The anti-attrition noise reducing mechanism of projecting end assembling includes graphite antifriction sheet 8, spring leaf 9 and the poly-ammonia being arranged on from inside to outside on axle 5
Ester pad 10.
In described step (a), each casing 4 rivets bearing 4012, in order to by bearing 4012 supporting rotor
Axle 5, described bearing 5 can be copper-base powder metallurgy bearing；Specifically, casing 4 uses small-sized press, join riveting tool riveting
Copper-base powder metallurgy bearing, riveting back cabinet 4 surface without scuffings, defect, bearing surface without weighing wounded, riveting trace without exception, bearing and
Between casing 4 seamless, it is possible to the axial force bearing more than 300N does not loosens, comes off, casing pole pawl 43 inwall without scratch, hair
Thorn.The bearing 4012 of riveting can play the effect of the axle 5 supporting rotor, also functions to reduce rotor rotation process axis 5 and axle
Hold the abrasion between 4012.
In described step (a), the preparation process of coil block 3 is as follows:
(1) coil injection skeleton, in injection moulding process, leaves spliced eye in its end；Specifically, coil rack uses note
Moulding technique to make, coil rack need to be molded full, nothing incompleteness, and spliced eye is left in end；
(2) contact pin 300 is squeezed into spliced eye；Specifically, being fixed on by coil rack in contact pin frock, pin machine is by contact pin
300 squeeze in pin holes, and contact pin 300 insert state is intact, without few contact pin 300, contact pin 300 without bending, coming off, different in size,
Contact pin 300 axial tensile-strength is more than 10N；
(3) coiling on coil rack, forms coil case；Specifically, by coil rack centre bore and coil winding machine locating shaft
Alignment is inserted in, and starts coil winding machine and coil rack carries out coiling and doubling operation, and doubling is highly not more than 2.1mm, and doubling completes
Rear coil winding machine works automatically, and coil-winding completes.Guarantee on each coil rack, there are two groups of coilings, and coil tested,
Coil must not have open circuit and Inter-turn Short Circuit Phenomenon.
(4) coil case need the position warding off stannum ward off stannum；Specifically, the coil case that will ward off stannum is enclosed within frock, and
Guarantee that coil case is put into put in place, utilize the location structure of frock, it is ensured that coil rack keeps fixing after being inserted in frock, it is impossible to turn
Dynamic；Coil rack starts after being in place wards off stannum machine, wards off stannum machine and automatically wrapping post is warded off stannum, by contact pin 300 and winding
The line in face becomes an entirety, wards off after stannum completes and takes off coil, and after warding off stannum, the tensile strength of contact pin 300 is more than 7N；Due to
Stannum pot is exposed to for a long time in air and can produce oxide layer, and during carrying out warding off stannum, often warding off 24 coil cases will be by stannum pot
The stannum of surface layer is removed, and wards off the stannum degree of depth well, and most 2 astragals do not ward off stannum, the most deeply may not exceed skeleton boss face；Must not there is skeleton
Without bad orders such as scalds；
(5) to the coiling position insulation processing on coil case；Specifically, coil case is enclosed within Brush-painter and loads onto, in frock
Locating slot blocks the contact pin portion of coil case.In cup, appropriate insullac is dipped with special brush, will not be the most continuous with insullac
Whereabouts is as the criterion.Starting mopping frock motor so that it is drive coil case slowly to rotate, brushing with brush does not has the coil table of insullac
Face.Coil case one Zhou Junneng is clearly visible the blue paint of coating, and adheres to outside skeleton without significantly paint, and increase is played in mopping
Coil insulation, fixed coil enamel-covered wire eliminate motor electromagnetic noise.
Being located by connecting and being located by connecting between lower casing and lower middle pole plate between above upper casing and upper middle pole plate
