Threaded member capable of detecting tension

摘要

A threaded member has an axial direction. A thread is formed on the threaded member in the axial direction. At least one receiving recess is formed on a circumferential surface of the thread of the threaded member. At least one sensor member is disposed in the receiving recess for detecting tension applied to the threaded member in the axial direction. When a tightened article is tightened by the threaded member, an extension force/tension is applied to the threaded member in the axial direction. The sensor member is positioned in adjacency to the thread of the threaded member so that the sensor member can precisely detect the extension extent of the threaded member for precisely obtaining the tightening force applied to the threaded member.

1. A threaded member capable of detecting tension, the threaded member having an axial direction, a thread being formed on the threaded member in the axial direction of the threaded member; the threaded member comprising:
at least one receiving recess formed on a circumferential surface of the thread of the threaded member, the thread of the threaded member being located on an outer perimeter of each of the at least one receiving recess; and at least one sensor member correspondingly fixed in the receiving recess for directly detecting tension applied to the threaded member in the axial direction; wherein the sensor member has an extension element and a sensor, the extension element of the sensor being directly connected to a wall face of the receiving recess and the thread of the threaded member being located on an outer perimeter of each of the at least one sensor member and the sensor member directly detecting tension applied to the threaded member, the sensor being located on the extension element; wherein two opposing ends of the extension element are fixedly connected to the wall face of the receiving recess in the axial direction of the threaded member.
