Abstract

The invention relates to friction converters of motion and may find application in devices where the conversion of an oscillatory motion into a rotational motion is required. The purpose of the invention is to increase the power of the device by uniformly distributing the forces of the normal pressure over the area of the frictional interaction between the driving and driven members. The mechanical oscillations of the generator 2 are converted into a reciprocating rotational movement of the disk 5. During its forward movement, the angle between the rods 8 and the ends of the disks 5,6 increases to a limit value of 90. Since the disk 5 does not have axial movement, the rods 8 press the disk 6 to the disk 4, which make a joint rotation at a certain angle. During the reverse movement of disk 5, disk 6 is wedged by disk 4, which by inertia rotates in the same direction, and disk 6 together with disk 5 rotates to its original position, after which the cycle repeats. The spring 10 maintains an unchanged distance between the disks 5.6 and the angle of., And also ensures the initial compression of the disks 4 and 6. I 3.p. f-ly, 1 ill. s cl

Description

Xi

The invention relates to the mapping, in particular to frictional motion converters, and will find application in devices that require the conversion of an oscillatory movement into a rotational one.

The purpose of the invention is to increase the power of the device due to the uniform distribution of normal pressure forces over the area of frictional interaction between the driving and driven members

The drawing shows the structural diagram of the device

The device contains a base 1, a generator 2 of mechanical oscillation 1, a rod 3, one end rigidly connected to the base 1, a driven rotary disk 4 and a driving link in the form of two coaxial and parallel disks 5 and 6, the first of which interacts with the generator 2 , and the second frictionally interacts with the driven disc 4. The discs 5 and 6 are connected by spherical hinges 7 with at least two rigid rods 8, which are mounted to the ends of the discs 5 and 6 at an indirect angle with. „

The disks 5 and 6 are mounted on the free end of the rod 3 for rotation, and the disk 6, in addition, has the possibility of axial movement. In order to make it possible to equalize the normal pressure forces from the disks 5 and 6 to the disk 4, the disk 6 is installed on the rod 3 s. using spherical iKoro bearing 9. Between the disks 5 and 6 on the rod 3 is installed a spring 10, the compression force of which is regulated, for example, by a nut P. The spring 10 serves to adjust the pressing of the disk 6 to the disk 4 o

The device works as follows

MECH; the anic oscillations developed by generator 2 are converted into reciprocating rotational movement of disk 5. During its forward movement, the angle d between the rods 8 and the ends 5 and 6 increases to a maximum value of 90 °. Since the disk 5 does not have an axial movement, the rods 8 tend to move the disk 6 towards the driven disk 4 and press them together with great force. As a result, if the distance between the disks 5 and 6 remains unchanged, there is a jamming

disks 4 and 6, and they make a joint turn at some angle. The direction of rotation depends on the direction of the angle of inclination of the rods 8 to the ends 5 and 6,

During the reverse movement of the disk 5, the angle between the rods 8 and the ends of the disks 5 and 6 tends to return to the original, as a result of which the friction forces between the disks 4 and 6 are reduced, and the disks 4 and 6 wedge. The disk 4 continues to rotate in the same direction by inertia, and the disk 6 together with the disk 5 makes a reverse rotation to its original position. This is facilitated by the spring 10, which does not allow the disk 6 to approach the disk 5 while maintaining the final angular position, but keeps the distance between the disks 5 and 6 and, consequently, the angle constant.

Subsequently, the cycle of interaction between the disks 4-6 is repeated. By selecting the values of the masses of the disks and the frequency of oscillations, it is possible to ensure almost uniform rotation of the driven disk 4. The uniformity of the forces of normal pressure is ensured by automatically turning the disk 5 on the spherical bearing 9 in the right direction and to the desired angle.
