Abstract
The present invention is a kind of under-water Nd-Fe-B permanent magnet motor, belongs to electromechanical equipment.The present invention makes motor pole by rare earth permanent-magnetic material-neodymium iron boron, and has waterproof static seal and dynamic sealing device.The present invention can be used for making main drive motor in the machinery such as ocean robot, and the motor power output that adopts the present invention to make exceeds 1 times than external like product, and electric efficiency improves 50%.
Description
The present invention is a kind of under-water Nd-Fe-B permanent magnet motor, belongs to electromechanical equipment.
At present, the motor that is used in the world under water generally is an electro-magnetic motor, in recent years.Advanced country adopts the ferrite permanent-magnet motor.Above-mentioned two kinds of motors or volume are big, heavy, and perhaps power output is little, and efficient is low.Be used for underwater exploration, in the devices such as photography, make device complicated heavy, give operation under water, research work is brought very big difficulty.
The purpose of this invention is to provide that a kind of volume does not increase and under-water Nd-Fe-B permanent magnet motor that power output doubles.Electric efficiency improves 50%.
The present invention realizes with following technical scheme: the present invention adopts the third generation rare earth permanent-magnetic material-neodymium iron boron of superpower magnetic to make motor pole, the permanent magnet ndfeb thin slice of the superpower magnetic of space mounting polylith in less motor, its fastening structure and process are that special interpolar aluminium block is fastened on the motor case, two interpolar aluminium blocks are pressed into the neodymium iron boron magnetic body piecemeal in the dovetail groove then at casing inner wall formation-dovetail conduit.At this moment, magnetic patch radially and tangentially all is being fixed.Axial restraint is by special interpolar locking aluminium block.In magnetic patch is pressed into dovetail groove, during assigned position, the locking aluminium block is fixed tightly on the interpolar aluminium block with screw, thus between magnetic patch and the motor case radially, tangentially, all be fixed on axial three directions.When solving strong magnetic pole mounting technology problem, also to solve the waterproof sealing problem that motor is worked under the deep water operating mode.Motor is worked under the deep water operating mode and promptly will be solved the static sealing of motor; Solve the dynamic seal (packing) of motor again.The sealing device of motor under deep water by static seal device under water and under water dynamic sealing device form.Static seal device is that the static seal lid is housed at the back end cover for motor place under water, in the seal groove of static seal lid sealing ring is housed.In quiet close postoperculum hole, stationary seal ring is housed.In static seal lid front hole, the sealing retaining ring is housed, rotary packing ring is equipped with at stationary seal ring place at the static seal postoperculum, spring is housed in the spring base, rotary packing ring contacts with spring and is contained in the spring base, lining cooperates with spring base, and in the spring base of packing into, sealing ring is housed at lining and rotary packing ring place.In lining and seal groove that motor shaft contacts, sealing ring is housed.Spring base, lining is fastening by securing member with hoop.
The present invention has that volume is little, and power output is big, efficient height, the outstanding feature that water resistance is good.
Now in conjunction with the accompanying drawings the present invention is described in further detail.
Fig. 1 is the main cutaway view of looking of the present invention.
Fig. 2 is vertical view of magnetic pole fastening structure schematic diagram of the present invention.
Fig. 3 is the transverse views of magnetic pole fastening structure schematic diagram of the present invention.
Fig. 1～3rd, specific embodiments of the invention.The present invention adopts third generation rare earth permanent-magnetic material one neodymium iron boron of superpower magnetic to make motor pole, by the technological requirement of the relatively large motor of assembling.Its magnetic pole 7 is made up of the thin piece of permanent magnet ndfeb of the superpower magnetic of polylith.Its fastening structure and process are that special interpolar aluminium block 26 is fastened on the motor case 6, and two interpolar aluminium blocks 26 form a dovetail conduit at casing inner wall.Then the neodymium iron boron magnetic body piecemeal is pressed into dovetail groove.Magnetic patch radially and tangentially all is being fixed.Axial restraint is by special interpolar locking aluminium block 4.During the position of in magnetic patch is pressed into dovetail groove, stipulating, locking aluminium blocks 4 are fixed tightly on the interpolar aluminium block 26 with screw 27.Like this between magnetic patch and the motor casing 6 radially, tangentially, all be fixed on axial three directions.Front end housing 1 is fastened on the casing 6 by securing member, in front end housing 1 and casing 6 contact positions sealing ring 2 is housed, motor fore bearing 24 is housed on the front end housing 1, commutator 3 and armature 8 are housed on the electrode axis 5, in motor shaft 5 front loaded fore bearings 24 holes, rear end cap 9 is fastened on the casing 6 by screw, and rear bearing 23 is contained on the motor shaft 5 and embeds in the rear end cap 9.In the static seal lid 12 sealing ring 22 is housed, sealing retaining ring 11, sealing ring 10 is fastened on the rear end cap 9 with securing member then, and stationary seal ring 13 static seal of packing into is covered in the 12 rear portion circular holes, embeds sealing ring 21 again.After spring 19 is packed in the spring base 15, lining 16 cooperates with spring base 15, rotary packing ring 14 is packed in the spring base 15, with rotary packing ring 14, spring base 15, lining 16 are packed on the motor shaft 5, and rotary packing ring 14 is contacted with stationary seal ring 13.Lining 16 is equipped with sealing ring 20 with rotary packing ring 14 contact positions, in lining 16 and motor shaft 5 contact positions sealing ring 18 is housed.Hoop 17 is fastened on lining 16 by securing member, on the spring base 15.Kuppe 25 is contained in the motor front portion.
The present invention compares with present same kind of products at abroad, and power output increases 1 times in the situation that does not increase volume, and electric efficiency improves 50%.
