What does the structural design of the shaft include?
The design of the shaft structure is mainly to determine the shape and size of shaft. In general structure design condition: assembly drawing machine, shaft speed, transmission power, shaft parts of the main parameters and dimensions.
Strength and stiffness of 13.2.1 axisThe strength of the shaft is related to the magnitude and nature of the work stress. The following aspects should be noted when selecting the structure and shape of the shaft1. make the shape of the shaft close to the equal strength condition2., avoid the sudden change of shaft sections to reduce the local stress concentration3. change the layout of the parts on the shaft and sometimes reduce the load on the axle4. improve the structure of the shaft parts can also reduce the load on the shaftThe fixation of the 13.2.2 parts on the shaft1. weeks to the fixed (key, spline, pin and interference fit, etc.)2. axial fixation (shoulder, collar, nut, sleeve and shaft end ring positioning etc.)
The name of each paragraph on the axisThe shaft structure and shape depends on the following factors: (1) axis of the blank type: (2) axis force size and distribution; (3) the nature and the connection method of fixed position, with the shaft parts; (4) the type, size and position of the bearing; (5) processing method shaft assembly method and other special requirements. Many factors that affect the structure and size of visible axis, to various factors comprehensively consider the design of shaft.
