Abstract
A self-locking mechanism, a motor, and a linear actuator, which relate to the field of self-locking mechanisms and have a stable self-locking performance. The self-locking mechanism includes a friction ring and a mounting seat fixed relative to the friction ring, a notch being provided on the friction ring, the friction ring being sleeved over a rotary body to be braked, a mounting portion for mounting the friction ring being defined on the mounting seat, the mounting seat pressing the friction ring towards the notch to apply a braking force against the rotary body.
Claims14
A self-locking mechanism, comprising
- a friction ring, a notch being provided on the friction ring,
- a mounting seat fixed relative to the friction ring, the friction ring being configured to be sleeved over a rotary body to be braked, the mounting seat being configured to press the friction ring towards the notch to apply a braking force against the rotary body, and
- a limiting structure configured to limit circumferential rotation of the friction ring relative to the mounting seat,
- wherein the limiting structure comprises snap-fit grooves provided on the mounting seat, a first raised edge provided on the friction ring at one end of the friction ring for being snapped in one of the snap-fit grooves, and a second raised edge provided on the friction ring at another end of the friction ring for being snapped in another one of the snap-ft grooves.
A self-locking mechanism, comprising:
- a friction ring, a notch being provided on the friction ring,
- a mounting seat fixed relative to the friction ring, the friction ring being configured to be sleeved over a rotary body to be braked, the mounting seat being configured to press the friction ring towards the notch to apply a braking force against the rotary body, and
- a limiting structure configured to limit circumferential rotation of the friction ring relative to the mounting seat,
- wherein the limiting structure comprises a plurality of raised edges provided on the friction ring, at intervals along an outer periphery of the friction ring, and a plurality of snap-fit grooves corresponding to the raised edges provided on the mounting seat.
A self-locking mechanism, comprising:
- a friction ring, a notch being provided on the friction ring, and
- a mounting seat fixed relative to the friction ring, the friction ring being configured to be sleeved over a rotary body to be braked, the mounting seat being configured to press the friction ring towards the notch to apply a braking force against the rotary body,
- wherein a mounting groove for accommodating the friction ring is defined on the mounting seat, and a snap joint for limiting the friction ring in the mounting groove is further provided on the mounting seat.
