What is a micro shaft
micro shaftThe structural design is an important step to determine the reasonable shape and overall size of the shaft and to design the shaft. It consists of the type, size and position of the parts installed on the shaft, the way the parts are fixed, the nature, direction, size and distribution of the load, the type and size of the bearing, the roughness of the shaft, the manufacturing and assembly process, the installation and transportation, and the alignment of the shaft. Deformation and other factors. Designers can be based onmicro shaftThe specific requirements of the design, and when necessary, several schemes can be compared to select the best design scheme.
The following are the general design principles of the micro shaft structure:
1.Save materials, reduce weight, and try to use cross-sectional shapes with equal strength or large cross-sectional coefficients;
2.Easy to accurately locate, stabilize, assemble, disassemble and adjust the parts on the shaft;
3.Take various structural measures to reduce stress concentration and increase strength;
4.Convenient processing and manufacturing to ensure accuracy.
micro shaftThe torsional stiffness check is the calculated torsional deformation of the shaft during operation, which is measured by the torsion angle per meter of shaft length. The torsional deformation of the shaft will affect the performance and working accuracy of the machine. For example, if the torsion angle of the internal combustion engine camshaft is too large, it will affect the correct opening and closing time of the valve; the torsion angle of the transmission shaft of the crane movement mechanism will affect the synchronization of the driving wheels. For shafts at risk of torsional vibration and shafts in control systems, greater torsional stiffness is required.
