What kind of torque arm do I specify? At what position should I mount it?
The standard torque arm assembly supplied is a turnbuckle type as shown in our catalog. The torque arm should be mounted at 90 degrees to a line from the point of attachment to the reducer and the center of the output bore with up to 30 degrees plus or minus variance. A bracket type torque arm is also offered as a non-stock option. In addition, we provide the Banjo-type and T-type torque arm mounting configurations.
What are the advantages of the new Steel Taper-Grip® bushing?
With an increased torque capacity, the new Steel Taper-Grip® bushing can be used in reversing and/or high start-up applications. The new Steel Taper-Grip®bushing can be used on all Taper-Grip® products.
What are the advantages of the Taper-Grip® bushing?
The Taper-Grip® bushing is integral to the Cyclo® BBB4 and provides for easy mounting and removal to and from the shaft of the driven machine. Because it requires no key way, the shaft isn’t weakened and maximum torque is transmitted.
What thermal capacity limitations does the Cyclo® BBB4 have?
The Cyclo® speed reducer, by virtue of its smooth, almost frictionless operation (unlike traditional helical gears), has a thermal rating that far exceeds its mechanical capacity and all but eliminates the conventional limitations due to heat.
What are backstops?
Backstops are safety devices and have to be inspected at regular time intervals. The periodical inspection is to be carried out by authorized personnel. The frequency of the inspection depends on the type of application. Please refer to the P4 service manual for recommended inspection intervals
How can I be sure that the reducer can withstand periodic excessive overloads?
Cyclo® BBB4 Speed Reducers provide 300% momentary intermittent shock load capacity. For applications with shock loads greater than 300%, consult a Sumitomo Application Engineer.
Can the Cyclo® BBB4 handle severe operating conditions?
The standard ratings for Cyclo® BBB4 are based on 10-hour daily service under conditions of uniform loads (equivalent to AGMA service factor 1.0). By following the product selection process outlined in our catalog, you will determine and apply the Service Factors to compensate for the severe operating conditions.
What thermal capacity limitations does the Cyclo® have?
The Cyclo speed reducer, by virtue of its smooth, almost frictionless operation (unlike traditional helical gears), has a thermal rating that far exceeds its mechanical capacity, and all but eliminates the conventional limitions due to heat.
Can my Cyclo® handle severe operating conditions?
The standard ratings for Cyclo are based on 10-hour daily service under conditions of uniform loads (equivalent to AGMA service factor 1.0). By following the product selection process outlined in our catalog, you will determine and apply the Service Factors to compensate for the severe operating conditions.
What information do I need to select a Cyclo® speed reducer or gearmotor?
To select the proper reducer for your application, you need to know: Application: type of driven machine
Hours of operation per day
Motor horsepower (HP) and speed (RPM)
Mounting position
Ambient environment (altitude, dusty, chemical, explosive, water)
Ambient temperature and humidity
You must also note any special environment factors or operational requirements. This information will be important in determining your application's service factor.
