FITTING OF THE RACK
The following rules must be respected by the rack fitting for the correct
functioning and endurance of the automated system:
-
The various rack pieces must be lined up correctly , one with the other.
-
In the joints the pitch of the teeth must be kept constant between one
section and the next (see the following paragraphs).
-
The height of the rack (C11 - A measurement) must be observed and
adjusted to prevent the weight of the gate falling on the geared-motor.
ATTENTION
NEVER WELD WHEN THE GEARED-MOTOR IS CONNECTED TO THE
MAINS
If the lower edge of the gate is too low to fit the rack, it is necessary to create
a base support; in fig. C 12 an example is given of a base created with a section
bar; if the plastic rack is used and the thickness of the section bar doesn’t allow
the use of self-tapping screws, use the M 6 bolts.
ATTENTION
The A measurement depends on the type of pinion and the type of rack
used (see tables in C11).
The ONDA 500 / ONDA 800 can use two types of racks:
A - Plastic rack with a steel core
B - Galvanized Steel rack
In both, the length of each piece is 1 m.
WARNING
Never lubricate or grease the rack.
