Introduction to the working principle of the lock washer

- Jan 21, 2019 -

  The lock washer consists of two washers with a radial rib on the outside and a slanted flank on the inside.


  The working principle of the anti-loose washer is very simple: when it is assembled, the inner oblique tooth surface is opposite, and the outer radial convex surface is in a meshing state with the contact surfaces at both ends. When the connecting member is vibrated and the bolt is loosened, only the permission is allowed. The two diagonal washers on the inside of the washer are relatively offset between each other, resulting in a lifting tension, which achieves a 100% locking effect. Lock washers can be used in all strong vibration environments.


  Anti-loose washer features: high safety performance; prevent looseness caused by vibration and power load; easy to install and disassemble; lock effect is not affected by lubrication; good locking effect regardless of pre-tightening force; can control pre-tightening force High and low; has the same temperature characteristics as standard bolts/nuts; reusable and more.
