The union structure of the power transfer axis and gear in a vinyl opening and closing machine with braking both direction function

摘要

The present invention relates to a coupling structure of a power transmission shaft and a gear in a vinyl switchgear having a bidirectional braking function, and an object thereof is to simplify the processing and assembly of the power transmission shaft and the gear when the gear is moved to the power transmission shaft.;At the point where the gear is located in the power transmission shaft constituting the vinyl switchgear, the inclined guide groove is formed, and the inner diameter of the gear coupled thereto is configured to combine with each other by forming a guide protrusion.;The present invention configured as described above is characterized in that the guide projection of the gear is positioned in the inclined guide groove of the power transmission shaft, the movement of the gear is made in accordance with the rotation direction of the handle, and the processing and assembly are easy in the means of transmitting power.
