Rotary Gearboxes |

Design Tools |
|
Saia motors gearboxes are available in a variety of sizes to meet a wide range of torque requirements. Ratios from 4 1/6 to 6.048.000 are available. Different output shafts are available. The basic design is a spur gearbox with gear wheels in metal, plastics and combinations of the two materials. A particular feature is the availability of freewheels and slipping clutches.
Gearbox types UGA, UGB and UGD can be fitted with freewheels or slipping clutches. Freewheels transmit the max. torque M in the locked direction, <1 cNm in the opposite Direction. One way slipping clutches behave similarly except that the slip torque has a higher value. Two way slipping clutches can only transmit a limited torque value in either direction lower than the slip torque. Slipping clutches are used to: Protect the gearbox against torque overloads, or to adjust the load by turning from the load side (remember: turning the output shaft directly can otherwise damage the gearbox).
