SU89256A1 - Planetary inertial gear with automatic gear ratio change - Google Patents

Description

The known plane-inertial gears with automatic change of the gear ratio have loads mounted movably in the radial direction on the axles of the satellites. These loads move in circles located eccentrically on the satellites' axes. Such an implementation of these gears leads to significant friction losses and a great deal of wear on these guides, but with which the weights move.

The proposed inertial planetary gear eliminates this disadvantage in that the supports of the loads, which interact with the guide tracks, are made in the form of balls installed in the holes of the loads.

FIG. 1 shows a section of the transmission but the plane LL; in fig. 2 shows a section along the plane BB and FIG. one.

The master drove / carries the satellites 2, through the axes of which radially passes the guide rods 5gruz-.

At the ends of the weights there are holes, in which balls 5 are laid, interacting with the carrier tracks of the carrier. The sun wheel 6 is rigidly mounted on the driven shaft.

When the satellites rotate around their axes, the loads, guided by balls and guide tracks, move in circles that are eccentric relative to the axes of the satellites. The resultant of these forces is added to the resultant centrifugal forces developed by the loads when the carrier rotates around the cBoeJi axis. The resultant force resulting from the addition of two equinoxes does not pass through the axis of rotation of the satellite, and therefore the satellite is influenced by the torque that is transmitted to the solar wheel.

When the carrier and the stationary sun wheel rotating at a given speed, the satellites rotate at maximum speed and the loads develop the greatest centrifugal forces, which entails maximum torque on the satellites and the solar 01M wheel.

As the speed of rotation of the sun wheel increases, i.e., as the gear ratio decreases, the speed of rotation of the satellites decreases, and with it the torques on the satellites and the sun wheel decrease.

Predmrt invention

The planetary inertial transmission with automatic change of the transmission ratio, comprising satellites and inertial loads rotating around the axes of the satellites along the guide tracks eccentric relative to these axes and developing centrifugal forces that create torques and satellites and the driven solar wheel, differing from In order to reduce losses and friction and wear of the guides, balls were used as supports for loads interacting with guide tracks.
