Close noise detection device of face gear reducer for naval vessel

Abstract

The invention relates to a close noise detection device of a face gear reducer for a naval vessel. The objective of the invention is to solve problems of loading and noise monitoring of the gear reducer in the prior art. The detection device comprises a permanent magnet direct current motor which is connected with a face gear two-path flow-dividing active test box through a coupler. An acceleratedspeed sensor is arranged on the coupler. The face gear two-path flow-dividing active test is connected with a cylinder gear four-path power flow-dividing passive test box through two torsion shafts.A rotation speed torque measurement device is arranged on each torsion shaft. The cylinder gear four-path power flow-dividing passive test box is connected with an electric dynamometer. Anti-vibrationisolation layers are arranged at bottoms of the face gear two-path flow-dividing active test box and the cylinder gear four-path power flow-dividing passive test box. Sound isolation covers are arranged on the exteriors. The accelerated speed sensor, the face gear two-path flow-dividing active test box, a high-precision rotation speed torque measurement device, and the cylinder gear four-path power flow-dividing passive test box are connected with a noise monitoring device.

Description

technical field [0001] The invention belongs to the technical field of ship speed reducer detection, and in particular relates to a closed noise detection device of a ship surface gear speed reducer. Background technique [0002] The high-power face gear power split reducer mentioned in the present invention is a face gear and cylindrical gear two-time split structure, and realizes four-way power split and confluence at the output end, which can meet the needs of ships with high power, high torque, and high speed. Ratio and high power density ratio requirements, large carrying capacity, stable operation, high transmission efficiency, but due to the complexity of this structure, the machining accuracy requirements are very high, therefore, the transmission efficiency, The detection of noise and vibration, oil temperature rise, contact characteristics of gear pairs, load capacity, bearing fatigue life, etc. is essential, but the existing test equipment cannot fully meet the lo...
