          • Clockwork Storage ToolClockwork Storage Tool

              As lithium batteries won't store large scale energy This method is for storing renewable energy at large scales using Gravity :

              My machine solve several stage clockwork by avoiding connecting gears directly , however by discharging the energy in steps.

              in the picture 5 gears with spiral springs fixed to them gear #1 with no spring instead weight is used , gear #2 has the strongest spring , spring in gear #3 is weaker spring #4 is the weakest and that according to gear ratio gear #5 has no spring it is fixed to a generator

              How the machine works:

              group number 6 consisted of gear #2 and gear #4 , it moves from side to side continuously to transfer energy between the gears.When the group No (6) moves from right to left rod #8 will release gear #1 and at the same time small gear #2 will touch big gear #1, gear #1 will transfer some of its energy to weaker spring in gear #2, also at the same time small gear #4 will touch big gear #3, so that gear #3 will transfer some of its energy to weaker spring in gear #4.

              The opposite happens when the group No (6) moves from left to right:

              1) Rod #8 stops gear #1 to save energy.

              2) Big gear #2 will touch small gear #3 to transfer some energy to it and to be stored.

              3) Big gear #4 will touch small gear #5 to transfer its energy .

              As springs in the gears store limited amount of energy at each step I can use for instance 10 kilogram spring to store 300 Joules instead of 1 Kilogram , energy density of spring is 300J/Kg and that to increase maximum number of cycles before fatigue.

              methods for storing energy are weights going inside the ground or Helium balloons ; these ones go up with some lifting force to operate my clockwork, one meter cubic helium cost 3$ and can lift 1kg the good thing about helium balloons is that they can go up to very high heights making more Energy per Kilogram.

            • Externally-mounted Motorized PulleyExternally-mounted Motorized Pulley

                For externally-mounted motorized pulley, electric motor is removed out of the ordinary motorized pulley. And the pulley still with a retarding mechanism is often referred as a retarding drum. The motor is externally connected with the retarding drum to constitute an externally-mounted motorized pulley.
                The externally-mounted motorized pulley is a kind of conveyor driving device between the traditional open-type drive mode from motor to reducer then to the drive pulley and the common motorized pulley driving mode. Because of the external motor, it enjoys good heat dissipation performance and easy repair and replacement. It takes about one-third less than the open-type drive in occupying space and manufacturing materials.
                The externally-mounted motorized pulley is the product of the current industrial requirements. From the logic diagram, the main components are still connected in series, and at least one more drive shaft is needed. From the reliability, there is no increase in reliability. However, due to its good heat dissipation in the motor, convenience installation, maintenance and inspection of the motor, as well as its superiority in occupying space and manufacturing materials to the old open-type drive, the externally-mounted motorized pulley is usually used in high-power externally-mounted motorized pulley, and it is a suitable driving device in some high-power applications.
