SPINDLE MOUNTED TELEMETRY SYSTEM

摘要

The present invention relates to a telemetry assembly (18; 200; 220) for a spindle (14). The telemetry assembly (18; 200; 220) includes a wireless transmitter (49; 146; 206; 226; 228) coupled to the spindle (14) to rotate therewith and a receiving antenna (51; 148; 208; 226; 228) wirelessly coupled to the transmitter (49; 146; 206; 226; 228). A guiding system (172; 150) having a central aperture (21; 201; 221) and coupled to the wireless transmitter (49; 146; 206; 226; 228) and the receiving antenna (51; 148; 208; 226; 228) guides rotation of the wireless transmitter (49; 146; 206; 226; 228) relative to the receiving antenna (51; 148; 208; 226; 228). If desired, the telemetry assembly (18; 200; 220) can be used in a telemetry system (10) including a hub adapter (22) mountable to the hub adapter (22). Furthermore, an angular positioning device (58; 64; 156) and a wireless power coupling (54) can be provided.
