DESIGN LIMITATIONS FOR MULTI SPINDLES AND WHEEL MULTI SPINDLES
Three design equations are to comply with:
l < d x A/C + B
l < d x D/C + E *
l < d x (k1 x C + k2 + k3/C)/1000 + K *
*: equations applicable only when all the constants are set to values in the table below.
where:
l
mm Total shaft + socket length mesasured fully extended from the front bearing to socket tip
d
mm Pattern diameter on wheel multis or minimum distance between spindle shafts
C
Nm Tightening torque
A, B ,D and E Constants depending on module size (refer to the table below)
k1, k2, k3
Constants depending on module size (refer to the table below)
and K
Overall recommendations:
● Make sure that the screw is quality class 12.9 and that the correct torque are applied (Refer to
Figure A page 13).
● If the application requires a longer shaft length "l" than calculated with the equations, it is advised to
select a greater size of square drive.
Output shafts of modules 6153970175 (3/4") and 6153970145 (1/2") have a common design
and can be swapped.
