Abstract

The invention discloses a driving device for mechanical seal, which is guaranteed in material, convenient in manufacture, stable in structure and tighter in combination. The driving device mainly comprises a spring seat, a driving seat, a moving ring and a fixing ring, a spring is arranged between the spring seat and the driving seat, a groove is arranged between the spring seat and the driving seat, a convex fork is arranged between the driving seat and the moving ring, and the groove and the fork are mutually engaged to drive. The driving device is mainly used in mechanical seal.

Description

technical field [0001] The invention relates to a mechanical seal, in particular to a transmission device between a spring seat, a transmission seat and a moving ring in the mechanical seal. Background technique [0002] Mechanical seals are widely used in the mechanical industry. A commonly used mechanical seal structure mainly includes: spring seat, transmission seat, moving ring and static ring. There is a spring between the spring seat and the transmission seat; when working, the spring seat and the transmission Between the seats, between the transmission seat and the moving ring, the transmission is carried out through additionally provided pins. The disadvantage of this transmission structure is: on the one hand, because the material of the pin is difficult to guarantee, it is easy to be corroded; Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a transmission device in a mechanical seal with guaranteed mat...
