Abstract
The utility model relates to a rare-earth permanent-magnet motor rotor of an additional wheel net type, which is provided with a magnetic conducting core body manufactured by ferromagnetic materials, permanent magnets and a protecting ring. The utility model is characterized in that the magnetic conducting core body is a ring shape, wherein, the diameter of an inner hole of the magnetic conducting core body is matched with the outer diameter of a driven wheel. The outer part of the magnetic conducting core body is provided with a non-ferromagnetic barrier frame of a net shape, wherein, the non-ferromagnetic barrier frame of a net shape is provided with a groove and the permanent magnets manufactured by rare-earth permanent-magnet materials are embedded in the groove. The permanent magnets are arranged in pairs, and the magnetic conducting core body, the permanent magnets, the protecting ring and the barrier frame of a net shape are mutually fixedly connected. After the inner hole of the magnetic conducting core body is matched with the driven wheel, a permanent-magnet rotor integrated with a driven device is formed, a support mechanism of the rotor is saved, and the entire structure of the driven device is simplified.
Description
A kind of additional felloe type rare-earth magneto-electric machine rotor, it belongs to a kind of rotor of special (type) motor, can be used for the driving of large-sized low-speed rotating machinery: as winch, oil-well rig etc.
As the motor of modern industrial equipment drive unit, all be the version that is designed to have a style of one's own, use output shaft to link to each other with driven device, in most equipment, also need to use various deceleration devices.Adopt such method,,, have a style of one's own, thereby also need to increase the self-supporting etc. of motor rotor, increased the complexity that structure is set because motor is separately design and install though can make the function singlenessization of each module of equipment.
The purpose of this utility model is to invent a kind of special rotor bearing that do not need, and with the additional rim type rare-earth permanent magnet motor rotor of driven equipment one, it can simplify the structure of whole driven device.
Shown in the structure accompanying drawing 1 of the present utility model, magnetic conductive core 1, permanent magnet 2, retaining ring 3 that it has ferromagnetic material to make, it is characterized in that: magnetic conductive core 1 is a diameter of bore and be driven the annular that the wheel external diameter matches, the netted shelf 4 that has groove is arranged in magnetic conductive core 1 outside, netted shelf 4 uses non-ferromagnetic system to make, in the groove that netted shelf 4 is opened, be inlaid with the permanent magnet 2 that uses rare earth permanent-magnetic material to make, permanent magnet 2 mounted in pairs, magnetic conductive core 1, permanent magnet 2, retaining ring 3 and netted shelf 4 are affixed mutually.
Accompanying drawing 1 is a structure cutaway view of the present utility model.
Accompanying drawing 2 is a drawing in side sectional elevation of the present utility model.
In the utility model, the permanent magnet 2 that uses rare earth permanent-magnetic material to make is bar shaped.
In the utility model, magnetic conductive core 1 is to use the ferrimagnet manufacturing of high magnetic conduction, as mild steel, pure iron, silicon steel etc., the closed magnetic resistance of the magnetic line of force of permanent magnet inside is reduced, the endoporus of magnetic conductive core 1 just in time cooperates with driven wheel shaft, can use the form transfer torque of stationary fit, also can use the form transfer torque of key or other securing member.
Magnetic conductive core of the present utility model is the annular of band endoporus, its endoporus be driven wheel and match after, form a p-m rotor with the driven device one, saved the supporting device of rotor, simplify the structure of whole driven device.
In the utility model, the two sides, front and back (inside and outside) of the permanent magnet 2 that rare earth permanent-magnetic material is made is two magnetic poles.When mounted, the permanent magnet of on the rotor symmetric position, installing 2 just in time opposite to outer magnetic pole, the magnetic by magnetic conductive core 1 connects, and forms a pair of rotor magnetic pole, makes rotor have the magnetic circuit character of integral type p-m rotor.In the permanent magnet 2 that embeds, how right can have, and the external pole polarity of adjacent several permanent magnets 2 is identical, forms the rotor magnetic pole scope of a broad, can match with the magnet pole widths that the stator winding coil produces.Permanent magnet 2 can a plurality of one group of arrangement, and the pole orientation between group is opposite, forms multisegmented rotor (as four utmost points, sextupole, the ends of the earth, so that more multipole), satisfies the needs of different rotating speeds.
In the utility model, the strip permanent magnet 2 of rare earth material manufacturing can use the Nd-Fe-B series rareearth magnetic material, also can use cerium cobalt based material.Permanent magnet 2 can be an integral body, also can be to make fritter to be spliced along its length.Such magnet has more versatility, for the rotor of different length, only need be spliced just by the fritter magnet of different numbers.
Netted shelf 4 in the utility model should use the nonferromugnetic material manufacturing, as stainless steel, aluminium alloy, titanium alloy, and various nonmetallic materials.Its effect is to keep permanent magnet 2 to be in definite position, to avoid rotor permanent magnet 2 stressed generation displacements when working.
Retaining ring 3 in the utility model also uses the nonferromugnetic material manufacturing, also can use stainless steel, titanium alloy and as nonmetallic materials such as fiberglass.The effect of retaining ring 3 is to protect rotor when high speed rotating, and strip permanent magnet 2 is not subjected to action of centrifugal force and throws away, thereby certain intensity requirements should be arranged.
Magnetic conductive core 1 in the utility model, permanent magnet 2, and mutual affixed of retaining ring 3 and netted shelf 4 can use various securing members to connect, as bolt, rivet, welding etc., and their mixing.The form that also can adopt plastic bonding to solidify is bonded as one above-mentioned part as using epoxy resin, solidifies then, forms an integral body, can bear higher centrifugal force, is used for high rotational speed.
