• If an O-ring (I) was used for sealing in step 5 above, fix the shaft installation component to the
Step 6
reduction gear using the hexagon socket head cap screw and high-torque seal washer.
• If a liquid sealant was used for sealing in step 5 above, fix the shaft installation component to the
reduction gear using the hexagon socket head cap screw and serrated lock washers for the hexagon
socket head cap screw.
• Be sure to tighten the hexagon socket head cap screw with the specified tightening torque.
(Reference: “4.2.3. Reduction gear mounting bolts”, “4.2.4. Serrated lock washer for hexagon socket
head cap screw”, and “5.1. Bolt tightening torque”)
Note: For the bolt-clamping output shaft type, this is the end of the procedure.
If the hexagon socket head cap screw is not tightened with the specified torque, the reduction gear
does not deliver the designed performance. In addition, it could cause injury and damage to the
customer’s device and the reduction gear.
• For the pin/bolt clamping output shaft type, drill both a pin pilot hole for the reduction gear and a
Step 7
hole on the shaft installation component simultaneously using a reamer. Then, seal the reduction
gear and the shaft installation component using a liquid sealant or O-ring (I), and tap the taper pin
according to step 5.
• When drilling holes using a reamer, masking is necessary so that cutting chips will not enter the
reduction gear.
• Using the hexagon socket head cap screw and serrated lock washer for the hexagon socket head cap
screw, fix the shaft installation component to the reduction gear. Be sure to tighten the hexagon
socket head cap screw with the specified tightening torque.
(Reference: “4.2.3. Reduction gear mounting bolts”, “4.2.4. Serrated lock washer for hexagon
socket head cap screw”, “4.2.9. Taper pin with screw”, and “5.1. Bolt tightening torque”)
Note: The procedure varies only for model RV-80E. For this model, see steps 8 to 11.
