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
competitor RENK
Existing HP & LP Piping,Replaced by a new pipesthicker drain line)
Existing Lubrication system,Replaced by a new system featuring morevolume in a tank on same footprint
Existing Gear unit, replaced byKPBV (low invest, ultimate dependability)
Replacement items
Interface-Adapters Are not envisaged
Change Gear isreplaced byDouble Link & HYGUARD coupling
