Become, respectively: starting motor, controlling organization, drive mechanism, wherein, start the motor power source as starting, being used for will
The electric energy of accumulator changes into an electromagnetic torque；Controlling organization drives engaging and dividing of gear and engine flywheel for controlling to start
From and start motor circuit break-make；Drive mechanism is for passing to an electromotor by a moment of torsion.
The patent documentation of Japanese Patent No. 2005-130753 discloses in prior art a kind of common starter (hereinafter referred to as
" prior art 1 ").As it is shown in figure 1, the output shaft 101 of this starter is defined in axial motion, the list in starter
Using axial static structures to clutch (hereinafter referred to as " isolator "), it can be around central rotation, but axial displacement is defined；
Having a hole, shell bearing 103 to be placed in this hole bottom isolator shell 102, it is outer that the end 116 of armature spindle 104 stretches into this
Columella holds in 103；Isolator inner shell 105 and output shaft 101 are overall as one.
The technological deficiency that this technical scheme exists is that isolator shell exists serious mistake orientation problem, including the first location (middle cover
106-middle cover bearing 107-output shaft 101-isolator inner shell 105-roller 108-isolator shell 102) and the second location (
Support lid 109-supports lid bearing 110-armature spindle 104-shell bearing 103-isolator shell 102).Particularly as follows: as in figure 2 it is shown,
The position of output shaft 101 is requirement center alignment as far as possible with the position of armature spindle 104, and output shaft 101 is by Front Cover Bearing 111 He
Middle cover bearing 107 supports, and solid line is its preferable rigging position；Armature spindle 104 outfan is supported by supporting lid bearing 110,
Armature spindle 104 is supported by bonnet bearing 112, and solid line is its preferable rigging position；During starter assembling, public owing to there is size
The reasons such as difference and fit tolerance, the position of bearing can be deviateed its preferable position, thus be caused output shaft 101 and armature spindle 104
The deflection put；As shown in Figure 2, it is assumed that Front Cover Bearing 111 position down offsets, and middle cover bearing 107 up offsets, at this moment output shaft
101 will deflect as the left-hand broken line in Fig. 2, are equivalent to output shaft 101 and are up moved by isolator shell；Meanwhile, support
Lid bearing 110 is toward moving down, and bonnet bearing 112 up moves, this time armature spindle 104 centrage such as the right side dotted line in Fig. 2
Deflecting like that, at this moment armature spindle 104 causes isolator shell toward moving down by shell bearing, and output shaft 101 is by isolator shell
Up moving, be so equivalent to create footpath internal force between output shaft 101 to armature spindle 104, namely isolator inner shell is deposited
Crossing orientation problem；Output shaft 101 is limited by Front Cover Bearing 111 and middle cover bearing 107, and isolator inner shell is due to defeated
Shaft 101 is an entirety, so its position is also defined, the amplitude that i.e. can regulate is the least, this footpath when there is location
Internal force is greatly increased, and this intensity that enclosure axis is held, supported lid bearing 110 and armature spindle 104 is the most unfavorable, accelerates
The abrasion of these parts, thus the life-span of starter can be reduced；So for reducing location adverse effect, it is necessary to improve
The machining accuracy of each correlated parts, is the most just greatly increased the cost of starter.
Additionally, cross location to also result in the smooth movement degree variation of decelerator.From the point of view of output shaft 101 to planetary gear pin 113,
The planetary gear pin 113 interfixed and the position of isolator shell 102 are positioned once, and this way from armature spindle 104,
The planetary gear pin 113 and the isolator shell 102 that interfix are positioned once by armature spindle 104 again, by the above-mentioned analysis crossing location
Understanding, when isolator shell 102 crosses location, isolator shell 102 necessarily gives one radial direction the biggest of armature spindle 104 end
Power, namely during retarder operation, sun gear 114 can produce under radial force effect and radially wobble.Thus will cause,
First, the swing of sun gear 114 causes each planetary gear 115 unbalance stress, so against " load of each planetary gear to the greatest extent may be used
Can be consistent " design object, the load causing some planetary gear 115 to load is less, and the load that some planetary gear 115 loads is very
Greatly, even result in its heavy overload, so accelerate the mill of the part such as planetary gear 115 and planetary gear axle bush (not shown)
Damaging or damage, the life-span of starter also can reduce；Second, the swing of sun gear 114 causes sun gear 114 and planetary gear 115
Engagement be deteriorated, thus noise during causing retarder operation increases or abnormal.
In order to avoid there is the mistake orientation problem of one way device for ignitor, the patent documentation of Patent No. CN 101328854B discloses
Another kind of common starter (hereinafter referred to as " prior art 2 "), this starter compared to the starter in prior art 1,
The location mode of its isolator shell is only: middle cover 201-middle cover bearing 202-output shaft 208-isolator inner shell 203-roller 204-
Isolator shell 205, i.e. eliminates " supporting and covering-support lid bearing-armature spindle-shell bearing-isolator in prior art 1
Shell " location mode, the location of isolator shell 205 is carried out only with middle cover 201.As it is shown on figure 3, in this starter
Isolator use axial static structures, it can be around central rotation, but axial displacement is defined, and isolator inner shell 203 has one
Hole, inner shell bearing 206 is placed in wherein, and armature spindle 207 end 216 (suggestion mark numeral) is by isolator shell 205
Bottom outlet, and stretch in inner shell bearing 206；As seen from Figure 3, output shaft 208 is by Front Cover Bearing 209 and middle cover bearing 202
Supporting, armature spindle 207 is supported by inner shell bearing 206 and bonnet bearing (not shown), solves in existing design with this
The problem that location crossed by the clutch existed.
Although " support lid-support lid bearing-armature spindle-shell the bearing-unidirectional eliminated in prior art 2 in prior art 1
Device shell ", only remain " middle cover 201-middle cover bearing 202-isolator inner shell 203-roller 204-isolator shell 205 ",
Avoid the mistake orientation problem of isolator shell present in prior art 1, but, with and create two new technology
Problem.
Present in prior art 2, first technical problem is: the positional precision of isolator shell 205 and planetary gear 210 is difficult to
Control.Owing to the location mode of " middle cover-middle cover bearing-output shaft-isolator inner shell-roller-isolator shell " relating to
Roller room and roller 204, and the tolerance relating to roller room and roller greatly and is relatively difficult to control, therefore, isolator shell 205
Positional precision is difficult to control to, and causes the planetary gear 210 being fixed on isolator shell 205 by planetary gear pin 211 further
Put precision to be difficult to control to.Describe in detail as follows:
As it is shown on figure 3, the position of planetary gear 210, start to calculate, through isolator shell 205, roller from planetary gear pin 211
Room profile, roller 204, isolator inner shell 203, middle cover bearing 202 are until middle cover 201, wherein, and the position of planetary gear 210
Put and related to roller room.Fig. 4 is the transverse sectional view of this one way device for ignitor, and as shown in Figure 4, roller room itself exists wheel
Wide form tolerance, and there is position of related features in the relative position between different roller rooms.Additionally, due to isolator shell 205
It is usually cold extrusion forming, there is bigger internal stress, carry out carburizing stiffened, internal stress and carburizing after cold extrusion forming further and all can
It is its areal deformation, strengthens aforementioned tolerance further.Further, along with the increase of the time of use, different roller rooms and the mill of roller
Damage situation differs.Therefore, the position of related features of planetary gear 210 is bigger, it is difficult to control, especially starter work a period of time it
After, because its abrasion condition differs, position of related features is further magnified, thus strengthens the skew of isolator shell 205 position.Base
In this, owing to planetary gear pin 211 is integrally fixed at bottom isolator shell 205, the position over-deflection of isolator shell 205,
Necessarily cause the position over-deflection of planetary gear 210.The over-deflection of planetary gear 210 position will cause: the first, sun gear 212
Swing cause each planetary gear 210 unbalance stress, so against " load of each planetary gear is the most consistent " design object,
The load causing some planetary gear 210 to load is less, and the load that some planetary gear 210 loads is very big, even results in it serious
Overload, so accelerates abrasion or the damage of the part such as planetary gear 210 and planetary gear axle bush, and the life-span of starter also can reduce；
The second, moment loss in transmitting procedure increases；3rd, the engaging of planetary gear 210 and sun gear 212 and ring gear 213
Being deteriorated, during causing retarder operation, produced noise increases or abnormal.
Present in prior art 2, second technical problem is: the unmanageable technical problem of air gap precision of starter.Due to
Prior art 2 eliminates " the supporting lid-support lid bearing-armature spindle-shell bearing-isolator shell " in prior art 1
Location mode so that the parts such as armature spindle 207, rotor core 214 need to be based in middle cover 201, middle cover bearing 202, isolator
Shell 203, inner shell bearing 206 complete location, and the dimension chain of position error is elongated, and air gap tolerance becomes big, particularly as follows: Fig. 5
The partial enlarged drawing in Fig. 3 at A, as it is shown in figure 5, relate to the part up to 7 of starter air gap, i.e. magnetic pole 215,
Rotor core 214, armature spindle 207, inner shell bearing 206, output shaft 208, middle cover bearing 202, middle cover 201, and each part
Between the place that cooperates more, in order to avoid rotor core 214 scratches magnetic pole 215, the gas that long dimension chain inevitable requirement is big
Gap size, big void dimension can reduce the output torque starting motor；Further, long dimension chain is easily caused relatively high tolerance, air gap
Relatively high tolerance can further result in the discordance of air gap and increase, thus cause the vibration of rotor to increase, vibration increases further
The noise causing starter increases, and service life shortens.
In view of this, how to design a kind of new starter, to eliminate drawbacks described above of the prior art and deficiency, be phase in the industry
Close the problem that technical staff is urgently to be resolved hurrily.
