Description

Flexible transmission transmission device,

The utility model relates to devices for tensioning prices or belts having a hydraulic drive, for example, for distribution systems of internal combustion engines.

A patented flexible transmission transmission device is known from the patent literature, comprising a pivoting bearing element with a double-sprocket guide sprocket and acting inside the flexible communication transmission circuit.

(See Certificate for Utility Model of the Russian Federation No. 15924, F16H7 / 08, 2000).

The flexible communication transmission tension device comprises a rotatable bearing element with a double-sprocket guide sprocket and acting inside the transmission transmission circuit by a flexible connection. The guide sprocket is located on the axis of the bearing with a rolling bearing and made L-shaped, and the distance between the rotation axes of the guide sprocket and the bearing is determined by the ratio, where d is the diameter of the axis of rotation of the bearing, coefficient C, 985-4-3,16, and the initial coordinates of the fulcrum are -d, and the angle a of the tangent to the platform of the support of the supporting element is 8 13 ° coefficient, 744-1.8 and ,, 05.

The technical result achieved is to increase the resource of the engine timing mechanism drive mechanism, increase the power, reduce fuel consumption, friction losses and increase the economic efficiency of the gas distribution mechanism.

The device is illustrated in the drawing, where in FIG. 1 - tension device transmission flexible connection.

FIG. 2 is a view along C in FIG. 1.

The flexible communication transmission tension device comprises a pivoting bearing member 1 with a double-sprocket guide sprocket 2 and acting inside the transmission circuit by a flexible communication. The two-sprocket sprocket 2 is located on the rolling bearing 3, the inner race of which is the axis of attachment to the bearing element 1. The non-supede element 1 is made L-shaped, the distance between the rotation axes of the guide of the two-sprocket sprocket 2 and the bearing element 1 is determined by the ratio, where d is the diameter of the axis 4 rotations of the housing, coefficient 16, and the initial coordinates of the fulcrum are -d, and the angle a

The essence of the utility model.

Description of utility model.

the tangent to the support site of the supporting element is 8 4-13 °, and the coefficients have the following values:, 744-1.8 and, 6b4-6.05.

The tensioning device acts on the least stretched section of the chain, the tension is carried out by the guide two-sprocket sprocket 2, the axis of rotation of which, together with the rotary bearing element 1 can deviate relative to the fixed axis 4.
