卷轮座 英语怎么说
卷轮座 (juan1 lun2 zuo4) is a Chinese term that refers to a type of bearing that allows rotational movement. In English, it is commonly called a “roller bearing.”
Roller bearings are used in a wide range of mechanical applications to support and reduce the friction of moving parts. They consist of cylindrical rollers that are held together by a cage or retainer and can be made from a variety of materials, including steel, ceramic, and plastic.
The concept of using rolling elements to reduce friction dates back to ancient civilizations, but the modern roller bearing was developed in the late 19th century by a British inventor named Frederick W. Lanchester. Lanchester’s design was based on the principles of ball bearings, but he used cylindrical rollers instead of balls to increase the load-carrying capacity of the bearing.
Here are some examples of how roller bearings are used in English:
The wheels of a car are mounted on roller bearings to allow them to turn smoothly.
Roller bearings are used in the driveshafts of many types of machinery, such as conveyor belts and gearboxes.
Roller bearings are an important component of many types of bearings, including tapered roller bearings, cylindrical roller bearings, and spherical roller bearings.
Examples:
The roller bearing on the door hinge was worn out, so it was difficult to open and close the door. (卷轮座在门铰链上磨损了，因此很难开合门。)
The roller bearings in the gearbox were replaced to reduce friction and increase the efficiency of the machine. (齿轮箱内的卷轮座被更换，以减少摩擦并进步机器效率。)
The roller bearings on the conveyor belt were lubricated to prevent wear and ensure smooth operation. (传送带上的卷轮座被润滑，以防止磨损并确保平稳运行。)
