Abstract
A hydraulic torque wrench and a method of determining a load exerted on a workpiece by a hydraulic torque wrench. The wrench may generally include a housing; a drive element for engaging the workpiece; a drive actuator for transmitting a torque to the drive element; and a gauge coupled to at least one of the housing and the drive actuator, the gauge being configured to detect a characteristic indicative of a torque exerted by the drive element to the workpiece. The wrench may include a sensor configured to detect rotation of the drive element.
Claims18
A torque wrench operable to exert a torque on a workpiece, the torque wrench comprising:
- a housing;
- a drive element for engaging the workpiece;
- a drive actuator for transmitting a torque to the drive element;
- and
- a gauge configured to detect a bending strain indicative of a torque exerted by the drive element to the workpiece.
A torque wrench operable to exert a torque on a workpiece, the torque wrench comprising:
- a housing;
- a drive element for engaging the workpiece;
- a drive actuator for transmitting a torque to the drive element;
- and
- a gauge configured to detect a reaction force exerted on a reaction member of the housing indicative of a torque exerted by the drive element to the workpiece.
