Structural Design and Analysis of Mine Flameproof Electric Actuator

Abstract

According to the power supply environment in the coal mine and the operating requirements of the electric control of small diameter valves in the waterway network, the appropriate mechanical transmission structure of the mine electric actuator is designed, and the overall design and detailed transmission design are completed, Check the tooth surface contact strength and tooth root bending strength of the transmission gear. Through the analysis and strength check of the force on the gear shaft, meet the material requirements. Through the finite element analysis software, the hydrostatic pressure loading analysis of the flameproof shell is carried out. The calculated structural strength and stiffness meet the requirements, providing a theoretical basis for the reliable and stable operation of the mine flameproof electric actuator.
