Abstract

The invention provides a quantitative analysis experiment device of an influence rule on tooth surface friction force by torsional vibration of a shaft system. A motor (1) is installed on a base (14), an output shaft of the motor (1) is connected with one end of a shaft (5) through a cardan joint assembly (2) and the shaft (5) is supported by a front bearing assembly and a rear bearing assembly. A rolling disc (11) is fixed on the shaft (5) and is in contact with a friction sheet (10). The friction sheet (10) is arranged on a friction sheet supporting assembly (12) which is connected with a lever assembly (15) through a vertical force sensor (13). The lever assembly (15) is connected with the base (14) through a loading assembly (16). A horizontal force sensor (9) is connected with the friction sheet supporting assembly (12) and a tooth disc (7) is arranged at the other end of the shaft (5). A magnetoelectricity sensor (6) is matched with the tooth disc (7). The quantitative analysis experiment device of the influence rule on the tooth surface friction force by torsional vibration of the shaft system is applied to study on the influence rule of torsional vibration of the shaft system on the tooth surface friction force.

Description

technical field [0001] The invention relates to an experimental device for quantitatively analyzing the law of the influence of shafting torsional vibration on tooth surface friction. Background technique [0002] Due to the inhomogeneity of the output torque of the diesel engine, the uneven excitation of the shafting caused by the rotation of the propeller in the uneven flow field at the stern, the misalignment of the installation of the shafting components, the unevenness of the material and the imbalance of its own quality, etc., Ship propulsion shafting will generate torsional vibrations. And the torsional vibration of the shafting will definitely affect the marine gearbox. When the gears mesh, the friction force of the tooth surface will cause bending stress at the tooth root, which seriously affects the normal operation of the gearbox. Therefore, it is necessary to quantitatively analyze the influence of shafting torsional vibration on tooth surface friction. But at...
