Description

Technical Field

[0001] This utility model relates to the field of shock absorbers, and more particularly to an adjustable silicone oil shock absorber. Background Technology

[0002] Silicone oil dampers are industrial devices that utilize the damping effect of silicone oil to reduce torsional vibration of engine crankshafts. Through the high viscosity and excellent vibration absorption properties of silicone oil, these dampers can absorb and buffer the vibration energy transmitted by the crankshaft when the engine is running at high speeds, thereby significantly reducing the vibration amplitude and improving the engine's smooth operation and service life. Silicone oil dampers are widely used in engine systems of automobiles, ships, and various mechanical equipment, becoming an important component for ensuring stable engine operation.

[0003] In daily work, it has been found that the damping effect of silicone oil vibration dampers cannot be flexibly adjusted due to their fixed design. This means that they cannot be adjusted to adapt to specific needs when facing various different usage scenarios. Whether it is a heavy-load environment that requires greater damping force or a light-load environment that requires less damping force, silicone oil vibration dampers are difficult to provide the corresponding matching effect, thus limiting their applicability and effectiveness in diverse applications. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing silicone oil vibration dampers cannot be adjusted to meet specific needs. Whether it is a heavy-load environment requiring greater damping force or a light-load environment requiring less damping force, silicone oil vibration dampers cannot provide the corresponding matching effect, thus limiting their applicability and effectiveness in diverse applications. Therefore, an adjustable silicone oil vibration damper is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable silicone oil shock absorber, comprising an oil reservoir and a top cover, wherein the oil reservoir is filled with silicone oil, and the top cover is fixedly installed on the top of the oil reservoir. Four mounting grooves are provided on the surfaces of both the oil reservoir and the top cover. An opening is provided on the top of the top cover. An output shaft is rotatably connected to the opening. An installation port is provided at the top of the output shaft. An opening is provided on the surface of the output shaft. An adjustment component is provided at the top of the opening.

[0006] The adjustment assembly includes a first drive shaft, which is rotatably connected to the second surface of the opening. A knob is fixedly installed on the top of the first drive shaft, and a second drive shaft is fixedly connected to the bottom of the first drive shaft. A fixing block is fixedly connected to the bottom of the second drive shaft.

[0007] Preferably, a damping plate is fixedly installed at the bottom of the output shaft. The damping plate is disposed inside the oil reservoir. A rotating hole is formed on the surface of the damping plate, and the rotating hole is rotatably connected to the second transmission shaft.

[0008] Preferably, the damping plate has three or more damping holes equidistantly spaced on its surface.

[0009] Preferably, three or more slide rails are equidistantly installed at the bottom of the fixed block, and a first slider is slidably connected to the surface of the slide rails, with a rotating shaft fixedly installed on the upper surface of the first slider.

[0010] Preferably, a second slider is rotatably connected to the surface of the rotating shaft, and a stop is fixedly installed on the side of the first slider near the damping hole, the stop completely blocking the damping hole.

[0011] Preferably, an adjustment plate is fixedly installed at the bottom of the fixed block, and the adjustment plate is located at the bottom of the first slider.

[0012] Preferably, the surface of the adjustment plate has three or more adjustment grooves, the adjustment grooves are arc-shaped, and the adjustment grooves are slidably connected to the second slider.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, the damper can be installed in a predetermined position via the mounting slot, and the mounting port at the top of the output shaft can be installed with the object to be damped. When the output shaft rotates, the damping plate will dampen under the damping of the silicone oil because the oil reservoir is filled with silicone oil, thus ensuring the stable operation of the object to be damped. The operator can rotate the knob to drive the first and second drive shafts, which will cause the fixed block to rotate, thereby rotating the adjustment plate. Because the adjustment groove on the surface of the adjustment plate is arc-shaped, it drives the second slider and the rotating shaft to push the first slider. The first slider slides along the slide rail, thereby blocking the damping hole with the stop block, thus changing the contact area between the damping fluid and the damping plate. When the damping hole is completely blocked by the stop block, the contact area is the largest and the damping effect is the strongest; when the damping hole is not blocked by the stop block, the contact area is the smallest and the damping effect is the weakest. Furthermore, the operator can freely adjust the state of the damping hole being blocked by the stop block, thereby achieving adjustment of the damping effect under various conditions.

[0021] Please see Figure 1-5 This utility model provides a technical solution: an adjustable silicone oil shock absorber, including an oil reservoir 1 and a top cover 2. The oil reservoir 1 is filled with silicone oil, and the top cover 2 is fixedly installed on the top of the oil reservoir 1. The surfaces of the oil reservoir 1 and the top cover 2 are provided with four mounting grooves 21. The top of the top cover 2 is provided with an opening 1, and an output shaft 3 is rotatably connected to the opening 1. The top of the output shaft 3 is provided with a mounting port 31, and the surface of the output shaft 3 is provided with an opening 2. An adjustment component 4 is provided on the top of the opening 2.

[0022] In this embodiment: the adjustment component 4 includes a first drive shaft 42, which is rotatably connected to the surface of the second opening. A knob 41 is fixedly installed on the top of the first drive shaft 42, and a second drive shaft 421 is fixedly connected to the bottom of the first drive shaft 42. A fixing block 43 is fixedly connected to the bottom of the second drive shaft 421.

[0023] Specifically, a damping plate 32 is fixedly installed at the bottom of the output shaft 3. The damping plate 32 is located inside the oil reservoir 1. A rotating hole 33 is opened on the surface of the damping plate 32. The rotating hole 33 is rotatably connected to the second transmission shaft 421.

[0024] In this embodiment: when the output shaft 3 rotates, because the oil reservoir 1 is filled with silicone oil, the damping plate 32 will reduce vibration under the damping of the silicone oil, thereby ensuring the stable operation of the object being damped.

[0025] Specifically, the damping plate 32 has three or more damping holes 321 equidistantly spaced on its surface.

[0026] Specifically, three or more slide rails 44 are equidistantly installed on the bottom of the fixed block 43, and a first slider 441 is slidably connected to the surface of the slide rail 44. A rotating shaft 443 is fixedly installed on the upper surface of the first slider 441.

[0027] Specifically, a second slider 4431 is rotatably connected to the surface of the rotating shaft 443, and a stop 442 is fixedly installed on the side of the first slider 441 near the damping hole 321. The stop 442 can completely block the damping hole 321.

[0028] In this embodiment, the stop block 442 can block the damping hole 321, thereby changing the contact area between the damping fluid and the damping plate 32. When the damping hole 321 is completely blocked by the stop block 442, the contact area is the largest and the damping effect is the strongest. When the damping hole 321 is not blocked by the stop block 442, the contact area is the smallest and the damping effect is the weakest. Furthermore, the operator can freely adjust the state in which the damping hole 321 is blocked by the stop block 442, thereby achieving adjustment of the damping effect under various conditions.

[0029] Specifically, an adjustment plate 45 is fixedly installed at the bottom of the fixed block 43, and the adjustment plate 45 is located at the bottom of the first slider 441.

[0030] Specifically, the surface of the adjustment plate 45 has three or more adjustment grooves 451, the adjustment grooves 451 are arc-shaped, and the adjustment grooves 451 are slidably connected to the second slider 4431.

[0031] In this embodiment: rotating the knob 41 drives the first drive shaft 42 and the second drive shaft 421. The second drive shaft 421 causes the fixed block 43 to rotate, thereby causing the adjusting plate 45 to rotate. Since the adjusting groove 451 on the surface of the adjusting plate 45 is arc-shaped, it drives the second slider 4431 and the rotating shaft 443 to push the first slider 441. The first slider 441 slides along the slide rail 44, thereby causing the stop block 442 to block the damping hole 321.

[0032] Working principle: The vibration damper can be installed in a predetermined position through the mounting slot 21. The mounting port 31 at the top of the output shaft 3 can be installed with the object to be damped. When the output shaft 3 rotates, because the oil reservoir 1 is filled with silicone oil, the damping plate 32 will dampen the vibration under the damping of the silicone oil, thereby ensuring the stable operation of the object to be damped. The operator can rotate the knob 41 to drive the first drive shaft 42 and the second drive shaft 421. The second drive shaft 421 will cause the fixed block 43 to rotate, thereby causing the adjusting plate 45 to rotate. Because the adjusting groove 451 on the surface of the adjusting plate 45 is arc-shaped, The second slider 4431 and the rotating shaft 443 drive the first slider 441, which slides along the slide rail 44, thereby blocking the damping hole 321 with the stop block 442. This changes the contact area between the damping fluid and the damping plate 32. When the damping hole 321 is completely blocked by the stop block 442, the contact area is the largest and the damping effect is the strongest. When the damping hole 321 is not blocked by the stop block 442, the contact area is the smallest and the damping effect is the weakest. Furthermore, the operator can freely adjust the state in which the damping hole 321 is blocked by the stop block 442, thereby achieving adjustment of the damping effect under various conditions.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
