Problems solved by technology

Judging from the current application situation of production enterprises, the damping pulley is still in the exploratory stage due to the limitations of technology and process conditions. The main reason is that the damping mechanism of rubber is similar to the damping spring. To ensure the best effect, it is necessary to select a suitable damping coefficient C. P , while the current design and production units lack the damping coefficient C P The test method cannot detect the performance of the designed vibration-absorbing pulley

Embodiment Construction

[0035] As shown in Figures 1 and 2, the test bench of the embodiment of the present invention includes a bench 1, a motor 2 and a tested vibration-damping pulley 9 on its shaft, a load 3 and a pulley 303 on its shaft, and a tension pulley 4. The motor 2 is a variable frequency speed regulating motor, which is controlled by a computer. The tested vibration-damping pulley 9, the pulley 303, and the tension pulley 4 form a wheel train through the belt 10. As shown in Figure 5, the wheel surface of the outer ring 902 of the tested vibration-damping pulley 9 and the wheel surface of the inner ring 901 draw a white line second mark 904 and first mark 903 through the center of the tested vibration-damping pulley; There is a first mark sensor 601 for sensing the first mark 903 on the inner ring 901, a second mark sensor 602 for sensing the second mark 904 on the outer ring 902, and a radial direction for measuring the vibration-damping pulley 9 under test. The first laser displacemen...

Abstract

The invention relates to a vibration-damping belt pulley performance test table. It includes table frame, motor and vibration-damping belt pulley to be tested on its motor shaft, load and its belt pulley on its shaft and tension pulley; on the side walls of external ring and internal ring of the vibration-damping belt pulley to be tested the marks are respectively set; and on the table frame the mark sensors for sensing marks, laser displacement sensor for measuring radial displacement of the vibration-damping belt pully and laser displacement sensor for measuring axial displacement of the vibration-damping belt pulley; the output end of every sensor is connected with computer system. Besides, said invention also provides the application and action of said test table.

Description

technical field [0001] The invention relates to automobiles, in particular to test equipment used for testing the performance of vibration-absorbing pulleys on automobiles during the design process of automobiles. Background technique [0002] During the driving process of the car, due to the different natural frequencies of the internal parts, the imbalance of the wheels, the engine and the running system, and other factors can easily cause strong vibrations of the whole vehicle and parts. This vibration affects the power, economy, comfort and safety of the car. [0003] Automotive engine accessory gear train refers to a system that drives accessories such as water pumps, fans, generators, and air-conditioning compressors through the main shaft wheel. The main shaft wheel as a driving component is directly connected to the crankshaft, and its running stability directly affects the working state of the accessories and the working quality of the engine. However, when the ca...
