Sumitomo have been producing superior gearboxes and speed reducers for the best part of a century. Their product names have even become synonymous with the type of device they represent. Here we take a closer look at a couple of the products in the Sumitomo Concentric range, specifically the Cyclo Drive which is widely regarded as one of the best speed reducers on the market.
Sumitomo Concentric CYCLO Drive
gearboxes boast high strength and reliability due to the proprietary Cyclo
mechanism. This unique Cyclo mechanism is also highly durable and provides an extended
One of the best
features of this speed reducer from the Sumitomo Concentric range is
the break-resistant teeth. In contrast to regular gear teeth, the Cyclo Drive’s
teeth are cycloidal discs which feature an especially smooth curve. The
internal gears also consist of these circular-arc teeth, producing a smooth
rolling contact that prevents tooth breakage. This obviously makes these
Sumitomo gearboxes last a long time.
There is also a
broad variation ensuring you can find the exact kind of Cyclo Drive for your
purposes. Capacities range between 0.1 and 132 kW with reduction ratios of between
2.5 and 658,503. In addition there are motors specifically for use outdoors and
others that are explosion-proof.
Most of the
Sumitomo Concentric speed reducer products are compact, with a wide range of reduction ratios in a single
reduction, starting from 2.5 up to 119. There are also double and triple
reduction types produced by simply layering the reducer mechanisms.
Sumitomo CYCLO Gearmotor with Torque Limiter
suppliers also supply an alternative version of the Cyclo Drive in the form of
the Torque Limiter model which can detect overloads instantaneously. The design
includes a high quality torque sensor which also helps protects the machinery
from catastrophic failure.
You will find
the torque limiter installed in the drive, a position that produces a more
accurate assessment of the machine’s safety level. The Cyclo Drives with Torque
Limiters are also compact with high reduction ratios and impressive operational
base is made of coiled springs or load cells and performs extremely accurately.
The mechanical torque detection mechanism also
enables a much shorter detection time, especially compared to other methods
such as thermal relays.
Concentric product also features a wide range of torque adjustment, with the
torque configuration being very wide. This allows adjustments to be made
on-site in order to match the actual torque of the equipment.
buzzer and indicator light in the motor operation circuit ensures safe
operation even when unattended. There are also double and triple safety models
