  • Patent number: 9593992
    Abstract: A torque detecting system is adapted to detect a setting torque of a torque providing apparatus. A torque driving apparatus is mounted on a stationary base to exert a resisting force on the torque providing apparatus. The setting torque of the torque providing apparatus corresponds to the resisting force. The torque detecting system comprises an angle detecting module and an operation device. The angle detecting module is mounted on the torque driving apparatus and outputs a detecting voltage. The operation device obtains a torque value via table-searching based on the detecting voltage. The torque value corresponds to the setting torque of the torque providing apparatus. The torque detecting system performs the torque detection through a non-contact detecting technique, such that detecting accuracy would not be affected after long term use.

The torque adjustment device can vary a torsional drag force exerted by a torque-applying device on a torque generation mechanism. The torque measurement device can detect a displacement or rotational angle variation of the torque-applying device. The torque calculation device further precisely converts the displacement or rotational angle variation provided by the torque measurement device into a corresponding torque value. Being a systematic integration of the torque adjustment device, the torque measurement device and the torque calculation device allows the torque adjustment and measurement system to be applied to the field of fitness equipment for users to adjust torque setting of fitness equipment and precisely measure and acquire the torque value.
