Gear unit - Import export

For closed gear units and geared motors, plain and friction bearings even at higher rotating speeds, e.g. on filling and packaging machines For joints, propeller shafts and chains when grease lubrication is specified Advantages and benefits Toxicologically harmless as defined in German LFGB Formula in accordance the FDA guideline 21 CFR 178.3570 NSF H1 registered Long operating times due to good resistance to oxidation and ageing Reduced wear due to highly adhesive, load-bearing lubricating film Excellent corrosion protection Low dynamic viscosity enables use with minimal bearing play and gear unit spaces Good pumpability with central lubricating systems Very high resistance to hot and cold water, watery-alkaline and acidic disinfectants and cleaning agents

Lubrication of heavy loaded toothed gears and worm gears exposed to outdoor conditions and/or low temperatures, as well as tilted or vertical shafts, especially with gear designs which are not oil-tight Lubrication of friction bearings with minimal bearing clearance or high circumferential speeds Advantages and benefits Long-term lubrication due to excellent resistance to oxidation and ageing Wear reduction at maximum loading Prevents leakage with angled or vertical shafts due to good adhesion on metallic surfaces Flowing structure prevents grooving in gear units with continuous coverage of surfaces

Application The VD4HD/-30° can be used for refacing the external conical landing face on valve cages. Capacity Max. refacing diameter 250mm Angle of transverse feed -30° Features Drive unit and gear head of the VD4HD/-30° are identical with the drive unit and gear head of the VD4E Valve Seat Refacing Machine. If a VD4HD is already on hand, only the D4/-30° adapter head is required for refacing the external conical landing face on valve cages. The D4/-30° adapter head is bolted to the gear head in place of the seat refacing adapter head. The pilot used for valve seat refacing can be also used for centering the VD4HD/-30°.

Application The VD4HD-RC is designed for refacing • the landing surface for the cylinder liner on the engine block, • the landing surface for the cylinder head on the cylinder liner and • the landing surface for the cylinder liner on the cylinder head. Features Drive unit and gear head of the VD4HD-RC are identical with the drive unit and gear head of the VD4HD Valve Seat Refacing Machine. If you have already a VD4E machine and you want to use it with our new face turning heads, we can convert it into the new high performance VD4HD System. The three available face turning heads should be used according to our recommendation with the VD4HD drive unit and the related power supply type 4HD. We would be glad to advise you about our new VD4HD system and send you an offer for this. The D4/0° adapter head is bolted to the gear head in place of the valve seat refacing head. The VD4HD-RC is centered by a pilot assembly which is designed to fit to the engine component to be serviced.
