HYPONIC® 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.

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.

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.

Do you supply a torque arm? At what position should it be mounted? A torque arm assembly is offered as an option. The standard torque arm assembly and standard mounting positions are shown in the Appendix of our catalog.

A hypoid reducer is more efficient than the traditional worm gear reducer.  The reason why a hypoid gear is more efficient than a worm gear is due mainly to two factors:  gear tooth profile and the material it is made of.  Hypoid gear is all-steel, while worm gear uses steel and a bronze wheel (that will wear down). 

The reducer’s radial load capacities are calculated at the midpoint of the slow speed shaft extension.  Radial load capacities decrease if the center of the load is moved farther from the reducer and the values obtained must be adjusted accordingly.  Refer to the Special Load Guidelines section in the Appendix of our cagtalog for load location factors.

Yes, loads imposed on the slow speed shaft will vary according to the method used to connect the shaft to the driven machine.  Frequently, in addition to the torsional forces, radial (overhung) and thrust loads are applied to the slow speed shaft at the same time.  For example, coupling connections normally involve torsional forces only.  However, when power is transmitted through spur gears, belts, pulleys, or chains, both torsional and radial forces may be present.  When driving through helical or bevel gears, all three conditions (torsional, radial, and thrust load) may be referred to the reducer shaft.  The slow speed shaft and bearings must have sufficient strength to withstand these loads, and it is necessary to determine the allowable limits for each condition.  The Special Load Guidelines section in the Appendix of our catalog explains how to calculate the overhung load (radial) applied to the output shaft.
