SIMOLOC assembly system
The new SIMOLOC assembly system has been designed to pro-
vide a friction-locked connection between the motor shaft made
of drawn shaft material of grade h11 or lower and the hollow
shaft in the gearbox.
The SIMOLOC assembly system offers a low-cost, easy-to-fit al-
ternative to conventional shaft connections such as hollow shaft
with a feather key, hollow shaft with shrink disk or hollow shaft
with spline.
It is compatible with the shaft-mounted designs of the parallel
shaft, bevel and helical worm gearboxes.
Several diameters are available for each gearbox size.

Benefits
Cost reduction
•
The drive shaft of the motor can be made of low-cost, drawn
shaft material of grade h11 or lower.
•
The shaft is cheaper to machine because there is no need to
machine the shaft seat and a keyway is not required.
Quick and easy mounting
•
Easy to mount and dismantle thanks to adequate clearance
between the motor shaft and hollow shaft. The press fit is not
made until the taper bushing is inserted.
•
The press fit prevents the formation of fretting corrosion.
The taper bushing can be removed easily in order to separate
the press-fit connection.
•
No tight fits need to be overcome when the gearbox is pushed
onto the motor shaft.
Variability
•
Quick adjustment of the gearbox to different motor shaft diam-
eters is possible by replacement of the taper and bronze
bushings.
•
Easy conversion from metric to inch dimensions and vice
versa.
Available diameters
The SIMOLOC assembly system can be supplied for
shaft-mounted designs. 2 metric versions and 2 to 4 inch
versions are available for all sizes.
Scope of supply
The gearbox is shipped with a SIMOLOC hollow shaft. The diam-
eter-specific components are supplied as a separate assembly
kit. The unit is supplied with pre-assembled rotating protection
cover. The non-rotating protection cover can be ordered as an
option.
