Reference designation of reducer by order:

Reducer ВКУ - 765 - 90 - 23 - У3, where:

ВКУ - type of reducer;
765 - total distance between axes, mm;
90 - reduction ratio;
23 - assembly configuration;
У3 - climatic version and category of placing according to GOST 15150-69.

Note
Version of low-speed shaft end is cylindrical - Ц.
