To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description is given to the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments as follows:
a noise tester of an engine belt tensioner is shown in figures 1 and 2 and comprises a base 1, a motor 2, a sound insulation box 3, a connecting plate 4, a first rotating wheel 5, a second rotating wheel 6, a first transmission belt 7, a second transmission belt 8, a tensioner 9, a pressure gauge 10, a support column 11 and a push rod 12.
The motor 2 is fixedly arranged on the base 1 and used for providing power.
The soundproof case 3 is provided above the base 1 via a movable bracket 23, and the positional relationship between the base 1 and the soundproof case 3 can be adjusted by the movable bracket 23. The sound insulation box 3 is a square housing, the housing is composed of an inner wall, an outer wall and sound insulation cotton filled between the inner wall and the outer wall, and the sound insulation box 3 is used for reducing interference of external sound during testing.
The application provides a movable support 23, the bottom and the base 1 spiral setting of movable support 23, the top and the 3 normal running fit of sound-proof box of movable support 23. When the movable support 23 is rotated, the distance between the base 1 and the movable support 23 is changed, and the distance between the base 1 and the soundproof box 3 is not changed, so that the distance between the base 1 and the soundproof box 3 is adjusted by the movable support 23. In order to adjust the movable support 23 conveniently, the middle part of the movable support 23 is provided with an auxiliary rod, and the movable support 23 is adjusted by rotating the auxiliary rod, so that the adjustment is convenient and efficient.
The connecting plate 4 is provided in the soundproof case 3 for fixing other components. First runner 5 is fixed to be set up on connecting plate 4 and is located sound-proof box 3, and second runner 6 is fixed to be set up on connecting plate 4 and is located sound-proof box 3, and connecting plate 4 has played the effect of fixed first runner 5 and second runner 6. Preferably, the connecting plate 4 is a sliding plate, the connecting plate 4 and the lead screw 13 are rotatably arranged, and the lead screw 13 is rotatably arranged on the soundproof box 3. By means of the roller screw principle, the movement of the connecting plate 4, i.e. the first 5 and second 6 turning wheels, is achieved by rotating the screw 13, thereby adjusting the contact position of the tensioner 9 with the second belt 8 between the first 5 and second 6 turning wheels.
A first drive belt 7 connects the first turning wheel 5 with the motor 2 and a second drive belt 8 connects the first turning wheel 5 with the second turning wheel 6. The motor 2 drives the first rotating wheel 5 to rotate through the first transmission belt 7, and when the first rotating wheel 5 rotates, the second transmission belt 8 moves along with the first rotating wheel, so that the second rotating wheel 6 is driven to rotate.
The detected tensioner 9 is installed in the wheel train consisting of the first rotating wheel 5, the second rotating wheel 6 and the second transmission belt 8. A tensioner 9 is arranged in contact with the second belt 8, by means of which tensioner 9 the tightness of the second belt 8 can be adjusted. The pressure gauge 10 is arranged at the bottom end of the tensioner 9, and the top end of the support post 11 is arranged in contact with the pressure gauge 10. The noise measurement of the tensioner 9 is measured when it is tensioning the belt and running, and different tensioners 9 tension the second drive belt 8 by adjusting the mounting position differently.
When the post 11 is fixed, the second belt 8 gives the tensioner 9 a reaction force according to the relation between the force and the reaction force, which is then reflected on the pressure gauge 10. At this time, it is preferable that the display screen of the pressure gauge 10 is provided outside the tensioner 9, and the side of the soundproof case 3 opposite to the display screen of the pressure gauge 10 is transparent. The technician may record the value displayed by the gauge 10 at an outside time.

Because the motor 2 is arranged at the bottom end of the soundproof box 3, the first transmission belt 7 can pass through the soundproof box 3 without fail, and the movement condition of the connecting plate 4 is considered, two pairs of rollers 16 are designed, the first transmission belt 7 is arranged between the rollers 16, the movement of the first transmission belt 7 is limited by the rollers 16, and the soundproof measures can be conveniently carried out at the bottom end of the soundproof box 3.
During testing, the measurement is carried out in a relatively quiet environment, external noise interference is reduced as much as possible, and each measurement is carried out in the same environment as much as possible so as to facilitate transverse comparison. Under the action of motor 2, first drive belt 7 and second drive belt 8 rotate, second drive belt 8 generates different rotating speeds, tensioner 9 also makes second drive belt 8 have different tightness, the noise generated by tensioner 9 and second drive belt 8 in motion is collected by microphone 14 of sound meter 15, and the noise generated by tensioner 9 in motion can be displayed by sound meter 15. In addition, by adjusting the rotary screw 13 and the movable bracket 23 cooperatively, the contact position of the tensioner 9 and the second transmission belt 8 can be realized, so that the measurement of the noise at different positions of the tensioner 9 and the second transmission belt 8 can be realized.
