Abstract
A screwing equipment that comprises at least one rotary member mounted in a tool body and capable of producing at least one vibrational frequency representing a wear condition of said rotary member(s). Such screwing equipment further comprises means for measuring said vibrational frequencies designed to communicate with means for processing, said measurement enabling same to be compared to at least one reference frequency in order to determine said wear condition.
Claims6
A screwing tool including at least one rotary member selected from the group consisting of a motor, a bell crank member, a gear member, and combinations thereof, said rotary member(s) being mounted in a tool body and being capable of producing at least one vibration frequency representing a condition of wear of said rotary member(s),
- characterised in that the screwing tool comprises processing means including means for storing a reference frequency relative to each of said rotary member(s), and means for measuring said vibration frequency or frequencies and configured to communicate with said means for processing said measurement, making it possible to compare said processed measurement with at least one reference frequency so as to determine the condition of wear, wherein said rotary member(s) are intended to produce a tightening torque, with said measurement means including at least means for measuring said torque.
