igus
®
offers multi-axis robotic cable protection with triflex
®
energy chains. triflex
®
TRE chains are available in an "A"
version or a "B" version.
When triflex
®
TRE was first developed, only an "A" version, TRE.A,
was offered. The design is based on a ball-and-socket principle, with
a molded plastic ball on one side and a socket link on the other.
This link-by-link structure allows the chain to be easily lengthened
or shortened. Taking triflex
®
TRE.A apart is simple, as it just needs
to be twisted with no special tools required.
Customers began using triflex
®
TRE.A in highly dynamic robotic
applications. Since triflex
®
TRE.A chains can be twisted apart and
bent over their own radius, the links would sometimes separate during
operation and expose the cables. To solve this issue, igus
®
engineers
responded with the development of a "B" version, triflex
®
TRE.B.
triflex
®
TRE.B was developed with four times higher torsion and
bending radius strengths than TRE.A. The "B" version has the
same ball and socket connection as the "A" version, but it has been
enhanced with an additional arrester. This button-like component
serves as a defined stop-dog to prevent the ball from slipping out of
the socket and the chain from twisting apart.
Since triflex TRE.B is more secure, an L key wrench is required to disassemble the chain. To take the chain apart,
the link is turned on one side, the tool is inserted to create a ramp-like mechanism, and the edge is rolled up to
disengage the ball. To learn more about triflex
®
B assembly and disassembly, watch this video.
TRE.B is recommended for all robotic applications, including material handling, welding, vision and painting. TRE.A
is recommended for static and low duty applications with little to no torsion, such as wireways, furniture and machine
tools.
