A ball bearing is a circular joint that connects a rotating part to another, usually stationary, part of a machine. It allows the rotating part to provide or receive structural support while significantly reducing the amount of friction caused by the rotation. Figure 1 shows an example of a selfaligning ball bearing.

The parameter ϵ is related to clearance in the bearing and the radial shift at the centre of the shaft. Its value can be interpreted as giving the proportion of the total bearing circumference which is under load (Harris and Kotzalas, 2007). Figure 1C shows an example radial load distribution for a rolling element bearing with ϵ≈ ...

where F 1 is the tension side force and F 2 is the slack side force. The quantity (F 1 F 2) is the net obtained from the horsepower flat belts, the value of C is between 2 and 3, depending upon conditions of installation. For Vbelts, use C = . The axial load produced from gearing must be obtained from considerations of the type of geartooth design used.

Gearboxes are frequently used in the mining industry, especially for power transmission between the electric drive and the ball mill; besides the extreme complexity of a ball mill gear transmission system, the fault diagnosis by vibration analysis can be easily distorted by the presence of impulsive noises due to the ball pulses on the mill shell. Although several works in the literature are ...
