Retrofit VRM of drive systemInnovative Power Transmission

RENK Aktiengesellschaft Industrial Gears 05/15 2

Spare gear / Replacement ProjectsReplacement of other than RENK made VRM drives

Customer will receive a 1:1 under mill replacementd- all interfaces to mill & foundation are kept- the Change Gear is replaced by VSDS- torqe limiting HYGUARD is installed- the mill speed is adapted as per spec- substantial increase of safety margins likely

The current motor is kept or upgraded

A new state of the art oil system withtank and fine filtation is quoted.

An advanced server based CMS RENK VIBmonitor with torquemeassurement is quotedd

KPBV features compared to other designs

• bullet proof round pad hydrostatic axial bearing - no failure since more than a decade

• better cooling with radial oil flow more oil film thickness

• axial bearing oil and tooth lubrication oil of output planetary stage clearly separated and therefore lower integral temperature of annulus and more safety against scuffing

competitor

• Metal hose protection! Longer hose life!

RENK Aktiengesellschaft Industrial Gears 05/15 7

KPBV features compared to other designs

• more mature bearing concept for the bevel gear pinion (especial axial bearing concept)

• more safety against tooth rupture due to larger modules in planetary stage

• Carrier separate from thrust ring

• nearly 10 more years of experience in 3 stage VRM drives than any other competitor
