Embodiment
Below, the example to embodiments of the present invention is elaborated with reference to the accompanying drawings.
Fig. 1 is that an example of expression embodiments of the present invention related feedway and part comprise that the plan view that amplifies the cross section, Fig. 2 are the plan views of above-mentioned feedway, and Fig. 3 is the major component amplification sectional view of Fig. 1.
This feedway 12 possesses conveying equipment 16 with live axle 14 and the gear motor 18 that drives this live axle 14.Be fixed with driving wheel 22 by key 20 on the live axle 14.Though not shown, lean on the right side of the paper of Fig. 1 and Fig. 2 to be provided with follower, between this driving wheel 22 and follower, be wound with conveying belt 24 annularly.
In addition, as shown in Figure 2, this transported substance P1, P2 ... mounting is on conveying belt 24 and be transferred.Also describe as Fig. 2, transported substance P1, P2 ... may not constitute " directly over (promptly axle as character express go up C1) " of mounting in live axle 14, even as the conveying belt 24 of reeling on the present embodiment live axle 14, transported substance P1, P2 ... the situation of mounting on this conveying belt 24 also is contained in the notion of " transported substance passes through on live axle " among the present invention.Fixing frame (fixed component) 30(that live axle 14 is rotatably freely supported on conveying equipment 16 by bearing 25,26 is fixed in the parts 30A of fixing frame).
Below the structure of gear motor 18 is described.
The front end of the motor drive shaft 34A of motor 34 is formed with hypoid small gear 38.Hypoid small gear 38 and hypoid gear 40 engagements.Hypoid gear 40 is fixed in jack shaft 42 by key 44.Jack shaft 42 is rotatably freely supported on the housing body 50A of the housing 50 of (gear motor 18) speed reducer 36 by pair of bearings 46,48.In addition, housing 50 substitutes and only illustrate the through bolt hole with same-sign 51 in Fig. 2 by having omitted mark in the through bolt 51(accompanying drawing) link housing body 50A and case cover 50B.
Be fixed with spur wheel 54 by key 52 on the jack shaft 42.Spur wheel 54 and output gear 56 engagements.Output gear 56 is fixed in output shaft 58 by key 60.
In this mode of execution, adopt the opening bearing (not being so-called stuffing box bearing) that does not have sealed member to be used as bearing 62,64 with sealed member.The outer ring 62A of load side bearing 62 and the stepped part 50A1 butt that is formed at housing body 50A.And, the inner ring 62B of load side bearing 62 and described output gear 56 butts, output gear 56 and the stepped part 58C butt that is formed at output shaft 58.
On the other hand, the outer ring 64A of load opposition side bearing 64 and the stepped part 50B1 butt that is arranged at case cover 50B, inner ring 64B and the projection 58D butt that is arranged at output shaft 58.
The stepped part 14D butt of output shaft 58 one ends and live axle 14.Thus, by bolt 70 is screwed into the screw 14S that is formed at live axle 14 across the lid 66 with the end 58E butt of output shaft 58, the end face 14C and the distance L between the lid 66 1 of live axle 14 are shortened, thereby live axle 14 and output shaft 58 can be firmly fixed vertically.
As described above, in this mode of execution, gear motor 18 links by the fixing frame (fixed component) 30 of torque arm connect mechanism 32 with conveying equipment 16.
When being installed on the gear motor 18 of live axle 14 of feedway 12 with coaxial manner, in case direct revolution motor axle 34A, then live axle 14 rotations of conveying equipment 16 (be not but) makes whole gear motor 18 around live axle 14 rotations because of reaction.To link the housing 50 of gear motor 18 in order to prevent this phenomenon and the fixing frame 30 of conveying equipment 16 is that purpose is used torque arm connect mechanism 32.
In this mode of execution, torque arm connect mechanism 32 by torque arm 72, be used for this torque arm 72 fastening jointly/be fixed in the main body 50A of housing 50(of the speed reducer 36 of gear motor 18) described through bolt (only illustrating the through bolt hole) 51, bolt 74, nut 75 and the pad 76 that is used for torque arm 72 is fixed in the fixing frame 30 of conveying equipment 16 constitute.
Particularly, as Fig. 1～related torque arm 72 of this mode of execution shown in Figure 3, be the general triangular shape when observing with main looking, bend to when observing to overlook of bonding with aim at and the link surface 72A of gear motor 18 and and the link surface 72B of fixing frame 30 between distance L 2.Thus, can with the stationary plane 30B of the fixing frame 30 of conveying equipment 16 and the stationary plane 50A2 both sides butt of housing body 50A.
Also as can be known clear and definite from Fig. 1, Fig. 3, the link surface 72A of housing 50 sides of torque arm 72 directly contacts with the stationary plane 50A2 of housing body 50A in this mode of execution.And the link surface 72B of fixing frame 30 sides of torque arm 72 directly contacts with the stationary plane 30B of the fixing frame 30 of conveying equipment 16.And torque arm 72 is firmly fixed at housing 50 by through bolt 51, bolt 74, nut 75 and pad 76 and fixing frame 30(torque arm 72 all is fixed into and can't moves axially relatively with housing 50 with fixing frame 30, torque arm 72).In other words, this gear motor 18 is by the housing 50 of fixing frame (fixed component) 30 of conveying equipment 16 and gear motor 18 being fixed into the torque arm connect mechanism 32 that can't move axially relatively and (in fact can't movably vertically) be fixed in the fixing frame 30 of conveying equipment 16.
As stating, in this kind feedway 12, the connect mechanism that uses torque arm 72 is the necessary constitutive requirements that are used to prevent the phenomenon of this gear motor 18 self rotation, but link example as this, if the housing 50 of the fixing frame 30 of conveying equipment 16 and gear motor 18 ground (can't infinitesimal deflection ground) of not leaving no room is firmly fixed, then because the live axle 14 of conveying equipment 16 moves the output shaft 58 that makes speed reducer 36 when mobile vertically vertically, (owing to housing 50 integral body of gear motor 18 can't be followed moving of this output shaft 58) must not only absorb this infinitesimal deflection by relatively moving between housing 50 and the output shaft 58.Therefore, as above-mentioned binding form, be actually unfavorable as the binding form of torque arm 72.About the binding of torque arm 72, preferably be mounted to vertically and have " play " a little, so that the housing 50 of gear motor 18 can carry out infinitesimal deflection vertically with respect to the fixing frame 30 of conveying equipment 16.That is, even the torque arm connect mechanism 32 related as this mode of execution is actual when linking by this torque arm connect mechanism 32, also preferred with nut 75 to stop under the state that is not fastened to the end.
Yet the installation of torque arm connect mechanism 32 usually has to become field operation because of the position with the fixing frame 30 of conveying equipment 16 concerns, also will entrust in the user side sometimes.And, often take place in the middle of the reality, though MANUFACTURER install, but after user side's inspection in, make the housing 50 of gear motor 18 can't be linked to fixing frame 30 at last owing to nut 75 is fastened to by torque arm 72 with moving axially.
Checking according to inventors learns that unfavorable conditions such as the oiling agent leakage of this kind feedway 12 especially take place easily in this situation.The words of understanding from other viewpoints, the present invention can be called: result from the phenomenon that must cause in the housing 50 and the axial vibration between the output shaft 58 of gear motor 18 or the feedway that is considered to use by this way that relatively moves, when being used by this way,, adopted undesirable conditions such as oiling agent leakage the invention of " considering the oil sealing of the structure of the distinctive situation of feedway " for being produced.
In this mode of execution, the oil sealing 80,81 that is disposed between output shaft 58 and the housing 50 has: be arranged at the axial outside of bearing 62,64 and single metal outside annulus 82 and be arranged at from this outside annulus 82 inwardly week side- prominent support 83,84 2 the 1st main lip the 86, the 2nd main lips 88 of synthetic rubber system of front end.In addition, the oil sealing 81 of load side is the oil sealing 80 identical parts with the load opposition side, and only be mounted in the axial direction towards on the contrary.
The oil sealing 80 that is conceived to the load opposition side describes, though this oil sealing 80 has 2 the 1st main lip the 86, the 2nd main lips 88, metal outside annulus 82 is " 1 ", and as the parts that are called oil sealing 80, extremely whole to the beginning is 1 parts.
The 1st main lip the 86, the 2nd main lip 88 of oil sealing 80 is taken on main effect in the sealing function of this oil sealing 80.The 1st main lip the 86, the 2nd main lip 88 both sides all with respect to bearing 62,64 with equidirectional, is about to the oil form that the leakages outside speed reducer 36 seal well in the speed reducer 36 and arranges, and each has living shape.And the 1st main lip the 86, the 2nd main lip 88 has respectively and is used for the identical spring (force application mechanism) 90,91 of the 1st main lip the 86, the 2nd main lip 88 to output shaft 58 application of forces.The load opposition side that the load opposition side of the 1st main lip 86 is provided with the 1st secondary lip 92, the 2 main lips 88 is provided with the 2nd secondary lip 94 identical with the 1st secondary lip 92.Promptly this oil sealing 80 contacts with output shaft 58 at 4 places altogether.
Then, the effect to this feedway 12 describes.
The related feedway 12 of this mode of execution by this be used for carrying transported substance P1, P2 ..., therefore can't prevent the vibration that takes place because of conveying equipment 16 sides or mounting transported substance P1, P2 ... the time impact especially live axle 14 axially on the thrust load that applies etc. and the phenomenon generation that live axle 14 vibrate vertically or move.And, be difficult to also prevent that the axial mobile phenomenon that is directly delivered to the output shaft 58 of speed reducer 36 of this live axle 14 from taking place.And, in this mode of execution, though gear motor 18(is undesirable as a result of) be fixed in the fixing frame 30 of conveying equipment 16 by torque arm connect mechanism 32, wherein torque arm connect mechanism 32 is fixed into the housing 50 of the speed reducer 36 of the fixing frame 30 of conveying equipment 16 and this gear motor 18 can't move axially relatively.Therefore, as long as have the vibration of live axle 14 or axial infinitesimal deflection to be input to output shaft 58(because the housing 50 of speed reducer 36 is firmly fixed at fixing frame 30), then the vibration of this live axle 14 or axial infinitesimal deflection all show as relative vibration or the relative infinitesimal deflection between the housing 50 of output shaft 58 and speed reducer 36.Therefore, oil sealing 80,81 also is exposed under the very harsh state.
Yet, adopted the oil sealing 80 that is arranged with 2 the 1st main lip the 86, the 2nd main lips 88 in the present embodiment.The 1st main lip the 86, the 2nd main lip 88 both sides all with respect to bearing 62,64 with equidirectional, promptly so that oil is arranged from the form that speed reducer 36 interior leakages outside speed reducer 36 seal well, and, both sides all by the reinforcing that produces by spring 90 with the periphery butt of output shaft 58.Therefore sealability is extremely high.And the 1st main lip the 86, the 2nd main lip 88 possesses the 1st secondary lip the 92, the 2nd secondary lip 94 respectively.Therefore, in the 1st main lip 86 and the 1st secondary lip 92, at first carry out standard seal.And, if even in the 1st main lip 86 and the 1st secondary lip 92, do not seal fully, in the 2nd main lip 88 and the 2nd secondary lip 94, also carry out standard seal once more, so its result, very powerful sealing function can be kept for a long time.In this, with except that so-called main lip, also have the two-lip seal that mainly prevents from the secondary lip of intrusions such as the dust and dirt of speed reducer outside or rubbish (oil sealing that only possesses the lip of the 2nd main lip 88 that is equivalent to present embodiment and the 2nd secondary lip 94), or further have the three lip oil sealings (oil sealing that only possesses the lip of the 2nd main lip the 88, the 2nd secondary lip 94 that is equivalent to present embodiment and the 1st secondary main lip 92) etc. that the abrasive dust that prevents in the speed reducer etc. enters into the dust lip in the oil sealing and compare, can bring into play the higher sealing function of reliability.
And, this oil sealing 80 is owing to have single outside annulus 82, therefore (for example, with axial width is compared for half the simple structure of alignment arrangements vertically of 2 oil sealings of this oil sealing 80) even be identical axial width generally, also can keep the intensity of this outside annulus 82 than the highland, and the assembling intensity that can keep oil sealing than the highland is promptly to the main body 50A of housing 50() assembling force.Therefore, even between the housing 50 of speed reducer 36 and output shaft 58, produce axial relative infinitesimal deflection, also oil sealing 80 can be limited to securely housing 50 sides.
And,,, adopt the opening bearing that does not have sealed member to realize that corresponding cost reduces therefore about bearing 62,64 because the related feedway 12 of present embodiment can so be guaranteed higher sealing function by oil sealing 80.
In addition, in the above-mentioned mode of execution, the 1st main lip the 86, the 2nd main lip 88 both sides all possess the force application mechanism based on spring 90, but main lip involved in the present invention may not also can provide the reinforcing of the butt of main lip by the force application mechanism (utilizing the counteractive force application component with respect to the resiliently deformable of lip) that utilizes so-called " interference fit " with based on the setting up as necessary condition of the force application mechanism of spring.In addition, the present invention is for having the structure that " 2 " bring into play the main lip of main seal action, the secondary lip of setting up magnitude of interference and main lip " different " different from the past or the structure of dust lip.
In addition, in the above-described embodiment, 2 the 1st main lip the 86, the 2nd main lips 88 are identical shaped, have based on the force application component of identical spring 90,91 and with respect to bearing 62,64 with identical towards with output shaft 58 butts.Promptly, though be assembled with 2 the 1st main lip the 86, the 2nd main lips 88 side by side with identical structure and sealing function, but in the present invention, in brief, as long as possess 2 main lips with main and equal sealing function as this oil sealing, shape or force application component etc. need not identical.For example if afterburning identical, then a main lip can be the force application component that has based on spring, and another main lip can be the force application component that has based on interference fit.And the configuration of 2 main lips is towards also unnecessary identical, and for example one can be disposed towards the bearing side, and another can dispose towards the bearing opposition side.
And, illustration in the present invention such as the above-mentioned mode of execution, for example as a result of when gear motor 18 by being fixed into the torque arm connect mechanism 32 that can't move axially relatively when being linked to the fixing frame (fixed component) 30 of conveying equipment 16, can obtain the most significant action effect, but the present invention to can't link this gear motor as necessary condition by gear motor being fixed into not necessarily to axially movable (or have the worry that is fixed) connect mechanism.That is, also be linked to the feedway of fixed component by the connect mechanism that links with the state that can produce infinitesimal deflection in the axial direction applicable to gear motor.
And, in the above-mentioned mode of execution, the extending portion that has live axle self the mounting teeth wheel motor degree that is equivalent to conveying equipment at the very start, but live axle involved in the present invention need not one to be decided to be (possessing extending portion) single part, even utilize connector that other spindle units etc. are linked to live axle with coaxial manner, and this spindle unit is inserted in the output shaft of speed reducer, and (same problem takes place) also can effectively be suitable for the present invention's (belonging to category of the present invention).With this viewpoint, the output shaft of speed reducer that is used for the gear motor of feedway involved in the present invention may not necessarily be made of the hollow output shaft with hollow portion.For example, also can for the output shaft of speed reducer this as solid, and utilize connector etc. with the structure of coaxial manner with the live axle binding.
And example illustrates the feedway on the live axle that conveying belt is wound in conveying equipment in the above-mentioned mode of execution, but the conveying equipment of feedway involved in the present invention is not limited to this.For example, also can be following roller conveyor mechanism: between a plurality of live axles that are arranged in parallel, possess idler shaft, with mode configuration driven axle, transported substance limit and this live axle and the direct contact edge of idler shaft are carried according to the rotation of live axle every one or more.
And, as above-mentioned mode of execution, the present invention be applicable to transported substance P1, P2 ... during the feedway of the type of on the live axle 14 that links with coaxial manner with the output shaft 58 of gear motor 18, passing through, (since can effectively prevent from the vibration of this live axle 14 etc. be directly delivered to output shaft 58 and) effective especially, but the present invention is not necessary to the type that is applicable to that transported substance passes through on live axle, even but live axle is configured to can be suitable for too away from the feedway of conveyor surface, and can obtain corresponding effects.
In brief, all there is same problem in the feedway of the structure that any live axle drives by the gear motor with the output shaft that links with coaxial manner with this live axle, can accesses action effect same as described above by being suitable for the present invention.
The application advocates the preference based on the Japanese patent application of on January 31st, 2012 application 2012-017489 number.All the elements of its application are applied in this specification by reference.
