[0002] The gearbox lubrication system is a system used to protect and maintain the normal operation of the gearbox, which is usually composed of a lubricating oil tank, an oil pump, a filter, a lubricating pipeline, a lubricating oil cooler, connecting pipelines, etc. The gearbox is usually used to transmit power and torque, and is widely used in many mechanical equipment, such as industrial machinery, ships, etc. The gears, bearings and other moving parts inside the gearbox work under high-speed rotation and high load, so good lubrication is required to reduce friction, wear and heat, thereby extending the life of the equipment and ensuring its normal operation;

[0003] In the lubrication system, the gear pump draws the lubricating oil from the oil tank through the pipeline, passes through the oil filter and cooler, and then flows back to the oil tank through the intermediate pipe. This cycle is repeated to ensure the quality of the equipment's lubricating oil and enable the equipment to work normally. The traditional piping system has a single function. For example, if all pipes are used for connection and there are cold welds, the vibration generated when the machine is running and the flow of oil will cause the pipeline to rupture, causing certain risks and increasing costs. In addition, it is inconvenient and troublesome to replace the hard pipe. If a hose is used for connection, although it can ensure the convenience of installation and replacement, and it has better adaptability to complex environments, the hose has a low service life and is not pressure-resistant. Once damaged, it will cause great losses and troubles.
