Wave spring washers.
National standard: GB/T 7246-1987 wavewast is divided into WG-type WL-type WN-type WG-type wavewast: WG-type wavewast is an open-shaped elastic washer, which can usually be installed in a smaller space, such as prestressing bearings, reducing the noise of bearing operation, improving bearing operation accuracy and smoothness. In addition, there are also a large number of application materials in electronic appliances, there are carbon steel, rust-free steel, copper alloy and other WL-type waveform washers: WL-type waveform washers for the shape-of-the-mouth edit, it can usually be installed in a smaller space, such as prestressing bearings, reduce the noise of bearing operation, improve the operating accuracy and smoothness of bearings. In addition, there are also a large number of applications in electronic appliances.
The materials are wnaeths such as carbon steel, stainless steel, copper alloy, etc.: WN-shaped wavewastist is a multi-layer edgy overlapping elastic washer, which is compared to the WL type, because it consists of multi-layered materials, so the K-value curve under the same compression stroke is smoother than the WL type, suitable for greater elasticity, and the entire work stroke elastic release requires more uniform conditions. The materials used are carbon steel, stainless steel, copper alloy, etc.
Disc spring washers.
The disc spring washer, also known as belleville spring washer, was invented by the Frenchman Belleville. The DIN6796 disc spring washer (HDS series) is an anti-loose washer designed for bolt and screw connections. It is designed and manufactured by DIN 6796 for medium or high-strength bolts and screw connections. The large and elastic recovery of the support load makes the HDS series very effective, and the bolt pull can withstand relaxation due to wear, creep, relaxation, thermal expansion, contraction, or seal compression of consumables.
The HDS series increases the elasticity of the screw several times, it can effectively replace the ordinary spring washers, but not for locking washers, flat washer combination. Since the HDS series is a disc spring that can be combined or folded. The combination of the combined method increases the deformation of the disc reed group, and the stacking method combination increases the spring force of the reed group. The ideal installation is as flat as possible, the closer to the leveling state, the faster the tension moment increases, no torque wrench is required, the appropriate bolt pull can be.
