Zusammenfassung:	The utility model discloses a drive belt tensioning device which comprises a tensioning wheel. The tensioning wheel is movably connected with a tensioning wheel shaft through an upper bearing and a lower bearing, the lower end of the tensioning wheel shaft is connected with a tensioning wheel seat plate, the tensioning wheel shaft is fixedly connected with the tensioning wheel seat plate through a locating pin, and the upper end of the tensioning wheel shaft is fixedly provided with an elastic damping ring for shafts. By utilizing the locating pin to fix the tensioning wheel shaft on the tensioning wheel seat plate, deformation of the tensioning wheel shaft does not occur, and perpendicular degree between the tensioning wheel and the tensioning wheel seat plate can be easily guaranteed. By utilizing the bearings to achieve the connection between the tensioning wheel and the tensioning wheel shaft, rolling friction is generated between the tensioning wheel and the tensioning wheel shaft, so noise is extremely
