AXU Series, ES Series (World K Series) and US Series |
The
BX Series, FBL II Series, AXH Series and BHF Series
are all combination types in which the motor and
gearhead are pre-assembled. Use the mounting screws
provided to mount the device.
|
|
Use
the screws provided with the gearhead and secure
all the parts so that there are no gaps between
the motor flange face and the pilot end face of
the gearhead.

Dimensions
of Mounting Holes
The dimension of the four motor mounting holes is
shown as pitch diameter in the dimensions of each
product. The distance between the mounting holes
is shown in the table.

Method for Hollow Shaft Type Gearheads
Example of Attaching the Load
|
Attach the load according to load shaft conditions
as shown in the
figure below. The hollow shaft inside dimension is
machined to a tolerance of H8, and incorporates a
key slot for load shaft attachment. A load shaft tolerance
of h7 is recommended. The key provided with the product
should be secured to the shaft. Also, apply a lubricant
such as molybdenum disulphide grease to the load shaft
and the inner circumference of the hollow shaft. The
recommended dimensions of the load shaft are shown
in the table to the right. |

Method of Securing the Load
to an Output Shaft
|
The
output shafts of high-power gearheads are
provided with a key slot to secure the load,
while the shafts of gearheads with comparatively
low power have been given a shaft flat. Round
shaft motors come in two types, those with
and without a shaft flat on the motor output
shaft.

|
On round shaft types, the output shaft is machined
to the accuracy of H7 in dimension and 0.0008
inch or less in eccentricity. Therefore, when
connecting a load to the shaft if the device,
take measurements using a dial gauge or similar
instrument so that there is no eccentricity.
When the shaft center of two shafts does not
fit, use a flexible coupling (MCL coupling)
etc. to avoid unnecessary strain on the shaft.
The same procedure should be applied when securing
a load to gearheads. |
|
Securing
the Load to a Shaft Flat
With
a shaft flat, use a locking screw to
ensure that the lead does not slip.
We recommend using double point screws
or other screws with strong locking
power.
|

 |
| |
|
|
Securing
the Load Using a Key Slot
Secure loads using the key provided
with the gearhead after machining the
key slot on the equipment to be connected
(sprocket etc.).
Note:
Ensure that the gearhead shaft is not
subjected to shock in the axial direction,
since this will have an adverse effect
on the bearings. Be especially careful
not to us a hammer when inserting the
key. |
