Abstract
The utility model relates to a rotor of a permanent magnet flywheel generator, which comprises a magnetic shoe (1), a magnetic shoe base (2), an external rotary frame (3) and a belt pulley (4). The utility model is characterized in that the belt pulley (4) and the external rotary frame (3) form separated structures. The belt pulley (4) is a circular ring of which the cross section forms a V shape, and the external rotary frame (3) is a circular ring of which the cross section forms an L shape. The diameter of the internal circle of the belt pulley (4) is matched with the diameter of the external circle of the external rotary frame (3). The external rotary frame (3) is sheathed in the belt pulley (4) in a concentric way, and the external rotary frame (3) and the belt pulley (4) are fixed into a whole through a connecting piece. As the rotor with the structure can adopt steel plates as raw materials and is produced by the processing way of stamping and stretching, the productive efficiency of the rotor is greatly raised, and the self weight of the rotor is reduced. In addition, when the rotor is installed, half-round head screws with smaller end diameters can be adopted, and a dummy club portion of a flywheel is not required to reduce and can be installed directly.
Description
Technical field: the utility model relates to a kind of permanent magnetism fly-wheel generator rotor.
Background technology: the permanent magnetism fly-wheel generator rotor structure generally includes magnetic shoe, magnetic shoe seat, changes frame and belt pulley outward, together being fixed on ring-type after magnetic shoe is installed on the magnetic shoe seat changes outward on the medial surface of frame, the outer frame that changes generally adopts cast iron to form through cut, and on periphery, process " V " shape groove and constitute belt pulley simultaneously, so production efficiency is low, from great, material cost and processing cost height; In addition, need flywheel boss part diameter car is little, to adapt to the termination of the sunk screw that is used for installing.
Summary of the invention: the purpose of this utility model be for overcome the deficiencies in the prior art provide a kind of in light weight, cost is low, the permanent magnetism fly-wheel generator rotor that production efficiency is high.
For achieving the above object, the utility model adopts following technical solution: the permanent magnetism fly-wheel generator rotor, comprise magnetic shoe and magnetic shoe seat, change frame and belt pulley outward, it is characterized in that: described belt pulley is the branch body structure with the outer frame that changes, described belt pulley is the V-shaped annulus in cross section, outer commentaries on classics frame is the annulus that the cross section is " " shape substantially, and the interior circular diameter of belt pulley matches with the outer frame outside diameter that changes, and described outer commentaries on classics frame concentric locking collar is located in the belt pulley and by connector and fixedly fuses.
The rotor of said structure, because can adopt steel plate is raw material, produce with the punching stretch processing mode, therefore production efficiency increases substantially, deadweight has also alleviated many, and can adopt the less button-headed screw of termination diameter when installing, need not that partly the diameter car is little with the flywheel boss, can directly install.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings:
Accompanying drawing 1 is the utility model embodiment cross-sectional structure schematic diagram.
Embodiment: as shown in Figure 1, the permanent magnetism fly-wheel generator rotor comprises magnetic shoe 1 and magnetic shoe seat 2, changes frame 3 and belt pulley 4 outward, belt pulley 4 is the branch body structure with the outer frame 3 that changes, described belt pulley 4 is the V-shaped annular member in cross section, outer change frame 3 is " " shape substantially for the cross section annular member, the interior circular diameter of belt pulley 4 matches with outer frame 3 outside diameters that change, and describedly changes that frame 3 concentric locking collars are located in the belt pulley 4 and is fixedly fused by connector such as screw or rivet 5 outward.Magnetic shoe seat 2 is made ring-type by epoxy resin or plastics, external diameter matches with outer frame 3 internal diameters that change, its ring is gone up the suitable groove of uniform some and magnetic shoe 1, magnetic shoe 1 is arranged in the described groove cross section of being made by non-magnet material such as aluminium sheet in the outside and pushes down for the pressure ring 6 of " L " shape, and is connected outer the commentaries on classics on the frame 3 by screw or rivet 7 and is integral.
Claims (3)
1, a kind of permanent magnetism fly-wheel generator rotor, comprise magnetic shoe (1) and magnetic shoe seat (2), change frame (3) and belt pulley (4) outward, it is characterized in that: described belt pulley (4) is the branch body structure with the outer frame (3) that changes, described belt pulley (4) is the V-shaped annulus in cross section, outer commentaries on classics frame (3) is the annulus of " " shape substantially for the cross section, the interior circular diameter of belt pulley (4) matches with outer frame (3) outside diameter that changes, and described outer commentaries on classics frame (3) concentric locking collar is located in the belt pulley (4) and by connector and fixedly fuses.
