Abstract
The utility model relates to a movable ring transmission device in a cartridge mechanical seal. The device comprises a main shaft, a transmission shaft sleeve, a movable ring and a sealing ring, wherein the transmission shaft sleeve is arranged on the main shaft; the movable ring is connected with the transmission shaft sleeve; and the sealing ring is arranged between the movable ring and the transmission shaft sleeve. The device is characterized in that: a position on the transmission shaft sleeve corresponding to the movable ring is provided with a boss integrated with the transmission shaft sleeve; and the boss is inserted into a movable ring groove. The integrated boss serves as a transmission pin; and due to the adoption of integrated structure, the intensity of the boss having the function of the transmission pin is enhanced and effective transmission between the transmission shaft sleeve and the movable ring is ensured. Therefore, convenient processing and manufacturing, high intensity and long service life are achieved by the adoption of the transmission way; moreover, the device also has the advantages of simple structure, compact space size, capability of ensuring the sealing performance of the entire mechanical seal and the like.
Description
Technical field
The utility model belongs to the mechanical sealing technology field, particularly relates to the rotating ring transmission device in a kind of integrated mechanical sealing.
Background technique
Mechanical seal is a kind of seal arrangement that prevents that working fluid from leaking along running shaft, it is mainly sealed by the sealing surface that stationary ring and rotating ring form, stationary ring is connected with main shaft with equipment respectively by its link with rotating ring, the fitting surface of stationary ring and rotating ring is in the state of fitting tightly all the time in relative rotary course, stop medium to pass through, thereby reach the purpose of sealing.The rotating ring that is sleeved in rotary course on the transmission shaft rotates with main shaft, in order to guarantee the connection between the driving sleeve and rotating ring when rotated, a driving pin is welded in existing main employing on driving sleeve, driving pin is connected with rotating ring, and the driving pin by welding guarantees the servo-actuated between rotating ring and main shaft, the axle sleeve.Because driving pin is subjected to a shearing force all the time in whole rotary course, the long-time use makes the driving pin that is welded on the driving sleeve come off easily, thereby cause rotating ring not rotate with driving sleeve, and then cause the O-ring seals between rotating ring and the driving sleeve impaired, finally cause the leakage of whole mechanical seal, therefore adopt the above-mentioned kind of drive to have deficiencies such as processed complex, intensity is little, working life is short.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, easily manufactured, transmission is effective, rotating ring transmission device in the integrated mechanical sealing of long service life.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Rotating ring transmission device in a kind of integrated mechanical sealing, comprise main shaft, be installed in the seal ring between the driving sleeve on the main shaft, the rotating ring that is connected with driving sleeve and rotating ring and the driving sleeve, it is characterized in that: to be provided with driving sleeve be the boss of one in corresponding rotating ring position on the described driving sleeve, and boss is inserted in the groove of rotating ring.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly to be provided with driving sleeve be the boss of one in corresponding rotating ring position on driving sleeve, boss is inserted in the rotating ring groove, this integral type boss plays the purpose of driving pin, adopt the feasible intensity of integral structure to be strengthened, guarantee the effective transmission between driving sleeve and the rotating ring with boss of driving pin function.Therefore adopt above-mentioned kind of drive convenient processing and manufacture, big, the long service life of intensity; In addition the utility model also have simple in structure, bulk is compact, guarantee the advantages such as sealability of whole mechanical seal.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A sectional view among Fig. 1.
Among the figure: 1, main shaft; 2, driving sleeve; 2-1, boss; 3, rotating ring; 3-1, groove; 4, seal ring.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment:
See also Fig. 1 and Fig. 2, rotating ring transmission device in a kind of integrated mechanical sealing, comprise main shaft 1, be installed in the driving sleeve 2 on the main shaft 1, seal ring 4 between rotating ring 3 that is connected with driving sleeve 2 and rotating ring 3 and the driving sleeve 2, corresponding rotating ring 3 positions are provided with driving sleeve 2 and are the boss 2-1 of one on the described driving sleeve 2, boss 2-1 is inserted in the groove 3-1 of rotating ring 3, this and driving sleeve 2 play the effect of driving torque for the boss 2-1 of one, adopt the feasible intensity of integral structure to be strengthened, guarantee the effective transmission between driving sleeve and the rotating ring with boss of driving pin function.Therefore adopt above-mentioned kind of drive convenient processing and manufacture, big, the long service life of intensity; In addition the utility model also have simple in structure, bulk is compact, guarantee the advantages such as sealability of whole mechanical seal.
