Independent turbogenerator manufacturer BRUSH has released a new shaft driven oil pump gear coupling that it says significantly extends component service intervals from every 2000 hours to 45,000 hours, without supplementary lubrication requirements.

BRUSH says the launch is in response to market feedback and the new gear coupling incorporates curved tooth steel hubs and polyamide sleeve.

The company says this combination of materials allows for maintenance-free continuous operation with very low friction on the teeth.

“Due to the well-known effect of curved tooth gear couplings, any edge pressure in the spline in the case of angular and radial displacements is avoided, thereby minimising wear during operation,” it added.

BRUSH is the largest independent manufacturer of turbogenerators in the world with  plants in the UK, Holland, Czech Republic and China.
