ABSTRACT:
The present invention relates to a multi-axis type fans driven by magnetic force and its power transmission system for the same, wherein said power transmission system comprises a power source provided with a spindle, at least two driven shafts in different directions, and a magnetic transmission assembly located between each driven shaft and the power source. The magnetic transmission assembly includes a driving disc provided on the spindle, on the upper side of which are circumferentially equally spaced at least three permanent magnets; a driven disc provided at the end of respective driven shaft corresponding to the spindle, on the outer side of which are equally spaced permanent magnets the number of which is equal to that of permanent magnets on the driving disc and magnetism of which is as the same as those of corresponding permanent magnets on the driving disc, so when the driving disc is rotated by the power source, the permanent magnets thereon are also rotated, and each driven disc is driven to rotate under the mutual repulsion of the same poles of the permanent magnets while each driven shaft is driven to rotate to realize the object of power transmission of multi-axis. Due to no any contact between the permanent magnets, there is no any abrasion which causes the abrasion of the power transmission system to lower the cost of production.
