Abstract

The invention relates to mechanical engineering. In order to increase durability by reducing the stresses in the sealing partition, a device for transmitting movement through the sealing partition, comprising a housing 1, a stationary central wheel 2 with internal teeth and a drive shaft 3 mounted on the latter 4 mounted on axes 5 satellites 6 for interaction with the central wheel 2 and the sealing partition 8, equipped with rollers 7 mounted on the axles 5 satellites, the diameters of which are equal to the diameters of the initial satellite circles s 6, and the driven member 9 has a crown in the form of rollers for the same reaction through the sealing septum 8 with the rollers 7 mounted on axles. The device works as follows. The rotation of the shaft 3 and the carrier 4 causes the satellites 6 to run around the wheel 2. At the same time, the rollers 7 make a similar planetary motion, and in view of the equality of their outer diameters to the diameters of the initial circles of the satellites 6, the linear velocities of the roller points interacting with the partition 8 are zero. This prevents slipping in the contact zone, as well as the effect on the septum of stresses from the moment transmitted by the device. 2 Il.

The invention relates to mechanical engineering.

The purpose of the invention is to increase durability by reducing the stresses in the sealing partition and avoiding slipping in the contact zone between the driving and driven elements relative to the partition due to this design, which provides zero speed to the points of the surfaces interacting with the partition

Figure 1 shows the kinematic diagram of the device; in Fig „2 - the device, a general view.

The device includes a housing 1, a stationary central wheel 2 with internal teeth and a drive shaft 3 mounted on the latter drove 4 with 5 satellites 6 mounted on axles for engagement with the central wheel 2. The rollers 7 are mounted on axles 5 and fixed from rotation relative to satellite. 6 and the outer diameters of the rollers 7 are equal to the diameters of the initial circumferences of the satellites 6. The sealing partition 8 delimits two spaces. The driven member 9 has a crown in the form of the same rollers 7 for interaction through the sealing wall 8 with the rollers 7 mounted on the axles 5.

The device works as follows

When the drive shaft 3 rotates, the carrier 4 causes the satellites 6 to run around the fixed central wheel 2, while the satellites 6 perform

planetary motion is melting The same movement is made by the rollers 7 of the carrier 4, while due to the equality of their outer diameters to the diameters of the initial circles of the satellites 6, the linear velocities of the points of contact of the rollers J with the partition 8 are equal to zero. The rollers 7 in their planetary motion form traveling waves of deformation in the sealing partition 8, causing the rollers 7 of the slats to move. Sliding in the zone of contact of the rollers with the sealing partition is absent. The design of the device eliminates the possibility of tension stresses in the partition caused by working forces.
