WAY OF DRIVE BELT TENSION OF CAR ENGINE GAS DISTRIBUTION MECHANISM (VARIANTS) Russian patent published in 2017 - IPC F16H7/12 

FIELD: engines and pumps.

SUBSTANCE: method of tensioning the belt drive a car engine timing belt is to transfer the tensile force from the rotational motion of the eccentric mechanism (1) and maintaining the belt in constant working order by the working of the spring (4). Eccentric gear (1) is designed as a cage roller (5) with the sleeve fixed in it (6). The sleeve (6) is arranged eccentrically on it and rotatably placed eccentric. Rotational movement of the eccentric mechanism (1) is carried out by applying a force on the tensioning lever (2), through which the working spring (4) transmits it to the cam lever (3) is rigidly mounted on the latter. The operating state is maintained by the tight belt tension lever lock (2) and urging the cam lever (3). Springing of the first embodiment is achieved by compression of the working spring (4) is carried out by reacting the roller cage (5) and eccentric with the belt and tension the second embodiment of the working spring (4) is carried out by reacting the roller cage (5) and eccentric with the belt.

EFFECT: invention improves reliability.
