Embodiment Construction
[0013] Below in conjunction with accompanying drawing, the present invention will be further described;
[0014] Such as figure 1 , figure 2 , image 3 As shown, the structure of a large-scale energy-storage scroll spring with reeds connected in series is as follows: the mandrels (3) of 1-N single-group scroll springs with the same structure are all provided with spline grooves, and spline grooves are all provided (mandrel 3 is Hollow mandrel, make a through hole along its axis, make spline groove on the hole wall), the intermediate shaft end of large vortex spring mandrel 8 is provided with 1-N splines, each flower key of the mandrel of single group vortex spring The keyway and the intermediate shaft end of the large scroll spring mandrel are assembled with 1-N splines correspondingly, so that the large scroll spring mandrel 8 is assembled with 1-N single-group scroll springs; the large scroll spring mandrel 8 is assembled with the large vortex spring case 6, the outer wa...

The invention discloses a reed series connection type large energy storage volute spring, which belongs to the field of energy storage and machinofacture. The structure of the reed series connection type large energy storage volute spring is as follows: spline grooves are arranged on mandrels of 1-N odd volute spring groups with the same structure, 1-N spinles are arranged on intermediate shaft ends of the large volute spring mandrels, spline grooves are assembled with corresponding splines, and therefore, a large volute spring mandrel is assembled with 1-N odd volute spring groups. The large volute spring mandrel is assembled with a large volute spring box, and the outer walls of the odd volute spring groups are assembled with the large volute spring box through screws. A mandrel of an N odd volute spring group tightly press a shaft sleeve, a mandrel of a first odd volute spring group is tightly installed with a locking nut together, and the right end of the large volute spring mandrel is provided with a shaft shoulder. The reed in series connection type large energy storage volute spiral spring has the advantages of 1 improving efficiency of installation, debugging and maintenance and saving amount of man power and material resources; and 2 increasing quality of stored energy.
Description
technical field [0001] The invention belongs to the field of energy storage and mechanical manufacturing, and in particular relates to a reed series-connected large-scale energy-storage scroll spring, which is applied to a large-scale mechanical elastic energy-storage device. Background technique [0002] Plane scroll springs are used in the fields of power drive and energy storage. In the structure of the current planar scroll spring, the shape of the reed is an Archimedes spiral, the outer end is fixed on the inner wall of the vortex spring box, the inner end is fixed on the mandrel, and the cross section of the reed is rectangular. The common planar scroll spring is formed by a group of reeds (single reed or multiple reeds) coiled in a plane. Compared with the thickness of the section, the width of the reed should not be too large, thus limiting the thickness of the reed. stiffness. The stored energy of the planar vortex spring used for large-scale energy storage needs ...
