Description
Technical field
The present invention relates to Mechanical & Electrical Transmission field, particularly to a kind of Surface Mount for normal axis transmission-Halbach array formula
Permanent-magnet surface gear train.
Background technology
The transmission of normal axis at present more uses bevel gear dough-making powder gear.The tooth surface shape of bevel gear is complicated, and processing and manufacturing is stranded
Difficulty, the bevel gear parameter of different brands is the most different, and many employing pairings manufacture in manufacturing process, this processing to bevel gear
Manufacture, overhaul and keep in repair and cause very burden.The roller gear that the tool dimension that face gear needs due to processing engages with reality
Identical, the number of cutters required for the face gear of processing different size and parameter is more, and processing cost is higher；It addition, face gear
Inner radius has Undercutting Phenomenon, outer radius to have wedge angle phenomenon, and therefore the facewidth can not be designed to oversize, and transmission intensity is limited.
In the last few years, the magnetic gear relying on magnetive attraction to carry out power transmission has a great development.Magnetic gear can
Realize contactless transmission, it is to avoid driving shaft contacts with the direct mechanical of driven between centers, can reduce noise and vibration, to work
Environmental nonpollution, and there is the features such as overload protection.
According to the feature of bevel gear dough-making powder gear, people is had correspondingly to propose the permanent-magnet planar being capable of normal axis transmission
Gear and permanent magnetism conical gear.The permanent-magnet planar gear using the coupling of multi-turn magnetic pole have employed a fairly large number of permanent magnet, structure
More complicated, assembling trouble；The permanent magnet of permanent magnetism conical gear magnetize mode and assembling the most relatively difficult.
Summary of the invention
The invention aims to solve to be currently used for the permanent-magnet planar gear of normal axis transmission and bevel gear structure is multiple
Problem miscellaneous, that manufacture and assemble difficulty, it is provided that a kind of Surface Mount for normal axis transmission-Halbach array formula permanent-magnet surface tooth
Wheels.
Realizing above-mentioned purpose, the present invention adopts the technical scheme that:
A kind of Surface Mount for normal axis transmission-Halbach array formula permanent-magnet surface gear train, its composition includes two wheels, described
Two wheels be magnetic gear, two wheel be respectively cylinder wheel and face wheel, described face wheel is horizontally disposed with, described circle
Post wheel is arranged on above face wheel, and cylinder wheel is mutually orthogonal with the axle centre of face wheel, stays between cylinder wheel and face wheel
There is air gap；When one of them is taken turns as drivewheel, another one wheel for driven pulley, described drivewheel by magnetive attraction drive from
Wheel rotation.
The present invention provides the benefit that relative to prior art:
1, due to cylinder wheel and face wheel there is no direct Mechanical Contact, this gear train without abrasion, noise is little, transmission efficiency is high,
There is the advantages such as high, non-maintaining, the overload protection of reliability；
2, due to tight in the spacing between the first type tile shape permanent magnet and the Second-Type tile shape permanent magnet being often disposed adjacent
Close it is provided with a tile shape filler body so that the consumption of permanent magnet is greatly decreased, and cost is reduced；
3, use Halbach array formula that permanent magnet is installed and can produce higher air-gap field, therefore the performance of gear train is had
Bigger lifting.
To sum up, the simple in construction of this gear train, compact, convenient for assembly, it is adaptable to noise, cleanliness factor and reliability requirement
Higher and that two axle systems are mutually isolated occasion.
