( ) 4 Error
( ) 5 Error
The error can be reduced by increasing the accuracy of the gear factors. By using the
2 decimal places of parameters
Factor Denominator
Optimization of gear factors"), accuracy can be increased.
At a maximum travel distance of 10 m, the following is obtained:
Non-optimized gear factors
Distance_nominal [rev] = 1 000 000 rev
Distance_actual [internal] = 23 633 609
Distance_actual [rev] = 1 000 131 rev
Error [rev] = 131 rev
Error [m] = 0.00131 m
Error [mm] = 1.3 mm
