A quick recovery to full manufacturing capacity is a criterion that SEW-Eurodrive understands. The company recently had a rotary cooking pot back to full operation within a week.

SEW-Eurodrive Durban examined the fairly old rotary cooking pot breakdown at an animal feed plant which had suffered a transmission failure. “An inspection of the broken unit showed that our MC Series Helical Bevel IG Unit would be the perfect replacement solution, and that we could do a drop and install process to shorten downtime,“ says Clive O’Reilly, SEW-Eurodrive, Durban Branch Manager.

“As solution specialists, we understand the need for a quick return to operational activity. Our unit, that replaced the old worm styled gearing unit, is not only more compact due its modular design but has far fewer variables. In addition, the helical bevel system has increased torque capacity, broader gear range ratios and delivers higher efficiency. The motor also connects directly to the gearbox. 

“Substantial cost savings of over 26% were achieved by using our unit rather than attempting to repair the old gearbox. In addition to installation and commissioning within seven days, the unit offered an improved operating power of 55kW down to 37kW and a mechanical efficiency of 95%. The rotary cooking pot was back in service in quick order,” says Clive.

For this application, the MC Series Helical Bevel IG Unit has an AC-motor. The input shaft has a depth and length of 50 x 100mm with the output shaft having a depth and length of 130 x 220mm. The left and right shaft positons are enabled through a single housing.The motor power is a nominal PM (kW) 37.00, and input speed of n1(rpm) 1475. 

The MC Series features SEW-Eurodrive‘s Extended Bearing Distance (EBD) concept which offers stronger bearings within the gear unit itself. This means that in many cases separate bearings are no longer required in the agitator or an oversizing of the gear unit can be avoided. The concept is supplemented by an optional dry well seal, which prevents oil leakage at the output shaft.
