Vibration and noise integrated testing machine for experimental research of gear characteristics of speed reducer

Abstract

The invention discloses a vibration and noise integrated test machine for speed reducer gear characteristic experiment research, which comprises a test board and an outer frame supporting structure which is the main equipment, a hydraulic cylinder is arranged on the outer surface of the test board, the other end of the hydraulic cylinder is connected with a supporting frame, and the supporting frame is located on the opposite surface of the test board; the reduction gearbox is located on the outer surface of one end of the test board, a first rotating shaft and a second rotating shaft are arranged in the reduction gearbox, and the output end of the second rotating shaft is connected with a gear motor. According to the vibration and noise integrated testing machine for the speed reducer gear characteristic experiment research, the hydraulic cylinder stretches and retracts between the testing table and the supporting frame, the distance between the testing table and the supporting frame can be adjusted, and when a to-be-tested gear is replaced, one end of the connecting shaft can be separated from the interior of the connecting cylinder in a transverse adjustment mode; the to-be-tested gear is convenient to replace, and the steps required by replacement are reduced, so that the testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gear characteristic testing, in particular to a vibration and noise integrated testing machine for experimental research on gear characteristic of a reducer. Background technique [0002] Gear transmission is an important transmission form of power transmission, which plays an important role in the fields of automobiles, ships, aerospace and aviation. With the development of science and technology and the improvement of use requirements, the transmission power of gears is gradually increasing, and the operating speed is gradually increasing. Gear vibration and noise requirements are getting higher and higher. Gear vibration and noise are important indicators for evaluating gear transmission performance. Research on gear vibration and noise can provide technical support for high-performance gear design and manufacturing. Due to the characteristics of the heavy-duty operating environment, the existing gear ...
