Product Description

SC Transmission BK Series Bucket Elevator Gearboxes

Bucket elevators serve to vertically transport large masses of bulk material to different heights without creating dust, then dump it. The height to be overcome is frequently more than 200 meters. The weights to be moved are enormous.

The carrying elements in bucket elevators are central or double chain strands, link chains, or belts to which the buckets are attached. The drive is located at the upper station.

The features specified for the drives destined for these applications are similar to those for steeply ascending belt conveyors. Bucket elevators require a comparatively high input power.

The drive must be soft-starting because of the high starting power, and this is achieved by means of fluid couplings in the drive train.

Bevel helical gear units are normally used for this purpose as single or twin drives on a base frame or swing base.

Can I Use Synthetic Oil in My Gearbox?

Yes, you can use synthetic oil in your gearbox, and in many cases, it can offer several advantages over conventional mineral-based oils:

  • Improved Temperature Stability: Synthetic oils typically have a higher resistance to thermal breakdown, making them suitable for gearboxes that operate at high temperatures.
  • Enhanced Lubrication: Synthetic oils often have superior lubrication properties, providing better protection against friction, wear, and component damage.
  • Extended Oil Change Intervals: Synthetic oils can often withstand longer operating periods without losing their effectiveness, reducing the frequency of oil changes and maintenance.
  • Reduced Viscosity Changes: Synthetic oils are less prone to viscosity changes at different temperatures, ensuring consistent lubrication performance in varying conditions.
  • Lower Friction and Energy Loss: The smoother molecular structure of synthetic oils can lead to reduced internal friction, potentially improving gearbox efficiency and performance.
  • Cold Weather Performance: Synthetic oils generally flow better at low temperatures, making them suitable for gearboxes operating in cold climates.
  • Protection Against Oxidation: Synthetic oils often have better resistance to oxidation, helping to prevent the formation of sludge and deposits that can impact gearbox performance.

However, before switching to synthetic oil, it’s important to consider the manufacturer’s recommendations and specifications for your specific gearbox model. Some gearboxes may have specific requirements or restrictions on the type of lubricant to use. If the manufacturer approves the use of synthetic oil, it can be a beneficial choice, but if not, sticking to the recommended oil type is crucial to ensure proper gearbox function and warranty coverage.
