The APM Bear module is easy to use, and this can be seen in the organization of input data. All geometric dimensions of the bearing can be entered manually, or you can use the database that is part of the APM WinMachine system. The database includes the standards used in Russia, at the same time it is available for editing. Accuracy parameters at the request of the user are selected using the database for a given accuracy class.
The loads acting on the bearing can be arbitrary, while the preload force can also be considered as an external load. The preload value, depending on the type of bearing, is specified either in the form of an applied axial (radial) load or in the form of radial (axial) movements.
For the case when the external loads acting on the shaft change over time, there is a specialized graphical editor with a full set of functions necessary for entering variable parameters.
