Any technician who dedicates himself or wants to dedicate himself to mechanical design will, sooner or later, face the design of an axle, also called a shaft in mechanical jargon. Axles are very commonly used elements to transmit rotational movements (and, therefore, mechanical power) between parts, such as gears, pulleys, wheels, etc., which is why practically all mechanisms with circular movement contain one. It is therefore essential to know the appropriate techniques and methodology to obtain a correct design in the shortest time possible . The use of advanced three-dimensional modeling software, such as Solid Edge (SIEMENS) , will be of great help for this. 3D design, essential today Nowadays the mechanical design of machines is increasingly carried out using specific three-dimensional modeling software , so we are going to show how we can use one of these 3D computer-aided drawing programs to obtain the axis we want. It is evident that we must previously collect the necessary information regarding the number of supports on the axis, as well as the elements that are mounted on the axis and between which we wish to transmit the circular movement. The most common thing is that the shaft supports are made using bearings (ball, cylinder, etc.) or bearing supports.
These are mounted on the shaft through a certain adjustment, but it is highly recommended to take additional precautions to prevent their axial displacement, for which Belarus Email List auxiliary elements such as fixing nuts, threaded rings, fixing plates, covers or rings are used. elastic. diseno_3d_con_solid_edge_1 Fig.1.- Simple ball bearing. As for the elements that carry the circular movement and the corresponding mechanical power, they are also usually mounted with a certain adjustment combined with a key. In this way, the integral rotation of this element with the shaft and the adequate transmission of the driving torque is ensured . As we mentioned before, its axial movement must be limited through the use of auxiliary interfaces similar to those used with bearings, such as shoulders, elastic rings or other common accessories. All this implies having different sections or sections with different diameters on the axis to house the different mechanical components. These sections must be appropriately designed to mount the corresponding auxiliary fixing interfaces . As we can see, the shaft design process becomes complicated, especially when it must also be verified that the shaft will be able to withstand the mechanical stresses (traction, compression, bending, fatigue, torque) to which it will be subjected during its normal operation.
It is therefore very helpful to use 3D modeling software that makes the design process as easy as possible. Next, we are going to show the Engineering Reference utility of Solid Edge , a powerful parametric program for computer-aided design of 3D three-dimensional parts and assemblies. This software makes five completely different work environments available to the user : Piece, Sheet, Assembly, Welding and Drawing. The Engineering Reference utility can be found in both the Part and Assembly environments, in the “Tools” window and allows the design of axes, cams, spur and bevel gears, worm screws, rack-pinion transmissions, gear wheels , compression springs, extension springs, pulleys, beams and columns. diseno_3d_con_solid_edge_2 Fig.2.- Engineering Reference utility drop-down window. By choosing the “Axis Designer” option, the dialog box opens in which we must begin to enter the necessary information to define the geometry of the axis to be designed.
