“…Friction losses in the guides are reduced if the springs are located in a vertical plane and above the guides. In the particular case, when the condition e = mg / c is fulfilled, the load from the moved mass is balanced by the vertical component of the spring force throughout the entire working displacement [12]. At the same time, the energy costs of the engines to compensate for dissipative losses are reduced.…”

Mechanical spring drives with energy recovery are designed to produce return-rotational movements in various technological equipment and reduce energy costs by several times compared with traditional electromechanical, hydraulic and pneumatic drives. The use of pneumatic motors in spring drives to compensate for dissipative losses, fixing the drive in extreme positions and the primary charging of spring batteries is considered. The class of tasks in which spring drives with energy recovery are created using only pneumatic cylinders with return springs is highlighted. This study examines mechanical spring drives with energy recovery, based on nonlinear spring batteries with spring preload in the middle position of the output link. The use of pneumatic actuators with return springs in mechanical drives based on linear spring batteries with two springs is proposed. Mechanical spring drives with energy recovery are designed to produce return-rotational movements in various technological equipment and reduce energy costs by several times compared with traditional electromechanical, hydraulic and pneumatic drives. The amount of energy expended in spring recuperative drives is actually determined by the energy expended on compensating for dissipative losses in kinematic pairs. The results of the study allow the designers of such drives to consciously approach the choice of their schemes and design parameters.

The use of pneumatic cylinders with return springs in mechanical drives with reusable energy for reusable and continuum movements, fixing the output link in the extreme positions are considered. A defined range of work operations can be used by these cylinders. The use of pneumatic actuators with return springs in mechanical drives based on linear spring batteries with two springs is proposed. Algorithms for compensating dissipative losses in mechanical spring drives are considered. The maximum mass values that can be moved by such mechanical drives for each size of the pneumatic cylinder are determined. It is proposed to use pneumatic cylinders with return springs in mechanical drives with energy recovery based on nonlinear spring batteries. A mechanical spring drive for unwinding rolls of packaging materials with discrete modes. In tasks of reciprocating movement of objects with a controlled stand in extreme positions, the reduction of energy costs is achieved when using mechanical spring drives with energy recovery. Energy costs can be reduced several times. Traditionally, a spring-loaded drive contains a linear or nonlinear spring-loaded battery, a control system, controlled clips and a motor to compensate for dissipative losses. The use of electric motors to compensate for dissipative losses is also limited by low speed, as compensation for dissipative losses occurs throughout the displacement and with high speed increases engine power and requires transmission with a large gear ratio.

Рассмотрены нереверсивные шаговые приводы с пружинным аккумулятором, позволяющие снизить энергопотребление при выполнении технологических процессов. Рассмотрены кинематические схемы компоновки шагового привода, выбраны оптимальные конструкции управляющих узлов и разработана экспериментальная установка нереверсивного шагового привода с рекуперацией энергии. Испытания, проведенные с помощью экспериментальной установки нереверсивного шагового привода, позволили сравнить ранее полученные теоретические данные с экспериментальными. Проведен сравнительный анализ временных показателей пневматического шагового привода и привода с рекуперацией энергии. Полученные результаты показали, что применение пружинного аккумулятора позволяет значительно снизить энергетические затраты. Применение пружинного привода экономически выгодно в промышленной сфере.
