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

FIELD: machine industry.

SUBSTANCE: invention relates to mechanical engineering and can be used in gear transmission lubricated magnetic particle method. Gear transmission comprises timing gears, mounted on shafts, installed in a closed housing with magneto-active powdered greasing substance, activated by a externally located magnetic field source. made of diamagnetic material, teeth of timing gears are made from ferromagnetic material. Body of each timing gears is made of a diamagnetic material. In the body of each timing gears, coannular tubular element is fixed, made of ferromagnetic material. Outer diameter of the element is smaller, then the diameter of the bases’ girth of the timing gears. Width of the element is less than the thickness of the body. Element is made at the same time with the teeth of the annular gear and is connected to them by radially oriented connectors, made of ferromagnetic material. Each tooth is connected to the element by one connector, located on the side of the working side of this tooth. Cross section of each connector is the same across its entire height. Width of the connectors is equal to the width of the element, and the thickness of the connectors is set from the condition of ensuring optimum resistance to the magnetic flux, created by the source of the magnetic field.

EFFECT: providing higher quality of lubrication process of gear transmission.
