摘要： Embodiments disclosed herein provide a ratchet assembly having a ratchet nut, a shaft at least partially disposed within the ratchet nut and a first and second pawl disposed within the ratchet nut and supported by the shaft. The first and second pawls are movable along a common central axis. The assembly further includes a biasing mechanism, the biasing mechanism biasing the first and second pawls in an engaged position to maintain contact with the ratchet nut to prevent relative rotation between the shaft and the ratchet nut. The assembly also includes an alignment pin extending at least partially within the first and second pawls to maintain alignment and to facilitate movement of the pawls along the common central axis.

摘要： A wellhead assembly is provided including a casing and a tubular member mounted over the casing. A flange extends from the tubular member. A generally elongated annular member is provided in the tubular member. The generally elongated annular member has a first end portion above the tubular member and second end portion below the first end portion. A hanger may be suspended within the tubular member. In such case, a seal may be formed between the elongate annular member and the hanger.
