What Does the Gasket do?

 As a Tension Clamp China Supplier, share with you. We often see in mechanical equipment that some bolt connections use washers, some bolt connections do not use washers, some bolt connections use flat washers, some use spring washers, and some use spring washers. Add flat washers.

Should we use washers when designing? It's so entangled, have you ever entangled like this.

Flat Washers

When the bolts need to be removed frequently, in order to protect the surface of the connected part from being scratched, it is generally necessary to place a flat washer at the position of the nut or bolt head, so as to prevent the surface of the connected part from being scratched, especially for the use of precision Machined surface.

In some joints where the friction coefficient is required to be more precise, there is no separate test requirement for the friction coefficient. For example, in the wind power bolt connection, bolts, nuts, and washers are generally purchased.

In this case, the bolts, nuts, and washers are all provided by the same manufacturer. The bolt manufacturer needs to deal with the nuts and washers accordingly to ensure that the coefficient of friction between the nuts and washers remains consistent. At the same time, the supplier is required to test the torque coefficient to meet the technical requirements.

When the bolt strength is relatively high, the allowable compressive stress of the connected parts is relatively low. For example, nowadays, the requirements for lightweight cars are getting higher and higher. In the body and even the chassis structural parts, a large number of lightweight connection technologies and structures are used to reduce the compressive stress of the pressure-bearing surface of the connected parts in the bolted joints and prevent crushing. And permanent plastic deformation, generally need to add flat washers.

In addition, in the bolt connection, the pressure transmission of the pressure bearing surface of the bolt head or nut is gradually expanded in a trumpet shape. The larger the pressure bearing surface, the smaller the compressive stress. Therefore, the addition of a flat washer can reduce the pressure on the contact surface of the connected part. Stress to ensure the effectiveness of the bolt connection.

For connections that need to be sealed, the stress distribution diameter of the stress cone on the joint surface is increased. In this way, adding a gasket can ensure the sealing effect.

Our company also has Rail Anchor Bolt on sale, welcome to contact us.

Tension Clamp Is Important

图片
With the increase of the axle load of the railway locomotive and the improvement of the running speed of the train, as well as the development of the urban rail transit and the subway, the Tension Clamp  is also becoming a key link in the continuous development of the track structure, which is concerned by all the countries. In the general line, the need is about buckle pressure, good elastic spring, to meet the needs of heavy-duty, high-speed lines, while in the viaduct track seamless circuit, in order to reduce the interaction between the rail and the bridge, we have to ensure the elasticity that is enough, if the train goes through, the loss of undercover cushion due to compression caused by the buckle pressure is small, and fasteners of  Railway Fastening System  do not loose. Although it is a small public work device, but it is an important part of the track, because of its large demand, about 7000 per kilometer, its reliability is directly related to the safety...

Pay Attention to Rail Plate Base Pad

图片
As an indispensable part of the railway, the  Rail Plate Base Pad  plays an important role on the railway. If it falls off, which will influence the whole  Railway Fastening System  deeply. In the high-speed railway subgrade, the separation of the slab Rail Plate Base Pad will reduce the track strength. This situation means the stiffness and service life of the track will be reduced directly. It causes the rail plate base pad to crack and disconnects from the lug time. The pressure of the top surface of subgrade increases with the length of abscission. Meanwhile, the trend of increasing is becoming more and more obvious.

Do You Know Heavy Haul Rail?

图片
The first International Heavy Haul Congress in 1978 was held in Perth, Australia. Since the establishment of the International Association of Heavy Haul Transport in 1985, the definition of heavy railroads has evolved with heavy loads and advancing with the time. In 2005, the International Association of Heavy Load Associations proposed a new heavy haul railway standard that required to meet at least two of the following three conditions: 1.train traction quality is not less than 8000t 2.vehicle axle in the vehicle reach or exceed 27t 3.The length of the line is not less than 150 km, the annual freight volume is not less than 40 million tons. We support several types of  Rail Fastening System  to meet the different rail's requirements.
