Abstract

A multifunction test bed for testing dynamic balance of gyro-rotor is prepared by setting small pulley on motor output shaft for driving main shaft on body frame through big pulley; fix - connecting body frame and speed regulating device on test bed ; using coupler to combine two parts of main shaft together, setting cam to be tested at middle of main shaft; setting displacement transducer of body frame; connecting main shaft with coder through coupler and forming test system by secondary instrument, computer and display .

Description

technical field [0001] The invention relates to a test device, in particular to a multipurpose test bench for dynamic balance of a rotary body, which is used in the technical field of mechanical engineering. Background technique [0002] The cam mechanism is widely used in various automatic machines, and the quality of the cam parts often determines the working accuracy of the whole machine. Regardless of the design, processing or detection of the cam, the real-time detection of the cam profile curve, the motion analysis and dynamic analysis of the follower are very necessary. The dynamic balance of a rotating body is an important branch of the dynamics content of the mechanical discipline, and it is also one of the important test contents in the field of engineering technology. [0003] After checking the existing technology, it is found that the ZNH-A / 3 cam mechanism test bench of Xinjiang Aoshen Industry and Trade Co., Ltd. has the structure as mentioned above: the whole...
