The gear housing and the cast iron cover are connected horizontally by two conical pins and bolts.
The rotational movement from the input shaft-gear through the gear wheel pressed on the intermediate shaft-gear, the gear wheel pressed on the second intermediate shaft-gear, and the gear wheel is transmitted to the output shaft. Shafts mounted in the gear housing on two taper roller bearings output shaft bearing, intermediate bearing, the second intermediate bearing, output shaft – bearings.

The gear engagement is involute oblique.
The bearings are adjusted by screws through pressure washers. The screws are fixed with locks.
The fixed joints are sealed with gaskets, and the output shafts are sealed by reducing the gaps between the shafts and the embedded covers.
In the upper part of the gear cover, there is a hole for filling the oil, closed with a cork. The oil is drained through a hole in the lower part of the body closed with a plug. The oil level is controlled by a plug on the top of the gearbox. Lubrication is carried out from a common oil bath: the output and intermediate stage engagement parts are dipped, and the input stage engagement parts and bearings are sprayed.
For lubrication of gearboxes, oils are used: Tap-15V, Tsp-10, IRP-150, ITP-200, ITP-300.
