Description
Technical field:
The present invention relates to a kind of permanent magnetism without a speed changer, in particular to a kind of multiple groups for being close permanent-magnet stepless variable-speed device.
Background technique:
Permanent-magnet stepless variable-speed device refer on the same axis two magnetic flexibles (one be permanent magnetism circle, one be induction coil), one
A to be mounted on line shaft, one on load axis.Two circles can mutually be inserted in, exit by driver chuck, push and revolve in power source
Turn lower and generate different magnetic coupling areas, transmits the kinetic energy used enough and speed.Here it is the stepless changes of single group (one group) permanent magnetism
Fast device.Only has single group permanent-magnet stepless variable-speed device at present.The contact area of two magnetic flexibles has determined torque magnitude.Magnetic force (torsion)
Size and magnetic flexible surface area or direct ratio.Magnetic flexible surface area is bigger, and magnetic force is stronger, then weak on the contrary.If torsion reaches tens of thousands of
Ox, magnetic flexible must be at huge monsters.So two magnetic flexible contacts area of single group permanent-magnet stepless variable-speed device are small, therefore torsion has
Limit.It needs the gear of large torque mechanical many at present, such as large truck, steamer, train (rail locomotive), needs torque number
Thousand to ox rice up to ten thousand, and single permanent-magnet stepless variable-speed device is can not to can solve rhetoric question topic.
Summary of the invention:
Taking up space in order to overcome the above shortcomings, it is an object of the present invention to provide one kind, small and torsion is big, energy-efficient multiple groups are closed forever
Magnetic stepless transmission.
The object of the present invention is achieved like this:
Multiple groups of the present invention close permanent-magnet stepless variable-speed device, including cabinet, the output shaft loaded on cabinet, at least one input shaft, dress
In at least two main shafts parallel to each other by the axial line of input shaft drive respectively on cabinet, every master is corresponded on cabinet
It is respectively provided on the position of transmission shaft and corresponding main shaft coaxial inner conductor and outputs power to the slave drive on output shaft
Axis, on every main shaft equipped with permanent magnetism circle, it is corresponding with every main shaft from transmission shaft equipped with respect to being inserted in or exit
The induction coil of permanent magnetism circle, on each induction coil equipped with driver plate, one end and driver plate connect and the other end pass through corresponding main shaft or
It corresponds to from the driver plate speed-changing pull rod outside transmission shaft axle center hole outlet.
Loaded in cabinet corresponding sides, main shaft from transmission shaft is respectively two for above-mentioned input shaft, output shaft coaxial inner conductor
Root, main shaft are parallel to input shaft, output shaft axial line from transmission shaft axial line, and the driver plate that one end is connect with induction coil becomes
The other end of fast pull rod passes through main shaft axle center hole and stretches out outside cabinet, and two main shafts pass through transmission mechanism respectively and inputted
Axis drives, and two pass through transmission mechanism from transmission shaft respectively and power is input on output shaft.
Above-mentioned input shaft is two, and main shaft is two and is attached separately on corresponding input shaft that one end and driver plate connect
The other end of the driver plate speed-changing pull rod connect passes through to correspond to be stretched out outside cabinet from transmission shaft axle center hole, and two pass through respectively from transmission shaft
Power is input on output shaft by transmission mechanism.
Above-mentioned input shaft is one, and main shaft is three.
Above-mentioned input shaft is one, and main shaft is four.
Multiple groups of the present invention close permanent-magnet stepless variable-speed device compared with single permanent-magnet stepless variable-speed device it is advantageous that,
One, the occupied space area of the equipment largely saved.This is for movable machinery, automobile, locomotive, and steamer is particularly important.Core is latent
Ship, tank are more important.Magnetosphere occupied space area are as follows: 50x50 × 2=5000 square centimeter.Two 50Cm circles, than 100Cm magnetic
Enclose the area of few occupied space 1/2.If enclosed with 10Cm, ten circle magnetic surface products are enclosed with 100Cm, but occupied space area only has 10
× 10x10=1000 square centimeter.Only the 1/10 of 10000 square centimeters, space utilization rate is high, has very much to transmission operation machinery
Benefit；
Two, large torque magnetic gear shift can be made, from hundreds of kilograms, several tons become tens kilograms.To processing, assembly, maintenance is all
It brings convenience；
Three, the linkage of multi-speed exchanged device can energy conservation.Torsion in movable machinery starting and traveling differs 3 one 10 times.Load variations
There may be several times~decades of times.Single speed changer is difficult to adapt to such variation.Multi-joint speed change can be logical by standard-sized sheet, partly opens
General solution is determined.
