  • SHEAR COUPLING ASSEMBLY WITH BACKOFF PREVENTION
    Publication number: 20090271966
    Abstract: A shear coupling assembly utilizes a novel pin coupling member having radial slots formed about a top portion of the insert member, the top portion being radially expandable once engaged in the box coupling member to lockingly engage the threaded connection. Locking of the insert member in the box coupling member prevents backing-off of the connection and maintains a pretension in the neck of the pin coupling member, during use. The top portion of the insert can be radially expanded by forcing a ball bearing into a counterbore formed in the insert member.
