主轴瓦：发动机平稳运行的核心保障        
       Crankshaft Main Bearings: The Core Assurance for Smooth Engine Operation

在现代内燃机中，曲轴瓦（也称主轴瓦）是确保发动机平稳、高效运行的关键部件。它们是发动机内部的“无名英雄”，支撑着曲轴的旋转，并最大限度地减少其与发动机缸体之间的摩擦。上海义豪汽配有限公司深知这些部件的重要性，致力于为广大客户提供高品质的沃尔沃（Volvo）和道依茨（Deutz）曲轴瓦，确保您的设备动力强劲，运行可靠。

In modern internal combustion engines, crankshaft main bearings (also known as main bearings) are critical components that ensure smooth and efficient engine operation. They are the "unsung heroes" within the engine, supporting the rotation of the crankshaft and minimizing friction between it and the engine block. Shanghai Yihao Auto Parts Co., Ltd. deeply understands the importance of these components and is committed to providing high-quality Volvo and Deutz crankshaft main bearings to our customers, ensuring your equipment delivers powerful and reliable performance.

曲轴瓦的作用与重要性        
       The Role and Importance of Crankshaft Main Bearings

曲轴是发动机的心脏，它将活塞的往复运动转化为旋转运动，从而驱动车辆或机械。主轴瓦则如同曲轴的“支点”，它们被安装在发动机缸体和轴瓦盖之间，精确地支撑着曲轴。它们的主要功能包括：

• 支撑曲轴：保持曲轴的正确位置，承受来自活塞和连杆的巨大冲击载荷。

• 降低摩擦：通过形成一层薄薄的润滑油膜，最大限度地减少曲轴与发动机缸体之间的金属接触和摩擦。

• 吸收振动：有效吸收发动机运行时产生的振动和冲击，保护其他关键部件免受损坏。

The crankshaft is the heart of an engine, converting the reciprocating motion of the pistons into rotational motion to drive vehicles or machinery. Main bearings act as the "pivot points" for the crankshaft, installed between the engine block and bearing caps to precisely support it. Their primary functions include:

• Supporting the Crankshaft: Maintaining the correct position of the crankshaft and withstanding immense impact loads from the pistons and connecting rods.

• Reducing Friction: Minimizing metal-to-metal contact and friction between the crankshaft and the engine block by forming a thin lubricating oil film.

• Absorbing Vibrations: Effectively absorbing vibrations and shocks generated during engine operation, protecting other critical components from damage.

优质的主轴瓦能够显著提高发动机效率，降低燃油消耗，并延长发动机的使用寿命。反之，磨损或损坏的轴瓦会导致一系列严重问题，如异常噪音、润滑不良、甚至发动机抱死，造成高昂的维修成本和停机时间。因此，选择原厂品质或高标准的替换件至关重要。

High-quality main bearings can significantly improve engine efficiency, reduce fuel consumption, and extend engine life. Conversely, worn or damaged bearings can lead to a range of severe issues such as abnormal noise, poor lubrication, and even engine seizure, resulting in high repair costs and downtime. Therefore, choosing OEM quality or high-standard replacement parts is crucial.
