Cyclo HBBFAQsHow do I select a Cyclo HBB reducer or gearmotor?Selection is based on the actual horsepower and/or torque requirements at the output shaft. TheCyclo HBB speed reducer has particularly high efficiencies over a wide range of reduction ratios, whichfrequently permits the use of reduced input power requirements (smaller HP motor) without sacrificingoutput shaft torque. The selection procedures in this catalog, will guide you in choosing the most efficient reducer for your application.What information do I need to get started in the selection process?To select the proper reducer for your application, you will need to know:· Application: type of driven machine· Hours of operation per day· Motor horsepower (HP) and speed (RPM)· Loading Conditions· Mounting PositionIf there are any special environmental factors or operation requirements, they must also be noted. Thisinformation will be important in determining the Service Factor of your application.Common ConfigurationsSingle ReductionGearmotorWhat are service factors and how are they used?In general, reducers and gearmotors are rated for specific conditions and operating requirements of theapplication by the use of AGMA-defined Service Factors. There are three AGMA load classifications forgearmotors: I, II, and III (pages 3.6 - 3.7). The Service Factors are used in the productselection process to adjust for the specific conditions and operating requirements of your application.What do I do if my application has particularly severe operating conditions?The standard ratings for Cyclo HBB are based on 10-hour daily service under conditions of uniformloads (equivalent to AGMA service factor 1.0). By following the product selection process, you willdetermine and apply the Service Factors to compensate for severe operating conditions.Single Reduction Reducer withC-Face AdapterHow can I be sure that the reducer can withstand periodic excessive overloads?Cyclo HBB speed reducers provide 300% momentary intermittent shock loads capacity.For applications with shock loads greater than 300%, consult an SMA Application Engineer.What are the standard input speeds?In general terms, the speeds are 1750 and 1165 RPM at 60Hz, and 1450 and 980 RPM at 50Hz. Theselection tables in this catalog are based on 1750 RPM. When other input speeds are used, the horsepower and torque ratings will vary.What are the thermal limitations of the Cyclo HBB?The Cyclo speed reducer, by virtue of its smooth, almost frictionless operation (unlike traditionalhelical gears), has a thermal rating that far exceeds its mechanical capacity and all but eliminates theconventional limitations due to heat.Why is a Taper-Grip bushing used? What is its material?The Taper-Grip bushing is integral to the Cyclo HBB and provides for easy mounting and removalto and from the shaft of the driven machine. Because it requires no keyway, the shaft isn’t weakenedand maximum torque is transmitted. With the added strength of steel, the Taper-Grip bushing can beused in reversing and/or high start-up applications. The steel Taper-Grip bushing can be used on allTaper-Grip products.What kind of torque arm do you supply? At what position should it be mounted?The standard torque arm assembly is shown in the gearmotor dimensions, pages 2.52 - 2.63. Thetorque arm should be mounted at 90 degrees to a line from the point of attachment to the reducer andthe center of the output bore with plus or minus 15 degrees variance. It should always be mounted intension, not compression. T-type and flange-mount (banjo) torque arms are also offered as options.Cyclo HBBDouble Reduction, C-FaceReducer with Torque ArmC-Face Reducer with ScrewConveyor AdapterGeneral Information 1.5
Cyclo HBBEnhanced Performance (EP) Motors FAQsWhat efficiency level are these Enhanced Performance (EP) motors?The EP motor is a Premium efficiency class, or International Efficiency 3 (IE3) design.What standards do these motors meet?This motor line is compliant with the Energy Policy and Conservation Act (EPAct), as recently amended by the Departmentof Energy with a new ruling. The DOE expands the scope of covered motor products to include previously exempt motors,such as gearmotors and brakemotors. Compliance to the new ruling starts on June 1, 2016.These Sumitomo motors met the efficiency levels promoted by the Consortium for Energy Efficiency (CEE) and exceed theCanadian efficiency levels specified by NRCan.The IE3 efficiency ratings conform to both the IEC Standard 60034-30:2009 and eco-design directive 2005/32/EC.Will these motors work with inverters?All current SMA motors feature corona resistant magnet wire that extends the life of the insulation and enables the motorsto resist the voltage spikes common with IGBT variable frequency drives.What agency listings apply?All motors in this product line are UL recognized, CSA certified and CE marked.Can the EP motors be nameplated to operate at 50 hertz?The EP.NA motor can be nameplated and will operate at 50 hertz, but depending on the export destination, it may not meetthat country’s energy efficiency requirements. For areas requiring IE3 performance at 50 hertz, like Asia and Europe, other 50hertz specific versions of the EP motors can be provided.Is the selection procedure the same as previous gearmotors?Similar, the difference is restricted to applications with a large number of across the line starts and stops. Because the EPmotors have more inertia and higher inrush current than previous integral motors, a supplemental service factor is appliedto these applications using EP motors.Are the brakes the same?The brakes are the same direct acting, fast response types used previously. They are a new larger model that has beenredesigned to match the new motor profiles. Because the EP motor inertia is significantly higher, it may be necessary toadjust external trigger points or limit switches. Since the brake assembly shapes are different, old and new parts are notinterchangeable.What is the standard insulation system?The EP motors continue with the Class F system, which limits the temperature rise to a Class B rise, where it bounds theallowable temperature rise to 80 C. It utilizes an insulation system capable of handling a 105 C rise to significantly extendinsulation life.Are EP motors interchangeable with old AF-motors?The new EP motors without brake have the same 10:1 constant torque speed range as the AF-motor. Motors aredimensionally and performance-wise different so VFD re-programming will be required. For EP brakemotor with use onVFDs, the applicable speed range may be limited. Please consult the factory for options for EP brakemotors.Will old motors continue to be available?EP motors will eventually replace the older motors. Older motors do not meet the federally mandated efficiencyrequirements that go into effect on June 1, 2016. Non-compliant motors after that date cannot be manufactured orimported into the United States.Should I be concerned if I am replacing an older motor with the new EP motor?For most applications, the use of the new EP motor will result in a more efficient, cooler-running and energy-saving motor.However, for applications with certain performance constraints, you may need to review the impact of the following:- larger dimension and weight- larger moment of inertia- higher starting current and torque.1.6 General InformationCyclo HBB

Designing Helical Piles per the IBC 4.1 Introduction Helical piles and anchors have been used in construction applications for more than 175 years. However, there was not a uniform standard of testing helical systems until the International Code Council (ICC) approved the Acceptance Criteria for Helical Foundation Systems (AC358) in June 2007.
project type, helical piles were recommended as the most efficient method of supporting this project. A series of 117 helical piles were installed to a depth of 3.65 m below grade. 12 of these were 88.9 mm round, hollow steel shaft helical piles, with a 203, 254, and 305-mm triple helical configuration. These piles were installed
