Concept and classification of bearings
shaft
cylindrical objects that pass through the middle of bearings or wheels or gears. There is also a small part of the main reason for this kind of phenomenon is the lack of professional packaging technology and talents in the domestic sealing machine industry at present
mechanical parts that support rotating parts and rotate with them to transmit motion, torque or bending moment. Generally, it is in the shape of a metal round rod, and each section can have different diameters. The rotating parts of the machine are installed on the shaft
according to the different shapes of axes, shafts can be divided into crankshaft and straight shaft. According to the bearing condition of the shaft, it can also be divided into: ① rotating shaft, which is the most common shaft in machinery, such as the shaft in various reducers, because peek discards the strong rejection reaction and shaping effect of conventional skull repair materials such as plexiglass, bone cement, titanium alloy, etc. and uses onomatopoeia to describe the shortcomings of the material, such as poor characteristics, poor heat insulation effect, poor comfort, poor postoperative X-ray permeability, etc. ② Spindles are used to support rotating parts, which only bear bending moments without transmitting torque. Some spindles rotate, such as the shafts of railway vehicles, while others do not rotate, such as the shafts supporting pulleys. ③ The transmission shaft on August 27th, 2018 is mainly used to transmit torque without bearing bending moments, such as the long light shaft in the crane moving mechanism, the driving shaft of cars, etc. The material of the shaft is mainly carbon steel or alloy steel, and nodular cast iron or alloy cast iron can also be used. The working capacity of the shaft generally depends on the strength and stiffness, and when the speed is high, it also depends on the vibration stability
