GEAR TRANSMISSION Russian patent published in 2018 - IPC F16H57/04 

FIELD: engineering.

SUBSTANCE: invention relates to machine building and can be used in tooth gears. Gear train comprises paired gears on the shafts, installed in a closed housing with magneto-active powdered greasing substance, activated by a externally located magnetic field source. Body is made of diamagnetic material, teeth of paired gears are made from ferromagnetic material. Body of each timing gear is made of diamagnetic material. In the body of each timing gear, a coannular tubular element is fixed, it is made of ferromagnetic material. Outer diameter of the element is smaller than the diameter of the bases’ girth of the timing gear. Width of the element is less than the thickness of the body. Element is made as one with the teeth of the ring gear and is connected to them by radially oriented bridges, made from ferromagnetic material as well. Each tooth is connected to the element by a pair of jumpers made as one with the element and the tooth, located at a distance from each other on the side of the tooth's lateral surfaces, with an adherence to them. Width of the jumpers is equal to the width of the tubular element. Thickness of the jumpers is directly proportional to the magnitude of the magnetic flux, passing through them. And the volume between the bridges is filled with the diamagnetic material of the wheel body.

EFFECT: optimization of the design and a reduction in the costs of manufacturing gears is achieved.
