Description

[0001] The utility model relates to the technical field of T-type screw rods, in particular to a T-type screw rod actuator. Background Art

[0002] In the field of underwater operations, robots and drones are used to replace manual operations in highly dangerous environments, polluted environments, and waters with zero visibility for long periods of time. In the process of using robots and drones for underwater operations, the rotational motion of robots and drones must be converted into linear motion. Therefore, a T-type screw actuator is required.

[0003] In the prior art, since the sealing of the outside is generally not very good, when robots and drones are used to replace manual labor for underwater operations, water is easily allowed to enter the inside, which may cause them to malfunction, making it impossible for robots and drones to replace manual labor for underwater operations, increasing the difficulty of their underwater operations. In the prior art, when robots and drones are used to replace manual labor for underwater operations, when the rotational motion of the robots and drones is converted into linear motion, the rotational motion of the robots and drones is generally converted into linear motion through deep groove ball bearings. The load borne by robots and drones during underwater operations is large, and the load-bearing capacity of deep groove ball bearings is slightly weak, which may cause the deep groove ball bearings inside to wear more severely, thereby increasing the possibility of damage and shortening their service life.
