Spring drives for reciprocal motion

详细

Problems were considered concerning energy consumption decrease in spring drives, with the use of nonlinear spring accumulators provided by guides, unloading at mid position, depending on the carriage mass with a working body. The value of the axis offset of the spring fixation providing the lack of loading on the guide along its entire length was determined. Potentials of the drive self-locking in extreme positions without driven fixing rods were shown. Friction losses in the elements of the nonlinear spring accumulator were determined. A fivefold decrease of the dissipation losses for optimum size of accumulator as against the linear spring accumulator was shown.
