Recommended application field: Ship and stationary turbogear units, air, space technology and other branches of engineering.

Technical characteristic: Increase of the loading capacity with contact voltage in 2…2,6 times; Size and weight rates decrease of the reduction drives by 30…50%; Selling powers are 60.100 megawatt, circular velocity is up to 175…225 m/s; Noise reduction by 15…25 dB; The possibility to replace helical gears by spur gears if there is a “deep” tooth profile.

Advantages over analogues: The tooth gears are protected by the 10 patents for an invention and have no analogues as of today. They are characterized by a very high loading capacity, improved size and weight and vibroacoustic rates.

The development stage readiness: Pre-production model is made

Technical and economic effect: Saving rate of the one reduction gear, with power transmission of 60 megawatt having circular velocity of 150.175 m/s, is from 30 to 50 thousand US dollars.

Description of the development:
()
Tooth gears with the initial tooth point contact, toothed wheels of which are divided into two gearwheel rims and the wheels are returned in relation to the first rims in a circumferential bending to the definite angles. Similarly the third rims are returned in relation to the second rims, and the forth rims are in relation to the third ones in direction to the definite angles.
