Dura­bil­ity and flex­i­bil­ity for heavy duty ap­pli­ca­tions

DEMM Engineering & Manufacturing - - MOTORS & DRIVES -

Bon­figli­oli is in­tro­duc­ing new sizes for its proven HDO drives to en­hance flex­i­bil­ity and dura­bil­ity in heavy duty ap­pli­ca­tions such as min­ing, bulk ma­te­ri­als han­dling, build­ing and con­struc­tion, food and bev­er­age and wa­ter and wastew­a­ter re­cy­cling.

The new HDO sizes – 71, 81, 91 and 95 – com­ple­ment the ex­ist­ing Bon­figli­oli range from HDO 100-180, which cater to torque re­quire­ments from 31,790 to 209,900 Nm. The new smaller sizes have torque out­puts from 6,800 to 23,200 Nm and are made from a monobloc hous­ing de­sign for added rigid­ity.

The new HDO sizes have sig­nif­i­cant ad­van­tages in ar­du­ous ap­pli­ca­tions and harsh con­di­tions com­mon in Aus­tralasian in­dus­try. For ex­am­ple, the HDO drives use case hard­ened gears, which are stronger and more durable.

The HDO is a rec­tan­gu­lar bevel hel­i­cal gear­box, as op­posed to square hel­i­cal bevel gear­boxes used in less de­mand­ing ap­pli­ca­tions. The back­stop (or anti-run- back) is po­si­tioned on the out­side of the HDO drives, which makes it eas­ily ac­ces­si­ble for main­te­nance. The whole drive does not need to be dis­man­tled to ac­cess it.

An­other in­no­va­tive fea­ture of the new HDO gear­boxes is their sym­met­ri­cal de­sign. They are de­signed with both hor­i­zon­tal and ver­ti­cal sym­me­try for ease of in­stal­la­tion tion in a wide va­ri­ety of cus­tomer ap­pli­ca­tions.

Ap­pli­ca­tions that will ben­e­fit from the new HDO sizes in­clude float­ing cells, apron feed­ers, con­vey­ors, cranes, bucket el­e­va­tors, as­phalt and other mix­ers, aer­a­tors and band screen­ers, says the man­u­fac­turer.


The new HDO sizes will also come with an ATEXcer­ti­fied op­tion for us in ex­plo­sive at­mos­pheres, the HDO-EX. This op­tion comes with com­pli­ance cer­tifi­cates for paint­ing, sur­face pro­tec­tion, mount­ing and sen­sors, along with ATEX ap­pli­ca­tion ver­i­fi­ca­tion.

HDO-EX drive stan­dard op­tions in­clude:

• Equipped with ser­vice plugs for pe­ri­odic lubri­cant level checks.

• Equipped with vent caps with anti-in­tru­sion valve.

• Flu­oro elas­tomer seal rings.

• No plas­tic com­po­nent parts. • Name­plate in­di­ca­tion of the prod­uct cat­e­gory and type of pro­tec­tion.

• Com­po­nents op­er­a­ble at above the op­er­at­ing tem­per­a­ture.

• Tem­per­a­ture in­di­ca­tor sup­plied with each unit.
