PROCEDURE FOR COGGED BELT TENSION Russian patent published in 2011 - IPC F16H7/08 F16H7/12 

FIELD: machine building.

SUBSTANCE: tension of cogged belt is maintained with idlers in assembly with bearings secured on arms of pivoted lever and facilitating rotation. The pivoted lever is set on a bearing axle and is fixed in a specified position. Simultaneously, the idlers support tension of the belt and periodically press on the belt, when a key rotates a multi-armed lever around a bearing axle. The idlers control tension of the belt on all sections between working pulleys. Also, number of the rollers and arms of the pivoted lever corresponds to number of sections of the belt between pulleys. Kinematic and geometrical calculations of the pivoted lever in assembly with the idlers ensure control of belt tension on all sections between pulleys in direct proportion to elongations formed on these sections during operation and simultaneously the lever with the idlers function as bearing, directing and stabilising devices.

EFFECT: expanded functionality of procedures of tension of cogged belt, maintaining synchronous operation of working pulleys at regulation of tension of endless flexible element in cogged belts during operation under conditions, when between-axle space between working pulleys is constant.
