    Z19B type expansion joint sleeve

    description:The structure of the Z19B type expansion joint sleeve can be made into a variety of styles.According to the installation load, multiple expansion sleeves can also be used in series.It has the advantages of dispersing stress concentration, strength and avoiding shaft disconnection.
    Detailed introduction:

    Z19B typeExpansion coupling sleeveThe structure can be made into a variety of styles.According to the installation load, multiple expansion sleeves can also be used in series.It has the advantages of dispersing stress concentration, strength and avoiding shaft disconnection.

    Technical points of Z19B type expansion coupling sleeve:

    Between the outer ring and the inner ring is an inner and outer pressure ring. The outer walls of the inner and outer pressure rings are sloped, and the bottom of the second ring is opposite. The inner wall of the outer ring and the outer wall of the inner ring are convex, and the concave shape of the outer wall of the pressure ring is mutually opposite. Compensation, there are gaps on the inner and outer rings.When the bolts are tightened, the inner and outer pressures move relative to each other. Under the action of the inclined plane, the inner ring begins to shrink, and the outer ring begins to expand outward, achieving the purpose of connecting the shaft and the hub.It has the advantages of dispersing stress concentration, strength, and avoiding shaft disconnection.It is suitable for use when connecting shafts and hubs.
