Installing the R88G-HPG
(Backlash: 3 Arcminutes max.)
Follow the instructions bellow to install the Decelerator and the Servomotor.
1
Turn the input joint and align the head of the bolt that secures the shaft with the rubber
cap.
2
Apply the sealant on the side which the Servomotor is installed. (Recommended sealant:
Loctite 515)
3
Gently insert the Servomotor into the decelerator.
Put up the decelerator vertically and slide the Servomotor into the input shaft joint while using
the motor shaft as guide not to fall over, as shown in the figures on the next page. When the
decelerator cannot be put up vertically, tighten each bolt evenly little by little to ensure that the
Servomotor is not inserted at a tilt.
4
Fix the Servomotor and the flange of the decelerator with bolts.
Bolt tightening torque (for aluminum)
5
Tighten the bolts of the input joint.
Bolt tightening torque (for duralumin)
Note Tighten the bolts to the torque indicated on the above table. The Servomotor may slip or other
problems may occur if the specified torque level is not satisfied.
The R88G-HPG11A uses two set screws for the connecting section.
6
Mount the supplied rubber cap to complete the installation.
(For the R88G-HPG11A , mount two screws with gaskets.)
