4.Connection
4.1 When using it as a solid shaft
(1)
To properly connect the Geared Motor to the machine, reduce the
eccentricity between the motor and machine to 0.05mm or less.
Use the flexible coupling to easily connect the motor to the
machine.
(2) Adjust deflection amount of the chain to 4% of the span(refer to
Fig.1). If the deflection amount is too large, a great shock may
be applied at starting, and the geared motor may be damaged by
the shock.
(3) To prevent damage caused by the overhang load, adjust the
positions of the sprocket, gear, pulley, etc. so that the loading
position can be closer to the joint of the output shaft and the gear
case (refer to Fig. 2).
(4) The tolerance for the holes of the sprocket, coupling, etc.
should be H8. Smoothly install the sprocket, coupling etc. using
the tap on the output shaft (refer to Fig. 3).
(5) Do not use any hammer for installation. Application of a large
force may damage the bearing, gear, etc.
4.2 For hollow shaft
Prepare the parts shown in Fig. 4 to easily connect the motor. We cannot supply any tools necessary for attachment or removal. Please prepare these
tools by yourself.
Attach an attached protective cover in an opposite drive side.（Insert striking lightly into the slot processed on the case flange face.）

If the shafts are too tight to be engaged each other, tap the hollow shaft
(output shaft) with a shock-less hammer. If you use the jigs and tools shown
in the figure, you can connect the shafts more easily.

tolerance grade. For general engagement, the tolerance of h7 is recommended
for the driven shaft. If a large shock or a large radial load is to be applied to
the shafts, tightly engage the shafts.

If you manufacture the tools shown in the
figure, the shaft can be smoothly removed.
