Gear unit dimensions in reduced-backlash designs
The reduced backlash design is possible for the following gear units:
- Helical gear units (R) of gear unit sizes 37 to 167
- Parallel-shaft helical gear units (F) of gear unit sizes 37 to 157
- Helical-bevel gear units (only K..7) of gear unit sizes 37 to 187
With the exception of reduced backlash parallel-shaft helical gear units FH.87 and FH.97, the dimensions of low-backlash gear units are identical with the dimensions of the standard designs.
The following figure shows the deviating dimensions of the reduced backlash gear units FH.87 and FH.97:
Type | Dimensions in mm | ||||||||
|---|---|---|---|---|---|---|---|---|---|
D6 | D7 | G4 | M4 | M5 | M6 | M7 | O1 | O8 | |
FH.87/R | Ø 65 h6 | Ø 85 | Ø 163 | 41 | 40 | 46 | 45 | 312.5 | 299.5 |
FH.97/R | Ø 75 h6 | Ø 95 | Ø 184 | 55 | 50 | 60 | 55 | 382.5 | 367 |
