Maximum Rotation Frequency Regulators of High-Speed Small-Sized Pneumatic Actuators

摘要

The problems of the development of maximum rotation frequency regulators and their use as a part of high-speed small-sized pneumatic actuators were considered. It is noted that widely used at the present time maximum rotation frequency regulators with mechanical frequency sensor are not sufficiently reliable at high rotation frequencies due to the presence of mutually moving elements. The authors developed a fundamentally new constructive scheme of maximum rotation frequency regulators, containing the elastic ring, which combines the functions of executive and sensitive elements. Regulators can be installed in the input and in the output section of the energy module of the pneumatic actuator. It is rioted that maximum rotation frequency regulators installed in the output section can be used in conjunction with any known types of the energy module of pneumatic actuator. A structural scheme of the regulator for relatively low-speed machines, which implements the longitudinal deformation of the elastic ring, was proposed. The developed maximum rotation frequency regulators showed good sensitivity, reliability, performance and energy efficiency. The created regulators can be used in a wide range of operating parameters of pneumatic actuators.
