Inclined coil spring: inclined coil spring contact finger sealing characteristics


Release time:

2021-09-16

Inclined spring: Mechanical seal is a safe and reliable sealing form, which is widely used in fluid sealing. In the sealing process, it does not directly contact with the rotating shaft to cause wear, so it can obtain a better sealing effect, reduce leakage, and improve the safety and reliability of the machine. The mechanical seal structure of the inclined oblique ring spring uses the inclined oblique ring spring as the elastic compensation element of the mechanical seal, and uses the characteristics of large elastic deformation and small elastic change of the inclined oblique ring spring to make the mechanical seal obtain better sealing effect.

In some special occasions, such as high temperature, high pressure, high speed and other mechanical seal conditions, the performance of ordinary cylindrical compression coil spring mechanical seal is difficult to meet the requirements. In order to meet the needs of modern mass production, the production of an axial end contact mechanical seal spring, namely oblique ring spring, also known as spring finger contact and finger contact spring. The main feature of the inclined inclined coil spring is to use an axially compressed annular inclined coil spring as a compensation element instead of the traditional spring-pushed mechanical seal. During compression, each coil of the canted coil spring coils acts in parallel, compresses in the axial direction, and produces a rotational movement in the circumferential direction. The mechanical seal of this structure relies on the elastic force provided by the inclined coil spring to push away the axial sliding of the static ring, compensate for the axial position deviation caused by wear, and can also buffer the vibration and pressure changes under complex working conditions. Therefore, the balance of the axial force between the sealing pairs is maintained, a better and more stable sealing film is formed between the sealing friction pairs, and a dynamic seal is realized under the pressure of the sealing film itself.

Structural features of spiral coil spring:

The coil size of the inclined coil spring is smaller, the coil is more, and its current capacity and technical economy are higher. In the case of large tolerance deviation, the inclined inclined coil spring can still maintain constant force, which can reduce the deformation of the spring and compensate the influence of surface unevenness and joint tolerance to a large extent. In addition, the inclined coil spring can also withstand a certain compression deformation, so that it can work normally under harsh working environments such as vibration and impact.

According to obliqueinclined coil springThe different structural characteristics of the oblique coil spring can be divided into radial and axial two types. The direction of the compression force of the radially inclined canted coil spring is perpendicular to the center line (along the radius of the circle). This spring is mainly used in connectors. The compression force of the axial oblique coil spring is parallel to the center line (in the direction of the circle), and this spring is generally used as a seal.
