. The application performance of seals in large excavators For large excavators, we usually see that they are very powerful and very hard. It feels that the whole is made of steel, and it is difficult to imagine its components. It is supported by many rubber seals in order to complete those coordinated and heavy excavation work. In fact, rubber seals are widely used in the engines of large machines. Many people may think that the power transmission mode of the engine is driven by steel gear chains. This is very wrong. Most engines transmit power in the same way. It is carried out by the transmission belt in the rubber seal. This kind of transmission method is incomparable with the chain in terms of the transmission efficiency of kinetic energy and the coordination of transmission. Let us explain in detail the use of rubber seals in large-scale rubber seals. Application performance in excavators. There are many types of rubber seals for excavator engine damping pads, and rubber seals damping pads have been widely used in the field of engine vibration and noise reduction due to their small size, low cost, and easy adjustment of elasticity and stiffness. Therefore, the current bulldozer diesel engine supports almost all use vibration damping rubber. The use of rubber vibration damping in the support parts has high requirements on the joint surface, and also pays attention to high temperature resistance and no oil corrosion. Not only pay attention to the vibration isolation when the diesel engine rotates at high speed, but also pay full attention to the vibration isolation of the diesel engine when it is idling, starting and stopping, and preventing the resonance of each part of the body. Shock absorber structure Vibration damping rubber working temperature: -30 ~ 60 ℃; maximum amplitude of vibration load: 270KN; load frequency: 012 ~ 200Hz; main load action frequency: 4 ~ 8Hz. For small amplitude vibration loads, the shock absorber can absorb more than 80% of the vibration energy; and for shock loads, it can dissipate more than 50% of the impact energy. Application effect on crawler guide wheel Taking the rubber shock absorber installed at the guide wheel of a crawler bulldozer as an example, the installation position of the rubber shock absorber is shown, and its shape is shown. The function is to buffer vibration in both vertical and horizontal directions. It can be seen from the above description that rubber seals are mainly reflected in kinetic energy transmission, buffering and shock absorption, and oil sealing in large excavators. These aspects are enough to reflect the important position of rubber seals in large machine structures. Tai'an City Gaobang Machinery Parts Co., Ltd. specializes in the production of rubber seals.
