The inner surface of the described accepting hole 52 of described cradle portion 5.
Again, the described assembly wall 612 of described bottom 61 is tapped using tool.It is specially：Tapped described using tool
Assembly wall 612 taps on described assembly wall 612 away from described connecting portion 63 towards the inner surface of described lower accepting groove 613, emphasis
Inner surface, force described assembly wall 611 forced expansion to extend out deformation, make the internal diameter of described lower accepting groove 613 become big, the most at last
Described assembly wall 612 is fixedly connected with described accepting hole 52 interference fit.Described bottom 61 clamping of so described bearing block 6
In the described accepting hole 52 of described cradle portion 5, will not loosen.Wherein, described tool is to beat appointing of described bottom 61
What instrument.Preferably, from one end of the described connecting portion 63 away from described bearing block 6 to the one end near described connecting portion 63,
The internal diameter of described accepting hole 52 is gradually reduced, so that described assembly wall 612 is clamped in described accepting hole 52.Specifically, institute
State the tapered setting of inner surface of accepting hole 52.
Then, described upper bearing (metal) 71 is pressed in the described upper accepting groove 623 of described upper end 62；By described lower bearing 72
It is pressed in the described lower accepting groove 613 of described bottom 61.It should be understood, of course, that, present invention additionally comprises installing described turning
The steps such as moving axis 3, in those skilled in the art's scope easy to understand, carefully do not state.
It should be noted that in other embodiments, first described lower bearing 72 can be pressed into described bottom 61
The described assembly wall 612 of described bottom 61 in described lower accepting groove 613, is then tapped again with tool.Here, described assembly wall
The outer surface of 612 inner surface and described lower bearing 72 is at intervals, i.e. the inner surface of described lower accepting groove 613 with
The outer surface of described lower bearing 72 at intervals, stretches in described lower accepting groove 613 in order to tool and taps described peace
Dress wall 612.Described lower bearing 72 can rely on described rotary shaft 3, in described lower accepting groove 613 glue coating or described assembly wall
Part that 612 are not tapped is realized and being fixedly connected of described rotary shaft 3 or described mounting seat 1.For convenience of dismantling, it is difficult to use
The part being tapped on described assembly wall 612 positions described lower bearing 72.In addition, described upper bearing (metal) 71 is pressed into described upper end 62
Step there is no special sequence requirement.
The motor of the present invention, the described cradle portion of described mounting seat and described bearing block split setting, described stator is permissible
It is sheathed on described bearing block from described bottom.The inner surface of described connection wall is from described connecting portion to described upper end direction
Projection fall in accepting groove on described, the outer surface of described connecting portion is from described connecting portion to the projection in described upper end direction
Fall in the outer surface of described upper end, on the premise of ensureing the thickness of described upper wall of described upper end, described upper end can
Not to be subject to the internal diameter restrictions of the described resettlement section of described stator, now, the internal diameter of described resettlement section can be less than described upper end
External diameter.Compared to existing design, the internal diameter of described upper accepting groove can be arranged to large scale, and then, corresponding described upper shaft
Hold and/or the described upper shaft part of described rotary shaft can also adopt large scale.Thus improving the overall impact resistance energy of described motor
Power.And, the described motor of the present invention is easily installed and significantly cost-effective, the 7 of prior art yuan cost can be dropped to 2 yuan
Left and right.Motor described in embodiments of the present invention, its described rotor is the described magnet steel of outside；Described stator is the described of the inside
Coil, described coil is fixedly linked with described mounting seat.In other selectable embodiments, described rotor can be the inside
Described coil, described stator be outside described magnet steel, described coil is rotatedly connected with described mounting seat；Or described coil
Outside as described rotor, described magnet steel is also feasible in the interior structure as described stator；Or described coil is made outside
For described stator, described magnet steel is also feasible in the interior structure as described rotor.
The foregoing is only the better embodiment of the present invention, protection scope of the present invention with above-mentioned embodiment is not
Limit, as long as the equivalent modification made according to disclosed content of those of ordinary skill in the art or change, all should include power
In protection domain described in sharp claim.
