Cautions/prohibitions
Cautions/prohibitions
- 1. Using the same material for screw gears may cause wear and galling, so the combination with other materials is recommendable.
- 2. The allowable torque shown above is a reference value calculated under arbitrary usage conditions. Please check the precautions for details.
- 3. The backlash shown above is the normal backlash when assembled with the same part number at theoretical value.
- 4. When using for skewed shafts (screw gears), it becomes a combination of helices in the identical direction (right and right or left and left), and when using for parallel shafts (helical gears), it becomes a combination of different helices (right and left).
- 5. The tolerance of ø4 or less hole diameter (diameter 4 mm) is H8. Also, if the hole diameter is ø5 (diameter 5 mm) or ø6 (diameter 6 mm) and the hole length (overall length) is more that 3 times the hole diameter, the tolerance is H8 as well.
Precautions for alteration
- 1. For alteration to screw gears, it is necessary to check "precautions for alteration" in the precautions for safety before alteration.
- 2. Please refrain from processing to narrow the tooth width because it will affect the accuracy and strength of the gear.
