Lighten Your Future Workload with the Ultimate Coupling.
For those
involved in the design of motion control and automation systems,
the elimination of excess mass and inertia continues to make the
difference between success and failure. Energy savings, higher
throughput rates, and reduced downtime, all without compromise to
quality or accuracy, are on
the minds of almost every machine design
engineer today. To address this requirement R+W has introduced a
revolutionary new servo torque limiter, SL Series, with half the inertia
and less than half the mass, allowing for a rapid and automatic
recovery from torque overload even in the most advanced drive
technology.
The use of mechanical torque limiters is
often considered to be outdated by those who prefer to control torque
overload through electronic current limitation. While this is effective
in many cases, as machinery becomes more dynamic, the inertia of moving
parts becomes more critical. It is indeed possible to abruptly
decelerate a rotating mass through unintentional blockage or application
of a dynamic braking system at a faster rate than the drive would
normally accelerate. This creates torque overload through reflected
inertia which is completely independent of the electronic system, and
can easily exceed the peak torque rating of the motor. While older and
bulkier designs may be out of the question, these modern mechanical
torque limiters offer a high level of sensitivity and accuracy, with
increasingly smaller impact on the size, mass, balance, and power
consumption of the drive system.
To achieve its target of 50% weight
reduction, R+W embarked on a two year collaborative effort
with local universities, designing the product from
the ground up rather than simply redesigning or optimizing existing
products. The result is a torque limiter constructed from state of the
art materials, with unique surface treatments and innovative assembly
technology - surpassing weight reduction targets and simultaneously
reducing its footprint. What that amounts to is an automatic torque
limiter with unparalleled power density on planet earth.
The SL Series, just like the previously
existing R+W torque limiter designs, has zero backlash, and can handle
in excess of 10,000 disengagement events, depending on rotational speed.
The four sizes Series 30 / 60 / 150 / 300) cover disengagement
torque values from 5Nm to 700Nm, and involve various mounting
options, including both direct and indirect drive versions.
Proving once again that there is a place
for mechanical torque limiters in cutting edge machinery design, the SL
Series gives everyone who has overlooked this type of device due to size
or weight considerations a chance for a second look. Contact R+W today
