Let's talk about the contact and sealing characteristics of the oblique coil spring, let's talk about the precision spring of Chuangyecheng

Oblique coil spring: Mechanical seal is a safe and reliable sealing form widely used in fluid sealing. During the sealing process, it will not directly contact the shaft and cause wear, thus achieving better sealing effect, reducing leakage, and improving the safety and reliability of the machine. The mechanical seal structure of the inclined coil spring uses the inclined coil spring as the elastic compensation element of the mechanical seal. The inclined ring spring has the characteristics of large elastic deformation and small elastic change, which enables mechanical seals to achieve good sealing effect.

In some special occasions, such as high temperature, high pressure, high speed and other mechanical sealing conditions, the performance of ordinary cylindrical compression inclined ring spring mechanical seals is difficult to meet the requirements. In order to meet the needs of modern mass production, a type of axial end contact mechanical seal spring, namely inclined coil spring, also known as finger contact spring and finger contact spring, has been produced. The main feature of the oblique coil spring is the use of an annular oblique coil spring with axial pressure as a compensation element, replacing the traditional spring push mechanical seal. During the compression process, each coil in the inclined coil spring acts in parallel, compresses axially, and generates rotational motion along the circumference. The mechanical seal of this structure relies on the elastic force provided by the inclined inclined ring spring to drive the axial sliding of the moving ring, compensate for the axial position deviation caused by wear, and buffer the vibration and pressure changes under complex working conditions. In order to maintain the balance of axial force between the sealing pairs, a better and more stable sealing film is formed between the sealing friction pairs, and dynamic sealing is achieved under the pressure of the sealing film itself.

According to the different structural characteristics of the swashplate spring, it can be divided into radial and axial types. The compression force of the radial inclined coil spring is perpendicular to the centerline (along the radius of the circle). This spring is mainly used for connectors. Axially inclined coil springs have a compressive force parallel to the centerline (in the circumferential direction) and are generally used as seals.
