, the accuracy is difficult to guarantee or torque shafts are frequently broken during usage in terms of structural designs of the existing torque shafts. A V-shaped groove with a circular arc bottom is disposed at a stress concentration position of the torque shaft. The coal cutter cutting motor torque shaft has the advantages that the structural design is reasonable and reliable, the convenient machining is guaranteed, simultaneously, excess stress concentration is avoided, the problem of frequently breaking of the torque shafts is solved, further the times of maintenance are reduced, the production efficiency is improved, the structure is simple, and the cost is low.
Description
Technical field
The utility model relates to the constituent element of coal winning machine cutting motor, is specially a kind of coal winning machine cutting motor torque axis.
Background technique
Using torque axis in the coal winning machine cutting motor hollow shaft is the good method that transmission system elastic buffer link is set, and along with developing rapidly of China's coal-mine Mechanization Level, studies and grasps this new technology and seem very important.
Torque axis is as the pto＝power take-off of cut motor; at first play the effect of transmitting torque between cutting motor and transmission system; secondly when winning machine cutting part is in bad working environments because of serious overload; torque axis can rupture at stress raiser, thereby plays the effect of protection transmission system.
Existing torque axis is many to have " U " shape groove or " V " shape groove at its stress raiser, is used for transferring power and overload protection, and effect is all fine.Yet the design of " U " shape groove of torque axis is dark and narrow, and processing difficulties, dimensional accuracy are difficult to guarantee; " V " shape groove design stress undue concentration of torque axis frequently ruptures during use, and is very inconvenient.
Summary of the invention
The problem of the utility model frequent fracture in order to solve existing moment of torsion structural design of shaft and to exist processing difficulties, precision to be difficult to guarantee or using provides a kind of coal winning machine cutting motor torque axis.
The utility model is to adopt following technological scheme to realize: coal winning machine cutting motor torque axis, the stress raiser of described torque axis have the bottom and are circular-arc V-type groove.
The V-type groove design of torque axis is so that easy to process, the V-type groove bottom is arc transition simultaneously, is unlikely to the stress undue concentration, in the using process, torque axis can frequently not rupture, and has overcome existing moment of torsion structural design of shaft and has existed processing difficulties, precision to be difficult to guarantee or the problem of frequent fracture when using.
The angle of V-type groove is 80 °, and the radius of arc of V-type groove root is 3cm, has further improved the usability of torque axis.
The utility model reasonable in design is reliable, guarantees to be unlikely to the stress undue concentration time easy to process, avoids the problem of the frequent fracture of torque axis, and then reduces maintenance frequency, has improved manufacturing efficiency, has advantage simple in structure and that cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-torque axis, 2-V type groove.
Embodiment
Coal winning machine cutting motor torque axis, the stress raiser of described torque axis 1 have the bottom and are circular-arc V-type groove 2.
The angle of V-type groove 2 is 80 °, and the radius of arc of V-type groove 2 roots is 3cm.
