The disadvantage is the complexity of the design.

All these designs have a large number of high-precision parts that Assembly ensure the efficiency of the gearbox. Also provided by the invention is the improvement of operational properties of the gearbox by reducing the number of parts, affecting the efficiency of the transmission.

This objective is achieved in that the crown through the swivel bearing is installed on the pins of the led, and its position is fixed relative to the housing through a fixed finger with the installed rusk on samoustraniajutsia the bearing, with the Central gear mounted on samoustraniajutsia the bearing in the bore of the trunnion drove.

The layout of the gearbox is a single unit mounted directly on the shaft of the working machine. In the proposed design:

1) there is no need for high-precision housing (replaces the protective cover), because the Central wheel with the internal tooth (crown) is mounted on a spherical bearing directly on the axle carrier. Fixing the position of the crown through rusk, mounted on the fixed finger through the self-aligning bearing;

2) the combination of the mobility of the crown and satellites on spherical bearings eliminates the joints of manufacture errors (eccentric ring at the Maag on the axes of the satellites and rings of elastic at the crown of Ranka);

3) lubrication system allows g is OSU fixed swivel, mounted on the trunnion with the minimum (zero) clearance with the freedom of self in relation to the casing through a flexible macropodum. Fixing the position of the swivel is provided by rusk mounted on the fixed finger through a self-aligning bearing.

The drawing shows the gearbox.

The gearbox has a carrier 1 with 2 satellites that are installed on double row spherical roller bearings 3, the Central gear 4 on double row spherical roller bearing 5 located in the bore of the trunnion 6 of the carrier 1 through the glass 7, the crown 8 installed via double row spherical roller bearing 9 on the axle 10 of the carrier 1.

Stop crown is carried out by rusk 11, mounted on the fixed finger 12 through a swivel bearing 13.

A supply of lubricant is carried on the swivel 14, fixed by nuts 15, mounted on the fixed finger 16 through the swivel bearing 17 through a flexible macropodid 18.

The casing 19 protects gear from the influence of the external environment.

The transmission of torque from the Central gear 4 is mounted on a spherical bearing 5 in the trunnion 6 of the carrier 1 through the second bearing 9. While fixing the position of the crown 8 is carried out by rusk 11 mounted on the fixed finger 12 through a swivel bearing 13.

Lubricant for the gearing and bearings satellites 2 is fed to the rotating carrier 1 through the casing 19, a flexible macropodid 18 and the fixed swivel 14.

The stillness of the swivel 14 is provided by rusk 11 mounted on the fixed finger 12 through a swivel bearing 13.

The use of the proposed solution allows to improve the performance properties of the gearbox, to simplify its design.

The invention created in the performance of their job.

Reducer containing drove with Zapf, satellites, center pinion, crown, bearings, housing, characterized in that the crown through the self-aligning bearing mounted on the axle carrier, and its position is fixed relative to the housing through a fixed finger not installed it by rusk on samoustraniajutsia the bearing, with the Central gear mounted on samoustraniajutsia the bearing in the bore of the axle carrier.
