Abstract
The utility model discloses a mechanical sealing ring. The mechanical sealing ring comprises a main sealing ring. Annular spring grooves are respectively formed in the upper end surface of the main sealing ring and the lower end surface of the main sealing ring. Clamping spring rings are installed in the annular spring grooves. A buffering ring is installed on the outer wall of the main sealing ring. The buffering ring and the main sealing ring are bonded through mucilage glue. A plurality of buffering holes are formed in the outer wall of the buffering ring. A sealing main lip is installed on the inner wall of the main sealing ring. The mechanical sealing ring is simple in structure and reasonable in design. The clamping spring rings are installed inside the annular spring grooves so that requirements to self electricity of the main sealing ring are reduced. External force impact is reduced and service life of a whole body can be prolonged by that the buffering ring is installed on the outer wall of the main sealing ring. The installation of the sealing main lip can enhance enclasping force of the sealing ring to a shaft, wherein the shaft is located inside the sealing ring.
Description
Technical field
The utility model relates to field of mechanical technique, relates in particular to a kind of mechanical seal ring.
Background technique
In the prior art, the seal ring that shaft sealer uses generally adopts the O RunddichtringO, the O RunddichtringO produces prestressing force by the extrusion-deformation of when assembling and reaches sealing effect, its simple in structure, withstand voltage height, volume are little, but it is large to wear and tear in movement process due to seal ring, and being in for a long time deformation state, elasticity can not keep for a long time, and then causes shorten working life.Cause bad impact for normal production.
The model utility content
For the problem that above-mentioned prior art exists, the utility model provides a kind of mechanical seal ring.
To achieve these goals, the technical solution adopted in the utility model is: a kind of mechanical seal ring, comprise main seal ring, and the both ends of the surface up and down of main seal ring have the annular spring groove, are provided with the lock ring spring ring in the annular spring groove; The main seal ring outer wall is provided with buffer ring, and bonding by viscose glue between buffer ring and main seal ring, the outer wall of buffer ring is provided with several cushion holes; The inwall of main seal ring is provided with the main lip of sealing.
As preferably, the sectional shape of described annular spring groove is rectangle, trapezoidal or oval.
As preferably, the height of described buffer ring is identical with the height of main seal ring.
Compared with prior art, the utility model has the advantage of: simple in structure, reasonable in design, be provided with the lock ring spring ring in the annular spring groove, can reduce the flexible requirement of primary seal circle self, the primary seal ring outer wall is provided with buffer ring, can reduce the impact of external force, make bulk life time extend; Seal arranging of main lip and strengthened the enclasping force of seal ring contraposition axle in the inner.
