Abstract
Mechatronic spring drives with energy recovery based on pneumatic cylinders with return springs for stepping movements are investigated. In the food and pharmaceutical industries mechanic spring drives are used in conveyor lines and rotary tables of packing equipment. The nonlinear spring accumulators with an output rotary link are investigated. Mathematical models of a spring accumulator with spring reload are built. Comparative analysis of spring accumulators with an output rotary link with a spring reload and batteries without reload is carried out. It is shown that an increase in pretension leads to an increase in speed with a slight increase in size. In addition, it is found that an increase in the initial length of the pneumatic cylinder with a return spring also results in speed increase. The maximum values of the inertia moments for the rotary tables are determined for each standard size of a standard pneumatic cylinder with return spring, which can be moved by mechanic drives of this kind for a given turning time within one second. A mechanic spring drive has been designed for rotary tables of an automatic filli
