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 for a linear actuator comprising:
- a ball nut having one or more rows of lock protrusions extending radially from an external circumference of the ball nut;
- and
- a lock rotor configured to encircle the ball nut, the lock rotor having a row of ridge protrusions extending radially inward from an internal circumference,
- wherein the ridge protrusions are aligned with locking protrusions of the one or more rows of lock protrusions when the linear actuator is in a first position, and are misaligned with the locking protrusions of the one or more rows of lock protrusions when the linear actuator is in a second position.
A lock assembly comprising:
- a lock nut having a plurality of lock protrusions extending radially from an external circumference of the lock nut;
- a lock rotor configured to encircle the lock nut, the lock rotor having a plurality of protrusions extending radially inward from an internal circumference;
- and
- a linear actuator connected to the lock rotor and configured to move the lock rotor from a locked position to an unlocked position.
A lock assembly for a linear actuator comprising:
- a ball nut having one or more rows of lock protrusions extending radially from an external circumference of the ball nut;
- and
- a lock rotor configured to encircle the ball nut, the lock rotor having a row of ridge protrusions extending radially inward from an internal circumference,
- wherein the ridge protrusions are arranged between locking protrusions of the one or more rows of lock protrusions in a lock position, and are arranged between adjacent locking protrusions of the one or more rows of lock protrusions in an unlock position.
