Ross Flex Tester For Testing Lab Workshop.
Ross Flex Tester -
The ability of rubber vulcanizates to resist crack growth of a pierced
specimen when subjected to repeated bending can be evaluated with the
help of a Ross Flex Tester.
The Ross Flex Tester
consists of an arrangement to hold one end of the test specimens in an
oscillating grip such that they can be bent through an angle of 90° at
the specified frequency, and adjustable guide rollers to keep the free
end of the test specimens pressed down during the bending operations.
The
specimen grip has provision for holding six pairs of test specimens at a
time. The grip is pivoted on two ball bearings to give a smooth
low-friction movement. Movement of the grip causes test specimens to
bend over a silver steel ground rod with its axis coinciding with the
axis of movement of the grip. The movement is provided by a motor and
V-belts through an eccentric and link mechanism. An electronic digital
counter with backup memory is provided to record the total numbers of
bending cycles.
