    摘要： The invention pertains to methods and apparatus for monitoring loads on an arched tubing guide of a coiled tubing injector caused by tension on coiled tubing. The load is sensed by a load sensor, for example, a load cell placed in a strut that supports the arched tubing guide, or in a load pin or load cell placed within the structure arched tubing guide or the connection of the arched tubing guide to a frame for the coiled tubing injector, at a location where the load is representative of the load placed on an arched tubing guide by tension in the coiled tubing. The load sensor generates a feedback signal. The load is monitored, either by an operator or a controller, and torque applied to a reel around which the tubing is wound is adjusted to avoid, or in response to, excessive loads on the arched tubing guide.

    摘要： Systems and methods for measuring cogging torque. An example method includes causing an electric motor to rotate in a positive direction, and for given multiple encoder positions of an encoder, determining a first respective motor winding current applied to the electric motor at the given encoder position. Additionally, the method includes causing the electric motor to rotate in a negative direction, and for the given multiple encoder positions, determining a second respective motor winding current applied to the electric motor at the given encoder position. Further, the method includes, for the given multiple encoder positions, determining a respective cogging torque based on a difference between the first and second respective winding currents. And the method includes storing a cogging torque profile for the electric motor in a database based on the determined respective cogging torque for the given multiple encoder positions.

    摘要： A quick connect and disconnect coupling assembly for coupling a dynamometer to an engine wherein the coupling assembly may be used for both automatic and manual transmission engines. The coupling assembly includes a plurality of circumferentially spaced apart inertia actuated clamping arms which are pivotally attached to a drive member. One end of each clamping arm includes a gear section which is engageable with the engine ring gear and the other end of the clamping arm is operated on by a centrifugal mass assembly which is slidably attached to the drive member. Rotational movement of the drive member results in radial movement of the centrifugal mass assembly for applying a moment force on a respective clamping arm about its rotational axis. In order to prevent excessive clamping force when the engine speed increases, an abutment on the centrifugal mass assembly engages a stop on the drive member for bottoming or stopping the outward radial movement of the centrifugal mass assembly. Further, it has been found that when the effective center of gravity for the clamping arm is substantially coincident with its center of rotation, the clamping force remains virtually unchanged after the centrifugal mass assembly has bottomed out.
