Drive system for cutting rollers of document shredder - drives two rollers by electric motor via worm gear with rollers connected to U=shaped steel plate

摘要

The drive system (3) of a document shredder has an electro-motor (4) driving both rollers (1, 2) in opposite directions via a gear (5). The drive system and both rollers are connected to a steel plate U-shaped carrier. The rollers are located on the bridge (8) of the U on two locating blocks (7). The gear (5) is an angled gear, pref. a worm gear (9) having an toothed rack (11), connected to the motor drive shaft (10), which engages a gear wheel (12). ADVANTAGE - Electro motor can be arranged alongside, above or below cutting rollers reducing length of device. Enables improved adaption to container dimensions and more compact construction.
