One end of the wire is connected to the rotating shaft of the motor and the other end of the wire is connected to the blade, and the power transmission gear of the stirrer for concrete compaction that vibrates the poured concrete by rotating the blade of the motor rotates the blade. In the power transmission gear of the stirrer for concrete compaction, the gear is coupled, and the wire coupling shaft to which the wire is correspondingly connected is coupled to the driven helical gear 20.
One end of the flexible wire is coupled to the shaft of the driven helical gear 20, the other end of the wire is coupled to the impeller shaft, the wire is inserted into the flexible hose and rotated, and the impeller case is coupled to the end of the hose, and the impeller case Since the impeller shaft is supported by the bearing and the rotation is coupled smoothly, the rotation of the motor rotates the impeller through the wire,
The driving helical gear and the driven helical gear 20 are chamfered at the corners to form an inclined surface 1, so that air flows smoothly between the inclined surfaces 1 and prevents damage to the corners.
The driven helical gear 20 is composed of a body 21 to which a wire is coupled, and a tooth 22 formed on an opposite side of the body 21 to be coupled to a driving helical gear, and the body 21 and a toothed portion. Between the 22 is the connection portion 25 is formed,
The teeth 22 are divided into 1 and 2 teeth 23 and 24 and are simultaneously coupled to the drive helical gear tooth surface.
The first and second teeth 21 and 22 are spaced in the axial direction at a predetermined interval, so that the air flows smoothly between the spaced intervals of the first and second teeth so that the driving helical gear and the driven helical gear 20 are powered. Cooling the heat generated is increased,
A groove is formed at one side of the body 21 to insert one end of the wire, and penetrate the upper and lower parts of the body to simultaneously fasten the pin or bolt through the hole formed at one end of the wire.
The connecting portion 25 has a rod shape smaller than the diameter of the body 21 and the teeth 22, the corner portion connected to the body 21 is formed with a round (2) and the corner portion of the body 21 is chamfered And the inclined surface 1 is formed, the corner portion connected to the teeth 22 is formed with a round 2 and the corner portion of the teeth 21 is chamfered, characterized in that the inclined surface 1 is formed.
