Beschreibung
Zusammenfassung:	The utility model provides a drilling machine tapping speed reducing device which comprises an input shaft, an output shaft, a driving gear, a driven gear and a tapping clamp. The driving gear is positioned on the input shaft, the driven gear is arranged on the output shaft, the tapping clamp is in transmission connection with the output shaft or the driven gear, the driving gear and the driven gear are meshed, and the tooth number of the driving gear is smaller than that of the driven gear. By means of meshed transmission of gears, high rotation speed of a drilling machine spindle can be changed into low rotation speed required by tapping. Thus, screw tapping fracture is effectively avoided, and labor intensity of workers is reduced simultaneously.
