The invention discloses a self-resetting turning mechanism which comprises a hand wheel (1), a rotating shaft (5) and a graduated disc (8), and is characterized in that the hand wheel (1) is fixedly connected onto the top of the rotating shaft (5); the graduated disc (8) is arranged outside the rotating shaft (5) in a sleeving manner, and the rotating shaft (5) can rotate in the graduated disc (8)in a certain angle range; a torsional spring (10) is mounted between a limiting bushing (9) and the rotating shaft (5); the limiting bushing (9) is fixedly connected with the rotating shaft (5), andthe limiting bushing (5) is arranged in the graduated disc (8); spline teeth (14) are arranged at the bottom of the rotating shaft (5); the middle of the hand wheel (1) is fixed on the rotating shaft(5) by virtue of a screw A (2); an internal spline block (3) is arranged on the top of the rotating shaft (5) in a sleeving manner and fixed on the hand wheel (1) by virtue of a screw B (4); and a left extreme position a, a central position b and a right extreme position b are arranged on the graduated disc (8). The self-resetting turning mechanism disclosed by the invention is simple, reliable and flexible and convenient to operate and is suitable for popularization and application of self-resetting turning.
Description
technical field [0001] The invention belongs to the technical field of turning devices, and in particular relates to a self-resetting turning mechanism. Background technique [0002] As one of the most common turning devices, turning handwheels are widely used in aerospace, aviation, military, automobile, machinery and other industries. However, in the traditional aircraft turning system, the turning handwheel cannot be automatically returned to the center. The transmission turning handwheel has the following defects: 1. The structure is complex; 2. It cannot be automatically returned to the center; 3. The parts are processed with high precision and difficulty; 4. The operation is convenient and comfortable. The existence of above-mentioned many problems has influenced the reliability, flexibility and comfort of aircraft cockpit control system to a great extent. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages ...
