Abstract
A magnetic damping device comprises a frame, a load wheel, two magnetic means, and a damping adjusting mechanism, wherein these two magnetic means have two arched plates that coaxially couple with each other by a connection shaft for synchronously adjusting the magnetic damping force. The damping adjusting mechanism has the structure for providing multi-sectional adjustment and for fine adjusting the magnetic damping force so as to provide the product with stable and uniform quality. As a result, the product can be maintained and tested easily.
Claims3
A magnetic damping device comprising:
- a) a frame;
- b) a load wheel;
- c) a magnetic device having:
- i) two arched plates including a first arched plate and a second arched plate, each of the two arched plates has a plurality of magnets located thereon;
- and
- ii) a connection shaft connected to the frame, a first end of the first arched plate and a first end of the second arched plate are pivotally connected to the frame by the connection shaft;
- and
- d) a damping adjusting mechanism having:
- i) a rotation shaft being rotatable between first and second positions;
- ii) a rotation plate fixed on the rotation shaft;
- and
- iii) two adjustable rods, a second end of the each of the two arched plates is adjustably connected to the rotation plate by one of the two adjustable rods, a first rod end of each of the two adjustable rods is pivotally connected to the rotation plate, a second rod end of each of the two adjustable rods is pivotally connected to a second end of one of the two arched plates,
- wherein, when the rotation shaft rotates between the first and second positions, the rotation shaft rotates the rotation plate, the rotation plate controls a movement of the two adjustable rods, the two adjustable rods selectively moving the two arched plates inwardly and outwardly thereby selectively adjusting a size of a space located between the plurality of magnets and the load wheel, wherein each adjustable rod of the two adjustable rods comprises:
- a) two connection rods, a first connection rod of the two connection rods has a rod end having first rod threads wound in a first direction and a second connection rod of the two connection rods has a rod end having second rod threads wound in a second direction opposite the first direction;
- and
- b) a dual-side nut located between the two connection rods and having a first threaded nut end having first nut threads corresponding to the first rod threads and a second threaded nut end having second nut threads corresponding to the second rod threads,
- wherein a length of each adjustable rod is selectively lengthened and shortened by rotating the dual-side nut.
