Original WEICHAI Silicone shock absorber 13068682

Description

Silicone shock absorber 13068682 Structure composition:

1. Silicone shock absorber 13068682 housing: Usually made of metal materials such as cast iron or aluminum alloy, it has certain strength and stiffness, capable of withstanding the vibration and torque generated by the engine’s operation. There is a through hole in the center of the Silicone shock absorber 13068682 housing, which is used to fit the engine crankshaft, connecting it to the crankshaft and moving together.
2. Inertial block: Generally made of materials with high density such as steel or iron, it has a large mass and rotational inertia. The inertial block is installed in the cavity formed by the housing and the cover plate, separated axially from the housing by bearings, and can freely rotate within the cavity relative to the housing.
3. Cover plate: Used to seal the inertial block, bearing, silicone oil, etc. in the shock absorber housing, preventing the leakage of silicone oil, and also serving to fix and support the inertial block.
4. Bearings: Play the role of axially separating the inertial block from the shock absorber housing, allowing the inertial block to freely rotate within the housing, and reducing the friction and wear between the inertial block and the housing.
5. Silicone oil: Filled in the gap between the inertial block and the shock absorber housing, is the key medium for the shock absorber to achieve the damping function. Silicone oil has high viscosity, good stability and fluidity, and can effectively absorb and dissipate vibration energy.
6. Heat sink: Welded to the sides of the Silicone shock absorber 13068682 housing, mainly to increase the heat dissipation area, promptly dissipating the heat generated during the shock absorber’s operation, preventing the silicone oil from losing viscosity due to high temperature and affecting the shock absorption effect, and also serving a certain decorative function.

Silicone shock absorber 13068682 Working principle

• Torque vibration generation: When the engine is operating, due to the unevenness of the combustion process and the reciprocating motion of components such as pistons and connecting rods, the crankshaft will generate torsional vibration. When the natural frequency of the crankshaft system is close to the excitation frequency of the engine, resonance will occur, causing the torsional vibration amplitude of the crankshaft to increase, which may have a significant impact on the engine’s performance and reliability.
• Inertial lag: The housing of the Silicone shock absorber 13068682 is connected to the engine crankshaft, rotating and vibrating together. While the inertial block has a large rotational inertia, its movement always lags behind the movement of the housing. When the crankshaft undergoes torsional vibration, the rotational speed and direction of the housing will change rapidly, while the inertial block attempts to maintain its original movement state, thus generating relative motion between the inertial block and the housing.
• Damping shock absorption: The gap between the inertial block and the housing is filled with silicone oil. When they undergo relative motion, the silicone oil will generate viscous damping force. This viscous damping force can hinder the relative motion between the inertial block and the housing, converting the vibration energy of the crankshaft into internal friction heat energy of the silicone oil, thereby consuming the vibration energy and effectively suppressing the torsional vibration of the crankshaft, reducing the torsional vibration amplitude and avoiding resonance.

Silicone shock absorber 13068682 Performance characteristics

1. Good shock absorption effect: It can effectively reduce the torsional vibration of the engine crankshaft, especially in the resonance area of the engine. Compared with other types of shock absorbers, the silicone oil shock absorber 13068682 can significantly reduce the torsional vibration amplitude more significantly, improving the engine’s working stability and reliability.
2. Compact structure: The overall structure is relatively simple, occupying less space, and is easy to install on the engine, without causing too much impact on the overall layout of the engine, conducive to the optimization of the engine compartment space.
3. Reliable operation: Silicone oil has good chemical stability and thermal stability, maintaining good performance under different working temperatures and environmental conditions, not aging, deteriorating or leaking, resulting in a longer service life and higher reliability of the silicone oil shock absorber. Low maintenance cost: Due to the relatively simple structure of silicone shock absorbers, without complex mechanical transmission components, they do not require frequent maintenance and servicing during use. Only regular inspections of the appearance of the shock absorber for damage, leakage of silicone oil, etc. are needed, which reduces the usage cost.

Application fields of silicone shock absorber 13068682
