### Drivetrain losses (efficiency)

The efficiency of a ball-bearing is around 0.99 and of a helical gear mesh around 0.98. With these nuers, we can calculate the overall efficiency of the gearbox. $\eta_{gbx}= 0.99^{4} \cdot 0.98^{1} = 0.941$ In reality the efficiency of the gearbox is not constant

### Use Of Ball Bearing Rollers To Increase The Efficiency The Machine …

30/1/2017· Ball bearing is a simple and very effective method of reducing the friction between the tyre rim and the axle of the vehicle, where one cylinder is attached to the axle and one is attached to the tyre rim. The two cylinders are of different diameters but co-axial in nature. The space between the cylinders is filled with small metal balls.
