Recommended Tolerances For Assembly - Harmonic Drive CSD-2A Component Sets Engineering Data

5.4 Recommended Tolerances for Assembly

In order for the new features of Harmonic Drive® Units to be exploited fully, it is essential that the tolerances according to
table 37.1 are observed for the input assembly.

The values in brackets are the recommended tolerances for component sets featuring a Wave Generator without Oldham coupling. The Oldham coupling
serves to compensate for eccentricity of the input shaft and is available in the standard version. For the direct mounting of a Wave Generator without Old-
ham coupling (optional) on a motor shaft, the shaft tolerances should fulfill the DIN 42955 R standard.
