Analysis of the Skills of the Launching Machine Sliding Bearing (1)

There are various types of sliding bearings used in launching machines, including bushings and bearing shells. These components play a critical role in ensuring the smooth operation and accuracy of the machine. The working clearance of these sliding bearings must be precise to prevent failure. The main causes of sliding bearing damage in launching machines can often be traced back to several factors, such as poor lubrication conditions, external disturbances that disrupt the oil film, or contamination from foreign materials. Common issues include improper installation, unclean parts, incorrect application methods, or chemical reactions that may occur during operation. According to an analysis by Cummins in the United States, four major factors contribute to sliding bearing damage: 1. **Contamination due to poor hygiene** – 45% 2. **Damage caused by lack of lubrication** – 25% 3. **Damage from improper application or equipment misuse** – 15% 4. **Damage from external factors such as chemical reactions or environmental stress** – 15% From this breakdown, it's clear that maintaining cleanliness is the most critical factor in preventing bearing failure. Ensuring clean parts during assembly, following proper maintenance procedures during operation, and protecting the machine from harsh environments—especially dust and chemicals—are all essential steps in extending the life of the bearings. The outer bearing alloy layer of the main bearing bush and connecting rod is the softest part and bears the highest load. This makes it more susceptible to damage. When wear or damage occurs on the bearing surface, it’s important to identify the root cause and address it promptly to avoid recurring issues. One common issue caused by poor hygiene is **wear from small particle contaminants**. For example, when the engine oil is drained, the first few drops may contain visible alloy particles. These tiny impurities can enter the bearing surfaces, leading to gradual wear over time. Even if no immediate damage is apparent, continued exposure can result in severe damage to both the bearing and the shaft. Therefore, timely cleaning and maintenance are crucial to prevent long-term harm. The abnormal wear caused by small particles is equivalent to normal wear over 2500 hours of operation, which significantly reduces the lifespan of the component. After repairs, the bearing’s service life cannot be predicted based on standard wear rates.

The headlamp is a kind of lighting tool worn on the head, mainly used to free the hands of lighting. The design of the headlights allows users to carry out various activities, such as night walking, camping, exploring, etc., without the need for hand-held lighting, thereby freeing up both hands for other operations. Headlamp is usually composed of headlamp body, charger, rechargeable battery, power socket and cable, etc., to provide stable lighting effect. The use of headlights is widely used, not only for outdoor activities, but also for some indoor activities, such as night reading, repair and so on.
When choosing a headlamp, there are several key factors to consider: brightness, irradiation distance, battery life, waterproof and dustproof ability. The ideal headlamp should have enough brightness to cope with different lighting needs, good irradiation distance to ensure safety, long battery life to meet the needs of long-term use, and a certain waterproof and dustproof ability to adapt to various environments. In addition, the type of headlamp battery is also an important consideration, you can choose a rechargeable or replaceable battery headlamp, according to the use of habits and needs to choose.
The brightness of the headlamp is usually measured in lumen, and the higher the lumen value, the higher the brightness of the lamp. Waterproof and dustproof rating is also an important indicator of headlamp performance, in general, IPX6 or above waterproof rating can meet the needs of most outdoor activities. When choosing a headlamp, you should also consider its light source type, such as LED, halogen or xenon, etc. Each light source type has its own unique advantages and disadvantages, and is suitable for different scenes and needs.
