Bearings axial forces

When transmitting the load to the driven equipment, the motor bearing at the driving end (DE) is normally subject to two types of forces, radial and axial. The axial force in a horizontal drive is normally zero. If it is not zero this may be due to eccentricity in the transmitting line or any such reason that may subject the driving end bearing to an axial load in addition to a radial load. These forces become severe when the load from the motor is being...

The axial force is transmitted from bearing to bearing via precisely matched bushings, with each individual bearing absorbing the same force. 

Bearings allow relative rotational and translational motion between two machine parts. Apart from transmitting radial and axial forces (in rotary bearings) and forces and moments transverse to the direction of motion (in linear bearings), they define the relative positions of the machine elements supported by the bearings. 

Originally developed for natural rubbers, foodstuffs, and elastomers, at present these machines are used as a stirred tank reactor or a twin-rotor continuous mixer. Their bearings are exposed mainly to radial, not axial, forces. By using one screw longer than the other, one can separate the mixing and pumping functions.

Thrust bearing is used to handie the axial hydraulic imbalance in a compressor. For multistage unit, balancing drum or back-to-back impeller arrangement are used to reduce the axial force imbalance. 

Determine the axial force on the bearing from working condition.
