The silent inno­va­tion for com­bines increas­ing capac­i­ty and driver’s com­fort

“Silen­tium Dri­ve”, the inno­v­a­tive con­vey­ing sys­tem for com­bine har­vesters with rub­ber-fab­ric trac­tion belt­ing with par­a­bol­ic cams abol­ish­es one of the major nois­es in com­bine har­vesters and reduces wear of the inflex­i­ble all steel chain and its dri­ve com­po­nents.

Thanks to the impres­sive nov­el­ty made by Jäger, the tremen­dous noise of cross bars hit­ting the box sheet met­al con­struc­tion, as usu­al in con­ven­tion­al­ly pro­vid­ed com­bine har­vesters, can be dimin­ished.

Con­cept of “Silen­tium Dri­ve”

The “Silen­tium Dri­ve” is based on a rub­ber-fab­ric trac­tion belt­ing with par­a­bol­ic cams that replaces the steel roller chain. This cam-belt­ing is man­u­fac­tured in two vari­ants: a tru­ly end­less wrapped loop or with over­lap­ping ends with a spe­cial con­nec­tion method. The mount­ing bolts for the cross bars are vul­can­ized into the cam-belt­ing for an opti­mal con­nec­tion between belt and cross bars.

In the heart of “Silen­tium Dri­ve” the Broeke­ma N‑type dri­ve wheels inter­mesh­es with the cams of the belt­ing. The return end of the con­vey­or is real­ized by a con­tin­u­ous roller across the full width of the belt or sin­gle return wheels per belt­ing.

Com­bines of any major brand can be con­vert­ed from steel roller chain to “Silen­tium Dri­ve” with lit­tle effort pay­ing for itself quick­ly. Only few com­po­nents need to be either replaced or mod­i­fied.

Fea­tures of the “Silen­tium Dri­ve

The “Silen­tium Dri­ve” increas­es com­fort and dri­ver-friend­li­ness dur­ing thresh­ing thanks to its spe­cial fea­tures. As the steel bars of the chain no longer touch the floor of the man­hole, noise emis­sions are min­imised. In addi­tion to elim­i­nat­ing the main source of noise from the com­bine direct­ly under the driver’s cab, the mate­r­i­al flow is also very even and qui­et. Thanks to the par­a­bol­ic rub­ber-fab­ric cam belt, the “Silen­tium Dri­ve” has excel­lent dynam­ic strength and pulling pow­er as well as high elas­tic­i­ty in the event of for­eign bod­ies being drawn in.

Val­ue added by “Silen­tium Dri­ve”

Fur­ther­more, “Silen­tium Dri­ve” con­tributes to low­er main­te­nance costs:

  • Mul­ti­ple longevi­ty in com­par­i­son with steel roller chain
  • Increased con­vey­ing speed and capac­i­ty
  • Min­i­mal chain wear
  • Min­i­mal wear on dri­ve wheel and return rollers
  • Lit­tle main­te­nance required
  • High­est reli­a­bil­i­ty
  • Avoids field break-downs
  • Gen­tle on dri­ver and envi­ron­ment due to low noise emis­sions
  • Unprece­dent­ed ease of use
  • Low­est cost per acre over chain life

Over sev­er­al years “Silen­tium Dri­ve” was pro­fes­sion­al­ly devel­oped and thor­ough­ly test­ed by Broeke­ma – the spe­cial­ist rub­ber and crop con­vey­or com­pa­ny with decades of expe­ri­ence in the agri­cul­tur­al machine indus­try.
