BELT Russian patent published in 2011 - IPC F16G1/28 F16G5/20 

FIELD: machine building.

SUBSTANCE: belt has top of teeth interacting with specified part of sprocket recess so, that tension cord is maintained in arc-shape between bases of teeth. A system of the belt and sprocket has the tension cord (T), the tooth (E), the sprocket (S) and the top of the tooth (H). The cord is positioned in a body of the belt. The tooth projects from the body of the belt and has profile with two not equal radii connected successively and located between the top of the tooth and the base of the tooth. The sprocket has the recess (D) for reception of the tooth; also, the profile of the recess has one linear part between two not equal radii. The top of the teeth interacts with specified part of sprocket recess so, that tension cord is maintained in arc-shape between bases of teeth.

EFFECT: reduced vibration of belt at operation.
