Description

one

This invention relates to mechanical engineering, in particular to non-Easstatic gears with elastic deformation of a ring gear.

The purpose of the invention is to reduce the dimensions of the flexible wheel.

FIG. 1 shows a flexible outer gear with an engaged gear; in fig. 2 shows section A-A in FIG. 1 | in fig. 3 — flexible internal gear wheel with gear; in fig. 4 shows a section BB in FIG. 3

The flexible wheel for backlash-free engagement consists of a cylindrical part 1 with a ring gear 2, a bottom part 3, and a hub 4. On the cylindrical part 1 adjacent to the bottom part 3 there are through holes 5, evenly spaced around the circumference. At the bottom 3, uniformly spaced through windows 6 are formed in the form of sectors shifted by half a step relative to windows 5. A jumper 7 connects the cylindrical part 1 to the bottom 3. Thus, windows 5 and 6 form a row of beams 8 on the cylindrical part and p d beams 9 at the place of transition

4acTji 1 to bottom 3. Flexible wheel meshed with gear 10.

5 A flexible wheel for backlash-free engagement operates as follows.

When the flexible wheel operates, its cylindrical part 1 is deformed by the action of gear 10.

 О In the presence of a sponge ring and other manufacturing inaccuracies, the magnitude of this strain will fluctuate. As a result of the deformation, an expansion effort occurs. R.

 5, the beam 8 will bend, and window 5 allows this deflection to be performed. At e from. . force P will deflect beam 9, and windows 6 allow this

20 deflection At point d, the beams 8 and 9 will be progressed simultaneously. The windows in the bottom part give the wheel suppleness in the circumferential direction, which allows damping the oscillations of the transmitted torque.

Thus, the flexible wheel for backlash-free engagement has sufficient radial and circumferential compliance, low weight and overall dimensions.

Claims (2)

1. A FLEXIBLE WHEEL FOR NON-CLEARING CONNECTION, containing a crown and a hub, and at least two rows of windows displaced by half a step are formed on the wheel, forming at least two rows of elastic beams, characterized in that, in order to reduce the dimensions, it is made in the form glass, the bottom of which is a hub, one row of windows is placed on the cylindrical part, which is the crown, and the other on the bottom so that the row of beams formed by them is placed at the transition point of the cylindrical part to the bottom. 2. A wheel according to claim ^, characterized in that the beam carrying the crown and the row of beams enclosed between the rows of windows are made of equal rigidity. Fig. /
