When tightening the thread of the locknut, firmly insert the thread of the anchor bolt into the clamped 30° wedge slope, and increase the normal force formed on the wedge slope to the axis of the anchor bolt. Clamped at 60 degrees. The angle of view is not 30°, so the normal force when tightening the locknut is much higher than that of the general standard nut, and it has good locking and vibration resistance. The lock nut is a kind of nut with high locking performance, which can work normally even under severe conditions. Generally speaking, lock nuts have three advantages: 1. Wear resistance and cutting resistance: The 30° slope at the bottom of the nut thread makes the nut locking force evenly distributed on all threads on each tooth. Due to the uniform pressure distribution on the thread surface of each tooth, the nut can more effectively solve the problems of thread damage and cutting deformation. 2. Excellent vibration resistance: After the screw is tightened, the thread of the anchor bolt thread is firmly inserted into the 30° wedge angle of the nut and clamped, and the normal force formed on the wedge angle is as follows. Vino. It is the same as increasing the normal force on the wedge slope. The centerlines of the anchor bolts are at a 60° angle instead of 30°, so the normal force caused by tightening the nut is much higher than the normal force. Standard nut with good fastening and shockproof properties. 3. Good reusability. If the dose is large, even if the nut is repeatedly tightened and disassembled, the locking force will not decrease, and the previous locking effect can be maintained. Locknuts have good corrosion and cut resistance. The bottom end of the thread of the locknut is skewed by 30 degrees, so there is a working pressure on each thread, so the locking force of the nut is evenly distributed on any tooth thread. Due to the uniform surface distribution, locknuts can more effectively solve the problems of screw damage and cutting deformation.
