Motorizable 1-axis guides
Belt guides
One advantage to using belts for moving linear guides is their silence
along with the possibility of achieving high speeds of up to 2-3 m/s.
CTS's belt guides use an AT10 belt of different widths
depending on the load to be moved. The steel trefoil inside prevent elongation
and elasticity phenomena while working.
The belt guides are supplied with a maximum length of
6-7 m. After this length on the belt guides there is
the problem of “sliding” of the belt on the aluminium profile
and the difficult to tension the belt
Rack guides
Rack guides are used when long work tracks have to be made. The rack
guides are also employed when all the space available must be used, and
when the carriage stands still and the guide moves. Standard rack guides
have racks with straight teeth, which are readily available on the market
should spares be needed.
Screw guides
Screw guides are used when a positioning precision of less than 0,1 mm
(worm drive screw) is required, when using very low speeds, and when the
unit has to be of compact size. In the screw guides the fitting of the
motor directly coupled to the screw facilitates the use of very low torque
motors. Screw guides are supplied with both spherical worm screws and
with trapezoidal screws, depending on needs.
Chain motorizable guides
Chain motorizable guides are used mainly for lifting or when the ambient
temperature is so high that the use of belts is ruled out.
Using chain motorizable guides overcomes the risk of skipping teeth, which
can occur when belts are used for vertical movement.
Linear actuators - reciprocators
The linear actuators shown in the figure are commonly referred to as
"reciprocators".
In the first case the two carriages move simultaneously because as one
rises and other descends (the classical application is that of a counterweight
to balance the exertion of the motor). In the second, the two carriages
move away from each other and towards one another simultaneously (useful
for creating a pick-up system, door opening system, compactor, etc.).
