In the USSR, the TSN.02.020 drive was mass-produced by the Yelgavsilmash plant. A complete analog of this PGK-1 gearbox was mastered by Kovelsilmash.
TSN.02.020 reducer is intended for equipping horizontal manure collecting conveyors of the TSN type of all types (TSN.2B, TSN.3B, TSN.160) as an alternative gearbox NO. 11.12. The TSN.02.020 gearbox is also widely used in industrial concrete mixers. People call him "frog".
The peculiarity of the TSN.02.020 gearbox is the first high-speed V-belt transmission, which ensures smoother and safer operation of the manure collection conveyor.
Variations depend on the installation and connection dimensions under electric motor and the length of the output shaft of the gearbox. The extended version of the shaft is used for horizontal conveyor type TSN.160A with the upper position of the scrapers.
In Soviet times, the TSN.02.020 drive was mass-produced in Latvia on Elgavselmash plant. A complete analog of this PGK-1 gearbox was mastered by a number of other factories and in particular, Kovelsilmash. The TSN.02.020 reducer is installed in the farm to drive the TSN horizontal conveyor. Often this gearbox is assigned a part code - the upper housing cover TSN.02.102.
