The article deals with calculation of a stair lift drive and its design. The aim is the determining the necessary power of the used electric motor depending on the variable input values such as a passenger weight, a gradient of the seat lift etc. Calculating the required power for operation of the equipment is essential for selecting the optimal drive motor. In practice, the mathematical-physical principle of solving a problem such as drive calculation is often neglected. This results in the use of excessively powerful propulsion equipment, and thus in excessive financial cost in mass production. Consequently, by designing a drive-train, it will be possible to design the entire drive mechanism, i.e. motor, gearbox, gear module, etc. A significant part of the overall solution will be the design of the shaft for the drive pinion and its analytical dimensional calculation in comparison with the numerical solution. This will fulfil the prerequisites for optimizing the current shaft design by reducing its mass from the current value of 1.185 kg while the safety and reliability conditions of the construction are still met.
