Q:Specific conditions for use of spring washers
A large number of materials in electronic and electrical appliances, carbon, stainless steel, copper alloy etc.. WL type corrugated washer: WL type corrugated washer as a mouth elastic washer, it usually can be installed in a small space, such as to reduce bearing prestress bearing running noise, improve the operation accuracy and stability of bearings. In addition to the electronic appliances also have a large number of applications. Materials are carbon steel, stainless steel, copper alloy, etc.. WN type: WN type wave washers wave washer for multilayer wave overlapping elastic gasket, the series and type WL comparison, because is composed of multilayer material, so in the same compression stroke under the curve of K value is WL gentle, suitable for the whole working stroke and large elastic, elastic and uniform release situation.
Q:Gasket 300HV relative to what material?
For the 140HV level can choose 08F, 08Al and 10, 10F, etc., the surface hardness can reach about 140HV
Q:201 stainless steel gasket and 304 stainless steel gasket which is soft
304 relatively softOur company can produce. Kazakhstan
Q:In the design, the bolt connection is necessary to have a gasket?
Bolted components can not be avoided by extrusion, and a flat gasket reduces the wear of the surface of the component when tightening the bolts, especially those of the aluminum material. In parts when the bolt is tightened by extrusion deformation or broken, the torque control is improper. In the mobile phone production line, a lot of workers to install mobile phones, some people do not tighten tight, some people will break the crack parts, so the production line are used to play the role of measuring torque wrench.
Q:Would like to know the role of flat washer?
Flat washer1 generally used for multiple parts, to increase the bearing surface, covering the larger hole, to prevent damage to the surface of the parts, large washers for wood parts.
Q:How do you choose the appropriate gasket for bolt or screw connection?
When the bolt is connected, the target of the washer is to disperse the material which is connected with the material, reduce the damage to the surface of the material to be connected when the bolt or the nut is reduced, or prevent the loosening of the bolt. When you choose the gasket can be the actual need to relax the use of spring washers, to protect the surface of the material to be connected, optional plain washers. The principle of choice is that the inner diameter of the washer is slightly larger than the outer diameter of the bolt. Screw connection, the use of slightly larger than the location of the largest screw flat washers can be.
Q:How to determine the number of washers
The axial shim changes need to take into account:Disc cleaning frame;After the extreme speed, the angle of the disc flywheel will not fall off the chain: a) in the largest piece of the disc in the disc, the largest piece of flywheel b) chain in the smallest piece of the disc, the flywheel in the smallest piece.
Q:What is the reason why the rubber washer is small after use?
If you do not have any oil around the gasket, which may be used in the process of gasket compression deformation occurred!If there is oil to the present, it is likely that the oil things out of your rubber additives!
Q:What material is used for spring washer
Usually with 65MN spring steel or 70# carbon steel, 3Cr13, also available in stainless steel material SUS304 or SUS316. 65Mn or some other low carbon steel, such as Q235, Q195, etc.
Q:I would like to ask the car transmission inside the thrust washer (thrust washer) is used to do ah?
Differential gear thrust washer is composed of silver alloy pressing, as well as plastics. Planetary gear thrust washer and half axle gear thrust washer shape are concave spherical and planar surface, there are many patterns like grooves or concave point in oil storage. The washer is the role of the friction reducing gear and axial differential housing, improve the transmission efficiency of the differential protection shell, thrust face not excessive wear, to prolong the service life of the differential housing, and maintain the normal meshing and transmission differential gear. The reason for the failure of the thrust washer is a serious lack of lubricating oil, or because of the small size of the stay and the erosion. Planetary gear broken, cross shaft fracture caused by the thrust washer damage, is generally rare. When the vehicle is traveling on a special road, or when the vehicle is in the mud, the differential frequency is used, resulting in excessive wear and thinning of the thrust washer. Thrust washer wear will make gear thrust surface shell, thrust surface acceleration loss, the differential gear axial shift, gear meshing clearance increases, the transmission space increases, causing the gear, cross shaft, differential housing bearing seat hole damage. Thus, the thrust washer is a reliable guarantee of differential action, but also to extend the life of differential parts. To this end, the vehicle should be updated on a regular basis when the thrust washer, to restore its proper clearance, to ensure the normal operation of the differential.
