AI Technical Summary
Technical Problem
During long-term use, the bearings of existing torque motors are prone to wear and misalignment, leading to axial displacement of the rotor and affecting the stability and output efficiency of the torque motor.
Method used
By setting rotor knobs and housing knobs in the torque motor, the distance between the inner and outer rings of the rotating bearing can be adjusted. By utilizing structures such as bearing abutment rings and limiting springs, the rotor shaft clearance can be adjusted, reducing the adverse effects of wear and loosening.
Benefits of technology
It effectively reduces displacement caused by bearing wear and loosening, ensures rotor stability and magnetic field coupling, and improves the long-term stability and output efficiency of the torque motor.
