This speed reducer 310 is so-called swing internally meshed type planet-gear speed reducers, from shell 317 outputting powers.Its result is rotated by shell 317 and bolt 380 incorporate tool magazine bodies 171.
As in the above-mentioned automatic tool changer, follow processing and disperse break flour or freezing mixture (cutting oil), these break flours or freezing mixture also might invade in the speed reducer 300.
Below, the structure of the related speed reducer 300 of an example of embodiments of the present invention is described.
Fig. 1 illustrates the sectional arrangement drawing of the related speed reducer 300 of embodiments of the present invention 1.In addition, Fig. 2 be depicted as prevent that speed reducer from coming off and the plectane that is provided with 319 with the 1st anchor plate 314 axially on opposed enlarged view.
The brief configuration of speed reducer 300 at first, is described.
In addition, reference character 302 illustrates the recess of the motor reel (all omitting diagram) that inserts motor (driving source).
The motor reel of the output shaft of motor links with the relay axis 303 that is arranged on fixing part 308.Front end at relay axis 303 cuts and the small gear 304 and bevel gear (umbrella gear) 307 engagements of formation.This bevel gear 307 links an end of the input shaft 311 that is fixed on speed reducer 310 by bolt 305.In addition, constitute the axle center O2 of small gear 304 and the axle center O1 of bevel gear 307 and form predetermined angle A.
The structure of speed reducer 310 becomes as follows.
The related speed reducer 310 of present embodiment possess the internal gear (annular element) 313 that is located at rotational shell (shell) 317, in be connected on internal gear 313 external gear (inner part) 312, be configured in the axial both sides of external gear 312 the 1st, the 2nd anchor plate 314,315, link sold inside the country (the binding parts) 323 of the 1st, the 2nd anchor plate 314,315.
" rotational shell 317 " of the present invention is defined as, and not only comprises rotational shell 317, as the plectane in the enforcement mode 319, also comprises the parts that are fixed on rotational shell 317 by one.
Be formed with three eccentric bodies 326 (326A, 326B, 326C) at input shaft 311.Periphery at this eccentric body 326 is assembled with aforementioned external teeth wheel 312 by roller 334 (334A, 334B, 334C).
In addition, the eccentric phase place of each eccentric body 326 is offset 120 degree respectively, and the eccentric phase difference of external gear 312 is 120 degree.
On the one hand, internal gear 313 is installed on export trade (roller) 340 formations in the interior week of rotational shell 317 freely by rotation.
In addition, roller 324 in the periphery of being sold inside the country 323 is equipped with as the promotion parts that slide.
Then, illustrate about speed reducer 310 prevent come off and the anti-locking mechanism of inflow of break flour etc.
In the present embodiment, become rotational shell 317 (more specifically being attached at the plectane 319 of rotational shell 317) and possess gap 350 and mutual opposed structure with the 1st anchor plate 314 by bolt 318.
At first, plectane 319 and the 1st anchor plate 314 mutual opposed structures are described.
In the rotational shell 317, the side end in the axial restraint portion 308 of this rotational shell 317 is provided with plectane 319 by bolt 318.Plectane 319 possesses the protuberance 319J that more protrudes in the radial direction inboard than rotation shell 317.And, be installed in the cover 320 of an opposite side with fixing part of this speed reducer 300, be fixed on rotational shell 317 by bolt 321.The rupture stress of the bolt 318 that the plectane 319 that is fixed on this rotational shell 317 is fixed is set the rupture stress that carries out the bolt 321 of stop greater than the cover 320 to the opposite side with fixing part of speed reducer 300 for.This is because when sold inside the country 323 fractures, the weight of the 2nd anchor plate 315 that the rotational shell 317 that bolt 318 is supported and the weight of the 2nd anchor plate are supported greater than bolt 321.
On the end of the 1st anchor plate 314 1 sides of fixing part 308, be formed with stepped part 314B, and the interior perimembranous 319C of plectane 319 regards to this stepped part 314B.Plectane 319 with the face P1 that intersects of axle O1 of rotational shell 317 on have the opposite side of court with driving source the 1st 319A.
Accordingly, the 1st anchor plate 314 possesses near the end periphery of its axial driving source one side towards driving source one side, and with the 1st 319A with opposed the 2nd 314A of non-contact.
Because the outside diameter d 1 of the 1st anchor plate 314 that possesses the 2nd 314A is greater than the inside diameter D 1 of the plectane 319 that possesses the 1st 319A, therefore the 1st 319A and the 2nd 314A are overlapping when axial direction is observed.
In addition, possesses gap 350 with the integrally formed plectane 319 of rotational shell 317 with fixing part 308 and the 1st anchor plate 314.Gap 350 forms コ font section for the end periphery (in order to obtain the labyrinth effect) around plectane 319 in the present embodiment.The width X in this gap 350 is by the internal diameter of the plectane 319 of the size of the kind of considering freezing mixture and break flour and axial thickness and determine.
Between this rotational shell 317 and plectane 319, the packing ring 327 that has a gap at circumferencial direction is engaged and is configured on the bolt 318.
In addition, dispose bearing 322A between the 1st anchor plate 314 and the input shaft 311, between the 2nd anchor plate 315 and input shaft 311, dispose bearing 322C, between the 1st anchor plate 314 and rotational shell 317, dispose bearing 322B, between the 2nd anchor plate 315 and rotational shell 317, dispose bearing 322D.
In the present embodiment, the 1st anchor plate 314 of driving source one side is fixed on the fixing part 308.And, because linking by integrally formed sold inside the country 323, the 1st anchor plate 314 is fixed with the 2nd anchor plate 315, therefore be sold inside the country the 323 or the 2nd anchor plate 315 and also link and be fixed on the fixing part 308.
The effect of speed reducer 300 then, is described.
To not shown motor (driving source) input rotation indication, then motor reel only rotates the amount (angle) that is instructed to.The rotation of this motor reel is passed to small gear 304 by relay axis 303, and then, be passed to and this small gear 304 meshed bevel gears 307.Because this bevel gear 307 is bonded on the input shaft 311 that is fixed on speed reducer 310, so just rotation of input shaft 311.
If input shaft 311 rotations then are formed on the just rotation of eccentric body 326 of input shaft 311.Its result, the external gear 312 that is loaded into the periphery of eccentric body 326 by roller 334 is swung rotation.In the present embodiment, sold inside the country 323 connect external gears 312, and this sold inside the country 323 is fixed on the fixing part 308 by the 1st anchor plate 314, so the rotation of this external gear 312 is restricted.Thus, the internal gear 313 with external gear 312 engagements carries out displacement relatively (rotation) with the reduction speed ratio external gear wheel 312 that is equivalent to (internal gear 313 is poor with the number of teeth of external gear 312)/(number of teeth of internal gear 313).The rotation of this internal gear 313 is derived from the rotational shell 317 of integrally formed internal gear 313.
In addition, because plectane 319 not to be all being set up with the 1st anchor plate 314 or with the 1st anchor plate 314 incorporate fixing part 308 state of contact, the rotation of the speed reducer 310 during therefore to common operation does not give any influence.On the one hand, the 2nd anchor plate 315 firmly links with sold inside the country 323.Thereby when moving usually, the 2nd anchor plate 315 or rotational shell 317 can not come off from fixing part 308 1 sides that comprise the 1st anchor plate 314.
Yet when any accidents such as generation collision, in the speed reducer 310 of this structure, look firm sold inside the country 323 or bolt 316 rupture sometimes.
Therefore, in the structure of this fracture without any misgivings, if sold inside the country 323 or bolt 316 fractures, the 2nd anchor plate 315 or rotational shell 317 just lose its supporting basis so, and might take place together to come off with rotational shell 317.
Yet, in the present embodiment, the 2nd 314A of the end face of the 1st 319A of an axial opposite side of plectane 319 and fixing part 308 1 sides of the 1st anchor plate 314 with fixing part, because it is overlapped when axle looks up, make sold inside the country 323 in speed reducer 310 or bolt 316 destroyed even therefore apply intense impact, the 1st 319A also can be stuck on the 2nd 314A, thereby prevent that structurally rotational shell 317 from coming off etc., the therefore Security that can improve speed reducer 300.In addition, because cover 320 is arranged to hide the 2nd anchor plate 315, therefore also can prevent 2 losses that cause by falling of the 2nd anchor plate 315.
And, form the 2nd 314A for the ease of end at the 1st anchor plate 314 that originally separates with fixing part 308, owing to do not need engaging of convex and convex, therefore although the shape of the 1st, the 2nd 319A, 314A has overlappingly on radial direction, the inconvenience that flexibility in the assembling of speed reducer 300 or simplification reduce also can not take place.
In addition,, consider the size of break flour etc., become the gap 350 that possesses width X and mutual opposed structure by rotational shell 317 and plectane 319 and fixing part 308 or the 1st anchor plate 314 that bolt 318 links.Thus, plectane 319 constitutes complicated passage with fixing part 308 or the 1st anchor plate 314, and the pressure loss that flow into fluid wherein increases, and the influx minimizing, thereby can bring into play the effect (labyrinth effect) of sealing.Its result can prevent the break flour of processing object thing of speed reducer 300 peripheries or the inflow of freezing mixture.Thus, can prevent from also to be positioned at the damage etc. of the oil sealing 341 of speed reducer 310 inboards than plectane 319.
And packing ring 327 is stuck and is configured on the bolt 318 between rotational shell 317 and plectane 319, thus the gap of guaranteeing circumferencial direction.Thus, even for example freezing mixture enters in the speed reducer 310 by stepped part 314B, also make this freezing mixture in speed reducer 310 because gravity and moving towards vertical lower, and be discharged to speed reducer 310 outsides from the gap of the circumferencial direction guaranteed by this packing ring 327.
The gap of this circumferencial direction is adjusted according to the thickness T of packing ring 327.This gap wide for break flour does not enter the width that freezing mixture is easy to discharge considered the size of the viscosity of freezing mixture and break flour and determined.
As above, need not be with structure complicated, part even apply strong impact in the speed reducer 310 is destroyed, also can structurally prevent rotational shell 317 or comprise that the major part of the speed reducer 310 of this rotational shell 317 comes off, prevent that simultaneously powder or liquid from flowing into inside, and can improve the Security of speed reducer 300.
That is, just can realize preventing come off two kinds of functions with the inflow that prevents freezing mixture etc. of rotational shell 317 grades with a kind of structure.
In addition, in the above-described embodiment, though in order to make the 1st 319A and the 2nd 314A opposed, be provided with stepped part 314B (Fig. 2) as the space that plectane 319 is faced, but also the periphery of fixing part 308 can be designed to less than all D1a in the plectane, and need not stepped part be set thus and only make the 1st 319a1 and the 2nd 314a2 opposed (Fig. 4 (a)).That is, can be only in the 1st anchor plate 314 1 sides or only step (only having formed step in fixing part 308b one side in the illustrated example) is set in fixing part 308 1 sides, and the 2nd 308b2 is set here, with the 1st 319b1 opposed mutually (Fig. 4 (b)).
And, also can will constitute recess and constitute the protuberance that enters this recess at rotational shell 317c or 317d one side at the 1st anchor plate 314c or fixing part 308d side, and by making both opposed the 1st 317c1,317d1, the 2nd 314c2,308d2 (Fig. 4 (c), (d)) of forming.And, also can make the protuberance of the 1st anchor plate 314e or fixing part 308f and rotational shell 317e, 317f opposed, thereby form the 1st 319e1,319f1, the 2nd 314e2,308f2 (Fig. 4 (e), (f)).In addition, also can be by only recess being set in the 1st anchor plate 314g one side or fixing part 308h one side, and the protuberance that will be fastened on this recess is arranged on the rotational shell 317 and forms the 1st 319g1,319h1, the 2nd 314g2,308h2 (Fig. 4 (g), (h)).So, the 1st the formation method with the 2nd is not limited to above-mentioned example.Particularly, when by combination end difference or protuberance, when forming the 1st, the 2nd with recess, protuberance, recess may not be at full Zhou Lianxu, for example also can be by form the 1st or the 2nd 's structure towards the inboard protuberance that forms of radial direction from the four directions.
Under the above-mentioned situation,, make it more opposed by fixing part 308 1 sides (an opposite side) with driving source than oil sealing 341 for the damage of the oil sealing 341 that prevents to cause by break flour.The gap 350 that more preferably has the width X that can obtain the labyrinth effect is also opposed mutually.
In addition, move (part that enters flows out) smoothly, used packing ring 327 as the parts of guaranteeing the circumferencial direction gap in order to make the freezing mixture that enters stepped part 314B, but also passable without packing ring 327 with custom-designed parts.And, also can not dispose packing ring 327 grades and guarantee the parts in gap.
In addition, if when sold inside the country 323 rupture, can support the parts of speed reducer integral body 310, then also the rupture stress of two bolts 318,321 can be designed to identical size.Yet according to the relation of above-mentioned functions, when the rupture stress of bolt 321 during greater than bolt 318, promptly opposite with the magnitude relationship of the rupture stress of the bolt 318,321 of present embodiment is not preferred.
The present invention for example also goes for the speed reducer 400 shown in Fig. 3.
In this speed reducer 400, the power of not shown motor (driving source), small gear 404 and bevel gear (umbrella gear) 407 engagements by forming in the cutting of relay axis 403 front ends are passed to input shaft 411.On input shaft 411, be formed with driving pinion 430.And driving pinion 430 and three distribution gears 431 (only illustrating among Fig. 3) mesh simultaneously.This distribution gear 431 and forming as one of three eccentric axons 432 (only illustrating among Fig. 3).
Three eccentric axons 432 possess separately axially on the same position from the axle center with two groups of cophasing off-centre totally 6 eccentric bodies 426 (illustrated embodiment, only illustrating wherein two 426A, 426B).On this eccentric body 426, external gear 412 (412A, 412B) arranged by roller 434 (only illustrating 434A, 434B) is chimeric.
Dispose the 1st, the 2nd anchor plate 414,415 in the axial both sides of external gear 412 (driving source one side and an opposite side), and support rotational shell 417 freely by the relative rotation of bearing 422B, 422D with driving source.The 2nd anchor plate 415 utilizes bolt 416 and links fixing by wheel support body (binding parts) the 423 and the 1st anchor plate 414.By these structures, under the confined state of the autobiography of external gear 412, with the integrally formed internal gear 413 of rotational shell 417 on swing and in mesh.
In the present embodiment, when wheel support body 423 ruptures in order waiting in the generation collision, the structure identical can be to adopt, equally, coming off of rotational shell 417 and the 2nd anchor plate 415 can be to prevent with top mode of execution.Because this structure itself is identical with top mode of execution, thus possess add on the parts of identical or similar function and top mode of execution after two identical symbols, and omitted repeat specification.
In addition, the kind of applicable speed reducer of the present invention does not limit.Except swing internally meshed type speed reducer, for example, also go for having this sun gear, outer gearing in the planetary pinion (inner part) of this sun gear, this planetary pinion in the simple planetary type speed reducer of outer housing rotary type of internal gear (annular element), binding parts that rotation keeps planetary rollers freely of engagement.
Except simple epicyclic reduction gear of planetary type device, equally also go for having with shell form incorporate ring roller (annular element), in be connected to the ring roller planetary rollers (inner part), possess with the section of the concave circular arc shape of the roughly the same curvature of the outer circumferential face of holding member (planet) roller and rotate from outer circumferential side on the outer housing rotary type Friction speed-reducing device of the binding parts that keep planetary rollers freely, and can obtain identical action effect.
And in the above-described embodiment, in order to realize preventing to come off and two kinds of effects that prevent to flow into, though have the gap that can obtain the labyrinth effect and make it opposed mutually, as long as realize preventing the effect that comes off, the size in gap just is out of question so.
