The code marking of cylindrical worm reducers of the SWHF series contains all necessary data for exact identification of a reducer or a motor reducer. It is divided into two groups: the first concerns reducers SWHF, and the second - motor reducers SWHF.
Code marking of a reducer SWHF - will be used when ordering a cylindrical-worm reducer SWHF.
Code marking of a motor reducer SWHF -will be used when ordering a cylindrical-worm motor reducer SWHF.
The mounting position of the SWHF cylindrical-worm reducer is important for the correct execution of the order. The design of cylindrical-worm SWHF reducers allows to install them in various positions depending on mechanical needs of the device. All cylindrical-worm reducers delivered to the customer are filled with oil in accordance with the mounting position specified in the order. Before installing the SWHF engine in a position other than the one specified in the order, check the need for oil in the gear unit in accordance with the operating instructions or the operating and maintenance documentation (DTR documentation).
If the customer has not specified the required mounting position in the order for the motor reducer or cylindrical-worm reducer SWHF, this is the default mounting position M1 (B3) and the cylindrical reducer is filled with oil corresponding to the specified position.
Permissible mounting positions for SWHF series cylindrical worm motor reducers
Cylindrical-worm reducers SWHF are designed in such a way that the widest possible transmission range is available in a compact housing. Depending on the engine power and its mechanical dimensions (IEC housing), a cylindrical worm reducer SWHF and gear ratio can be selected. Permissible configurations of the electric motor with the SWHF reducer are given in tables below.
Valid configurations for SWHF series cylindrical motor reducer
Cylindrical worm reducers of the SWHF series are a modern design that combines the technical features of the worm reducer SHF with a two-stage cylindrical educer WAHF. Combining these two designs in one compact housing, you get reducers with a very high gear ratio - similar to double worm reducers SHF, but with much greater efficiency. Below is a table of efficiency of cylindrical-worm reducers SWHF.
