Description
Technical field
The present invention relates to a kind of gear motor (gear reduction unit).
Background technology
The gear motor that reductor and motor link is disclosed in patent documentation 1.
The motor of this gear motor possesses the fan of cooling.Further, the shell of motor or the shell of reductor are formed by linking multiple housing.
Patent documentation 1: Japanese Unexamined Patent Publication 2007-301950 publication
Usually, in motor and reductor, being generally that motor easily generates heat and causes oil film breakage etc. when identical temperature, is generally that reductor is often in serious situation.Therefore, it is preferred near this motor, arranging cooling fan from qualitative, and there is the tendency becoming higher temperature in the motor-side of the tendency having heat load stronger, the generation of the heat therefore in fact not between special concern motor and reductor or conduction.
Summary of the invention
The present invention completes by considering the part of not gazing at contact up hill and dale according to the Development trend of gear motor in recent years, and its problem is by utilizing the heat of high efficiency motor and the reductor starting especially in recent years to popularize to produce dexterously or conduction mechanism suppresses the heating of gear motor entirety effectively.
The present invention solves above-mentioned problem by being set to following structure, the gear motor that a kind of motor and reductor link, the shell of described gear motor is made up of multiple housing, and in the link surface between this housing, at least 1 link surface except the housing link surface each other of described motor sandwiches the seal member of this link surface of configuration sealing, configure heat transfer component sandwiching on the link surface near described motor in the link surface being configured with sealing parts, described heat transfer component contacts with the described housing both sides of the both sides being positioned at this link surface, and described heat transfer component is formed by the raw material of thermal conductivity higher than described seal member.
The present invention is conceived to the high efficiency motor (when exporting identical) that substantially starts in recent years to popularize, and caloric value is less and easily decline on the contrary relative to reductor relative temperature than ever.That is, the heat being conceived to the reductor by relatively becoming higher heat in the present invention is passed to motor-side and the mechanism of dispelling the heat through the housing of motor on one's own initiative.
But with regard to reductor, in order to ensure sealing, the link surface between housing often sandwiches the seal members such as configuration (being specifically coating) liquid fillers.If sealing parts are arranged on the link surface between housing, then because of seal member thermal conductivity great disparity lower than the raw material of housing, so cause the heat conduction smoothly from reductor side to motor-side to be obstructed.
Therefore, link surface between middle shell of the present invention by be provided with seal member link surface (after, conveniently be called sealing link surface) when forming, at least to be formed near the sealing link surface of motor configures heat transfer component mode, wherein, described heat transfer component contacts with the housing both sides of the both sides being positioned at sealing link surface and is formed by the raw material of thermal conductivity higher than seal member.
Thus, though when link surface by seal link surface form, also the heat of deceleration pusher side can be guided to motor-side swimmingly through heat transfer component, effectively can reduce the heat of overall gear motor.

Embodiment
Below, with reference to the accompanying drawings an example of embodiments of the present invention is described in detail.
Fig. 1 is the cutaway view of the structure (along Fig. 2 to looking I-I line) of the gear motor of the example representing embodiments of the present invention, and Fig. 2 is the end view of this gear motor.
This gear motor GM1 is the motor that motor M1 and reductor G1 link integratedly.
In this execution mode, adopt so-called high efficiency (Ultra-High Efficiency) motor being suitable for IE3 specification as motor M1.
IE3 specification is in recent years for the motor rotated with constant speed, based on IEC(International Electrotechnical Commission) 60034-2-1 is at one of the level of efficiency of the computational methods of distribution in 2007.At this level of efficiency for efficiency fiducial value to be formed by grade separation, from the highest efficiency, regulation has IE4(to surpass Ultra-High Efficiency), IE3(Ultra-High Efficiency), IE2(high efficiency), IE1(standard performance).
Usually, there will be a known for the effective ways improving moyor: such as, (1) is set to the motor used as the magnet of IPM or SPM and so on; (2) raw material (material) of the component parts such as magnetic core or spiral are changed; (3) thickness of coil spiral or method for winding (shape of groove) etc. are changed; (4) streaming current is suppressed for less etc.
No matter use any method, from IE1 to IE2, from IE2 to IE3 ... more becoming high efficiency, when obtaining identical output, having the tendency that the heat of generation reduces.Employ the standard motor being equivalent to IE1 as motor, so be generally that motor becomes " heater " compared with reductor in the past.But high efficiency motor is less due to caloric value, may on the contrary as the situation that temperature plays a role lower than " radiator " of reductor so be in.
Present embodiment maximally utilises this directed trend, promotes energetically " from the reductor to motor transferring heat " that be difficult to expect in the past.
Below, be described one by one from the structure of the shell Cgm of gear motor GM1.
The shell Cgm of this gear motor GM1 is made up of the 1st ~ 5th housing 11 ~ 15.1st housing 11 forms the end cap of motor M1.2nd housing 12 holds the main body of the motor M1 such as stator 20 and rotor 22.3rd housing 13 forms the front shroud of motor M1, and doubles as the side cover of reductor G1.4th housing 14 holds the reducing gear of reductor G1.5th housing 15 supports the output shaft described later 28 of reductor G1.
1st ~ 3rd housing 11 ~ 13 forms the shell Cm of motor M1.Further, the 3rd ~ 5th housing 13 ~ 15 forms the shell Cg of reductor G1.That is, the 3rd housing 13 is a part of the shell Cm of motor M1, and is a part of shell Cg of reductor G1.
1st ~ 3rd housing 11 ~ 13 is linked by through bolt 30.Due to the lubricant by oil sealing 97 seal speed reducer G1 on 2nd link surface 42 of the 1st link surface 41 of the 1st housing 11 and the 2nd housing 12, the 2nd housing 12 and the 3rd housing 13, and almost do not have lubricant to immerse the risk of the 2nd link surface 42, so do not arrange seal member especially.That is, in this execution mode, in housing 11 ~ 13 link surface i.e. the 1st link surface 41 each other of motor M1, the 2nd link surface 42, metal is in direct contact with one another, and maintains high thermal conductivity.
In addition, motor M1 is high efficiency (Ultra-High Efficiency) motor of IE3 specification, and therefore overall dimensions is large a little compared with the standard motor of IE1 specification in the past.Its result, the thermal capacity of shell Cm correspondingly becomes large, and area of dissipation also becomes large.Therefore, except the caloric value of motor M1 itself is less, thermal diffusivity itself was also higher than in the past.This tendency is highly advantageously playing a role as a result for releasing in the present embodiment of the heat of reductor G1 side through the shell Cm of motor M1.
On the other hand, on the 3rd link surface 43 between the 3rd housing 13 and the 4th housing 14, for seal (specifically, will the seals lubricant in reductor G1 be enclosed) between the 3rd housing 13 and the 4th housing 14 and sandwiches seal member Se(such as configuring (being specially coating) liquid fillers not shown).Further, the 4th link surface 44 between the 4th housing 14 and the 5th housing 15 sandwiches too and configures seal member Se.Conveniently, will the 3rd link surface 43 that is configured with seal member Se be sandwiched and the 4th link surface 44 is called " sealing the 3rd link surface 43 " and " sealing the 4th link surface 44 " later.
In this execution mode, seal the 3rd link surface 43 and sealing the 4th link surface 44 be equivalent to " housing of motor each other beyond link surface and sandwich the link surface being configured with seal member ", wherein, seal the 3rd link surface 43 to be equivalent to " link surface near motor ".
As enlarged icon in Fig. 3, in present embodiment, (being coated with seal member Se's) sealing the 3rd link surface 43 is configured with transfer pin of heat (heat transfer component) 50, and described transfer pin of heat contacts (with reference to figure 2) with the 4th housing 14 both sides with the 3rd housing 13 of the both sides being positioned at sealing the 3rd link surface 43.Transfer pin of heat 50 is configured in intercommunicating pore 13B, 14B, the 15B different from bolt hole 13A, 14A, the 15A of the binder bolt 52 for linking the 3rd ~ 5th housing 13 ~ 15.Specifically, avoid the rib 15H of the foot 15F of the 5th housing 15 and circumferentially configure 6.Further, the outer peripheral face entirety of transfer pin of heat 50 contacts with the inner peripheral surface of intercommunicating pore 13B, 14B, 15B.
Transfer pin of heat 50 is formed by the raw material (such as Ferrious material) of thermal conductivity higher than seal member Se.This transfer pin of heat 50 is arranged throughout multiple link surface (sealing the 3rd link surface 43 and sealing the 4th link surface 44), not only play a role as the heat transfer component between the 3rd housing 13 and the 4th housing 14, but also play a role as the heat transfer component between the 4th housing 14 and the 5th housing 15.
On the other hand, as enlarged icon in Fig. 4, the 3rd ~ 5th housing 13 ~ 15 is linked by 1 (reductor G1 on the whole exists 8 with 45 ° of intervals: with reference to figure 2) binder bolt 52.Specifically, before binder bolt 52, end-grain cutting has external screw thread 52A, the 3rd housing 13 is provided with and forms female bolt hole 13A.Binder bolt 52 inserts from the bolt hole 15A side of the 5th shell 15 and the part of this external screw thread 52A of this binder bolt 52 is screwed into bolt hole 13A.
In present embodiment, be configured with the packing ring (heat transfer component) 54 of thermal conductivity higher than the Ferrious material of seal member Se in the periphery of this binder bolt 52.If be conceived to sealing the 3rd link surface 43, then the periphery of binder bolt 52 that this structure can be interpreted as at link the 3rd housing 13, the 4th housing 14 is configured with the high packing ring of the coefficient of overall heat transmission 54.Further, if be conceived to sealing the 4th link surface 44, then can be interpreted as that the periphery of the binder bolt 52 at link the 4th housing 14, the 5th housing 15 is configured with the high packing ring of the coefficient of overall heat transmission 54.
Flange part (wide diameter portion) 54A clamped by the 3rd housing 13 of the both sides that are positioned at sealing the 3rd link surface 43 and the 4th housing 14 is formed in the end of packing ring 54.The outer peripheral face of packing ring 54 contacts with the inner peripheral surface of bolt hole 14A, 15A of binder bolt 52.
In addition, on the 5th housing 15 by binder bolt 52 be together fastened with double as deep bead boatswain chair 56(with reference to figure 1, with reference to figure 2).
The structure of motor and reductor is not particularly limited in the present invention, at this, the motor M1 of this execution mode and the structure of reductor G1 is described.
The motor drive shaft 58 of motor M1 is by being installed on the seal ball bearing 62 of the 1st housing 11 and being installed on the seal ball bearing 64 of the 3rd housing 13 and rotatably being supported.The deceleration pusher side of this motor drive shaft 58 exceeds the 3rd housing 13 and outstanding extension in reductor G1, and its power shaft 66(forming reductor G1 doubles as the power shaft 66 of reductor G1).Further, the reductor opposition side of this motor 58 exceed the 1st housing 11 and to motor M1 extension protruding outside and have cooling fan 68 at its end winding support.Cooling fan 68 is contained in and is formed in the fan case 70 of ventilating opening 70A.
On the other hand, as reductor G1, in this execution mode, adopt the planetary reducer possessing oscillating internal engagement type planetary gear reducing mechanism.
With motor drive shaft 58 all-in-one-piece power shaft 66 by described seal ball bearing 64 and ball bearing 72 by two-end bearing support.Power shaft 66 is fixed with through key 76 eccentric body 74,75 relative to the eccentric δ e in the axle center of this power shaft 66.Eccentric body 74,75 arrange two and each eccentric body 74,75 to have the eccentric phase of 180 degree poor.In the periphery of eccentric body 74,75 through roller bearing 80, roller bearing 81 and swing rotary is provided with external gear 82,83 freely.External gear 82,83 internal messing is in internal gear 86.
Internal gear 86 comprises: with the 4th housing 14 all-in-one-piece internal gear main body 86A, form the outer roller 86B of internal tooth and this outer roller 86B be rotatably freely supported on the export trade 86C of internal gear main body 86A.The interior number of teeth (radical of outer roller 86B) of internal gear 86 is more more a little than the outer number of teeth of external gear 82,83 (in this execution mode being many 1).
Be formed with interior roller hole 82A, 83A at external gear 82,83 from the position of its off-centring, domestic 90 run through this interior roller hole 82A, 83A.Domestic 90 are put as roller 92 in slip promotion body.Interior roller 92 and the interior gap of 2 times guaranteeing to have the offset δ e being equivalent to eccentric body 74,75 between roller hole 82A, 83A.Domestic 90 press-ins are fixed on and described output shaft 28 all-in-one-piece flange body 28A.Flange body 28A supports be pressed into fixed domestic 90 with cantilever position, and supports one end of power shaft 66 through described ball bearing 72.
Output shaft 28 is supported on the 5th housing 15 by a pair ball bearing 94,95.5th housing 15 is integrally formed with the foot 15F of the pedestal 96 for this reductor G1 being assemblied in ground or object machinery etc.In addition, the symbol 97,98 of accompanying drawing is oil sealing.
Then, the effect of this gear motor is described.
If the motor drive shaft 58 of motor M1 rotates, then rotate with the power shaft 66 of this motor drive shaft 58 all-in-one-piece reductor G1.If power shaft 66 rotates, then eccentric body 74,75 and this power shaft 66 rotate integratedly, make external gear 82,83 swing rotary through roller bearing 80,81.The phenomenon that the position of engagement of its result generation external gear 82,83 and internal gear 86 is departed from successively.The number of teeth due to external gear 82,83 is set to the number of teeth (radical of outer roller 86B) only few 1 than internal gear 86, so external gear 82,83 only departs from (rotation) phase place suitable with a tooth amount relative to (being in stationary state) internal gear 86 when power shaft 66 often rotates 1 time.This rotation composition is passed to flange body 28A through domestic 90 and interior roller 92, and is passed to the output shaft 28 with this flange body 28A integralization.In addition, the swing composition of external gear 82,83 is absorbed by interior roller 92 and interior gap between roller hole 82A, 83A.
At this, if run gear motor GM1, then motor M1 and reductor G1 can generate heat.But, in present embodiment, motor M1 owing to adopting high efficiency (Ultra-High Efficiency) motor of IE3 specification, so compared with standard motor (motor of IE1 specification) in the past, the heat produced in motor M1 is extremely few.Therefore, heat is produced for from reductor G1 effluent to the situation of motor M1 side.During the gear motor of structure in the past, even if this thing happens, also because the 3rd link surface 43 between the 3rd housing 13 and the 4th housing 14 and the 4th link surface 44 between the 4th housing 14 and the 5th housing 15 form (sandwich and be configured with the lower seal member Se's of thermal conductivity) sealing link surface, so this heat flow is obstructed, the heat of reductor (G1) has to be in the situation keeping higher state.
But, in present embodiment, owing to being configured with transfer pin of heat 50 and packing ring 54 near on sealing the 3rd link surface 43 of motor M1, described transfer pin of heat and packing ring be positioned at the 3rd housing 13 of both sides of sealing the 3rd link surface 43, the 4th housing 14 both sides contact, and formed by the raw material of thermal conductivity higher than seal member Se, so no matter with or without seal member Se, namely the heat of the 4th housing 14 can both flow to the 3rd housing 13(through this transfer pin of heat 50 and packing ring 54, the shell Cm of motor M1 swimmingly) side.
In addition, in present embodiment, owing to being also configured with (identical) transfer pin of heat 50 and packing ring 54 on the 4th housing 14, the 5th housing 15 sealing each other the 4th link surface 44, described transfer pin of heat and packing ring be positioned at the 4th housing 14 of both sides of sealing the 4th link surface 44, the 5th housing 15 both sides contact, and formed by the raw material of thermal conductivity higher than seal member Se, so also can carry out extremely swimmingly through transfer pin of heat 50 and packing ring 54 from the 5th housing 15 to the heat transfer of the 4th housing 14.
Especially, in present embodiment, 5th housing the 15 ~ 3rd housing 13 is provided with single transfer pin of heat 50, and is formed with flange part (wide diameter portion) 54A clamped by the 3rd housing 13 and the 4th housing 14 in the end of packing ring 54, therefore, it is possible to more swimmingly to the 3rd housing 13 side transferring heat.
In addition, the heat that passes over to the 3rd housing 13 side (due to the 1st link surface 41 between the 1st ~ 3rd housing 11 ~ 13 of motor M1 side, the 2nd link surface 42 not being configured with seal member Se, so) can move to the 2nd housing 12, the 1st housing 11 side extremely like a cork.
The high efficiency motor of shell Cm owing to being IE3 specification of the motor M1 of present embodiment, thus caloric value itself less and compared with standard motor in the past size slightly large, therefore thermal capacity is comparatively large and area of dissipation is larger.Therefore, effectively cooled by cooling fan 68, can through shell Cm(the 1st ~ 3rd housing 11 ~ 13 of motor M1) release the heat of reductor G1 swimmingly.
In addition, in gear motor GM1 shown in Fig. 1,3rd ~ 5th housing 13 ~ 15 adopts and the binder bolt 52 cutting external screw thread 52A is screwed into (cutting female) the 3rd structure of bolt hole 13A of housing 13, but replace this structure, also can be the such as connecting structure combinationally using binder bolt 91 and nut 93 as shown in Figure 5.Now, owing to not cut screw thread between binder bolt 91 and the 3rd housing 13a, thus can using throughout the 3rd ~ 5th housing 13a, 14,15 and the packing ring 99 run through use as heat transfer component.In addition, packing ring 99 outer peripheral face and the 3rd ~ 5th housing 13a, 14, the inner peripheral surface of bolt hole 13aA, 14A, 15A of 15 contacts.
So, heat transfer component is not particularly limited its shape or raw material, quantity of formation etc.Such as, in above-mentioned execution mode, except transfer pin of heat, also assemble packing ring as heat transfer component, but may also be only any one party.For raw material, as long as its coefficient of overall heat transmission is higher than the coefficient of overall heat transmission of seal member, be not limited to metal.Such as, be the raw material of its after coagulation of semi-solid state when also can be inclosure.
But, in above-mentioned execution mode, have employed the reductor only possessing one-level oscillating internal engagement type planetary gear reducing mechanism as reductor G1, but in reductor, also have the such as reductor possessing the high retarding stage of heat load as shown in Figure 6.The present invention especially plays a role effectively to this gear motor possessing the high reductor G2 of heat load as shown in Figure 6.
Gear motor GM2 shown in Fig. 6 has high efficiency (IE3 specification) the motor M2(=M1 identical with the motor M1 of above execution mode).Further, the 1st retarding stage of reductor G2 is made up of the oscillating internal engagement type planetary gear reducing mechanism identical with above execution mode.Orthogonal reducing gear 102 is possessed further as the 2nd retarding stage unlike reductor G2 with above execution mode.
Specifically, compared with above execution mode, the output shaft 104 of the 1st retarding stage is hollow shaft, through spline 106, connecting axle 108 is linked to this output shaft 104.Bevel pinion 110 is formed in the front end of connecting axle 108.Bevel pinion 110 engages with bevel gear 112 and forms described orthogonal reducing gear 102.Bevel gear 112 links with hollow output shaft 120 through key 114.
According to this structure, in above execution mode not the 1st retarding stage of special applied thrust load output shaft 104 on be applied with the thrust load produced by the engagement of orthogonal reducing gear 102.For this reason, a pair tapered roller bearing 122,124 changed into by the ball bearing 94,95 of above execution mode.
And, 5th housing 115 is also in order to change into the shape of the flange portion 115A with large footpath with holding the 6th housing 116 of orthogonal reducing gear 102 to connect, and therefore the diameter d 1 of the axial central portion of the 5th housing 115 becomes the diameter d 2, d3(the 5th housing 115 that are less than direction of principal axis both ends and itself there is recess 115B).
The reductor G2 shown in Fig. 6 becoming this structure due to rolling element 122A, 124A of tapered roller bearing 122,124 bear radial load and thrust load both sides in linear contact lay mode while rotate, so the tendency that (although allowing that torque becomes large) has heating to become large.Especially, from Fig. 6 also known tapered roller bearing 122 due to be positioned at the 5th housing 115 recess 115B near, so heat easily accumulates and heat load uprises more.
But in this execution mode, the heat of the 5th housing 115 is identical with above execution mode, pass to the lower motor M2(=M1 of temperature through transfer pin of heat 50 and packing ring 54) shell Cm side.Therefore, it is possible to illustrate with from omitting in cooling fan 68(Fig. 6) cooling air cooperatively effectively release from the shell Cm of motor M2.
But in this execution mode, the 5th housing 115 and the 6th housing 116 ensure that sealing by O type ring 126.Therefore, in this embodiment, the 5th link surface 145 between the 5th housing 115 and the 6th housing 116 is not provided with seal member.Further, the 6th link surface 146 between the 7th housing 117 of the 6th housing 116 and (vicinity of the hollow output shaft 120 of inaccessible 6th housing 116) also guarantees there is sealing by O type ring 130.Therefore, in this execution mode, the 6th link surface 146 between the 6th housing 116 and the 7th housing 117 is not provided with seal member yet.Therefore, on the 5th link surface 145 as a result between the 5th ~ 7th housing 115 ~ 117, the 6th link surface 146, metal directly contacts each other substantially, ensure that higher thermal conductivity.
This is because in reductor G2 involved by the execution mode of Fig. 6,6th housing 116, the 7th housing 117 due to the rotating speed of held orthogonal reducing gear 102 also lower, heat load does not have that the 5th housing 115 is so excessive and its size is larger, therefore the larger heat radiation of thermal capacity is also carried out more well, so temperature is lower than the 5th housing 115 on the contrary when can imagine running.
That is, in this execution mode, the excessive heat of the 5th housing 115 flows to motor M2 side through the 4th housing 14, the 3rd housing 13, and flows to and the 6th housing 116 of the 5th housing 115 Metal Contact, the 7th housing 117 side, dispels the heat thus.
So, the unnecessary sealing link surface that all link surfaces of each housing must be set to (sandwich and be configured with seal member) in the present invention.Especially, about the shell of motor, due to guaranteeing that the requirement of sealing is little, so in order to guarantee that the conductivity of heat in the link surface between each housing is also preferably non-tight link surface (wherein higher, about the link surface of motor-side, such as, also can configure seal member and configure heat transfer component).And, in reductor, example such as shown in the execution mode of Fig. 6, about whether the link surface of each housing being set to sealing link surface, determines also can from the aspect such as simplification, sealing difficulty (tightness), the heat generation of reducing gear, the simplification of heat radiation of cost, assembling.
In a word, consider that the present invention is when link surface is set as the sealing link surface being provided with seal member from this various viewpoint, from carrying out the viewpoint of heat conduction between the housing of the both sides at sealing link surface well, especially, useful the viewpoint can carrying out heat conduction from reductor to motor-side well being in the past difficult to expect.In order to reliably ensure this effect, when in the present invention, the face of being tightly connected has multiple (in order to ensure from reductor to the heat transfer of motor-side or as described later in order to ensure from motor-side to the heat transfer of deceleration pusher side) must relatively wherein by the sealing link surface configuration heat transfer component of motor-side.But, not necessarily to configure heat transfer component to other sealing link surfaces.But in order to carry out the heat transfer of gear motor entirety more well, preferably the example of 2 execution modes described above all configures heat transfer component at all sealing link surfaces.
In addition, the present invention is the invention that when being conceived to employing high efficiency motor, the temperature of motor-side completes lower than this phenomenon of reductor on the contrary, but (even if adopting high efficiency motor), also makes the temperature of motor-side likely become higher because of the structure of reductor or the heat dissipation environment of holding gears motor.Now, in the present invention, in its structure, heat moves from motor-side to reductor side.But, even if there is this phenomenon, mobile heat and the temperature of gear motor entirety can be reduced to both medium temperature energetically between the motor of gear motor and reductor as a result, this viewpoint is never preferably do not act on, can thinks that the situation that can become beneficial effect is many on the contrary.
Namely, in the present invention, do not forbid in the structure of setting place or reducing gear when deceleration pusher side has unnecessary heat load such as making the heat produced in this standard motor flow to the uniform heat distribution that deceleration pusher side realizes gear motor entirety by using on the basis of standard motor.Therefore, the present invention only could set up when the structure of motor temperature step-down, and in this viewpoint, this is not necessary condition of the present invention must to use high efficiency motor.
The application advocates the priority of No. 2011-272779th, the Japanese patent application based on application on December 13rd, 2011.The full content of its application is by reference to being applied in this specification.
