1. Definition and function of bearings
Bearings are mechanical components used in mechanical transmission to support rotating or swinging parts so that they can rotate flexibly around their axes or perform specific movements. Bearings play an important role in industries such as automotive, aviation, energy, manufacturing and agriculture, ensuring the smooth operation and efficient functioning of equipment and machinery.
Bearing function
1) Reduce friction: Bearings convert sliding friction into rolling friction through rolling elements, reduce the friction coefficient, reduce shaft rotation resistance, improve mechanical transmission efficiency, and reduce energy consumption.
2) High load level: bearings can withstand radial, axial and combined loads. Different types of bearings can be selected according to different application scenarios and load requirements.
3) Rotation accuracy guarantee: The bearing relies on precise manufacturing technology and reasonable structural design to ensure the position accuracy of the shaft during rotation and maintain a stable rotation center.
4)Guiding the direction of movement: Some bearings can guide the direction of movement of components. For example, linear bearings are used to achieve linear reciprocating motion and accurately guide sliders to slide smoothly on guide rails. They are widely used in automated production lines, CNC machine tools, etc. to ensure the accuracy and reliability of the linear motion of the equipment.
