摘要（英）：

The utility model discloses a novel low-noise handrail driving wheel for an escalator. The novel low-noise handrail driving wheel comprises a driving wheel body and is characterized in that a V-shaped groove is formed in the contact part between the driving wheel body and a handrail; and a plurality of circular arc notches are formed in the edge on the side wall of the V-shaped groove. The circular arc notches are formed in the edge on the side wall of the V-shaped groove, so that noises generated during combination and separation between the driving wheel body and the handrail can be greatly reduced.
