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
The present invention relates to a kind of mechanical seal, refer more particularly to be hit by a bullet transmission device between spring abutment, retainer and the rotating ring of mechanical seal.
Background technique
Mechanical seal is widely used in the mechanical industry, and the structure of a kind of mechanical seal commonly used mainly comprises: spring seat, retainer, rotating ring and stationary ring are provided with spring between spring seat and the retainer; During work, between spring seat and the retainer, between retainer and the rotating ring respectively the pin by other setting come transmission.The shortcoming of this drive mechanism is: because the material of pin is difficult to assurance, be corroded easily on the one hand; Owing to reasons such as machining accuracies, the fit dimension between pin and each component is difficult for grasping on the other hand, and pin comes off easily.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of material to be guaranteed and easily manufactured, sound construction, in conjunction with the transmission device in the mechanical seal of close-fitting more.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of transmission device that is used for mechanical seal, mainly comprise: spring seat, retainer, rotating ring and stationary ring, be provided with spring between spring seat and the retainer, between spring seat and the retainer and the groove and the protruding fork that are respectively arranged with the transmission that cooperatively interacts between retainer and the rotating ring.
The groove of the above-mentioned transmission that can cooperatively interact and a kind of concrete structure of protruding fork are: be respectively arranged with the protruding fork that fuses with retainer at the two ends of retainer, be respectively arranged with the groove that the protruding fork that is adjacent matches on spring seat and rotating ring.
Offer pin-and-hole in the groove of above-mentioned spring seat.
The invention has the beneficial effects as follows: because the transmission between the transmission component in the mechanical seal no longer relies on additional pin to come transmission, but rely on the protruding fork and the groove that are arranged on the transmission component body, cooperatively interact to come transmission, like this sound construction is set, be convenient to processing, thereby the material of transmission device and machining accuracy can both well be guaranteed, have fundamentally solved the caducous problem of pin.

Embodiment
The invention will be further described below in conjunction with accompanying drawing, but the present invention should not only limit to this embodiment.
As shown in Figure 1, a kind of transmission device that is used for mechanical seal comprises: be installed in spring seat 1, retainer 2, rotating ring 4 and stationary ring 5 on the transmission shaft 6 successively; Spring seat 1 is fixedlyed connected with transmission shaft 6, offers cavity 13 on the spring seat 1---and referring to Fig. 2, shown in Figure 3, an end of spring 3 is pressed on the bottom of cavity 13, and the other end of spring 3 compresses retainer 2; Retainer 2 is provided with protruding fork 21 and protruding fork 22---referring to shown in Figure 5, also offer the groove 11 that matches with protruding fork 21 on the retainer 2 on the spring seat 1---referring to Fig. 2, shown in Figure 3, offer the groove 41 that matches with protruding fork 22 on the retainer 2 on the rotating ring 4---referring to shown in Figure 6; Protruding fork 21 on the retainer 2 extend in the groove 11 on the spring seat 1, and the protruding fork 22 of another in the retainer 2 extend in the groove 41 on the rotating ring.In addition, also offer the pin-and-hole 12 that is used for the installing and locating pin in the groove 11 on spring seat 1---referring to shown in Figure 3, adapt with it, offer the slotted hole 23-that matches with locating stud in the protruding fork 21 on retainer 2 referring to shown in Figure 5.During work, rotatingshaft 6 drives the spring seat 1 that fixes with it and rotates, and spring seat 1 drives retainer 2 by groove 11 protruding forks 21 again and rotates, and 2 of retainers drive rotating ring by protruding fork 22 and groove 41 and rotate, and realize the purpose of transmission.
Claims (3)
