Speed reducers stand up to shocking
duties
New speed reducers employ a unique, proven principle, which distributes the load over many contact points, allowing them to withstand intermittent shock loads of 500% of the rated capacity.
Sumitomo's new 6000 Series Cyclo speed reducers employ a unique, proven principle, which distributes the load over many contact points, allowing them to withstand intermittent shock loads of 500% of the rated capacity In addition, the Cyclo 6000 Series has increased torque capacity, by as much as 12% compared with previous models, meaning that, in some applications, users are able to downsize, and benefit from significant cost savings

Drives promise finer control
Fine Cyclo drives combine all the high shock overload characteristics and reliability of standard Cyclo units in a compact package designed for precision applications.
Sumitomo's Cyclo 6000 is unsurpassed by any other inline drive available in the market today, an assertion backed-up by the fact that the Cyclo 6000 is the only reducer or gear motor offering 500% momentary peak loadings.
This means that the units are ideal for severe, high-shock applications, where they offer high efficiency, even at high reduction ratios.
In addition, as all Cyclo units offer almost frictionless operation, which all but eliminates conventional limitations due to heat, wear and tear is insignificant, and maintenance is minimal.

Gearboxes help move mountains
The conveyor belt linking MQP's Old Cliffe Hill and New Cliffe quarries in Leicestershire is powered by specially manufactured drive packages including high strength Paramax gearboxes.
The key to Cyclo performance is a unique Cycloidal design, which offers advantages in a number of areas compared with speed reducers using common involute tooth gears.
First, in the Cyclo 6000 design, all torque- transmitting components roll easily, and are symmetrically placed around shafts for perfectly balanced, smooth, vibration-free and quiet operation.
Secondly, because these components operate in compression, not in shear, they cannot shear off like traditional gear teeth.
Thirdly, unlike gear teeth with limited contact points, a 6000 Cyclo unit has two thirds of its reduction components in contact at all times.
These components - unique Cycloid discs - provide a smooth progressive rolling action that eliminates friction and the pressure points of conventional gears.
Fourth, as the drive shaft and the eccentric cam of the Cyclo units are the only components to rotate at high speed, the overall moment of inertia is unusually low.
This means that the Cyclo is ideally suited to frequent start-stopping-reversing duties, and for combination with frequency inverters.
Not only do Cyclo speed-reducers offer higher performance than other type of gearboxes in the same transmission class, they are also smaller and lighter and offer higher overall economy.
Reduction rations from 6:1 to 119:1 are available in just one stage, meaning that 3-step gearboxes offer potential transmission ratios of almost 1,000 000: 1.
Underlining the fact that Cyclo units offer exceptional life - tests on the speed-reducers show negligible wear after 50,000 hours of operation - they are all supplied with a factory-backed 24-month warranty.
