Description

one

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

The purpose of the invention is to increase the uniformity of the transformation of motion.

Figure 1 shows the kinematic diagram of the device; Fig. 2 shows a variant of connecting the drive to the device; on fig.Z - section aa in figure 2; Fig. 4 shows an embodiment of a device with non-circular elliptical wheels.

A device for converting rotary motion into a complex motion of the output shaft, consisting of reciprocating and rotary, contains two pairs of non-circular bevel gears 1, 2 and 3, 4, between which are located in the middle are circular bevel gears 5, connected to each other by bases, a drive 6 with an input shaft 7, an intermediate gear transmission consisting of bevel wheels 8-10, an output shaft 11 mounted in the direction of / 1

2-14 housings 15. The drive 6 can be connected to the output shaft I1 by means of a spline coupling 16, allowing the shaft to reciprocate in the 5th direction by the amount S.

The device works as follows.

10 The rotation of the input shaft 7 from the drive 6 is transmitted to an intermediate gear transmission consisting of bevel wheels 8-10 and then to non-round bevel wheels 1 and 2, round bevel wheels 5 and non-round

15 left bevel wheels 3 and 4. In this case, the output shaft 11 performs a reciprocating motion by a value of 5 equal to the eccentricity

20 non-circular gears 1-4, and rotational movement with an appropriate gear ratio. If this device requires a gear ratio of 1, instead of

25 intermediate gears can use a splined coupling 16. Non-circular gears can have any curvature and eccentric jHocTb, depending on the required

3Q of the law of motion.
