Anti-loose high-temperature alloy lock washer and manufacturing method thereof

The invention belongs to the technical field of aero-engine manufacturing and repairing, and discloses an anti-loose high-temperature alloy lock washer which comprises a ring part. Two locking claws are arranged on each of the left side and the right side of the ring part, a lock claw is arranged at the bottom of the ring part, the length of the lock claw is 4-8 mm, and the lock washer is made ofGH3044. According to the anti-loose high-temperature alloy lock washer, the failure rate of falling of heat shield nuts in the using process of an aero-engine of a certain type is effectively lowered,the stability of the engine and assembling efficiency of operators are improved, the flight quality is guaranteed, and regular checking, fault repairing and repeated test-run costs are saved. 本发明属于航空发动机制造、维修技术领域，公开了种防松高温合金止动垫圈，包括圆环部，所述圆环部左右两侧分别设置有两个锁紧爪，圆环部底部设置有止动爪，止动爪的长度为4-8mm，止动垫圈采用GH3044材料制成；本发明的防松高温合金止动垫圈，有效降低某型航空发动机使用过程中隔热屏螺母脱落故障率。提升了发动机稳定性并且提高了操作者的装配效率，保障了的飞行质量，节约了定检、故障修理、重复试车成本。
