Abstract
Methods and systems for a lock assembly for a linear actuator. The lock assembly includes a ball nut having one or more rows of lock protrusions extending axially from an external circumference of the ball nut. A lock rotor encircles the ball nut, the lock rotor having a row of ridge protrusions extending axially inward from an internal circumference. In a lock position, the ridge protrusions are arranged between locking protrusions. In an unlocked position, the ridge protrusions are arranged between adjacent locking protrusions.
Claims20
A lock assembly, comprising:
- a lock nut having at least one lock protrusion extending outwardly from an external surface of the lock nut;
- a lock rotor having at least one ridge protrusion extending inwardly from an internal surface;
- and
- an actuator connected to the lock rotor and configured to move the lock rotor from a locked position to an unlocked position.
1 more element
A lock assembly, comprising:
- a lock nut having a plurality of lock protrusions extending from an external circumference of the lock nut;
- a lock rotor configured to encircle the lock nut, the lock rotor having a plurality of ridge protrusions extending inward from an internal circumference;
- a rod connected to the lock rotor;
- and
- an arm that can be moved between a first position and a second position;
- wherein, when the arm is in the first position, the ridge protrusions of the lock rotor are aligned with the lock protrusions, and, when the arm is moved to the second position, the rod moves, causing the lock rotor to rotate such that the ridge protrusions are misaligned with the lock protrusions.
