PROBLEM TO BE SOLVED: To perform an effective noise damping processing easy to be carried out to a toothed belt transmission system of a servo steering device. SOLUTION: This toothed belt transmission system 1 is structured by engaging a toothed belt 2 with a first and a second toothed pulleys 3 and 4. This transmission system is provided with at least one of following structure. First, a pitch difference exists between the toothed pulley 3 and the toothed belt 2. Second, the toothed pulley 3 has helical teeth and the toothed belt 2 has straight teeth. Alternatively, the toothed pulley 3 has the same or a little different angle of inclination with/from the toothed belt 2. COPYRIGHT: (C)2007,JPO&INPIT |
