Rotating shaftThe structural design is an important step for the shaft design, which is to determine the reasonable shape of the shaft and all the dimensions of the structure. It is installed by the axis of the type of parts, size and location of the parts, the fixed way, the nature of the load, direction, size and distribution, the type and size of the bearing, the shaft of the blank, manufacturing and assembly process, installation and transport, on the shaft deformation and other factors. Designers can be designed according to the specific requirements of the shaft, if necessary, can do several schemes to compare, in order to select the best design, the following is the general axis structure design principles:

1,Rotating shaftSave material, reduce weight, as far as possible using equal strength contour size or large section of the cross-section of the shape of the coefficient;

2. Easy to locate, stabilize, assemble, disassemble and adjust the parts of the shaft;

3. Adopt a variety of structural measures to reduce stress concentration and improve strength;

4,Rotating shaftEasy to manufacture and ensure accuracy.

Rotating shaftBrief introduction of heat treatment:
Types of annealing: Full annealing and Isothermal annealing, also known as recrystallization annealing, generally referred to as annealing, this annealing is mainly used for the composition of a variety of carbon steel and alloy steel casting, forgings and hot-rolled profiles, sometimes also used for welding structure. Usually as the final heat treatment of some unimportant workpiece, or as the pre heat treatment of some workpieces. 2. Spheroidization annealing is mainly used for the analysis of carbon steel and alloy tool steel (such as manufacturing cutting tools, measuring, molds used in steel). Its main purpose is to reduce the hardness, improve the machinability of cutting, and prepare for later quenching. 3. Stress-relieving annealing is also called low temperature annealing (or high-temperature tempering), which is mainly used to eliminate residual stresses of castings, forgings, welded parts, hot-rolled parts, cold-drawn parts, etc. If these stresses are not eliminated, the steel parts will be deformed or cracked after a certain period of time, or in subsequent cutting processes.
