Introduction

Hung H Pham is a notable inventor based in San Jose, California. He has made significant contributions to the field of linear actuators, holding a total of three patents. His work focuses on enhancing the functionality and efficiency of electromechanical systems.

Latest Patents

One of his latest patents is the "Linear captive motor-leadscrew assembly." This invention features a captive leadscrew-type linear actuator assembly that includes a motor with a rearward extending hollow bore shaft. An external nut assembly, fixed to the bore shaft, rotates with the rotor and engages a lead screw. The design incorporates an anti-rotation radial support plate that prevents rotation of a rod or piston attached to the lead screw, converting torque into linear motion. This innovation allows for greater design flexibility, improved motion accuracy, and enhanced durability.

Another significant patent is the "Anti-backlash mechanism for electromechanical linear actuator." This invention utilizes a radial-type anti-backlash nut designed for linear actuator leadscrews. It features a separate housing that rests upon the actuator's main nut, employing a multi-finger collet and spring setup for anti-backlash action. The design allows for adjustable load force on the collet fingers against the leadscrew, enhancing the precision and reliability of the actuator.
