As soon as the nut/bolt is tightened, the radial outer toothing of the locking washer of the Lock screw presses against the contact surface. In this case, the angle of inclination α of the wedge toothing is greater than the pitch angle β of the screw thread.
Consequently, as the bolted joint loosens, the preload force increases. In addition, the friction value of the radial toothing of the outer surfaces of the washer is higher than the friction value of the inner side with wedge toothing. Thus, the combination of the pairs of washers in the application causes a more secure anti-rotation lock, even in the most challenging conditions.
When to use lock washers?
Washers are utilized with the fastener to give the nut a smooth, even surface, better disseminate the weights on the delicate material and forestall stripping. When is a lock washer required? Lock washers are required where the installation gathering depends on a vibration or where the backlash is viewed as an issue.
Does the lock washer ignite first?
A lock washer will hold the nut or other strung latch when utilized accurately. To accomplish this, place the lock washer under the latch first. Assuming your task requires different washers or equipment parts, they should be run before the secure washer holds them. By the help of lumbuy you can easily get lock washer to meet your need.
Uses & placement of Lock Washer
Versatile use. Lock Screw Locking Washers can be used without problem in threaded seats, oblong seats, through holes or in taps. For through holes, two pairs of Lock washers must be used. On the other hand, in the case of oblong holes and soft materials, Lock washer locking washers with a larger outer diameter is recommended. Note: Lock screw locking washers should not be used with unsecured washers.
Lock washers for the Twin-Lock screw during the test
With the lock washers, the preload is maintained on the joint. The following diagram shows the high anti-rotation locking capacity of Lock washers. Contrary to screws without fasteners (red line), the preload force remains constant throughout the loading period. The blue line represents the increase in force needed to loosen the joint after continuous load changes (click effect).
The locking washer system consists of two identical locking washers with a radial toothing on one side and a wedge on the other. This means that when the connection is released, the preload force is increased. The bolted joint is effectively secured even under intense vibrations and high dynamic loads.
Lock washer pairs are particularly recommended when the screw connections can loosen independently. Lock washers always provide effective locking, even in cases where severe vibrations and high dynamic loads may occur.
Optimal fixing solution
With locking washers, screw joints do not loosen accidentally, even in cases where there are intense vibrations and high dynamic loads.
Simple and user-friendly mounting
The pairs of washers for locking the Lock screw are attached before placement, which prevents failures in the first phase of assembly and facilitates handling.
Lubricant-friendly screw lock washers
The clamping effect is based on the preload force and not on friction, so the anti-rotation lock is guaranteed on dry and lubricated surfaces.
Ecological and corrosion-resistant system
Thanks to their quality surface treatment, Lock screw locking washers are characterized by high corrosion resistance and are entirely free of hexavalent chromium.
