Abstract
A spring motor for driving a driving shaft, comprising a spring operating gear; a spring about a rotation axis; a gear train; and a coupling arm connecting the rotation axis to the driving shaft by the gear train to transmit energy released by the spring from the rotation axis to the driving shaft, activating the driving shaft into rotation at a first speed. This spring motor allows storing energy in a spring; transmitting the stored energy to a driving shaft by linking an axis of the spring to the driving shaft by engaging the gear train; and reloading the spring; and reloading the spring by using a motor or transmitting energy from the driving shaft to the spring.
Claims13
A spring motor for driving a driving shaft, comprising:
- a spring operating gear;
- at least one spring about a rotation axis;
- at least one gear train;
- and
- a coupling arm;
- wherein said coupling arm connects said rotation axis to the driving shaft by said at least one gear train to transmit energy released by said spring from said rotation axis to said driving shaft, activating said driving shaft into rotation at a first speed.
A powering method, comprising:
- storing energy in a spring;
- transmitting the stored energy to a driving shaft by at least one gear train;
- and
- reloading the spring;
- wherein said transmitting the stored energy comprises linking an axis of the spring to the driving shaft by engaging said at least one gear train;
- and said reloading comprises at least one of:
- i) using a motor and ii) transmitting energy from the driving shaft to the spring.
