The invention provides a mechanical sealing mechanism of a corrugated spring, which comprises a flange fixed with a shaft sleeve, a fixed sealing sleeve arranged between the flange and the shaft sleeve and a rotary sealing sleeve for realizing sealing with the end surface of the fixed sealing sleeve, wherein the end surface of the rotary sealing sleeve far away from the fixed sealing sleeve is connected with an elastic pressing mechanism, and the elastic pressing mechanism comprises a limiting ring fixed with the shaft sleeve and a corrugated spring arranged between the limiting ring and the end surface of the rotary sealing sleeve.
Preferably, the corrugated spring is sleeved with a pushing ring close to the end of the rotating sealing sleeve, and the pushing ring is fixedly connected with the rotating sealing sleeve.
Preferably, the push ring is connected with the rotary sealing sleeve through a pin shaft, and the axis of the pin shaft is parallel to the axis direction of the shaft sleeve.
Preferably, the pushing ring is provided with a sleeve near the end of the corrugated spring, and the corrugated spring is sleeved outside the sleeve near the end of the pushing ring.
Preferably, the end of the limit ring close to the corrugated spring is provided with an outer sleeve, and the end of the corrugated spring close to the limit ring is sleeved in the outer sleeve.
The mechanical sealing mechanism for the corrugated spring in the technical scheme of the invention has the beneficial effects that:
1. the elastic pressing mechanism is used for pressing the rotary sealing sleeve, so that the rotary sealing sleeve rotates along the end face of the fixed sealing sleeve when rotating along with the shaft sleeve, the sealing effect is improved, friction generated in the sealing process is reduced, and the service lives of the rotary sealing sleeve and the fixed sealing sleeve are prolonged.
2. The arrangement of the sleeve and the outer sleeve is convenient for fixing the corrugated spring, and the spring can not be twisted except for compression in the rotation process of the elastic pressing mechanism.

Fig. 1 is a schematic view of a mechanical sealing mechanism of a corrugated spring according to the technical solution of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
As shown in fig. 1, the mechanical seal mechanism of the corrugated spring in the technical scheme of the present invention includes a flange 2 fixed with a shaft sleeve 1, a fixed seal sleeve 3 disposed between the flange 2 and the shaft sleeve 1, and a rotary seal sleeve 4 sealed with an end face of the fixed seal sleeve 3. An elastic pressing mechanism is connected on the end face of the rotary sealing sleeve 4 far away from the fixed sealing sleeve 3. The elastic pressing mechanism comprises a limiting ring 5 fixed with the shaft sleeve 1 and a corrugated spring 6 arranged between the limiting ring 5 and the end face of the rotary sealing sleeve 4.
Based on above-mentioned technical scheme, utilize elasticity hold-down mechanism to realize compressing tightly the rotating seal cover, after rotating seal cover 4 contacts on the terminal surface of fixed seal cover 3, rotating seal cover 4 is driven rotatoryly by the axle sleeve under the effect of elasticity hold-down mechanism for the terminal surface that fixed seal cover 3 and rotating seal cover 4 contacted rotates relatively, produces sliding friction, is convenient for the sealed of fixed seal cover 3 and rotating seal cover 4 on the one hand, on the other hand prolongs the life of fixed seal cover 3 and rotating seal cover 4.
In the technical scheme, the corrugated spring 6 is sleeved with a push ring 9 near the end of the rotary sealing sleeve 4, and the push ring 9 is fixedly connected with the rotary sealing sleeve 4. The pushing ring 9 is connected with the rotary sealing sleeve 4 through a pin shaft 10, and the axis of the pin shaft 10 is parallel to the axis direction of the shaft sleeve 1. The design of this mechanism for propelling movement ring 9 realizes pushing in step rotating seal cover 4, avoids at the axle sleeve rotation axis, and the slippage appears in rotating seal cover 4 and not with the problem of axle sleeve 1 synchronous revolution.
In the technical scheme, the end, close to the corrugated spring 6, of the pushing ring 9 is provided with the sleeve 8, and the end, close to the pushing ring 9, of the corrugated spring 6 is sleeved outside the sleeve 8. The end of the limit ring 5 close to the corrugated spring 6 is provided with an outer sleeve 7, and the end of the corrugated spring 6 close to the limit ring 5 is sleeved in the outer sleeve 7. The design of this structure realizes that 6 both ends of ripple spring are spacing, and ripple spring 6 is only compressed at sealed in-process, can not produce deformation such as bending.
It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by one of ordinary skill in the art and related arts based on the embodiments of the present invention without any creative effort, shall fall within the protection scope of the present invention. Structures, devices, and methods of operation not specifically described or illustrated herein are generally practiced in the art without specific recitation or limitation.
