: Heat-treated alloy steel gears (often 25KhGT or 40Kh) provide high resistance to contact fatigue.

In the context of Soviet and Post-Soviet engineering, a refers to a gear reducer (speed reducer) manufactured according to the State Standards (GOST) of the Russian Federation and CIS countries. These standards ensure interchangeability, durability, and specific performance metrics for industrial machinery.

: Available in multiple assembly schemes (e.g., Scheme 11, 12, 21, 22) allowing for different input/output shaft orientations.

: High mechanical efficiency ranging from 96% to 98% per stage.

: Contact lip seals or labyrinth seals to prevent lubricant leakage and protect against dust (IP54/IP55 equivalent). Common Applications

: Built strictly according to GOST 20373 for variant layouts and GOST 15150 for climatic execution (usually Category U1, U2, or T).

: Designed for both constant and variable loads, capable of operating in reverse or unidirectional modes. Key Performance Features

: Natural air cooling through a cast-iron or aluminum alloy housing with integrated cooling fins. Structural Components
