How rotary face does its transmission

Spring interference transmission: Both ends of spring are installed on spring seat and rotary face with interference, and do transmission by making use of the feature of smaller and smaller inner diameter as a result of spring rotating along the helical direction. This transmission mode is characterized by simple structure and mere transmitted in one direction.

Spring hook transmission: Both ends of spring are respectively hooked to spring seat and rotary face for transmission. This transmission mode is characterized by  compact structure，reliable work and mere transmission in one direction.

Lug, fork transmission: By making use of concave and convex type of metals, it is suitable for complex structures. When there is relative axial movement, it can ensure reliability of transmission and allow mechanical seal to have a larger deflection.

Bellows transmission: direct transmission using bellows.

Drive screw transmission：By making use of screws，this transmission mode is commonly used in multi-spring structures.
