Service Factor

10 hrs. per day, heavy shock 1.75 + 10 start/stops per hr. recommended supplemental service factor 1.50

1.75 + 1.50= 3.25(SF)

.75HP x 3.25SF= 2.44 input HP rating (needed)

----------------------------------------------------------------------

Torque

Application Requirement

T= HP x 63025/4.12

11,453.54 (in lbs.)= .75 x 63025/4.127

11,453.54 x .92 (efficiency loss)= 10,537.26 in lbs.

Output Coupling Connection Option Torque Rating Needed

10,537.26X3.25SF= 34,246.09 in lbs.

----------------------------------------------------------------------

SMA Technical/Engineering Application Examination

-SMA along with many other gearbox mfg.'s does not recommend hollow bore output with foot mounting.

-This rigid setup does not allow the gearbox to float, hence internal gearbox gearing damage/play begins

-The BBB3/BBB4 with both a Cycloidal disc and 3.2:1 spiral bevel creates to much play

-An inline/concentric reducer with less than 1% backlash is recommended

---------------------------------------------------------------------

Output Mounting Options

1.) Couple in Cyclo 6185DBY to existing driven shaft; no OHL exists or needs to be checked

(LSS coupling not included into quote, only input coupling)

2.) Custom build/replicate ABB wider output adaptor to fit onto the Cyclo LSS for proper connection and insurance

---------------------------------------------------------------------

45% Cost Savings
 

-At $20K per ABB gearbox, the Cyclo option allows for superior reduction components at about half the cost

-Estimated end user net price from distribution, roughly $13k
