Description

Technical Field

[0001] The utility model relates to the technical field of vibration reduction and noise reduction of air compressors, in particular to a low-noise integrated twin-screw air compressor. Background Art

[0002] An air compressor, also known as an air compressor, includes motors, oil and gas barrels, coolers, filters and other accessories. It is the main body of the air source device. It is a device that converts the mechanical energy of the motor into gas pressure energy. It is a compressed air pressure generating device. It is mainly driven directly by an electric motor to drive the yin and yang rotors to rotate, and the required pressure gas is generated through changes in the rotor volume.

[0003] During the operation of the twin-screw air compressors on the market, since they need to complete the repetitive work of suction, compression and exhaust, rubber columns are usually added at the bottom of the motor to alleviate the noise caused by vibration. However, the motor has low stability and strong vibration. The noise reduction and vibration reduction effect of the simple rubber column is poor. In addition, the rubber column is solid to support the motor. Solid rubber itself is harder and still has large noise and vibration problems. Therefore, stronger vibration and noise reduction measures are needed in actual use. Utility Model Content

[0030] See also Figure 1-4 The utility model provides a low-noise integrated twin-screw air compressor, comprising: a chassis 1, a noise reduction and vibration reduction component 2, a support plate 3, and a twin-screw air compressor component 4.

[0031] When in use, the noise reduction and vibration reduction component 2 is installed at the bottom of the support plate 3. During the operation of the motor in the twin-screw air compressor assembly 4, the vibration force generated presses down the inner rod 22, and the connecting plate 23 moves down, so that the top rod 29 brings the cross plate 210 to pressurize the hydraulic chamber 211. The hydraulic pressure in the hydraulic chamber 211 buffers the vibration force, which has the effect of effectively reducing the vibration of the screw air compressor assembly 4, and when the connecting plate 23 moves down, it moves with the connecting frame 24, and the rotating rod 25 brings the gear 26 to move down. The gear 26 meshes with the tooth plate 27 and rotates when it moves down, causing the helical gear set 28 to rotate, thereby converting the downward exciting force into the rotational motion of the helical gear set 28, thereby enhancing the buffering and vibration reduction of the motor, and then realizing the low-noise operation of the air compressor.

[0032] According to some embodiments of the present application, optionally, the outer wall of the inner rod 22 is in contact with the inner wall of the outer rod 21 , which has the effect of increasing the sealing performance between the inner rod 22 and the outer rod 21 .

[0033] According to some embodiments of the present application, the helical gear set 28 is optionally provided with two meshing helical gears, one of which is mounted on the rotating rod 25 and the other is rotatably mounted on the lower side of the connecting plate 23. The downward excitation force drives the helical gear set 28 to perform circular motion.

[0034] According to some embodiments of the present application, optionally, the helical gear on the lower side of the connecting plate 23 can rotate through a bearing, and the rotating rod 25 can rotate through a bearing on the connecting frame 24. This has the effect of achieving more flexible rotation of the helical gear set 28.
