Description

The invention relates to gear planetary gears with driven sun gear and driving planetary gears that are meshed with their enclosing gear, which is rotated at various angular speeds from the drive shaft. In the proposed transmission, the surrounding gear is rotated through a series of gears, of which the latter is coupled to the inner rim of the fixed casing, and the intermediate gears rotate freely on the rollers supported by the washer, which is mounted on the drive shaft and carries the planetary gear.

In FIG. 1 shows a longitudinal section through the GH transmission of FIG. 2; FIG. 2 and 3 are cross-sections in AB and CD in FIG. one; FIG. 4 is an EP section of FIG. 2

A washer 4 is mounted on the drive shaft of the engine, bearing the planetary gear 5; sun gear 6 is mounted on the driven shaft. Encompassing shch-. The stern 8 is coupled with a 2P gear mounted on one roller with a gear 22, which is in constant engagement with gears 23 and 25, which receive rotation through friction cones 24.24 from gears 15,15 special with the inner crown of the fixed casing 7 .

The ratio of the revolutions of the driving and driven shafts is varied by means of the enclosing gear 8 and the braking device 9-W-11-12 - 13-14.

When the brake lever 14 is in the extreme position, the speed of the sun gear (. (Where the rotation speed of the drive shaft and the washer 4) is obtained.

In position II incomplete braking, the speed is higher than the first

if lever 19 is on, and

included lever 30.

If lever 14 is in position III and levers 19 and 30 are also turned off, that movement will not be transmitted. But it is enough to turn on one of the levers 19 or 30 or brake 14 in order to get the appropriate speed.

The subject matter of the invention.

1. Planetary gear transmission with driven sun gear, driving planetary gears and gears, enclosing planetary gears and driven into rotation at various angular speeds from the drive shaft, characterized in that the driving gear of the enclosing gear 8 rotates (Fig. 1.3 )
