PATENT FOR INVENTION

iYrcriTIPLICATEUR DE FORCE A LOW REDUCTION DE VUE.

SAISSI EDOUARD

The present invention is a device that allows for an increase in force with a small reduction in speed.

To achieve this result, the invention 5 provides a system for driving a train of satellites by a double row of internally toothed crown, at the same time as by a central planetary gear, these elements rotate in the same direction and mesh the satellites whose resulting force acts on the axes by producing a thrust in the same direction.

The axes of these satellites are fixed to a flange, or a satellite-carrying drum, which rotates on a central axis; this is the output of the assembly. 15 The arrangement of the elements is thus composed

The drive, which occurs via a rotating central shaft on which is fixed at the end of the shaft, on one side a transmission coupling or any other device acting on this shaft, is integral with a drive gear for the crown and

on the other hand, a toothed pinion which serves as a planetary gear, this axis which is mobile rotates on bearings or any other bushings, the seats of which are supported by flanges which are the frame of this assembly.

The crown is divided into two parts by a partition that serves as a support for it to bear against and rotate on the central axis; this rotation can be achieved by bearings or other bushings. The gear d1 drives the crown via one or more intermediate gears that transmit the rotation to the internally toothed portion of the crown on the input side of the device.

35 the second part of , : this crown transmits the rotation to the satellites which are geared to it and which on the other hand also receive the effort of the planetary gear.

The teeth of the pinions, 40 satellite gears, crowns and planetary gears can be straight-toothed, straight-module, or helical-toothed; the number of these elements can vary and they can be arranged according to the force to be obtained; several devices can be used in succession, each driving the other.

Alternatively, the input drive of the assembly can be arranged in place of the crown drive gear; in this case the crown is driven directly, the pinion 50 fixed to the drive shaft and the central shaft on which the planetary pinion is fixed receive their movement by the same gear, thus reducing the speed loss by increasing that of the planetary gear.
