Abstract (en)
A drive assembly for a grinder has a housing device (20), a drive device (30), multiple transmission devices (40) and multiple grinding devices (50). The drive device (30) has a motor (31), a driving wheel (32) and a driving band (33) connected with the motor (31) and the driving wheel (32). Each transmission device (40) has a transmission wheel (41,41A), multiple driven wheels (42) and a transmission band (43). Each transmission band (43) is engaged the driven wheels (42) and the transmission wheel (41,41A) engaged the driving band (33). With two-layer arrangement of the bands, the driving band (33) and the transmission bands (43) are not long and can be rotated smoothly to reduce energy waste. Accordingly, the motor's (31) load is greatly reduced, and lifespans of the driving band (33) and the transmission bands (43) are prolonged.
