DESIGN LIMITATIONS FOR MULTI SPINDLES AND WHEEL MULTI SPINDLES
Three design equations 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 chart below.
where:
Total shaft + socket length mesasured fully extended from the front bearing to socket
l mm
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 chart below)
k1, k2, k3 and K Constants depending on module size (refer to the chart below)
Overall recommendations:
● Secure the screw quality class 12.9 and appropriate torque are applied (Refer to Figure A page 8).
● If the application requires a longer shaft length "l" than calculated with the equations, it is advised to
select a greater size square drive.
Output shafts of modules 6153970170 (3/4") and 6153970140(1/2") have a common design
and can be swapped.
