Below, second compound gear 40 and second compound gear, 40 included ratchet mechanisms 100 are elaborated.Fig. 3 is an exploded perspective view of observing the part of second compound gear 40 shown in Figure 2 from the top of covering 4 (with reference to Fig. 1) side.
As shown in Figures 2 and 3, second compound gear 40 with second gear 41, second small gear 42, ratchet component 110 on coaxial each other assembling constitute.
Thereby ratchet component 110 is installed on the embedding part 143 of second small gear 42 to be linked with second small gear 42, but ratchet component 110 and second small gear, 42 one are provided with rotatably.
Second small gear 40 comprises the ratchet mechanism 100 that the engaging tooth 122 by the engaging pawl 113 of ratchet component 110 and second gear 41 constitutes, second gear 41 and second small gear 42 carry out one rotation (coupled condition) or rotation (off state) relatively by above-mentioned ratchet mechanism 100 according to sense of rotation.
Fig. 4 is the plan view of observing from the top of cover plate 5 sides the state after second gear 41, second small gear 42, ratchet component 110 assemblings.
For example, second small gear 42 with respect to second gear 41 when counterclockwise rotating, engage with the teeth groove 122c of engaging tooth 122 with the pawl 113 that engages of the ratchet component 110 of second small gear one rotation, thereby make the rotation of second small gear 42 and second gear, 41 one, and when when clockwise direction rotates, the front end 112a side of the arm 112 of ratchet component 110 is towards rotating center O side resiliently deformable, after engaging pawl 113 slides on the 122b of the plane of inclination of engaging tooth 122, fall into the teeth groove 122c of engaging tooth 122, make the front end 112a side of arm 112 return to the outside of rotating center O, repeat above-mentioned action, thus second small gear 42 and the 41 relative rotations of second gear.
Fig. 5 (a) is a plan view of observing ratchet mechanism 110 from cover plate 5 (with reference to Fig. 1) side, and Fig. 5 (b) is the A-A sectional view of Fig. 5 (a).
In the central authorities of main part 111, the embedding hole 115 that the embedding part 143 (with reference to Fig. 2) of confession second small gear 42 embeds runs through main part 111 and is provided with on thickness direction (rotating center O's is axial).
Embedding hole 115 is formed with two the planar surface portion 115a parallel to each other with the cross-sections match of embedding part 143, link the ratchet component 110 and second small gear 42 if embedding part 143 is embedded embedding hole 115, then ratchet component 110 links rotatably with second small gear, 42 one.
Shown in Fig. 5 (b), on the upper surface 111b of aftermentioned cap 150 (with reference to Fig. 2) side of main part 111, on the full week of outer periphery, form with equal height towards the outstanding outstanding wall 114 in cap 150 sides top.
Under the state after second compound gear, 40 assemblings shown in Figure 2, since ratchet component 110 be arranged in supporting axle S3 axially on have a little loosening, therefore when ratchet component 110 during towards cap 150 side shiftings, by only will giving prominence to wall 114 and cap 150 butts, thereby reduce the area of contact of ratchet component 110 and cap 150.
This be because: compare when the slip resistance of ratchet component 110 when rotating center O rotates all contacts with cap 150 with the upper surface 111b of main part 111 and reduce.
As shown in Figure 5, arm 112 extends, begins from the position of leaving outer circumferential face 111a predetermined distance along outer circumferential face 111a around counterclockwise extending towards radial outside from the outer circumferential face 111a of main part 111.
Among the inner peripheral surface 112c of main part 111 sides of arm 112, to be positioned at rotating center O be on the imaginary circle Ima at center for the part of removing front end 112a side and cardinal extremity 112b side, among arm 112 and outer circumferential face 112d main part 111 opposition sides, the major part of removing front end 112a side and cardinal extremity 112b side is positioned at imaginary circle Ima concentric and diameter than on the big imaginary circle Imb of imaginary circle Ima.
Therefore, the radial width W from the arm 112 of end on observation forms with identical width in the most scope of removing front end 112a side and cardinal extremity 112b side.
By cantilever support, the front end 112a side of arm 112 is a fulcrum with the cardinal extremity 112b that is connected with main part 111 to arm 112 on main part 111, can be towards main part 111 side resiliently deformables.
Therefore, among the Fig. 4 that observes from cover plate 5 sides, if the input make ratchet component 110 with respect to second gear 41 around right handed rotation torque, then as shown in Figure 5, the front end 112a side that ratchet component 110 makes arm 112 in the figure with the main part 111 side displacements shown in the arrow α, thereby Yi Bian can make engaging pawl 113 go up slip with the plane of inclination 122b of the engaging tooth 122 shown in the double dot dash line in the drawings to rotate around clockwise direction.
From the end on observation of rotating center O, pointed engaging pawl 113 extends towards radial outside.Engaging pawl 113 does not take place at arm 112 under the state of resiliently deformable, and is more outstanding by radial outside towards the outer circumferential face 112d than arm 112 with the length that engages with the teeth groove 122c of engaging tooth 122.
Therefore, as shown in Figure 4, when engaging pawl 113 is positioned on the position with the plane of inclination 122b butt of engaging tooth 122, the front end 112a side of arm 112 is in all the time towards the state of the main part 111 side resiliently deformables of radially inner side, and engaging pawl 113 is in the reaction force that produced by above-mentioned resiliently deformable and towards the state of the engaging tooth 122 side application of forces of radial outside.
Therefore, when ratchet component 110 when clockwise direction rotates because engaging pawl 113 slides on the 122b of the plane of inclination of engaging tooth 122, on one side so ratchet component 110 bear the braking force corresponding and be rotated with acting on the active force that engages pawl 113.
As shown in Figure 5, main part 111 circumferentially is provided with three arms 112 around rotating center O.The circumferential lengths L1 of each arm 112~L3 forms with different respectively length, make ratchet component 110 when clockwise direction rotates when making arm 112 resiliently deformables, the engaging pawl 113 of the front end of each arm 112 does not fall into the teeth groove 122c interior (with reference to Fig. 4) of engaging tooth 122 simultaneously.
This be because: if engaging pawl 113 all falls into teeth groove 122c simultaneously, then almost produce simultaneously,, do not fall into simultaneously, then can suppress noise by making it from becoming very big noise because of falling into the noise that causes.
In addition, as the circumferential lengths L1 of each arm 112~when L3 is equal length, even that the relation between the quantity of the quantity that will engage pawl 113 and engaging tooth 122 is made as is relatively prime, that is to say that the quantity with engaging tooth 122 is made as 1 such relation with the greatest common divisor of the quantity that engages pawl 113, can make the engaging pawl 113 of the front end of each arm 112 not fall into simultaneously in the teeth groove 122c of engaging tooth 122 too.
In addition, in mode of execution, at least on the part of engaging pawl 113, be coated with lubricating grease as the toughness oiling agent, owing to utilize this lubricating grease, not only can prevent to engage the wearing and tearing of pawl 113 and engaging tooth 122, and the viscous resistance of lubricating grease can bring braking to arm 112 mobile, impact and noise in the time of therefore slowing down engaging pawl 113 and fall into teeth groove 122c.

The opening diameter D2 (with reference to figure (8) b) that the outer diameter D 1 of perisporium 121 is configured to than aftermentioned cap 150 is slightly little, as shown in Figure 2, in assembling during second compound gear 40, the state with in the chimeric wall portion 152 that perisporium 121 is embedded in cap 150 rotatably is provided with second gear 41.
As shown in Figure 6, in containing room 120, surrounding wall 124 courts that surround the inserting hole 123 of central authorities give prominence to and are provided with perisporium 121 equidirectionals.
Surrounding wall 124 apart from the height h2 of the bottom surface 120a of containing room 120 at the complete identical projecting height of Zhou Shangwei, as shown in Figure 2, this height setting becomes, under the state that is assembled with second compound gear 40, between the lower surface 111c of the main part 111 of the upper end of surrounding wall 124 124a and ratchet component 110, guarantee that micro gap is arranged.This be because: if surrounding wall 124 is contacted with main part 111, then when ratchet component 110 rotates, can form resistance.
Shown in Fig. 6 (a), on the inner peripheral surface of the rotating center O of perisporium 121 side, engaging tooth 122 was arranged on full week.
The approximate straight line Y along the axis of rotation O by second gear 41 of bearing surface 122a forms, and plane of inclination 122b is with along with away from extending towards the clockwise direction around rotating center O away from the state of perisporium 121 as the teeth groove 122c of cardinal extremity.
As mentioned above, in mode of execution, coating lubricating grease gets final product on the engaging pawl 113 of ratchet component 110 at least, but comparatively it is desirable to, and also is coated with lubricating grease on the engaging tooth 122 that slides for engaging pawl 113.This be because: not only further prevent to engage the wearing and tearing of pawl 113 and engaging tooth 122, and impact and noise when further slowing down engaging pawl 113 and falling into teeth groove 122c.
Fig. 7 (a) is a plan view of observing second small gear 42 from cover plate 5 sides, and Fig. 7 (b) is the A-A sectional view of Fig. 7 (a).
Second small gear 42 comprises: discoid base portion 141, and this base portion 141 is formed with the 42a of tooth portion in periphery; Shaft sleeve part 142, this shaft sleeve part 142 is from base portion 141 axially stretching out towards rotating center O; Embedding part 143, this embedding part 143 is embedded in ratchet component 110; And support 144, towards stretching out with shaft sleeve part 142 opposition sides, these members are integrally formed from base portion 141 for this support 144.
Second small gear 42 is provided with the axial penetration hole 145 along rotating center O, and as shown in Figure 2, in housing 2, second small gear 42 is inserted logical supporting axle S3 in penetration hole 145 rotatably mounted.
As shown in Figure 7, embedding part 143 forms by the upper end side of the shaft sleeve part 142 of drum being used with respect to rotating center O symmetry and two parallel faces excisions, thereby has planar surface portion 143a parallel to each other.
Embedding part 143 has the sectional shape with the embedding hole 115 (with reference to Fig. 5) of ratchet component 110 coupling, and as shown in Figure 2, second small gear 42 is by chimeric with embedding part 143 and embedding hole 115, thereby can link rotatably with ratchet component 110 one.
The axial height h3 of embedding part 143 sets the roughly the same height of thickness W1 (with reference to Fig. 5 (b)) with the main part 111 of ratchet component 110 for, under the state that is assembled with second compound gear, with shaft sleeve part 142 axially on upper-end surface 142a the main part 111 of ratchet component 110 is supported.
As shown in Figure 2, under the state that is assembled with second compound gear 40, surrounding wall 124, the second gears 41 that are arranged with second gear 41 on the shaft sleeve part 142 can be bearing on the shaft sleeve part 142 rotatably around rotating center O.
The upper-end surface 142a that the axial height h4 of shaft sleeve part 142 sets shaft sleeve part 142 for is the outstanding height towards the top a little from the upper end 124a of the surrounding wall 124 of second gear 41.
At this, surrounding wall 124 rotating center O axially on have specific length, since with shaft sleeve part 142 axially on almost Zone Full contact, therefore suppress second gear 41 and second small gear 42 spool the rocking of second gear 41 when rotating center O rotates by surrounding wall 124.
Fig. 8 (a) is the figure from the cap 150 of the beneath cover plate 5 of partition wall 6 sides, Fig. 8 (b) be Fig. 8 (a) the A-A sectional view, be the figure that represents second gear 41 and second small gear 42 with double dot dash line.
Shown in Fig. 8 (b), cover plate 5 is provided with cap 150, and this cap 150 is sealed the opening of cover plate 5 sides of the containing room 120 of second gear 41.
Shown in Fig. 3 and Fig. 8 (a), cap 150 is for there being the round-ended cylinder shape, and makes bottom wall portion 150a outstanding towards lid 4 (with reference to Fig. 1) side top, thereby integrally formed with cover plate 5.
Shown in Fig. 8 (b), the front end 152a of partition wall 6 (with reference to Fig. 1) side of chimeric wall portion 152 is more outstanding by the below of partition wall 6 sides towards the face 5a than partition wall 6 sides of cover plate 5, under the state that is assembled with second compound gear 40, have can with the height of the upper surface 41b butt of second gear 41.
Under the state that is assembled with second compound gear 40, the perisporium of second gear 41 embeds in the chimeric wall portion 152 from the below of partition wall 6 sides, thereby seal the opening of cap 150 sides of containing room 120 with cap 150, between the cover plate 5 and second gear 41, be formed with the almost space S of sealing.
In the mode of execution, in this space S of having sealed, be provided with the ratchet mechanism 100 (with reference to Fig. 3) that the engaging tooth 122 by interior week of the engaging pawl 113 of ratchet component 110 and perisporium 121 constitutes, thus can be owing to engaging pawl 113 disperses to the outside of airtight space S the lubricating grease of coating on engaging pawl 113 and the engaging tooth 122 with respect to the engaging of engaging tooth 122, impact that disengaging causes.
In the central authorities of the bottom wall portion 150a of cap 150, outstanding to the bearing portion 151 that the upper end of supporting axle S3 is supported towards the top of lid 4 sides, thus be wholely set with cap 150.
And, shown in Fig. 8 (a), on the face of partition wall 6 (with reference to Fig. 1) side of bottom wall portion 150a, be that the groove 153 of ring-type is located at from chimeric wall portion 152 and is left towards radially inner side on the position of predetermined distance from end on observation, groove 153 formed with same widths W2 on full week.
The width W 2 of above-mentioned groove 153 is with the width dimensions bigger than the width W of the arm 112 of ratchet component 110 (W2>W) form, under the state that is assembled with second compound gear 40, as among the figure with shown in the double dot dash line, the almost Zone Full outside the engaging pawl 113 of the cardinal extremity 112b of the arm 112 of removing ratchet component 110 and front end 112a side is configured on end on observation and groove 153 position overlapped.
In addition, in mode of execution, because the ratchet component 110 and second small gear 42 also are arranged to have in the axial direction a little loosening, even therefore ratchet component 110 with second gear 41 towards cap 150 side shiftings, for the major part of the arm 112 that makes ratchet component 110 does not contact with the face 150b relative with second gear 41 of bottom wall portion 150a, thereby be provided with groove 153.
This be because: if arm 112 in very large range contacts with the bottom wall portion 150a of cap 150, then ratchet component 110 is when the resiliently deformable of direction shown in the symbol is done rotation relatively with respect to second gear 41 in figure while the front end 112a side that makes arm 112, because of the friction between arm 112 and the bottom wall portion 150a, thus the resiliently deformable that can hinder arm 112.
In the ratchet mechanism 100 of described structure, as shown in Figure 4, observe from cover plate 5 sides, if to second small gear 42 input make ratchet component 110 with respect to second gear 41 around right handed rotation torque, then the rotation torque of being imported make arm 112 on one side front end 112a side towards main part 111 (rotating center O) thus the side resiliently deformable makes engaging that pawl 113 slides on the 122b of the plane of inclination of engaging tooth 122, on one side than when making the ratchet component 110 needed moments of torsion of rotation (stress) big, ratchet component 110 is rotated around clockwise direction.
In addition, observe from cover plate 5 sides, if 42 inputs make ratchet component 110 with respect to the rotation torque of second gear 41 around the counter clockwise direction rotation to second small gear, then the engaging pawl 113 of ratchet component 110 engages with the teeth groove 122c of engaging tooth 122, thereby makes the ratchet component 110 and the second gear one around rotation counterclockwise.
In mode of execution, as shown in Figure 2, since the sealing of ratchet component 110 between the perisporium 121 of the cap 150 that is formed at cover plate 5 and second gear 41 space S in, even therefore while 113 engagings of engaging pawl, disengaging being rotated, also can making the lubricating grease of coating on engaging pawl 113 and the engaging tooth 122 can not disperse to the outside because of engaging pawl 113 engages the impact that produces with the teeth groove 122c of engaging tooth 122.
At this, first solid of rotation during second small gear 42 in the mode of execution is equivalent to invent, second solid of rotation during second gear 41 in the mode of execution is equivalent to invent, the rotating member during the ratchet component 110 in the mode of execution is equivalent to invent.
And, the bearing during the bearing portion 151 in the mode of execution is equivalent to invent, the portion of running through during the shaft sleeve part 142 in the mode of execution is equivalent to invent.
As mentioned above, in mode of execution, as Fig. 2~shown in Figure 4, with second gear 41 of second small gear, 42 coaxial settings on be provided with predetermined distance and surround perisporium 121 with the periphery of the ratchet component 110 of second small gear, 42 one rotation, and be formed with the containing room that bottom tube-like is arranged 120 of accommodating ratchet component 110 in the inboard of this perisporium 121, utilization is by from the arm 112 of ratchet component 110 towards radially-protruding engaging pawl 113 be located at interior week of perisporium 121, constitute for make progress in the footpath of ratchet component 110 engaging tooth 122 of elasticity engaging of engaging pawl 113, and be coated with the ratchet mechanism 100 of the lubricating grease of toughness at least one side in engaging pawl 113 and the engaging tooth 122, make second small gear 42 and second gear 41 make engaging pawl 113 on one side with respect to engaging tooth 122 engagings, break away from one side and rotate relatively around common supporting axle S3, and the cap 150 of the opening seal containing room 120 is set, thereby make of the engaging of engaging pawl 113 with respect to engaging tooth 122, disengaging at the base closed that forms by the opening of the containing room 120 of sealing bottom tube-like with cap 150 space S in carry out.
By this, even owing to,, therefore lubricating grease is retained in the space S because space S is the space of almost sealing because of engaging pawl 113 disperses lubricating grease with the impact that produces that engages of engaging tooth 122.
Therefore, even long-time the use can not make the amount of the lubricating grease that the contact segment that engages pawl 113 and engaging tooth 122 at least is lubricated reduce in a large number as the existing compound gear that comprises clutch mechanism yet, the effect of lubricating grease is continued.
And as shown in Figure 8, cap 150 is the integrally formed structure of the bearing portion of being supported with shared supporting axle S3 to second small gear 42 and second gear 41 151.
By this, owing in motor drive unit 1, be used for the existing member that supporting axle S3 is supported is constituted cap 150, so need not to be provided as in addition the member of the lid that is used to prevent that lubricating grease from dispersing.Therefore, can not only prevent that component number from increasing, can also prevent to follow the rising of the fabricating cost that component number increases.
In addition, because cap 150 is integrally formed with bearing portion 151, can be that benchmark comes the positional accuracy highland that cap 150 is set therefore, and improve the positional accuracy of engaging tooth 122 and cap 150 with bearing portion 151.
And, if split constitutes cap 150, then, need carry out cap 150 is assembled in the operation of the perisporium 121 of second gear 41 for the opening of sealing containing room 120 with cap 150 forms space S, operating cost is risen.If cap 150 is integrally formed with bearing portion 151, then owing to need not above-mentioned assembling procedure, specific energy reduction operating cost mutually when therefore constituting with split.
In addition, as shown in Figure 8, on cap 150, the chimeric wall portion 152 of the ring-type on the perisporium 121 that is embedded in second gear 41 on full week is axially side-prominent and form towards second gear 41 along supporting axle S3's, and the front end 152a of chimeric wall portion 152 is near the structure that extends to the upper surface 41b of second gear 41.
Generally speaking, for make engaging pawl 113 and engaging tooth 122 have supporting axle S3 axially on loosening, second gear 41 is arranged to and can be moved in a little scope in the axial direction.
If chimeric wall portion 152 was nested on the full week of perisporium 121, even then second gear 41 moves towards the direction away from cap 150, upwards observe from the footpath of supporting axle S3, owing to sealing the space S and outside slit that containing room 120 forms not producing to be communicated with between perisporium 121 and the chimeric wall portion 152, the lubricating grease that disperses because of the engaging pawl 113 and the impact that engages generation of engaging tooth 122 is retained in the space S reliably with cap 150.
By this, can prevent the leakage of lubricating grease preferably from space S, even long-time the use, the amount of the lubricating grease that the contact segment to engaging pawl 113 and engaging tooth 122 is lubricated is reduced in a large number, the effect of lubricating grease is continued.
And, shown in Fig. 8 (b), the area inside (relative face 150b) that in the face relative, is surrounded by chimeric wall portion 152 with second gear 41 for than the zone (face 5a) in the outside more supporting axle S3 axially on away from the structure of the direction biasing of second gear 41.
By this, install in cap 150 lateral deviations, therefore can make thickness on second gear 41 axial reduce the amount of being setovered owing to sealing the space S that containing room 120 forms with cap 150.
In addition, as shown in Figure 2, second gear 41 is with respect to the structure of gravitational direction towards the upside configuration with the opening of containing room 120.
By this, even because the impact that causes because of the engaging of engaging pawl 113 and engaging tooth 122 (with reference to Fig. 4) makes the lubricating grease court at least one side who coats in engaging pawl 113 and the engaging tooth 122 disperse with respect to cap 150 sides that gravitational direction is positioned at upside, the lubricating grease that has dispersed also can be because of gravity be back to the containing room 120 that is positioned at downside with respect to gravitational direction, thereby the contact area of engaging pawl 113 and engaging tooth 122 etc. is lubricated.
In addition, for example because of around environment be high temperature etc. makes that the viscosity of lubricating grease reduces, flowability uprises, and is cup-shaped because the cross sectional view of the containing room 120 of round-ended cylinder shape is arranged, can prevent comparatively ideally that therefore the lubricating grease that flowability has uprised from leaking to the outside.
And as shown in Figure 5, ratchet component 110 comprises: main part 111, thus this main part 111 rotates with 42 coaxial settings of second small gear and second small gear, 42 one; And arm 112, this arm 112 stretches out and has the front end 112a side displacement diametrically of engaging pawl 112 from the outer circumferential face 111a of main part 111, as shown in Figure 8, on the face relative of cap 150 with second gear 41, end on observation from supporting axle S3, the groove 153 of rotating center O that surrounds ratchet component 110 with predetermined distance is with the ring-type setting, during from the end on observation of supporting axle S3, the 112a side of front end at least of arm 112 and groove 153 position overlapped are extended along the outer circumferential face 111a of main part 111.
If constitute as mentioned above, even then be provided in supporting axle S3 axially on a little loosening ratchet component 110 is arranged towards cap 150 side shiftings, because not contacting of arm 112, so can not hinder the displacement of arm 112 towards main part 111 sides with the face 150b relative of cap 150 with second gear 41 from the overlapping part of the end on observation of supporting axle S3 and groove 153.In addition, not need for do not hinder arm 112 guarantee towards the displacement of main part 111 sides very big space S axially on thickness.
In addition, as shown in Figure 2, supporting axle S3 axially on, second gear 41 is between the cap 150 and second small gear 42, second small gear 42 has shaft sleeve part 142, this shaft sleeve part 142 runs through second gear 41 in the axial direction and forward end is positioned at containing room 120, and the embedding part 143 with the front end of shaft sleeve part 142 in the space S that ratchet component 110 forms sealing containing room 120 with cap 150 links, thereby becomes the structure that can be provided with rotatably with second small gear, 42 one.
By this, supporting axle S3 axially on, compare with the situation between second gear 41 with ratchet component 110 being located at second small gear 42, owing to can make second small gear 42 and second gear 41, therefore can reduce the thickness on second compound gear 40 axial near being provided with.
In addition, owing to seal the opening of containing room 120 as the cap 150 of the member of fixed side with relative second gear 41, therefore can seal containing room 120 and the space S that forms is made the space of almost having sealed with cap 150, thereby can prevent the leakage of lubricating grease even more ideally towards the outside of space S.
In addition, in mode of execution, illustration be provided with the situation of the containing room 120 of round-ended cylinder shape with second gear 41 and relative face cap 150, but containing room 120 also can be located on the face relative with second small gear 42.
In this case, the diameter of the 42a of tooth portion of second small gear 42 is bigger than the opening diameter of containing room 120, between second gear 41 and second small gear 42, because the lid member of circular plate shape that can diameter is bigger than the opening diameter of containing room 120 and second small gear 42 or second gear, 41 one are provided with etc. rotatably, therefore by sealing the opening of containing room 120, can prevent dispersing of lubricating grease.
In mode of execution, illustration observe from cover plate 5 sides, when input makes ratchet component 110 with respect to second gear during around right handed rotation torque, ratchet component 110 (second small gear 42) and the 41 relative rotations of second gear, and when importing the rotation torque that rotates around counter clockwise direction, the situation of the ratchet mechanism 100 that ratchet component 110 (second small gear 42) and the rotation of second gear, 41 one are such.
But, if engaging pawl 113 with respect to the engaging of engaging tooth 122, break away from the space S of between cap 150 and perisporium 121, sealing and carry out, also can be to make ratchet component 110 with respect to second gear during around right handed rotation torque when input, ratchet component 110 (second small gear 42) and the rotation of second gear, 41 one, when input during around the rotation torque of rotation counterclockwise, then ratchet component 110 (second small gear 42) is relative with second gear 41 rotates such ratchet component.
And, also can be no matter to import around clockwise direction with around the situation of anticlockwise any one rotation torque, all the shape adjustments with engaging tooth becomes to make ratchet component 110 (second small gear 42) and second gear, 41 counterrotating ratchet mechanisms.
In mode of execution, with coating lubricating grease on the pawl of engaging at least 113 of ratchet component 110 is that example is illustrated, but also can be for the engaging tooth 122 of engaging pawl 113 elasticity engaging, comparatively it is desirable to be coated with lubricating grease on the whole surface at engaging tooth 122, or on engaging tooth 122 and engaging pawl 113, all be coated with lubricating grease.
According to like this, not only prevent to engage the wearing and tearing of pawl 113 and engaging tooth 122, and impact and noise when slowing down engaging pawl 113 and falling into teeth groove 122c.
And, thereby also can be configured in the containing room 120 of second gear 41 repack with grease ratchet component 110 is submerged in the lubricating grease.
In this case, when second small gear 42 is done rotation relatively with respect to second gear 41, because ratchet component 110 is rotated while stirring lubricating grease, so the high viscosity of lubricating grease can hinder the rotation of ratchet component 110, thereby all the time the rotation of ratchet component 110 applied braking force.
In mode of execution, illustration be separated bearing portion 151 supporting of wall 6 and cover plate 5 with two ends supporting axle S3 respectively ratchet component 110, second gear 41 and second small gear 42 are supported to rotatablely, and supporting axle S3 is the situation of stationary axle.But supporting axle S3 can link rotatably with second small gear, 42 one, thereby makes the two ends of supporting axle S3 be separated the rotatably mounted rotating shaft of wall 6 and bearing portion 151 respectively.
In mode of execution, illustration the area inside (relative face 150b) that surrounded by chimeric wall portion 152 in the face relative of cap 150 with second gear 41 than the zone (face 5a) in the outside more supporting axle S3 axially on away from the situation of the direction biasing of second gear 41, but relative face 150b and face 5a are not setovered and be formed on the identical faces.
