Abstract

The invention provides an angle regulating device, which comprises an operating mechanism, a gear transmission mechanism and an operation table. The operating mechanism comprises a first shaft, a handle, a gear disc, an pointer and a dial, wherein the dial is arranged on the operation table, the first shaft is pivotally mounted on the dial, the handle, the gear disc and the pointer are fixedly mounted on the first shaft coaxially, and the pointer is located on one side of the dial which is marked with scales. The gear transmission mechanism is mounted in the operation table and comprises an input shaft provided with a first gear and an output shaft provided with a second gear, wherein the gear disc meshes with the first gear, and the second gear is in transmission meshing with the first gear. Actual rotation angles of a fuel regulating accelerator and / or guide vanes of an engine can be determined accurately with the angle regulating device, thereby facilitating performance analysis of the engine. Meanwhile, the accuracy of the rotation angles is improved by the aid of a fine regulating mechanism arranged additionally, thereby facilitating performance analysis of the engine further.

Description

technical field [0001] The present invention relates to the field of engines, in particular, to an angle adjustment device. Background technique [0002] During the test run of the engine, the angle of the fuel throttle and / or guide vanes should be controlled. At present, flexible shafts are mainly used to realize the angle control of the fuel throttle and / or guide vanes. Specifically, one end of the flexible shaft is connected to the fuel throttle and / or guide vane of the engine located at the test site, and the other end of the flexible shaft extends to the control room and is connected to the mechanical pull rod. The pull rod is connected to an operating handle of the adjusting device, which is pivotally mounted on the gear plate. By operating the operating handle, the operating handle is rotated around the axis of the gear plate by a certain angle, and the operating handle then pulls the pull rod to drive the fuel throttle and / or the guide vane to rotate by a certain a...
