Description

A two-piece sealing strip

technical field

The utility model relates to a sealing strip, in particular to a two-piece sealing strip.

Background technique

The sealing strip is used in the variable phaser and is installed between the rotor (rotor) and the stator (stator). The previous design of the sealing strip is a single piece. The support in the sealing strip is elastic and made of rubber. It is directly cast on the Inner cavity of the sealing strip. The following problems exist in the use of a single-piece sealing strip: (1) the processing process of the single-piece sealing strip is complicated; (2) the cost of the single-piece sealing strip is relatively high.

Utility model content

The purpose of this utility model is to provide a two-piece sealing strip with simple installation process and low cost in order to overcome the above-mentioned defects in the prior art.

The purpose of this utility model can be achieved through the following technical solutions:

A two-piece sealing strip, characterized in that the sealing strip is arranged between the stator and the rotor of the variable phase device, the sealing strip is composed of a spring and a sealing body, the sealing body is a semi-frame structure, and the sealing body A groove is arranged on the outer side of the sealing body, and the spring is arranged in the groove of the sealing body.

The spring has an arc-shaped structure, and its two ends are clamped on the two ends of the groove of the sealing body, and the top of the arc abuts against the surface of the stator or rotor outside the sealing strip.

The inner side of the sealing body abuts against the surface of the rotor or the stator.

The sealing body is made of plastic, and the spring is made of metal.

Compared with the prior art, the utility model is installed between the stator and the rotor, the installation process is simple, and the cost is also low.
