The meaning of letters and numbers in the model of the third level ZSC350-35.1-I medium hard tooth cylindrical gear reducer

In the three-stage ZSC350-35.1-I hard tooth surface cylindrical gear reducer model, "Z" represents the cylindrical gear reducer, "S" represents the three-stage transmission, and "C" represents the involute cylindrical gear reducer.

The number 350 at the end indicates that the center distance of the reducer is 350mm. The larger the number, the larger the external dimensions of the gearbox and the higher its load-bearing capacity.

35.1: Represents a transmission ratio of 35.1 for the gearbox.

I： Usually refers to assembly form or output shaft form, etc. The specific definition of "I" may vary slightly among different manufacturers, but generally speaking, it is an identification used to distinguish different installation methods, output shaft structures, or other specific design details. For example, it may indicate that the output shaft is a solid shaft, or a specific installation position or direction.

For ZSC (A) type reducers, the "A" in parentheses represents a vertical modular structure, which differs from the ordinary ZSC type in terms of installation method and structural form, and is suitable for specific installation spaces and equipment requirements.
