 High
Accuracy Angular Measuring
Rack
A unique feature of helicoidal rack is
that it provides correct gear action even when mounted on a curved
rather than straight surface. Angular measuring rack
occupies a minimum of axial space allowing rotary tables to be designed
for greatest stability. Robust hardware and accurate measurement
feedback and control is assured by the use of SEL Precision Series Rack
and Pinion Systems.
Our Angular Measuring Rack (AMR) system
is supplied as a rack set to suit a specified diameter. The range
is from 570 mm upwards with close intervals between possible working
diameters. When included in an initial design concept, the AMR
gives particular benefits. The measuring radius is a large
percentage, usually from 50 to 80 percent, of the maximum working
radius, producing high repeatability.
A very practical benefit to the design
of, for instance, a rotary or indexing table is that no axial space is
needed below the table. This makes it lower and stiffer, along
with other parts of the machine, increasing machine working rates and,
again, repeatability. |
