(2) When the product cannot be installed with the motor flange already mounted
Perform steps 1 to 5 by taking care regarding the following precautions.
Step 1
•
Loosen the four hexagon socket head cap screws securing the motor flange, remove the motor flange
from the reduction gear, and then remove the liquid sealant.
• As the hexagon socket head cap screws will be reused when assembling, store them in a safe place.
A liquid sealant is applied to the area between the motor flange and reduction gear main unit (input
unit).
Due to the effect of the liquid sealant, it may not be possible to remove the motor flange easily only by
removing the screws. In such a case, make a cut in the bonded surface using a cutter knife, etc., while
taking care not to scratch the coating. Then, lightly tap the motor flange using a tool such as a plastic
hammer, and then remove the motor flange from the reduction gear main unit. Applying excessive
load could damage the reduction gear or motor flange.
Step 2
• With the motor flange removed,
incorporate the reduction gear into the
customer’s equipment according to steps
1 to 3 in “(1) When the product can be
installed as is”.
Step 3
• Wipe off the grease adhering to the
mounting surface of the motor flange and
the reduction gear, and then apply a
liquid sealant onto this surface.
(Reference: Table 4-4 in “4.2.4. Liquid
sealant”)
• Take extra care so that the liquid sealant
will not leak into the reduction gear.
• Take extra care so that the liquid sealant will not leak into the mounting bolt section.
• For the detailed coating procedure, follow the instructions given by the manufacturer of the sealant to
be used.
