Description
Technical Field
[0001] The utility model relates to the field of belt production inspection, in particular to belt noise detection equipment. Background Art
[0002] Belt drive uses a tensioned (annular) belt that is put on the pulleys of two drive shafts. It relies on the friction generated when the belt and pulley are tensioned to transmit the power of one shaft to the other shaft. Belt rotation can be used for large-distance transmission between two shafts (working machine and power machine). Because the belt is elastic, it can mitigate impact, reduce vibration, and ensure smooth transmission.
[0003] Belt transmission generates noise when working. The noise mainly comes from the friction between the belt and the pulley, and the friction between the belt and the pulley and the air. The causes of these noises are mainly related to the tightness of the belt and the material of the belt. Therefore, a belt needs to be tested with corresponding equipment during production to evaluate the noise level of the belt at different speeds during operation, so as to improve the belt based on this data.
[0004] Belt noise detection equipment usually sets the belt on the corresponding pulley, and then uses a driving component to drive the pulley to rotate at different speeds to drive the belt to work, and then uses a decibel tester to measure the noise generated by the belt when it is working. However, in actual applications, the detection of belt noise is easily interfered by external noise, making the belt noise detection difficult. The decibel meter is mainly used to measure the intensity of noise, resulting in insufficient data for analyzing and improving the belt. Utility Model Content

[0033] See also Figure 4 Two groups of fixed rods 6 are provided, and movable seats 7 are movably installed outside the two groups of fixed rods 6. The movable seats 7 can slide outside the fixed rods 6. By providing two groups of fixed rods 6, the movable seats 7 are more stable when sliding outside the fixed rods 6.
[0034] See also Figure 4 The turntable 9 and the rotating shaft 10 are connected by a gear set. By setting the gear set, the rotation of the rotating shaft 10 can drive the turntable 9 to rotate, and the stop clamp 11 can limit the rotation of the turntable 10, thereby limiting the rotation of the rotating shaft 9, so that the stop clamp 11 can reduce the belt speed.
[0035] See also Figure 4 A stop clamp 11 is installed on one side of the mounting frame 8. The stop clamp 11 can reduce the rotation of the turntable 9. By setting the stop clamp 11, the rotation speed of the belt can be reduced.
[0036] See also Figure 3A universal bracket 14 is installed on the top of the fixed plate 2, and a sound sensor 15 is installed at the end of the universal bracket 14. The universal bracket 14 can freely adjust the position of the sound sensor 15.

[0040] The working principle of the utility model is as follows: when it is necessary to inspect the belt, firstly, one end of the belt is sleeved on the first pulley 5, and then the start cylinder 12 is adjusted to adjust the second pulley 13 to a height suitable for belt installation, the cylinder 12 drives the movable seat 7 to slide on the fixed rod 6, and the height of the movable seat 7 is adjusted, thereby adjusting the height of the mounting frame 8, and then adjusting the height of the second pulley 13, and then the other end of the belt is sleeved on the second pulley 13, and then the cylinder 12 is continued to be started to adjust the height of the second pulley 13, so that the first pulley 5 and the second pulley 13 tighten the belt.
[0041] Next, start the motor 4 through the controller outside the equipment cover 1, select the appropriate speed, the motor 4 will drive the first pulley 5 to rotate, and then drive the second pulley 13 to rotate through the belt.
