The material standards and working principles of self-lubricating
bronze bushings are as follows:
Material standards:
Self-lubricating bronze bushings are usually made of bronze alloys, such as CuZn24Al6 high-strength brass, or other bronze alloys such as CuSn6Zn6Pb3 (6-6-3 tin bronze), etc. These materials have good mechanical properties and wear resistance, and can withstand certain loads and friction.
Working principle:
The working principle of self-lubricating bronze bushings is to add a special lubricant to the bronze sleeve to form a lubricating film in the motion friction, thereby reducing the direct friction between the contact surfaces and improving the operating efficiency and life of mechanical parts.
The working principle of self-lubricating bronze bushings can be divided into two processes:
1. Lubricant transfer: In the self-lubricating bronze sleeve, the lubricant is added to the microscopic pores on the surface of the bronze sleeve. When the mechanical parts start to move, due to the action of friction, the lubricant will gradually transfer from the inside of the bronze sleeve to the surface of the bronze sleeve, forming a continuous lubricating film.
2. Lubricating film formation: When the lubricant reaches the surface of the bronze sleeve, due to the action of friction and surface tension, the lubricant will form a uniform lubricating film on the contact surface. This lubricating film can withstand the load of mechanical parts, while reducing the friction coefficient between contact surfaces, reducing wear and energy loss.
Self-lubricating bronze bushings have the following advantages over ordinary bronze bushings:
1. Reduce friction and wear: By forming a lubricating film, self-lubricating bronze bushings can effectively reduce friction and wear between mechanical parts, improve operating efficiency and life.
2. Excellent self-lubricating performance and wear resistance: Able to work stably under low friction, high temperature and high load environment.
The above information is for reference only. The specific material standards and working principles may vary depending on different application environments and requirements. In actual applications, it is recommended to select the appropriate self-lubricating bronze sleeve material and design according to the specific situation.
