Description

Mechanical seal convenient to disassemble

Technical Field

The utility model belongs to the technical field of sealing parts, relates to a mechanical seal, and in particular relates to a mechanical seal convenient to detach.

Background

Mechanical seals are typically composed of moving rings, stationary rings, springs, bushings, and the like. The movable ring and the static ring are main components of the seal, and the spring applies pressure through the shaft sleeve to enable the movable ring and the static ring to be in close contact, so that the sealing effect is achieved, the mechanical seal is commonly used in a machine rotating at a high speed, and therefore good friction force is required to keep working stability.

Conventional mechanical seals generally fasten the ring by means of a sleeve made of elastic material and are fixed on the transmission shaft by means of the elasticity of the sleeve, but the wear resistance and impact strength of the elastic material are limited.

The utility model aims to solve the problems in the prior art and provides a mechanical seal with high tightness and convenient disassembly.

The aim of the utility model can be achieved by the following technical scheme: the utility model provides a dismantle simple and convenient mechanical seal, includes moving ring subassembly and quiet ring subassembly, its characterized in that, the moving ring be equipped with and be fixed in epaxial axle sleeve of transmission, and this axle sleeve one end is the butt joint end, and offered the joint annular on this butt joint end terminal surface, be located the joint annular in be provided with the moving ring, be located offer the ring channel on the butt joint end inner wall, and be equipped with the O type circle in this ring channel, quiet ring subassembly on be equipped with the quiet ring of contradicting with the moving ring.

The mechanical seal is simple and convenient to detach, the other end of the shaft sleeve is a fixed end, and a waterproof ring is arranged on the inner wall of the fixed end.

The mechanical seal is simple and convenient to detach, the protection covers are arranged on the outer walls of the fixed end and the butt joint end, and a supporting spring for supporting is arranged between the two protection covers.

The mechanical seal is simple and convenient to detach, and the inner wall of the butt joint end is also provided with an installation chamfer.

The mechanical seal is simple and convenient to detach, the movable ring is provided with the mounting nail, and the mounting nail is provided with the shrinkage groove.

Compared with the prior art, the O-shaped ring is fixed by extrusion deformation of the extrusion shaft sleeve when the mechanical seal is installed through the movable ring, so that the O-shaped ring is installed more tightly, the waterproof effect of the mechanical seal is higher due to the O-shaped ring and the waterproof ring, the protective cover enables the two ends of the shaft sleeve to have higher impact resistance effect, and the supporting spring can be further enabled when the service life is prolonged.
