Abstract

The invention relates to mechanical engineering and can be used in drives of machines and devices. The purpose of the invention is to increase reliability by ensuring intact contact of the transmission wheels. During operation, a two-roller oscillator 2 waves with spring-loaded rollers 3, so the flexible wheel 1 to the hard wheel 5 rolls it around the perimeter of the hard wheel 5. The working surface of the hard wheel 5 is formed by two sections a and b with different curvature alternately twice and smoothly mated with each other. When the sections a are run in, due to the equality of their curvature to the curvature of the flexible wheel 1 in the free state, the output link remains stationary. When rounding up areas b, the curvature of which may be greater or less than the curvature (L of areas a, the output link receives rotation. 1 ill. Eo hO J

Description

The invention relates to mechanical engineering and can be used in drives of machines and devices.

The purpose of the invention is to increase reliability by ensuring continuous contact of the transmission wheels.

The drawing shows a wave friction transmission, cross section.

The transfer consists of a flexible wheel 1, a roller generator 2 waves, the rollers 3 of which are spring-loaded in the radial direction by springs 4, and a rigid wheel .5. The generator 2 waves sets the flexible wheel 1 n deformation waves, and the working surface of the rigid wheel 5 is formed k n successively. alternating-shs dyum sections a and b with different curvature. In the gear shown in the drawing, n ° 2.

The curvature of the area a is equal to the curvature of the working surface of the flexible wheel in a free state. Section b is made with a greater curvature than the area a. Section b can also be made with a lower curvature than area and. Areas a and b are smoothly conjugated with each other (the boundaries of the plot in the drawing are conventionally marked with strokes).

In the course of work, the generator 2 waves, pressing the flexible wheel 1 to the rigid wheel 5, rolls it around the entire perimeter of the rigid wheel 5. When the sections are rolled, and due to the equal diameters of the flexible wheel 1 and the rigid wheel 5, the output link remains stationary in this area. When running around areas

 fO b the output link receives the rotation.

The transfer consists of a flexible wheel 1, a roller generator 2 waves, the rollers 3 of which are spring-loaded in the radial direction by springs 4, and a rigid wheel .5. The wave generator 2 sets the flexible wheel 1 n of deformation waves, and the working surface of the rigid wheel 5 is formed k n times successively alternating hc dyum sections a and b with different curvature. In the gear shown in the drawing, n ° 2. The curvature of the area a is equal to the curvature of the working surface of the flexible wheel in a free state. Section b is made with a greater curvature than the area a. Section b can also be made with a lower curvature than area and. Sections a and b are smoothly conjugated with each other (the boundaries of the plot in the drawing are conventionally marked with strokes). 1 82 In the course of work, the generator 2 waves, pressing the flexible wheel 1 to the hard wheel 5, rolls it around the entire perimeter of the hard wheel 5. When running around the parcels a, due to the equal diameters of the flexible wheel 1 and the hard wheel 5 in this section, the output link remains stationary. When running around sections b, the output link gets rotated. The invention of the Wave Friction Transmission, comprising a flexible wheel, a roller wave generator, defining a flexible wheel and deformation waves, and a rigid wheel, whose working surface is formed k n times successively by alternating two sections with different curvature, where, 2, 3 ..., is different so that, in order to increase reliability by ensuring intact contact of the transmission wheels, the wave generator rollers are spring loaded in the radial direction, the curvature of the first section is equal to the curvature of the working surface of the flexible wheels in a free state and areas smoothly mated with each other.
