Patent number: 10637324Abstract: An electric actuator includes a motor having a rotary shaft. The electric actuator further includes a vibration damping gasket mounted on the motor. The vibration damping gasket includes an annular body attached around the motor and an end wall formed on one end of the annular body, and the end wall defines a through hole allowing the rotary shaft to pass therethrough. The motor further includes an outer housing, and the annular body of the vibration damping gasket is attached around the outer housing. The end wall of the vibration damping gasket contacts with the end surface of the outer housing. The vibration damping gasket is made from a resilient material. The electric actuator can effectively reduce the mechanical vibration, improve a buffering effect thereof, and hence reduce the noise.Type: GrantFiled: March 21, 2017Date of Patent: April 28, 2020Assignee: JOHNSON ELECTRIC INTERNATIONAL AGInventors: Dao Long Xiao, Jing Xin Shi, Yuan Feng Liu, Si Jun Zhao, Hong Min Wei, Shu Ze Li, Bin Liu, Xiang Chun Duan, Hui Juan Xing, Fei Fei Huang
