The inner both sides of permanent magnet 50 have parting of baffle bolt 67 to be clamped on flange bracket 109 by magnet baffle plate 32, press closer screw 19 and radial screw bore 18 rotatable engagement, and pass through radial screw bore 18 by permanent magnet 50 tightening firmly, security insurance more.
Committed step:
(1) bending resistance component 80 is installed
By the component for adjusting ring 82 on bending resistance component 80 and nearly outer end place, the Front Cover Bearing hole 24 on front end housing 20 interference fits, and match with the protecgulum screw 27 on front end housing 20 with the component pillow hole 85 that component screw 28 passes through on bending resistance component 80, component flange 87 on bending resistance component 80 is close to fixing with the protecgulum concave station face 29 on front end housing 20, makes the rotational clearance 48 having a millimeter between rotating shaft overhanging section of 46 outlines of the component inner bore of step 84 on bending resistance component 80 and machine shaft 40.
(2) needle roller outer ring 69 is installed
First sprocket wheel adjusting ring 92 matched in clearance being put among the sprocket wheel stepped hole 96 on output chain gear 90 and crossing sprocket wheel escape 93 is attached on sprocket hole bottom surface 95; Again needle roller outer ring 69 interference 0.01 millimeter on NA type separate type needle bearing 60 is coordinated among the sprocket wheel stepped hole 96 on press-in output chain gear 90, again sprocket hole snap ring 91 specific purpose tool is put into sprocket wheel draw-in groove 98, make both sides, needle roller outer ring 69 against sprocket hole snap ring 91 and sprocket wheel adjusting ring 92 respectively.
(3) needle roller inner ring 68 is installed
Needle roller inner ring 68 is placed in 200 degree of machine oil the outer bearing be placed on bending resistance component 80 that heats up for 3 minutes to prop up and hold round on 89, members shaft snap ring 86 specific purpose tool is put into component annular groove 81, makes needle roller inner ring 68 both sides against members shaft snap ring 86 and component escape 83 side shaft shoulder respectively.
(4) connection between output chain gear 90 and machine shaft 40
By the needle roller outer ring 69 be fixed on output chain gear 90 together with bearing needle be inserted in be fixed on outer bearing prop up hold round on 89 needle roller inner ring 68 part, slowly rotate output chain gear 90, sprocket wheel splined hole 94 on output chain gear 90 is aimed at the axle head spline 49 on machine shaft 40 match, continue pushing output chain gear 90, the bearing needle on needle roller outer ring 69 is matched completely with needle roller inner ring 68;
First take after step backing-up screw 74 passes through axial location back-up ring 70 centre bore and match with the axle head screw 47 on machine shaft 40, on the two flat side bumpers shoulder caps 73 of axial location back-up ring 70 on step backing-up screw 74 and axle head spline 49 outer face between have one millimeter axially freely to measure;
Match with the sprocket wheel end face screw 97 on output chain gear 90 pass through the positioning retainer ring through hole 76 on axial location back-up ring 70 again with five back-up ring screws 77 after, axial location back-up ring 70 is also fastened on output chain gear 90 outer face;
Also match with the sprocket wheel end face screw 97 on output chain gear 90 after finally passing through the through hole on locking catch 71 and the positioning retainer ring through hole 76 on axial location back-up ring 70 successively with a back-up ring screw 77, on any flat limit that catch corner edges 72 on locking catch 71 is aimed on two flat side bumper shoulder caps 73, play and loosen effect.
Install.
(5) run
When the motor is energized, the moment of torsion that electromagnetic force produces is by the axle head spline 49 on machine shaft 40, and the sprocket wheel splined hole 94 on output chain gear 90 passes to the multiple chainwheel tooth 99 on output chain gear 90, realizes moment of torsion and exports.
And chain produce radial load react to output chain gear 90 be can completely bear by needle bearing 60, only act on bending resistance component 80, radial load is born in the rotating shaft avoided on machine shaft 40 for overhanging section 46; Owing to meeting under the prerequisite of rated power, can accomplish that the limit is little by asking the diameter of machine shaft 40 in design, only bearing pure torsion, simultaneously, because bending resistance component 80 global shape belongs to hollow short tube, therefore structural rigidity is superpower, can bear larger radial load.Both combine, and that whole motor size can be done is compact, can bear larger radial load again, run more reliable, thus extend the useful life of motor.
The present invention has following outstanding substantive distinguishing features and significant progressive effect:
Due to the inner face of front end housing 20 and rear end cap 30 being fixedly connected with the first stator 52 and the second stator 51 respectively, and the first stator 52 and the second stator 51 lay respectively at the both sides of rotor field spider, be exactly when original single stator single rotor, add stator module, become Double-stator motor, be the equal of just two motor parallel work, thus significantly improved power and without dilated diameter.
By arranging cooling water built-in pipe water channel in front end housing 20 and rear end cap 30, the heat taken away in the unit interval is air-cooled two to three times, and refrigeration is better.
Cooling water built-in pipe 88 pre-buriedly again casts in motor housing 10 cylinder position for the 316L stainless steel tube with high-temperature stability is shaping in advance, and omnidistance without any seam, current are unimpeded, are not easy dirt.
Rotational clearance 48 is had between the component inner bore of step 84 of bending resistance component 80 and the rotating shaft of machine shaft 40 overhanging section 46, the outer bearing of bending resistance component 80 props up and holds round the endoporus that 89 are fixed wtih the needle roller inner ring 68 on needle bearing 60, the cylindrical of the needle roller outer ring 69 on needle bearing 60 is fixed on sprocket wheel stepped hole 96 inner round wall of output chain gear 90, sprocket wheel stepped hole 96 bottom surface of output chain gear 90 has the axis for spline tooth circumferential engagement between sprocket wheel splined hole 94 and the axle head spline 49 on machine shaft 40 slidably coordinate.Said structure design achieves a transmitting torque between machine shaft 40 and output chain gear 90, and the moment of flexure load on output chain gear 90 is be delivered on bending resistance component 80 by needle bearing 60 completely.
Bending resistance component 80 entirety adopts high strength zinc alloy Steel material, possesses good rigidity resistance to deformation.
Table 1 be present invention employs bending resistance square component fore bearing 25 after 80s fore bearing section 45 radius run-out degree (micron) of machine shaft 40 of fixing with do not adopt the fore bearing 2 of the constant power motor of bending resistance square component 80 the experimental data of fore bearing section 45 radius run-out degree (micron) of machine shaft 40 of fixing compare.
The data of the radius run-out degree (micron) at (table 1) fore bearing section 45 position compare
Contrasting data from table 1 can draw: it is after 80s that fore bearing 25 outer end have employed bending resistance square component, load suffered by fore bearing 25 alleviates wearing and tearing and reduces, cause fore bearing 25 the radius run-out degree (micron) at fore bearing section 45 position of machine shaft 40 of fixing more stable.
Outside component flange 87, outer bearing props up the axiality relation holding round and have Pyatyi tolerance grade between 89 and component for adjusting ring 82 cylindrical, guarantees that machine shaft 40 and output chain gear 90 also have axiality relation, realizes output chain gear 90 steadily coaxial rotating.
Motor front end cover arranges bending resistance component, and shared all moment of flexure loads, made machine shaft only bear pure torsion, the machine shaft diameter under equal-wattage can reduce half, finally realizes motor entirety and has breakthrough compact.
