Description

 The invention relates to mechanical engineering and can be used to create torsional vibrations of various actuators.

The aim of the invention is to expand the kinematic capabilities of the mechanism for converting rotational motion.

The positive effect is achieved due to the provision of two coaxial opposing rotational-oscillatory movements.

The drawing shows a diagram of the mechanism.

The mechanism dp converting rotational motion into rotational-oscillatory comprises body 1, two kinematically interconnected with each other with the possibility of opposite rotation of the leading shaft 2 and 3 (the kinematic connection is ensured by the engagement of gear wheels 4-8).

The shafts 2 and 3 are coaxial and at their ends facing each other, the main gear sectors 9 and 10 and the additional gear sectors 11 and 12 are cantilevered. Sectors 9 and 12 are diametrically opposed to sectors 11 and 10, with sectors 11 and 12 displaced along the axis of the shafts 2 and 3. Regarding sectors 9 and 10 in opposite directions by an amount greater than the width of the latter. The housing 1 is installed parallel to the drive shafts 2 and 3, an intermediate shaft 13 and two coaxially driven shafts 14 and 15. A main driven wheel 16 is mounted to the intermediate shaft 13 for alternating engagement with sectors 9 and 10 of the driving shafts 2 and 3 and an additional driven wheel . The latter is made in the form of a hub 17 and two toothed disks 18 and 19 fixed on its opposite ends for interaction with corresponding additional sectors 1 and 12. The main driven wheel 16 is mounted on the hub 17 an additional driven wheel 16 between the disks 18 and 19 with the possibility of relative to (). The driven shafts 14 and 15 are kinematically coupled to the corresponding SEWING driven wheels 18 and 16 by means of gear wheels 20 and 21.

The mechanics works as follows.

The drive shafts 2 and 3 rotate synchronously in different directions due to the kinematic connection from wheels 4 to 8. Gear sectors 9 and 10 alternate with the driven wheel 16, and sectors 11 and 12 alternate with the disks 18 and 19 of the additional driven wheel. At the same time, the wheel 16 and the disks 18 and 19 make an opposite rotational-oscillatory movement. The engagement with the respective wheels 21 and 20, this movement is transmitted to the two driven shafts 14 and 15.

The oscillation amplitude of the shafts 14 and 15 is determined by the gear ratio

gear wheels 16 and 21.
