Abstract

The invention discloses a vibration test device for a two-stage fixed axis gear drive mechanism. The vibration test device comprises a first pump motor, a speed-up box, a first torque sensor, a gearbox, a second torque sensor, a reduction box and a second pump motor which are connected in sequence. The speed-up box, the gear box and the reduction box are connected with a lubricating pump station system. According to the invention, requirements for the vibration test under low-speed, high-speed, light-load and heavy load conditions are met, and unification of the torsional oscillation test of the two-stage fixed axis gear drive mechanism and the coupled vibration test transposition is achieved. With the adoption of the vibration test device provided by the invention, torque of input and output ends of a speed change mechanism and various vibration parameters such as acceleration, displacement, rotating speed and stress of key parts in the fixed axis gear train can be obtained accurately and conveniently, analysis of dynamics and fatigue strength can be carried out further according to the parameters, and the system design is optimized.

Description

technical field [0001] The invention belongs to the technical field of gear transmission mechanisms, and relates to a vibration test device for a two-stage fixed-axis gear transmission mechanism, and is especially suitable for a vibration test device for a two-stage fixed-axis gear transmission mechanism working at a high rotational speed. Background technique [0002] Gear transmission is one of the most widely used forms of mechanical transmission, and it plays a key role in equipment in machinery, aerospace, shipbuilding and other industries. [0003] As the gear transmission system develops towards high speed, the vibration of the gear transmission system will intensify under the joint action of internal and external excitations, and a large part of the vibration of mechanical equipment comes from this. Vibration causes wear, fatigue damage, noise, and the actual law of motion deviates from the theoretical law of motion, resulting in errors, reducing the safety, reli...
