Using Grease for Gear Lubrication

Polyurea is the thickener portion of the grease and can affect some of the finished lubricant's functional properties, such as the dropping point, consistency and water-wash resistance. However, simply referring to a grease by its thickener type does not provide enough information as to its true performance characteristics.

Thickener Torque -Rakes & Drive

This is designed this way to give the bed a slope towards the centre of the thickener. As the rakes are turned by the drive shaft they cause the concentrate that has settled onto the bottom of the thickener to be pulled into the discharge chamber at the centre of the thickener. This is called the CONE.

Limitorque Gearboxes | Flowserve

Gearboxes such as the WG, V, or SR series provide the mechanical advantage to make hand operation possible for most valves. Where automated process control is needed or torque requirements are too high for manual operation to be practical, these gearboxes can be coupled to MX, L120 or SMB actuators.

Efficient high-density thickeners | FL

High-density thickeners have a deeper sidewall and increased torque to improve underflow densities at a lower cost. Thickening is key to a thriving operation. Sometimes you need extra torque for high underflow densities. The High-density Thickener packs a punch with plenty of extra torque in a design between a high-rate and deep cone thickener.

Will thicker oils make for a quieter gearbox/drivetrain?

I was contemplating gearbox, transfer, diff and overdrive oils. Will the use of a thicker/heavier grade of oil, if such a thing exists, or alternatively oil additives that thicken your oil, make the drivetrain better and quieter? The old trick of thickening the oil with sawdust to quieten a noisy transmission springs to mind.

Thickener Torque -Rakes & Drive

A little earlier I talked about the rakes of the thickener, these are long arms that extend off of the bottom of the DRIVE SHAFT. As the shaft turns the rakes will sweep the entire bed of the thickener thereby applied Torque. Each rake arm is higher at its far end than it is where it joins the drive shaft. This is designed this way to give the ...
