Cyclo® Helical Buddybox Gearmotor

Yes, we have 6 different torque arm options to make your installation easy.

No problem, your Sumitomo rep can assist with that, we can instruct you how, or you can send it to us to do.

The BBB has a different design when it comes to the backstop.

• Our backstop is at the high-speed shaft achieving lift off easily and not creating drag and wear on the spragues
• Our backstop being at the high-speed shaft sees the least amount of torque. The combination of the backstop ratings being higher, and seeing less torque, results in a long life
• Our backstop is maintenance-free (no lubrication maintenance) and is sealed off from the reducer protecting the reducer from the backstop and the backstop from the reducer. There is no unified lubrication system between the two.

Not by changing a sheave size since that component is eliminated, but there are things to consider…

• How often are you really changing the speed?
• The flexibility of changing a sheave size also puts your system at risk. Are you overspeeding beyond the reducer's capabilities? Are you slowing down too much and causing the backstop spragues to drag and wear?

If you are utilizing a VFD, that can control your speed.

• If you find out you truly need to change your speed, our BBB is the only direct drive on the market that has a Cyclo cartridge that could be changed to change your overall speed eliminating the need for a whole new reducer. Work with your Sumitomo rep to consider this.

No, you can order a c-face transition kit from your motor manufacturer and turn a footed motor into a c-face motor very easily. We have other options we can provide if you absolutely can not replace or change your motor to a c-facemotor.

Our BBB (for typically 50hp and under depending on ratio) is designed for momentary high shock load – higher than any direct drive in the industry through utilizing our Cyclo technology. Another safeguard that can be put in place include the following:

• BBB’s are designed and sized where the motor would amp out before any damage would be done to the reducer
• Can adjust the motor heater for additional safety measures if desired
• A torque limiting or shear coupling could be used within the c-face adaptor as an additional safety measure if desired

Yes, if our standard Taper Grip Bushing requires more shaft than you have, we have a new Taper Grip Bushing option that needs an average of ½ the shaft length. When we size up the reducer you need, we can tell you how much shaft length you need for both options.

In general, reducers and gearmotors are rated for specific conditions and operating requirements of the application by the use of AGMA-defined Service Factors.  There are three AGMA load classifications for reducers: uniform (U), moderate shock (M) and heavy shock (H), and three AGMA load classifications for gearmotors: I, II, and III. Refer to our catalog for a list of AGMA load classifications. These Service Factors are used in the product selection process to adjust for the specific conditions and operating requirements of your application.

The mounting positions for the Cyclo^® HBB detail the position of the unit relative to the driven shaft. The mounting position effects how the unit is assembled and maintained (i.e., location of oil fill ports, type of lubrication, breather location, etc.). You must specify the mounting position at the time of order.
