Detailed description of the invention
Below, with reference to the accompanying drawings an example of embodiments of the present invention is described in detail.
Fig. 1 represents the feedway involved by an example of embodiments of the present invention and local comprises and puts birds-eye view heavy in section, and Fig. 2 is the front view of above-mentioned feedway, and Fig. 3 is the main portion amplification sectional view of Fig. 1.
This feedway 12 possesses the conveying mechanism 16 with axle drive shaft 14 and the gear motor 18 driving this axle drive shaft 14.Axle drive shaft 14 is fixed with driving wheel 22 by key 20.Although not shown, the right side by the paper of Fig. 1 and Fig. 2 is provided with flower wheel, between this driving wheel 22 and flower wheel, be wound with belt conveyor 24 annularly.
In addition, as shown in Figure 2, this transported substance P1, P2 ... be placed on belt conveyor 24 and be transferred.Also as described by Fig. 2, transported substance P1, P2 ... may not be configured to be placed in " directly over (on the axle namely as character express C1) " of axle drive shaft 14, even if wrapped around belt conveyor 24 as on present embodiment axle drive shaft 14, transported substance P1, P2 ... be placed in the situation on this belt conveyor 24, be also contained in the concept of " transported substance passes through on the driving shaft " in the present invention.Axle drive shaft 14 is fixed on the parts 30A of fixed mount by fixed mount (fixed parts) 30(that bearing 25,26 is rotatably freely supported on conveying mechanism 16).
Gear motor 18 links (aftermentioned) by the fixed mount 30 of torque arm connect mechanism 32 and conveying mechanism 16.
Below the structure of gear motor 18 is described.
Gear motor 18 is that motor 34 and reductor 36 integration form.
The front end of the motor drive shaft 34A of motor 34 is formed with hypoid pinion 38.Hypoid pinion 38 engages with skew bevel gear 40.Skew bevel gear 40 is fixed on tween drive shaft 42 by key 44.Tween drive shaft 42 is rotatably freely supported on the housing body 50A of the housing 50 of (gear motor 18) reductor 36 by pair of bearings 46,48.In addition, housing 50 by eliminating mark in through bolt 51(accompanying drawing, and only illustrates through bolt hole to substitute with same-sign 51 in fig. 2) link housing body 50A and case cover 50B.
Tween drive shaft 42 is fixed with spur gear 54 by key 52.Spur gear 54 engages with output gear 56.Output gear 56 is fixed on output shaft 58 by key 60.
Output shaft 58 is for having the hollow output shaft of hollow bulb 58A in this embodiment.The inner circumferential of output shaft 58 is formed with the keyway 58B throughout this output shaft 58 total length.On the other hand, axle drive shaft 14 side is also formed with (to stagger shown in phase place) keyway 14A.Output shaft 58 is by being can transmitting torque with axle drive shaft 14 with coaxial manner link across the key 57 between this keyway 58B and keyway 14A.Output shaft 58 is rotatably freely supported on main body 50A and the cover 50B of the housing 50(of reductor 36 by pair of bearings 62,64: the parts of block bearing).
In this embodiment, the opening bearing (not being the so-called sealed bearings with sealing element) without sealing element is adopted to be used as bearing 62,64.The outer ring 62A of load-side bearing 62 abuts with the stage portion 50A1 being formed at housing body 50A.Further, the inner ring 62B of load-side bearing 62 abuts with described output gear 56, and output gear 56 abuts with the stage portion 58C being formed at output shaft 58.
On the other hand, the outer ring 64A of load reverse side bearing 64 abuts with the stage portion 50B1 being arranged at case cover 50B, and inner ring 64B abuts with the projection 58D being arranged at output shaft 58.
Its one end of output shaft 58 abuts with the stage portion 14D of axle drive shaft 14.Thus, by bolt 70 is screwed into across the lid 66 abutted with the end 58E of output shaft 58 the screw 14S being formed at axle drive shaft 14, distance L1 between the end face 14C of axle drive shaft 14 and lid 66 is shortened, thus axle drive shaft 14 and output shaft 58 can be firmly fixed vertically.
As aforementioned, in this embodiment, gear motor 18 links by the fixed mount (fixed parts) 30 of torque arm connect mechanism 32 and conveying mechanism 16.
When the gear motor 18 of the axle drive shaft 14 for being installed on feedway 12 with coaxial manner, once direct rotation motor axle 34A, then (be not the axle drive shaft 14 of conveying mechanism 16 rotate but) whole gear motor 18 is rotated because of counteraction around axle drive shaft 14.To use torque arm connect mechanism 32 to prevent this phenomenon from linking for the purpose of the housing 50 of gear motor 18 and the fixed mount 30 of conveying mechanism 16.
In this embodiment, torque arm connect mechanism 32 by torque arm 72, for by this torque arm 72 jointly fastening/be fixed on the main body 50A of the housing 50(of the reductor 36 of gear motor 18) described through bolt (only illustrating through bolt hole) 51, form for torque arm 72 being fixed on the bolt 74 of the fixed mount 30 of conveying mechanism 16, nut 75 and pad 76.
Specifically, torque arm 72 as shown in FIG. 1 to 3 involved by this embodiment, with main look observation time be general triangular shape, with bend to during top view of bonding with the link surface 72A of aligning and gear motor 18 and and the link surface 72B of fixed mount 30 between distance L2.Thereby, it is possible to abut with the stationary plane 30B of the fixed mount 30 of conveying mechanism 16 and the stationary plane 50A2 both sides of housing body 50A.
From Fig. 1, Fig. 3 also clearly, in this embodiment, the link surface 72A of housing 50 side of torque arm 72 directly contacts with the stationary plane 50A2 of housing body 50A.Further, the link surface 72B of fixed mount 30 side of torque arm 72 directly contacts with the stationary plane 30B of the fixed mount 30 of conveying mechanism 16.Further, torque arm 72 is firmly fixed at housing 50 by through bolt 51, bolt 74, nut 75 and pad 76 and fixed mount 30(torque arm 72 is all fixed into fixed mount 30, torque arm 72 cannot moves axially relatively with housing 50).In other words, this gear motor 18 is by the housing 50 of the fixed mount of conveying mechanism 16 (fixed parts) 30 and gear motor 18 being fixed into the torque arm connect mechanism 32 that cannot move axially relatively and (in fact cannot movably vertically) be fixed on the fixed mount 30 of conveying mechanism 16.
As already described, in this kind of feedway 12, the connect mechanism of use torque arm 72 is the necessary constitutive requirements for the phenomenon preventing this gear motor 18 self from rotating, but as this link example, if the fixed mount 30 of conveying mechanism 16 and the housing 50 of gear motor 18 are not left no room (cannot infinitesimal deflection ground) firmly fix, then when axle drive shaft 14 movement vertically due to conveying mechanism 16 makes the output shaft 58 of reductor 36 move vertically, (housing 50 entirety due to gear motor 18 cannot be followed the movement of this output shaft 58 and move) has to by means of only the relative movement between housing 50 and output shaft 58 to absorb this infinitesimal deflection.Therefore, as above-mentioned link form, the link form as torque arm 72 is actually undesirable.About the link of torque arm 72, be preferably mounted to have a little vertically " play ", infinitesimal deflection can be carried out vertically to make the housing 50 of gear motor 18 relative to the fixed mount 30 of conveying mechanism 16.That is, even the torque arm connect mechanism 32 involved by this embodiment, actual when being linked by this torque arm connect mechanism 32, also preferred by nut 75 to stop under the state not being fastened to the end.
But the installation of torque arm connect mechanism 32, the field operation of having to become because of the position relationship of the fixed mount 30 with conveying mechanism 16, also will entrust in user side sometimes usually.Further, often occur in the middle of reality, even if maker installs, but in the inspection of user side afterwards, make the housing 50 of gear motor 18 cannot axially movably be linked to fixed mount 30 by torque arm 72 owing to being fastened to by nut 75 last.
The unfavorable conditions such as the checking according to inventors is learnt, the lubricant leakage of this kind of feedway 12, especially easily occur in this situation.From the words that other viewpoints are understood, the present invention can be called: result from the phenomenon that axial vibration between the housing 50 of gear motor 18 and output shaft 58 or relative movement are considered to must cause in the feedway likely used by this way, time by this way by use, have employed the invention of " oil sealing considering the structure of the distinctive situation of feedway " to not make the undesirable conditions such as lubricant leakage produce.
In this embodiment, the oil sealing 80,81 be configured between output shaft 58 and housing 50 has: be arranged at the axially outside of bearing 62,64 and single metal outside annulus 82 and be arranged at 2 the 1st main lips 86, the 2nd main lip 88 of neoprene of front end of the support outstanding to inner circumferential side of annulus 82 outside this 83,84.In addition, the oil sealing 81 of load-side is the identical parts of oil sealing 80 with load reverse side, and is mounted to only in the axial direction towards the opposite.
The oil sealing 80 being conceived to load reverse side is described, although this oil sealing 80 has 2 the 1st main lips 86, the 2nd main lip 88, metal outside annulus 82 is " 1 ", as the parts being called oil sealing 80, is 1 parts to beginning extremely eventually.
1st main lip 86, the 2nd main lip 88 of oil sealing 80 take on Main Function in the sealing function of this oil sealing 80.1st main lip 86, the 2nd main lip 88 both sides all relative to bearing 62,64 with equidirectional, is about to the form that oil seals well to the leakage reductor 36 in reductor 36 and arranges, and each has living shape.Further, the 1st main lip 86, the 2nd main lip 88 have the identical spring (force application mechanism) 90,91 for the 1st main lip 86, the 2nd main lip 88 being exerted a force to output shaft 58 respectively.The load reverse side that the load reverse side of the 1st main lip 86 is provided with the main lip 88 of the 1st secondary lip the 92,2nd is provided with the 2nd identical secondary lip 94 of lip 92 secondary with the 1st.Namely this oil sealing 80 contacts with output shaft 58 at 4 places altogether.
Then, the effect of this feedway 12 is described.
The motor drive shaft 34A mono-of motor 34 rotates, then the hypoid pinion 38 being formed at this motor drive shaft 34A front end also rotates integratedly.Its result, the skew bevel gear 40 engaged with hypoid pinion 38 rotates, and make spur gear 54 by tween drive shaft 42, output gear 56 rotates, the output shaft 58 being assembled in this output gear 56 rotates.In gear motor 18, housing body 50A due to the housing 50(of its reductor 36) fixed mount 30 of conveying mechanism 16 is linked to by torque arm 72, therefore once the output shaft 58 of reductor 36 rotates, then the axle drive shaft 14 of conveying mechanism 16 rotates integrally with this output shaft 58.Thus, the driving wheel 22 linked by key 20 and axle drive shaft 14 rotates, and is wound in the belt conveyor 24 also ring-type rotation of this driving wheel 22.Its result, by load on belt conveyor 24 transported substance P1, P2 ..., can on belt conveyor 24 (on axle drive shaft) conveying transported substance P1, P2 ...
Feedway 12 involved by this embodiment by this be used for conveying transported substance P1, P2 ..., therefore cannot prevent vibration because conveying mechanism 16 side occurs or mounting transported substance P1, P2 ... time impact especially make axle drive shaft 14 vibrate vertically in the running at the thrust load axially applied of axle drive shaft 14 etc. or the phenomenon of movement occurs.Further, the phenomenon being also difficult to prevent the movement of the axis of this axle drive shaft 14 to be directly delivered to the output shaft 58 of reductor 36 occurs.And, in this embodiment, though gear motor 18(undesirable as a result) be fixed on the fixed mount 30 of conveying mechanism 16 by torque arm connect mechanism 32, wherein the housing 50 of the fixed mount 30 of conveying mechanism 16 and the reductor 36 of this gear motor 18 is fixed into and cannot moves axially relatively by torque arm connect mechanism 32.Therefore, as long as have the vibration of axle drive shaft 14 or the infinitesimal deflection of axis to be input to output shaft 58(due to the housing 50 of reductor 36 be firmly fixed at fixed mount 30), then the vibration of this axle drive shaft 14 or the infinitesimal deflection of axis all show as Relative Vibration between output shaft 58 and the housing 50 of reductor 36 or relative infinitesimal deflection.Therefore, under oil sealing 80,81 is also exposed to very harsh state.
But, have employed the oil sealing 80 being arranged with 2 the 1st main lips 86, the 2nd main lip 88 in present embodiment.1st main lip 86, the 2nd main lip 88 both sides all relative to bearing 62,64 with equidirectional, namely with the morphologic arrangement sealed well to the leakage reductor 36 in reductor 36 oil, further, both sides are all abutted with the periphery of output shaft 58 by the reinforcing produced by spring 90.Therefore seal ability is extremely high.And the 1st main lip 86, the 2nd main lip 88 possess the 1st secondary lip 92, the 2nd secondary lip 94 respectively.Therefore, in the 1st main lip 86 and the 1st secondary lip 92, first standard seal is carried out.Further, if even if do not seal completely in the 1st main lip 86 and the 1st secondary lip 92, also again carry out standard seal, therefore its result in the 2nd main lip 88 and the 2nd secondary lip 94, very powerful sealing function can be maintained for a long time.In this, with the two-lip seal (only possessing the oil sealing being equivalent to the 2nd main lip 88 of present embodiment and the lip of the 2nd secondary lip 94) also except so-called main lip with the secondary lip mainly preventing dust and dirt or rubbish etc. from reductor outside from invading, or there are three lip oil sealings (only possessing the oil sealing of the lip of the 2nd main lip 88, the 2nd secondary lip 94 and the 1st secondary main lip 92 that are equivalent to present embodiment) etc. that the abrasive dust prevented in reductor etc. enters into the dust lip in oil sealing further compare, the sealing function that reliability is higher can be played.
And, this oil sealing 80 is owing to having single outside annulus 82, therefore (such as, compared with the structure be arranged vertically merely with 2 oil sealings of the half by axial width being this oil sealing 80) even if be identical axial width generally, also can maintain the intensity of annulus 82 outside this higher, and the assembling intensity that can maintain oil sealing is higher namely to the main body 50A of housing 50() assembling force.Therefore, though reductor 36 housing 50 and produce axial relative infinitesimal deflection between output shaft 58, also oil sealing 80 can be locked to housing 50 side securely.
Further, the feedway 12 involved by present embodiment so can guarantee higher sealing function by oil sealing 80, therefore about bearing 62,64, adopts the opening bearing without sealing element to reduce to realize corresponding cost.
In addition, in above-mentioned embodiment, 1st main lip 86, the 2nd main lip 88 both sides all possess the force application mechanism based on spring 90, but the force application mechanism based on spring may not be set up as necessary condition by main lip involved in the present invention, also can by the reinforcing utilizing the force application mechanism (utilizing the counteractive force application component of the elastic deformation relative to lip) of so-called " interference fit " provide the abutting of main lip.In addition, the present invention plays the structure of the main lip of main seal effect for having " 2 ", different from the past is attached to the secondary lip of the magnitude of interference and main lip " different " or the structure of dust lip.
In addition, in the above-described embodiment, 2 the 1st main lips 86, the 2nd main lips 88 are same shape, have the force application component based on identical spring 90,91 and abut towards with output shaft 58 with identical relative to bearing 62,64.Namely, although be assembled with the 1st main lip 86, the 2nd main lip 88 that 2 have identical structure and sealing function side by side, but in the present invention, in brief, as long as possess as this oil sealing the main lip that 2 have main and equal sealing function, shape or force application component etc. are without the need to identical.If such as afterburning identical, then a main lip can be have the force application component based on spring, and another main lip can be have the force application component based on interference fit.Further, the configuration of 2 main lips is towards also unnecessary identical, and such as one can configure towards bearing side, and another can configure towards bearing opposition side.
And, the present invention is as illustrated in above-mentioned embodiment, such as a result when gear motor 18 by can be fixed into the torque arm connect mechanism 32 that cannot move axially relatively be linked to the fixed mount (fixed parts) 30 of conveying mechanism 16 time, the most significant action effect can be obtained, but this gear motor not necessarily to cannot be linked as necessary condition to (or have the worry that the is fixed) connect mechanism moved axially by gear motor being fixed into by the present invention.That is, gear motor is linked to fixed parts feedway by the connect mechanism linked with the state that can produce infinitesimal deflection in the axial direction is also applicable to.
And, in above-mentioned embodiment, there is extension that the axle drive shaft self being equivalent to conveying mechanism installs gear motor degree at the very start, but axle drive shaft involved in the present invention (possesses extension) without the need to one being decided to be single part, even if utilize adaptor union that other spindle units etc. are linked to axle drive shaft with coaxial manner, and this spindle unit is inserted in the output shaft of reductor, (same problem occurs) also effectively can be suitable for the present invention's (belonging to category of the present invention).With this viewpoint, the output shaft for the reductor of the gear motor of feedway involved in the present invention is not necessarily made up of the hollow output shaft with hollow bulb.Such as, also can be reductor output shaft this as solid, and utilize the structure that adaptor union etc. links with coaxial manner and axle drive shaft.
Further, exemplify belt conveyor in above-mentioned embodiment and be wound in feedway on the axle drive shaft of conveying mechanism, but the conveying mechanism of feedway involved in the present invention is not limited to this.Such as, also can be following roller path structure: between multiple axle drive shafts of arrangement in parallel, possess idler shaft, with every one or more mode configuration driven axle, according to the rotation of axle drive shaft, transported substance limit and this axle drive shaft and the direct contact edge of idler shaft are carried.
And, as above-mentioned embodiment, the present invention be applicable to transported substance P1, P2 ... during the feedway of the type that the axle drive shaft 14 that the output shaft 58 with gear motor 18 links with coaxial manner passes through, (be directly delivered to output shaft 58 owing to effectively can prevent the vibration etc. from this axle drive shaft 14 and) is effective especially, but the present invention is not necessary to be applicable to the type that transported substance passes through on the driving shaft, even but axle drive shaft is configured to can be suitable for too away from the feedway of conveyor surface, and corresponding effect can be obtained.
In brief, any axle drive shaft carries out all there is same problem in the feedway of the structure driven by having with the gear motor of the output shaft that this axle drive shaft links with coaxial manner, can obtain action effect same as described above by being suitable for the present invention.
