En­hanced ther­mal per­for­mance of Tras­mi­tal 300M drives

DEMM Engineering & Manufacturing - - MOTORS & DRIVES -

To en­hance the per­for­mance of its Tras­mi­tal plan­e­tary gear­boxes, Bon­figli­oli is in­tro­duc­ing an in­te­grated fan op­tion on its new 300M se­ries. The fan is con­nected di­rectly to the IEC mo­tor, which leads to an im­proved ther­mal rat­ing and in­creased ther­mal power of up to 217 per­cent, de­pend­ing on the model.

Plan­e­tary gear­boxes are sta­ple work­horses for bulk ma­te­ri­als han­dling, min­ing process equip­ment, food and bev­er­age, ma­te­ri­als han­dling, wa­ter treat­ment, waste han­dling and heavy in­dus­tries. They typ­i­cally use a low speed and high torque for re­li­able per­for­mance in a com­pact space.

The high lev­els of torque to­gether with the com­pact na­ture of plan­e­tary gear units can lead to ther­mal re­stric­tions.

“The new ther­mal drives with in­te­grated fans run much cooler than their pre­de­ces­sors, which means they can safely utilise more torque,” ex­plains Mal­colm Lewis, Man­ag­ing Di­rec­tor, Bon­figli­oli Aus­tralia. “Be­cause more torque is avail­able, some ap­pli­ca­tions will be able to use a smaller gear­box to do the same job, sav­ing space, power and cost. The new range is ide­ally suited to hot cli­mates. Hav­ing an in­te­grated fan also has main­te­nance ben­e­fits, as there is no ex­ter­nal cool­ing unit. Ad­di­tion­ally, there are fewer over­all com­po­nents, which re­duces the chance of a small part fail­ure caus­ing the en­tire gear­box to need main­te­nance.”

The in­te­grated fan is con­nected to the IEC mo­tor flange in a com­pact and ef­fi­cient way, says the man­u­fac­turer. A key­way hol­low shaft con­nec­tion with the mo­tor means that no joint is re­quired. In­te­grated fins op­ti­mise the air flow and cool­ing sur­faces through­out the en­tire air con­veyor hous­ing.

“No ad­di­tional wa­ter or oil cool­ing sys­tem is needed with the in­te­grated fan, mak­ing it an even more en­vi­ron­men­tally friendly and sus­tain­able op­tion than op­tion than other cool­ing mech­a­nisms,” said Lewis.

The in­te­grated fan is de­signed to fit any size Bon­figli­oli or com­mer­cial mo­tor and the 300M se­ries has 100 per­cent in­ter­change­abil­ity with Bon­figli­oli’s cur­rent 300 se­ries mod­els, so no ma­chine mod­i­fi­ca­tion is re­quired when up­grad­ing to the new units. Ma­jor ap­pli­ca­tions for the 300M se­ries in­clude:

• Min­ing – car dumpers and stacker re­claimers.

• Ma­te­ri­als Han­dling – screw con­vey­ors and apron feed­ers.

• Cranes and Winches – jib cranes and ship load­ers.

• Food and Bev­er­age – spi­ral freez­ers and flak­ing ma­chines.

• Wa­ter and waste­water – mixer ag­i­ta­tors and band screen­ers.
