Once the installation and disassembly sequence of the components on the shaft is established, the overall shape of the shaft is typically determined. The general order follows: first, the central rotor section is installed, then it is placed into the housing. After that, the bearing end cap is added, followed by the bearing and the outer bearing housing. Finally, the pulley and flywheel are attached to both ends of the shaft.
The diameter of each segment of the shaft depends on the load it will bear. However, during the initial design phase, the exact location of the support forces and the distribution of bending moments are usually unknown. As a result, the main shaft diameter cannot be directly calculated based on the actual load or the resulting stress. Instead, the torque acting on the main shaft can often be estimated early in the design process. Therefore, the initial diameter of the shaft is typically determined based on the torque it will transmit. At this stage, the minimum diameter found is noted, and then the diameter of each individual segment is gradually defined according to the assembly plan and positioning requirements of the main shaft.
In addition, the diameters of the shaft segments must meet specific standards, especially for critical parts such as bearings and standard components. These sections should use the corresponding standard diameters along with the appropriate fit tolerances. This ensures compatibility and proper function within the system.
Determining the length of each segment of the shaft involves balancing compactness with the need for sufficient space for assembly and adjustment. The axial dimensions of each mating component, as well as the necessary clearance between adjacent parts, must be considered. Since the general dimensions of the rotor, flywheel, and pulley have already been designed, the overall length of the shaft can also be roughly estimated at this stage.
