The mechanical accuracies of the output shaft and mounting flange are shown below for the KDU
Series motor:
unit: mm
Accuracy items KDU-13
1. Output shaft surface runout 0.002
2. Deflection of output shaft 0.040
3. Parallelism between the output shaft
end mounted surface
0.040
Note: All values are T.I.R. (Total Indicator Reading).
The measuring for the values are as follows:
(1) Output shaft surface runout
The dial gauge on the fixed part measures the axial
runout (maximum runout width) of the outermost
periphery of output shaft of the output rotary unit per
revolution.
(2) Output shaft surface runout
The dial gauge on the fixed part measures the radial
runout (maximum runout width) of output shaft of the
output rotary unit per revolution.
Reducing deflection of the output shaft
The specified deflection of output shaft value of 0.040 mm is due to the assembly error of the KDU
parts.
The method for reducing deflection of the output shaft is shown below.
1 When producing the mounted load (disk) at your
company, produce it with circularity of 1 µm or less.
2 Temporarily mount the load on the KDU output shaft.
3 Set the dial gauge on the side of the mounted load as
in (2).
4 While rotating the motor at low speed, adjust the
deflection of the mounted load to lower the reading
on the dial gauge.
5 After adjusting the deflection, tighten further to secure
the mounted load.
The operations above can secure shaft deflection accuracy of 4 µm or less.
(3) Parallelism between the output shaft and mounted surface
The dial gauge installed on the output rotary unit measures the axial runout (maximum runout width) of
the outermost periphery of the mounting surface (both on the output shaft side and opposite side) of
the output rotary unit per revolution.
