Description

Wave transmissions are known that contain flexible and rigid wheels and a generator made from rollers mounted on axles. The proposed gearing is characterized in that the rollers are mounted eccentrically with respect to the axes, are evenly distributed around the circumference and are kinematically connected with each other and with the drive shaft so that they are driven into rotation with the same angular velocity. This reduces the energetic transmission and increases its speed. FIG. 1 shows the described transmission in longitudinal section; in fig. 2 - the same cross-section B; in fig. 3, 4 and 5 - variants of the drive circuits in motion of the rollers. The transmission contains a flexible wheel 1 connected to an output shaft 2, a rigid wheel 3 connected to body 4, and a generator consisting of rollers 5 seated on eccentric necks 6 of axes 7. The axes are set evenly around the circumference in the body so that the eccentricity e of all the rollers located in the wave vertices is directed along the radius-vector of the transmission from the center of rotation; the rollers located in the trough of the wave are radially vector to the center of rotation; the eccentricity of the axes of the intermediate rollers - at an angle to the radius-vector, equal to where f; - the angle of rotation of the eccentric RELATIVE of the radius-vector in degrees; and - the number of transmission waves; n is the number of rollers; i is the sequence number of the roller from the top of the wave. On axles x 7, gears 8 are fixed, which are in engagement with a central gear wheel 9 connecting the gears 8 to each other. One of the axes 7 serves as an input shaft 10. Rotation from the input shaft through gears 8 and 9 is transmitted to all axes 7, acting on the flexible wheel 1 through the rollers 5, which communicate its walls with a wave sinusoidal motion and engage it with a rigid wheel. 3. Thus, in one revolution of the input shaft 10, all axes 7 are also rotated one revolution. As an input shaft, in addition to the axis 10, the axis 11 of the central gear wheel 9 can serve. In this case, the described transmission can be two-speed. The axes 7 of the rollers 5, in addition to this method, can be kinematically connected by means of a chain transmission 12 by means of sprockets 13, seated on axes 7 (Fig. 4), or directly by gear wheels 14 (Fig. 5). In the latter case, the rotation of the axes 7, and hence the rollers 5, will be multidirectional. This must be taken into account when giving the starting position to the eccentrics; the sign of the angle f; odd rollers will be positive, and even rollers will be negative.
