A sprocket wheel for chain roller of engatamento random with engrazamento staggered and deliverance of the flank in order to provide caracterìsticas of ruìdo improved
Invention patent: b "sprocket for chain roller of engatamento random with staggered mesh and deliverance of flank.In order to provide caracteru00ecsticas of ruu00ecdo improved '' d .The sprocket wheel chain rollers random shift for use primarily in applications of chain drive of motor vehicle engines.Which incorporates different profiles of asymmetric teeth for improved noise reduction.In particular, the sprocket includes a first plurality of teeth of the sprocket wheel, each having a first profile of a tooth, including a first side shift.A first root of gearing and a first flat surface positioned between the first side of the first root shift and shift, in which a first roller initially.Contacts the first flat surface at the beginning of the first roller mesh with the sprocket.The sprocket wheel also includes a second plurality of teeth of the sprocket wheel, each having a second profile of the tooth.Different from the first tooth profile and including a second side shift, a second root of gearing and a second flat surface tangent to the second root of gearing.Away from the second edge shift and a second roller initially contacts the second flat surface at the beginning of the mesh between the second roller and the sprocket.
