I have a design that requires a gear pinion to drive a larger geared component. The large component will have a gear ring on its outer edge. The pinion can be of any material. To give an idea of scale, the pinion will be about 10mm in diameter and the larger gear about 50mm. Size of teeth etc not yet defined. The load is not great but the pinion speed will be up to about 1000rpm an an intermittent basis.
These parts need to run in water and the design dictates that alternatives i.e. sealing and providing grease lubrication are not possible.
Does anyone have experience of running gears in water like this?
