PULLEY FOR CRAWLER BELT

PROBLEM TO BE SOLVED: To provide a pulley for a crawler belt capable of obtaining a sufficient propulsive force while preventing deviation (coming off) of the crawler belt. SOLUTION: Pulley teeth 7 are formed on an outer peripheral surface of a pulley body 4. A flange 5 is provided on both end parts in the central axis direction of the pulley body 4. The crawler belt 2 is wound on the pulley body 4. The outer peripheral part of the flange 5 is projected further to the outside in the radial direction than the outer peripheral part of the crawler belt 2. The tooth part 10 is provided as a slip stopper to prevent a slip relative to a traveling surface 3. The sufficient propulsive force is obtained by a friction force between the flange 5 and the traveling surface 3. The crawler belt 2 is lifted up from the traveling surface 3, and it is blocked that a lateral force acts on the crawler belt 2. The deviation (coming off) of the crawler belt 2 from the pulley boy 4 is prevented. COPYRIGHT: (C)2006,JPO&NCIPI
