Title:
MULTI-AXIS TYPE FANS DRIVEN BY MAGNETIC FORCE AND POWER TRANSMISSION SYSTEM FOR THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/009381
Kind Code:
A1
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.
