| Abstract: |
| Aiming at higher thread strength, a lock nut with wedge thread is designed. And the factors that affect nut performance are identified. For uncertain elements, the verification scheme is given. And the comparision test is carried out. At last, the locking performance factors are confirmed, and the optimal design and experiment criteria are given, which provide theoretical reference for design. |
