发明名称 Controllable Mechanical Transmission For Downhole Applications
摘要 A transmission for rotatably coupling an input shaft with an output shaft about a longitudinal axis is disclosed, which may include a continuous variable transmission and an output torque sensing control mechanism. The continuous variable transmission may be a toroidal disc continuous variable transmission. The output torque sensing control mechanism may include a spring and an intermediary output shaft rotatably connected with an output rotating member of the continuous variable transmission, and the output shaft may be externally threaded and matable with an internally threaded portion of the intermediary output shaft.
