LINEAR ACTUATOR OF HYDRAULIC STRUCTURES Russian patent published in 2021 - IPC F16H25/20 

FIELD: linear actuators.

SUBSTANCE: invention relates to linear actuators and can be used as a power drive in various hydraulic structures. The linear actuator contains a housing in which a rod is placed, which can move along its axis, the rod is secured against rotation by means of a segment key. The ball screw is installed in the rod and connected to the rod and housing through a ball screw with a nut and a cage installed on it, the cage contains spherical roller thrust radial bearings. The screw is connected to the electric motor through a planetary gearbox, the end of the rod is connected to a spring damper, which is made of Belleville springs and support washers interacting with Belleville springs on each side.

EFFECT: increased reliability and resource, simplified design, improved technical characteristics, expanded functionality.
