Abstract
The utility model belongs to the technical field of sealing, and particularly relates to a dynamic sealing ring. The related dynamic sealing ring is arranged in a matching groove of the rotating shaft; the sealing ring is a hollow semi-open type; a mass block is arranged in the sealing ring; the mass blocks are uniformly distributed along the circumference; the sealing ring rotates along with the rotating shaft to drive the mass block in the sealing ring to move centrifugally, so that the mass block extrudes the hollow rubber sealing ring to form a dynamic sealing ring. The dynamic sealing ring provided by the utility model is powered by the rotation of the rotating shaft to generate centrifugal force, and the centrifugal force forces the weight to move centrifugally to extrude the hollow rubber sealing ring, so that the dynamic sealing effect is achieved.
Description
Technical Field
The utility model belongs to the technical field of sealing, and particularly relates to a dynamic sealing ring which is arranged on a rotating shaft.
Background
The shaft type apparatus working in the liquid environment is subjected to liquid pressure, and the sealing is particularly important in order to prevent liquid from entering the equipment; such as the propeller of a ship driving its shaft, require good sealing measures; because the rotation speed of the shaft is fast, a common static sealing ring is easy to wear, the sealing effect is reduced, and leakage accidents are easy to happen.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a dynamic sealing ring in order to solve the problems of shaft sealing in the prior art. The utility model adopts the following technical scheme for achieving the purpose:
a dynamic seal ring is arranged in a matching groove of a rotating shaft; the sealing ring is hollow and semi-open; a mass block is arranged in the sealing ring; the mass blocks are uniformly distributed along the circumference; the sealing ring rotates along with the rotating shaft to drive the mass block in the sealing ring to move centrifugally, so that the mass block extrudes the hollow rubber sealing ring to form a dynamic sealing ring.
The sealing ring is a hollow rubber ring.
The dynamic sealing ring provided by the utility model is powered by the rotation of the rotating shaft to generate centrifugal force, and the centrifugal force forces the weight to move centrifugally to extrude the hollow rubber sealing ring, so that the dynamic sealing effect is achieved.

FIG. 4 is a diagram of a weight block in the present application
In the figure: 1. rotation axis, 2, sealing washer, 3, quality piece, 4, cooperation groove.
Detailed Description
The utility model is illustrated in connection with the figures and the embodiments:
as shown in fig. 1, 2, 3 and 4, a dynamic seal ring is mounted in a matching groove 4 of a rotating shaft; the sealing ring 2 is hollow and semi-open; a mass block 3 is arranged in the sealing ring 2; the mass blocks 3 are uniformly distributed along the circumference; the sealing ring 2 rotates along with the rotating shaft 1 to drive the mass block in the sealing ring to move centrifugally, so that the mass block extrudes the hollow rubber sealing ring to form a dynamic sealing ring.
The sealing ring 2 is a hollow rubber ring.
According to the centrifugal sealing ring provided by the utility model, the shaft 1 rotates to provide power to generate centrifugal force, the centrifugal force forces the weight 3 arranged in the hollow rubber sealing ring 2 to move centrifugally, and meanwhile, the hollow rubber sealing ring is extruded, so that the sealing effect is achieved.
Finally, it is noted that the above preferred embodiments are merely intended to illustrate rather than to limit the utility model, and that, although the utility model has been described in detail with reference to the above preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the utility model as defined by the appended claims.
Claims (2)
