Abstract
The present invention pertains generally to a self-locking gear that includes an input shaft, a collar, a locking mechanism, and an output member. The collar is positioned eccentrically about the input shaft, and the locking mechanism prevents the collar from rotating. As a result, rotation of the input shaft causes the collar to gyrate about the input shaft, and the gyrating collar engages with the output member to turn the output member in the same direction as the input shaft. Torque applied to the output member with cause the output member to attempt to rotate the collar. However, the locking mechanism prevents the collar from rotating, thus locking the output member from rotation.
Claims20
A self-locking gear comprising:
- a. an input shaft;
- b. a collar positioned eccentrically about said input shaft;
- c. an output member engaged with said collar;
- and
- d. a locking mechanism connected to said collar to prevent said collar from rotating, wherein said locking mechanism includes
- i. a first plate connected to said collar to allow movement of said collar in a first direction,
- ii. a second plate connected to said first plate to allow movement of said collar in a second direction, and
- iii. said first direction is generally perpendicular to said second direction.
A self-locking gear comprising:
- a. an input shaft;
- b. a collar positioned eccentrically about said input shaft;
- c. an output member engaged with said collar;
- d. a first bracket pivotally connected to said collar;
- e. a second bracket pivotally connected to said first bracket;
- f. a base pivotally connected to said second bracket;
- g. wherein said first and second brackets prevent said collar from rotating.
A self-locking gear comprising:
- a. an input shaft;
- b. a collar positioned eccentrically about said input shaft;
- c. an output member engaged with said collar;
- and
- d. a locking mechanism connected to said collar that prevents said collar from rotating.
