Description

The invention relates to planetary gears for reducing the speeds of the drive shaft so as to simultaneously rotate two driven shafts with the same frequency and in different directions.
A planetary gear is known, comprising a housing, a planetary mechanism comprising a central wheel with external teeth, a central wheel with internal teeth, and a carrier with satellites. The transmission also contains a locking kinematic branch consisting of a set of simple gears and connecting the central wheels of the planetary gear. The transmission has one drive shaft connected to the central wheel with external teeth, and two driven shafts, one of which is connected to the carrier and the other to the central wheel with internal teeth.
The driven shafts rotate in different directions with the same frequency ij.
The disadvantages of this program are its complexity, large size and weight.
Closest to the proposed technical essence is a planetary gear containing
a body, first and second central wheels with external teeth, a central wheel with internal teeth, a carrier with satellite nodes, each of which consists of two interlocking wheels, one of which interacts with the first central wheel with external teeth, and the other with a second central wheel with 10 arm teeth and a central wheel with internal teeth t2j.
The disadvantage of this transfer is the impossibility of creating rotating in different directions with the same
15 frequency shafts.
The purpose of the invention is to obtain rotation of the two driven shafts in different directions with the same frequency.
This goal is achieved by

Claims (2)

  1. 20 that in a planetary gear comprising a housing, a first and second central wheels with external teeth, a central wheel with internal teeth, drove with satellite assemblies, each 25 of which consists of two coupling wheels, one of which interacts with the first central wheel 3 outer teeth, and the other with a third central wheel with outer teeth and a central wheel with internal teeth; the central wheel with internal teeth is rigidly connected to the housing; the carrier and the first central wheel with external teeth are selected slave, Noe second central wheel with outer teeth of the leading and the ratio of teeth of the central wheel with inner teeth and the first central wheel with outer teeth is two. FIG. 1 schematically shows the planetary gear; in fig. Fig. 2 shows a-A in FIG. 1. The planetary transmission contains a first 1 and a second 2 central wheels with external teeth, a carrier 3 with satellite assemblies consisting of two interlocking wheels 4 and 5, and also a central wheel with internal teeth The wheel b is fixed in the housing 7. The center wheel with 1 is selected as the lead, the carrier 3 and the central wheel 2 are selected. The ratio of the teeth of the wheels b and 2 is chosen equal to two. Transmission works as follows. When the drive wheel 1 rotates, it interacts with the wheels 4 and 5 of the satellite assemblies and the fixed wheel b, the carrier 3 and the central wheel 2 rotate. Due to the ratio of the teeth of wheel 6 and 2 equal to two, the driven shafts rotate in opposite directions with the same frequency The application of the proposed transmission allows reducing the number of links in the mechanism and its dimensions. Claims of the invention A planetary gearing comprising a housing, first and second central wheels with external teeth, a central wheel with internal teeth, drove with satellite nodes, each of which consists of two interlocking wheels, one of which interacts with the first central wheel external teeth, and the other with a second central wheel with external teeth and a central wheel with internal teeth, differing from the fact that, in order to obtain rotation of two driven Vsshov in different directions with the same frequency, The central wheel with internal teeth is rigidly connected to the housing, the carrier and the first central wheel with external teeth are selected as the driven one, the second central wheel with external teeth is the leading one, and the ratio of teeth of the central wheel with internal teeth and the first central wheel with external teeth are equal to two.
