Abstract
The invention discloses a driving structure of a rotating ring for a mechanical seal, which comprises a drive sleeve, the rotating ring and a round key. The drive sleeve and the rotating ring are sleeved on a shaft sequentially, an extending end of the drive sleeve is sleeved on the outer side of the rotating ring, and the rotating ring is connected with the extending end of the drive sleeve. The driving structure has the advantages that stability and high reliability of dimple driving are achieved, while defects of deformation and low dimension precision in dimpling of the drive sleeve are overcome, technical requirements for machining are lowered, and machining cost is reduced. Further, the round key cannot fall off even when being loosened from the fixed joint of the drive sleeve, and accordingly reliability in running is guaranteed.
Description
Technical field
The present invention relates to the mechanical sealing technology field, be specifically related to a kind of mechanical seal rotating ring driving structure.
Background technique
The traditional mechanical seal drive sleeve and the rotating ring kind of drive mainly are that cylindrical at the drive sleeve external part is directly towards nest; Cooperate with the recess of rotating ring and to carry out transmission; But directly drive sleeve is prone to cause the drive sleeve distortion towards nest, not high towards the nest dimensional accuracy, therefore require very high to processing technique.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of mechanical seal rotating ring driving structure is provided.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of mechanical seal rotating ring driving structure; Comprise drive sleeve, rotating ring, round key; Said drive sleeve and rotating ring are sleeved on the axle successively; And the external part of said drive sleeve is sleeved on the outside of rotating ring, and said rotating ring is connected with the external part of drive sleeve through round key.
Said round key is the stepped shaft cylinder, and its top cylindrical radius is less than the lower circumference radius, and the top cylinder of said round key assigns on the through hole of external part of said drive sleeve, and the lower cylindrical of said round key is installed in the driving groove of said rotating ring.
Characteristics of the present invention are: have towards nest stable drive, reliability high in; The shortcoming yielding when having overcome drive sleeve, that dimensional accuracy is not high towards nest; Reduced the processing technique requirement, also reduced simultaneously processing cost, even and round key become flexible with drive sleeve bearing; Round key can not deviate from yet, and has guaranteed the reliability of run duration.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the local A place enlarged view of Fig. 1;
Fig. 3 is a round key structural representation of the present invention.
Wherein: 1, drive sleeve 2, spring 3, throw-out collar 4, rotating ring 5, round key 6, stationary ring 7, through hole 8, driving groove.
Embodiment
Shown in Fig. 1-3, mechanical seal is made up of the drive sleeve 1, spring 2, throw-out collar 3, rotating ring 4, the stationary ring 6 that are sleeved on successively on the axle, and the external part of said drive sleeve 1 is sleeved on the outside of spring 2, throw-out collar 3, rotating ring 4; And the external part of said drive sleeve 1 is connected through round key 5 with said rotating ring 4, is used for towards through hole 7 of position processing of nest driving groove 8 of position processing of said rotating ring 4 corresponding through holes 7 originally at the external part of said drive sleeve 1; Said round key 5 is the stepped shaft cylinder, and its top cylindrical radius is less than the lower circumference radius, and the top cylinder of said round key 5 assigns in the said through hole 7; And round key 5 tops are struck out turbination; Make round key 5 and drive sleeve 1 transition fit, guarantee that round key 5 is fixed on the drive sleeve 1, the lower cylindrical with said round key 5 is installed in just transmission smoothly in the said driving groove 8 then; Before rotating ring 4 takes out; Even round key 5 is loosening with the bearing of drive sleeve 1, round key 5 can not deviate from yet, and guarantees the reliability of run duration.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
