Application Scenarios:
When the downhole motor operates underground, the weight on bit (WOB) is transmitted to the motor body through the drill string, generating enormous axial loads. Meanwhile, the planetary cycloidal motion of the rotor also produces alternating axial forces.
The thrust bearing assembly (mostly multi-row cylindrical thrust roller bearings) is installed between the power assembly and the transmission shaft of the downhole motor, and its main functions are as follows:
Withstand the axial loads induced by the weight on bit, and prevent the axial movement of core components such as the rotor and transmission shaft.
Maintain the stable meshing clearance between the rotor and stator, so as to avoid seal failure and component wear caused by axial displacement.
Adapt to the harsh underground working conditions of high temperature, high pressure and heavy dust, and be provided with high load-carrying capacity, wear resistance and impact resistance.
