In the case of topping-off or replacement, it is necessary to use the
lubricant Mark CA, supplied by Unimec.
b) Deficiency or deterioration of spindle lubrication: the user must
lubricate the spindle and the operation must be repeated, depending
of the type of work and environment, frequently so to ensure the
presence of a clean lubricant layer between the surfaces in contact
with each other. It’s raccomended to use Mark CA grease, manually
by brush or with automatic greaser supplied by Unimec in various
lubrication kits.
c) Failure due to the wear of subject components: the constituent
components subject to friction suffer the effects of wear. Bronze
parts (4 and 7) are the most vulnerable to wear and the scraped
material often settles on the worm gear and spindle (5 and 6)
altering the contact geometry. The failures of the bearings (8 and
9) cause the transmission to stop, while the wear of the gaskets (10
and 14) favors the leaks.
d) Lateral loads or misalignments: it is essential to ensure the
orthogonality between the spindle and the casing support plate and
to check the concentricity between the load and the spindle itself.
The application of more screw jacks to the load movement requires
further verification: it is necessary that the support points of the
load, (terminals for TP models and the nuts for TPR models),
be perfectly aligned, so that the load is divided evenly. If not, the
misaligned screw jacks would act as contrast or brake. In the case
