Description

Technical Field

[0001] This utility model belongs to the field of gear manufacturing technology, and in particular relates to a noise reduction device for gear manufacturing. Background Technology

[0002] Gears are mechanical components that transmit motion and power through continuous meshing of gears on their rims. During the production process, the operation of the machinery and the characteristics of the gear shape generate a significant amount of noise, causing the noise level of the entire production line to seriously exceed standards and negatively impacting the physical and mental health of workers in the long term. Therefore, noise reduction devices are installed inside and outside the equipment to form soundproof walls to protect the physical and mental health of workers.

[0003] Patent application CN202022235511.5 discloses a noise reduction device for gear production, comprising a rectangular frame; plug-in plates are provided on two adjacent side walls of the rectangular frame; rectangular insertion holes adapted to the plug-in plates are provided on the other two adjacent side walls of the rectangular frame; a noise reduction device is wrapped inside the rectangular frame, comprising two first sound insulation plates and two second sound insulation plates; the two first sound insulation plates are respectively disposed on both sides of the noise reduction device, and the outer surface of the first sound insulation plates is uniformly provided with a plurality of reflective grooves, which are arc-shaped; the second sound insulation plates are disposed inside the first sound insulation plates, and a sealed vacuum layer is formed between the two second sound insulation plates. This utility model forms double noise reduction inside and outside through the first and second sound insulation plates, which can effectively isolate the noise generated during mechanical operation and gear production; the plug-in plates and rectangular slots can realize the splicing and fixing of multiple noise reduction devices, improving the applicability of the noise reduction device.

[0004] The existing technology improves the adaptability and sound insulation effect of noise reduction devices by using multiple sound insulation panels and interlocking plates. However, there are still some shortcomings in the overall use: Although the existing technology achieves splicing and fixing through the interlocking plates, the tightness between the panels is not sufficient. This can cause noise to easily pass through the gap between the two panels to one side, resulting in the noise reduction device not being able to absorb it fully and affecting the sound insulation effect. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this invention provides a noise reduction device for gear production. Through the use of rectangular connecting blocks, connecting bolts, U-shaped pads, and limiting protrusions, this invention ensures a good sealing and fastening effect between the two open frames after splicing. Furthermore, the sealing effect between the two open frames can be adjusted, effectively improving the practicality of the noise reduction device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a noise reduction device for gear production, comprising an open frame and a sound insulation body. The sound insulation body is disposed in the middle of the open frame, and sound-absorbing meshes are disposed on both sides of the sound insulation body. Rectangular connecting blocks are rotatably disposed at each of the four corners of the open frame. Multiple first connecting holes are provided on the four end faces of the rectangular connecting blocks. Fixing plates are provided on two sides of the open frame, and fixing grooves are provided on the other two end faces of the open frame. U-shaped pads are disposed within the fixing grooves. The arrangement of the U-shaped pads and rectangular connecting blocks allows for mutual adjustment and tightening between the two open frames, improving the practicality of the device.

[0007] Preferably, the outer end face of the fixing plate is provided with a plurality of roughened protrusions. The roughened protrusions reduce shaking during insertion and fixing.

[0008] Preferably, the U-shaped pad has multiple limiting protrusions on both side walls, and multiple anti-slip rough surfaces are provided between the multiple limiting protrusions on the top end face of the U-shaped pad. The anti-slip rough surfaces and limiting protrusions ensure the sealing effect of the U-shaped pad on the fixing plate.

[0009] Preferably, sealing gaskets are provided on all four sidewall end faces of the opening frame. The sealing gaskets ensure that the entire mating surface between the two opening frames is sealed.

[0010] Preferably, a connecting bolt is slidably fitted inside the first connecting hole, and a connecting nut is threaded onto the outside of the connecting bolt. The connection bolt and nut allow for adjustment of the gap between the two open frames, thus enabling tightening.

[0011] Preferably, the connecting nut has an internal hexagonal hole on its side wall. The internal hexagonal hole facilitates quick assembly and disassembly of the connecting nut.

[0012] Preferably, all four sidewalls of the rectangular connecting block are roughened. The rectangular connecting block design prevents slippage between the connecting bolts and nuts.

[0013] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0014] This utility model, through the use of sealing gaskets, U-shaped gaskets, limiting protrusions, and rectangular connecting blocks, effectively improves the sealing, fastening, and shock resistance between the two open frames. Furthermore, operators can adjust the sealing tightness between the two open frames to ensure noise reduction, making the device more suitable for various production environments and improving its applicability.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example 1:

[0025] refer to Figure 1-8 A noise reduction device for gear production includes an open frame 30 and a sound insulation body 41. The sound insulation body 41 is provided in the middle of the open frame 30, and sound-absorbing mesh 31 is provided on both sides of the sound insulation body 41. Rectangular connecting blocks 35 are rotatably provided at the four corners of the open frame 30. Multiple first connecting holes 36 are provided on the four end faces of the rectangular connecting blocks 35. Fixing plates 32 are provided on two side faces of the open frame 30, and fixing grooves 33 are provided on the other two end faces of the open frame 30. U-shaped pads 43 are provided in the fixing grooves 33.

[0026] Specifically, the opening frame 30 is frame-shaped with a hollow center. Workers can place the opening frame 30 outside the gear production equipment. By stacking multiple opening frames 30 together, a sound insulation wall is formed, thereby achieving noise reduction. In this context, the sound insulation body 41 and the sound-absorbing mesh 31 set in the middle of the opening frame 30 are existing technologies. The sound-absorbing mesh 31 is arranged in a mesh pattern on both sides of the sound insulation body 41. This solution will not be elaborated on further, but it can effectively block and eliminate noise, thereby ensuring a good production environment.

[0027] When it is necessary to splice and install the opening frame 30, the staff can insert the fixing plate 32 on one side end face of one of the opening frame 30 into the fixing groove 33. The fixing groove 33 is equipped with a U-shaped pad 43. The U-shaped pad 43 is U-shaped and made of elastic sealing material. It can wrap and fix the outer end face of the fixing plate 32, which can improve the fixing effect and ensure the sound insulation effect and quality after splicing the two opening frames 30.

[0028] After multiple open frames 30 are assembled, the workers can rotate multiple rectangular connecting blocks 35 so that the first connecting holes 36 on the rectangular connecting blocks 35 between two adjacent open frames 30 are aligned with each other. They can then be connected by connectors, thereby improving the fixing and seismic resistance effect. In this relationship, the rectangular connecting blocks 35 are rotatably set on the end face of the open frame 30, so that the multiple first connecting holes 36 can be quickly adjusted in position, which is convenient for installation and fixing.

[0029] refer to Figure 5 A connecting bolt 37 is provided in the first connecting hole 36 for sliding fit, and a connecting nut 39 is provided on the outside of the connecting bolt 37 for thread fit.

[0030] Specifically, after the multiple open frames 30 are assembled, the workers can insert one end of the connecting bolt 37 into the first connecting hole 36 in the two rectangular connecting blocks 35, and then rotate the connecting nut 39 on the outside of the connecting bolt 37. During this process, the two open frames 30 will be pulled together, so that the fixing plate 32 can be better pressed into the U-shaped pad 43, thereby improving the sound insulation and shock resistance.

[0031] refer to Figure 7 Multiple rough-surfaced protrusions 42 are provided on the outer end face of the fixing plate 32.

[0032] Specifically, the U-shaped pad 43 creates multiple raised surfaces on the outside of the fixing plate 32, which increases the contact friction between the plate and the U-shaped pad 43, thereby improving the pressing stability.

[0033] refer to Figure 8 Multiple limiting protrusions 45 are provided on both sides of the U-shaped pad 43, and multiple anti-slip rough surfaces 44 are provided between the multiple limiting protrusions 45 on the top end face of the U-shaped pad 43.

[0034] Specifically, the limiting protrusion 45 protrudes outward from the side wall end face of the U-shaped pad 43. When the fixing plate 32 is pressed into the U-shaped pad 43, it can produce a certain elastic deformation, which can effectively improve the sealing tightness. The anti-slip rough surface 44, together with the rough surface protrusion 42 on the end face of the fixing plate 32, can improve the fastening effect and ensure shock resistance.

[0035] refer to Figure 5 The connecting nut 39 has an internal hexagonal hole 40 on its side wall.

[0036] Specifically, both the connecting nut 39 and the connecting bolt 37 have internal hexagonal holes 40 on their nut end sidewalls. When the space is small during installation and the caliper wrench cannot be inserted, the internal hexagonal wrench can be inserted into the internal hexagonal hole 40 to complete the locking of the connecting nut 39.

[0037] refer to Figure 5 The four side walls of the rectangular block 35 are all roughened.

[0038] Specifically, the roughening treatment of the sidewall of the rectangular connecting block 35 can prevent slippage when the connecting nut 39 and the connecting bolt 37 are fixed, thus improving the fixing effect.

[0039] Example 2:

[0040] Based on or differing from Embodiment 1, refer to Figure 8 Sealing gaskets 34 are provided on all four side wall ends of the opening frame 30.

[0041] Specifically, the sealing gaskets 34 are set on the four end faces of the opening frame 30. When the fixing plate 32 is inserted into the fixing groove 33, the sealing gaskets 34 on the side walls of the two opening frames 30 will also fit together, thereby improving the sealing effect. When the two rectangular connecting blocks 35 are locked by the connecting bolts 37, the sealing gaskets 34 on the side walls of the two opening frames 30 can be pressed, thereby improving the fastening effect.
