The adaptive tunable inertial vibration device can obtain a certain amount and magnitude of vibration of the excited object, thereby vibrating and testing the object, or calibrating the vibration testing instrument and the sensor. The vibration exciter can also be used as an excitation component to form a vibration machine for material, object transportation, screening, compaction, molding and soil sand and gravel tamping.
振動機械一般由激振器、工作機體、阻尼器和彈性元件所組成，激振器是振動機械成敗的關鍵所在，激振器可產生單向的或多向的，簡諧的或非簡諧的激勵力。若就單軸慣性振動機械只在x-y平面上簡單運動之系統而言，作用于振動質體上的力包括機體慣性力、阻尼力、彈性力和激振力，再振動的每一個瞬間，總合力為零(力平衡原則)，因此x-y平面上質心點在x、y軸方向運動平衡方程式，可寫成Vibrating machinery is generally composed of a vibration exciter, a working body, a damper and an elastic element. The exciter is the key to the success of the vibrating machine. The exciter can produce one-way or multi-directional, simple or non-harmonic Motivation. In the case of a system in which the uniaxial inertial vibration machine moves only in the xy plane, the forces acting on the vibrating mass include the inertial force, the damping force, the elastic force, and the exciting force of the body, and each moment of the vibration, the total The resultant force is zero (force balance principle), so the centroid point on the xy plane is in the x and y-axis motion balance equation, which can be written as
式中m機體質量體、m 0不平衡塊質量、F Y (t)=m 0 rω2為通過機台的質量中心Y軸方向的激振力、F X (t)=m 0 rω2為通過機台的質量中心X軸方向的激振力、C Y 為通過機台的質量中心Y軸方向的阻尼力、C X 為通過機台的質量中心X軸方向的阻尼力、K Y 為通過機台的質量中心Y軸方向的彈性力、K X 為通過機台的質量中心X軸方向的彈性力，若阻尼力、彈性力忽略不計，則機體慣性力mω 2 A和不平衡塊慣性力m 0 rω 2互相平衡，則機體的振幅。Where m body mass, m 0 unbalance mass, F Y ( t )= m 0 r ω 2 is the exciting force in the Y- axis direction of the mass center of the machine, F X ( t )= m 0 r ω 2 is the exciting force in the X- axis direction of the mass center passing through the machine, C Y is the damping force in the Y- axis direction passing through the center of the machine center, C X is the damping force in the X- axis direction passing through the mass center of the machine, K Y In order to pass the elastic force in the Y- axis direction of the mass center of the machine, K X is the elastic force in the X- axis direction passing through the center of the mass center of the machine. If the damping force and the elastic force are neglected, the inertia force mω 2 A and the unbalanced block of the body The inertial force m 0 rω 2 is balanced with each other, then the amplitude of the body .

The vibration machine 90 can have a plurality of elastic brackets 96. The elastic brackets are provided with a frame. The frame is provided with a plurality of sieve trays 95 and a plurality of phase-connected and synchronously rotating transmission shafts 10, wherein one of the transmission shafts 10 is fixed at one end. There is a pulley 92, and a drive belt 93 is wound around the pulley 10. The drive belt 93 is coupled to a motor 94 for driving the drive shaft 10 for rotation. Additionally, the drive shaft 10 can be non-circular in cross section, such as a square.
可將複數自適應可調幅慣性激振裝置設置在兩傳動軸10上，各自適應可調幅慣性激振裝置包含一振幅調整機構30以及一自適應調整機構20。此外，前述傳動軸10可視為自適應可調幅慣性激振裝置的元件之一。A plurality of adaptive adjustable amplitude inertial excitation devices can be disposed on the two transmission shafts 10. Each of the adaptive adjustable amplitude inertial excitation devices includes an amplitude adjustment mechanism 30 and an adaptive adjustment mechanism 20. Furthermore, the aforementioned drive shaft 10 can be considered as one of the components of an adaptive adjustable amplitude inertial vibration device.
該振幅調整機構30固定在其中一傳動軸10上，且具有一調整機構框架31、一定位螺桿32、一定位螺帽33以及一定位彈性元件36。The amplitude adjustment mechanism 30 is fixed to one of the transmission shafts 10 and has an adjustment mechanism frame 31, a positioning screw 32, a positioning nut 33 and a positioning elastic member 36.
該調整機構框架31大致呈一U形，在調整機構框架31上形成一定位槽310，該定位槽310可為非圓形，例如方形，以匹配具有非圓形截面的傳動桿10，且可穿套在傳動軸31上。在調整機構框架31上貫穿形成有一與定位槽310連通的螺孔315。在調整機構框架31兩側上分別向外突伸出一固定板311，各固定板311貫穿形成有一通孔312。The adjusting mechanism frame 31 is substantially U-shaped, and a positioning slot 310 is formed on the adjusting mechanism frame 31. The positioning slot 310 can be non-circular, for example, square, to match the transmission rod 10 having a non-circular cross section, and It is put on the drive shaft 31. A screw hole 315 communicating with the positioning groove 310 is formed through the adjustment mechanism frame 31. A fixing plate 311 is protruded outwardly on both sides of the adjusting mechanism frame 31, and each of the fixing plates 311 is formed with a through hole 312.
該定位螺桿32貫穿設置於調整機構框架31的螺孔315內並且可伸入定位槽310而緊迫抵靠該傳動軸10。The positioning screw 32 is disposed in the screw hole 315 of the adjustment mechanism frame 31 and can protrude into the positioning groove 310 to press against the transmission shaft 10 .
該定位螺帽33螺鎖在定位螺桿32上並且可緊迫抵靠調整機構框架31以使定位螺桿32固定而無法轉動，鬆開定位螺帽33可讓定位螺桿32恢復轉動。The positioning nut 33 is screwed onto the positioning screw 32 and can be pressed against the adjustment mechanism frame 31 to fix the positioning screw 32 and cannot be rotated.

兩導向螺栓22係分別穿過調整機構框架31上的通孔312，並且分別螺鎖在兩調整螺孔210內，使得不平衡塊21固定在調整機構框架31上。轉動定位螺桿32以及導向螺栓22可改變不平衡塊21相對調整機構框架31的距離，因此可改變固定偏心距(傳動軸10軸心與不平衡塊21質心之距離)。(偏心距=固定偏心距+動態偏心距，固定偏心距經設定後不再改變，動態偏心距隨轉數條件增加或減少。)The two guide bolts 22 respectively pass through the through holes 312 in the adjustment mechanism frame 31, and are respectively screwed into the two adjustment screw holes 210, so that the unbalanced block 21 is fixed on the adjustment mechanism frame 31. Rotating the positioning screw 32 and the guide bolt 22 can change the distance of the unbalanced block 21 relative to the adjustment mechanism frame 31, and thus the fixed eccentricity (the distance between the axis of the drive shaft 10 and the center of mass of the unbalanced block 21) can be changed. (Eccentricity = fixed eccentricity + dynamic eccentricity, the fixed eccentricity does not change after setting, and the dynamic eccentricity increases or decreases with the number of revolutions.)

When the adjusting spacers 24 are provided, the elastic members 25 are respectively abutted against the corresponding fixing plates 311 and the adjusting pads 24, respectively.
在本發明的使用上，不平衡塊21透過導向螺栓22、調整螺帽23、調整墊片24、彈性元件25以及調整機構框架31將自適應調整機構20固定於方型傳動軸10上，利用定位彈性元件36、定位螺桿32調整固定偏心距的大小，再用定位螺帽33鎖固確保工作中偏心距的穩定性，調整彈性元件25的鬆緊使其作用力大於不平衡塊21在振動機械90固有頻率時的慣性力，使振動機械90在到達工作頻率前的振幅僅是固定偏心距的作用產生，並不是最大振幅。在振動機械90的操作頻率通過固有頻率後才經由動態偏心距(下列所述的ΔR)的增加逐漸達到設定轉數時的最大值。In the use of the present invention, the unbalanced block 21 fixes the adaptive adjustment mechanism 20 to the square transmission shaft 10 through the guide bolt 22, the adjustment nut 23, the adjustment spacer 24, the elastic member 25, and the adjustment mechanism frame 31, and utilizes The positioning elastic member 36 and the positioning screw 32 adjust the size of the fixed eccentricity, and then the positioning nut 33 is locked to ensure the stability of the eccentricity during the work, and the elasticity of the elastic member 25 is adjusted to make the force larger than the unbalanced block 21 in the vibration machine. The inertial force at 90 natural frequency causes the amplitude of the vibrating mechanism 90 before reaching the operating frequency to be only a fixed eccentricity, not the maximum amplitude. In operation frequency of the vibration from the machine 90 (following the Δ R) is gradually increased when the maximum set number of revolutions after the natural frequency by dynamically via an eccentric.
