SU1567833A1 - Arrangement for converting rotational to complex motion - Google Patents

Abstract

The invention relates to mechanical engineering. The purpose of the invention is to increase reliability. The rotation from the input shaft 1 is transmitted to the wheels 5 and 6, which, in contact with the rolling bearings 11 of the cross bar 10, imparts to the output shaft 2 a reciprocating motion. In addition, the rotation from the input shaft is transmitted by gear conical wheels 8 and 9 to the middle bevel gear 7, which imparts a rotational movement to the output shaft. As a result, the output shaft will perform a complex motion consisting of reciprocating and rotational motions. 1 il.

The invention relates to mechanical engineering and can be used in mechanisms where it is necessary to convert a rotational movement into a complex movement of an output shaft consisting of reciprocating and rotational movements.

The purpose of the invention is to increase the reliability of the device by simplifying its design.

The drawing shows the device, the overall appearance.

The device contains a drive (not shown), input 1 output 2 and intermediate 3 shafts located in housing 4, a mechanism to transform movements, including a pair of wheels 5 and 6 and an intermediate gear transmission consisting of an average bevel gear 7 and two associated wheels gear bevel gears 8 and 9.

On the output shaft 2, the yoke 10 is mounted so as to rotate about its axis. Roller bearings 11 are mounted at the ends of the cross beam 10, and an elastic element 12 is mounted between the crossbeam 10 and gear 7, while gear 7 is mounted on the output shaft 2 with the possibility of axial movement, for example, by means of a splined connection. Wheels 5 and 6 are made with internal cylindrical surfaces 13 and 14, respectively, for engagement with rolling bearings 11.

The wheel 5 is fixed eccentrically on the input shaft 1, and the wheel 6 with the same eccentricity on the intermediate shaft 3. The gear wheels 8 and 9 are mounted concentrically on the input 1 and intermediate shaft 3, respectively.

The device works as follows.

When the drive (not shown) is turned on, the rotation from the input shaft 1 is transmitted to wheel 5 and from it through intermediate gear train 8. 7, 9 to wheel 6 Wheels 5 and 6 at the same time rotate in opposite directions

parties. When rotated through an angle of 0–180 °, they move the yoke 10 and the output shaft 3 associated with it to the extreme upper position, while compressing the elastic element 12.

With further rotation of the wheels 5 and 6 at an angle of 180 - 360 ° of the yoke 10 with the output shaft 2 under the action of the elastic element 12 moves in the opposite direction to the extreme upper position, etc. Since the intermediate gear wheel 7 is connected to the output shaft 2 by a splined connection, the shaft 2 simultaneously with the return-translation movement also receives a rotational movement.

As a result, the output shaft 2 performs a complex motion consisting of reciprocating and rotational.
