Description

one

The invention relates to the field of mechanical, planetary gears, serving to obtain large transfer ratios and can be used in various fields of engineering.

The purpose of the invention is to simplify the changeover of the planetary gearbox to another gear ratio.

FIG. 1 shows a planetary gearbox; general view; in fig. 2 - the scheme of interaction of its elements.

The planetary gearbox comprises a housing 1, a carrier 2 with a twin-satellite satellite 3, and two wheels 4 and 5 with internal teeth, each interacting with the corresponding rim of the satellite 3. The wheel 4 is rotatably mounted. The ring 6 is rigidly fixed in the housing 1 and has a radial slot 7. The inner surface of the ring 6 frictionally interacts with the outer cylindrical 182112

The chesky surface of the second wheel 5. In the slot 7 of the ring 6 there is a connecting rod 8, one end of which is rigidly connected to the wheel 5, and the second end - to the 5 hinge 9 with the body 1.

The gearbox works as follows.

When the carrier 2 rotates, the satellite 3 runs around the wheel 5, causing 10 it to perform a plane-parallel motion without rotation, while the wheel 4 rotates with a gear ratio determined by

where g is the number of teeth of the wheel 5; z is the number of teeth of the wheel 4. The gearbox is changed to another gear ratio by replacing the wheel 5, which simplifies and speeds up this operation.
