Specifically, avoid this installed surface 30A in the front end mode be arranged on the limit S1 parallel with the installed surface 30A of terminal box 30 and be provided with 10 fin 32A (especially, with reference to figure 5) of slightly short length.Further, be arranged in two the limit S2s rectangular with installed surface 30A with front end, the mode of limit S4 is respectively arranged with 10 fin 32B, 32D, the mode being arranged in the limit S3 of the opposition side parallel with installed surface 30A further with front end is provided with 10 fin 32C.As above, if configuration fin 32A ~ 32D, then P1 ~ the P4 that has living space can be guaranteed near the summit of the tetragonal S of imagination.
In this execution mode, load-side cover 16 and load reverse side cover 18 possess 4 load-side base portion 22 and load reverse side base portion 24 respectively in the position being equivalent to this space P1 ~ P4.In addition, symbol 14A, 14B of Fig. 5, Fig. 6 are (reinforcement when the tightening through bolt) bearing block be arranged in chassis body 14, different from load-side base portion 22, load reverse side base portion 24.
Chassis body 14, load-side cover 16 and load reverse side cover 18 are linked by 1 (on the whole 4) through bolt 26 through this load-side base portion 22 and load reverse side base portion 24.As a result, protrusion 28 also can be positioned at the position near the summit of this imaginary tetragonal S.
In addition, in execution mode, although align in the front end of all fins on the limit of imagination quadrangle (square) S, its front end of part fin also comparable imaginary quadrangle enters more in the inner part.In other words, the maximum imagination quadrangle in the middle of the imagination quadrangle connected with the front end of each fin can also be shown as.
Apparent from each figure (especially Fig. 6), fin 32A ~ 32D does not form protrusion each other.In addition, fin 32A1,32B1,32C1, the 32D1 at fin 32A ~ 32D two ends of each limit S1 ~ S4 are integrated with adjacent protrusion 28.Describe in detail after structure about protrusion 28.
The side cover of load-side cover 16 dual-purpose reductor G1, and be arranged at the sidepiece of the axial load side of chassis body 14.As above-mentioned, load-side cover 16 position (the space P1 ~ P4 summit of imaginary tetragonal S near) corresponding with protrusion 28 in a circumferential direction possesses 4 load-side base portion 22 used when fastening through bolt 26 altogether.The screw 22A being screwed into through bolt 26 is formed in each load-side base portion 22.Load-side cover 16 is through shell 17 integralization of not shown bolt and reductor G1.
Load reverse side cover 18 is arranged at the sidepiece of the load reverse side of the axis of chassis body 14.The load reverse side cover 18 also position (the space P1 ~ P4 summit of imaginary tetragonal S near) corresponding with protrusion 28 in a circumferential direction possesses 4 load reverse side base portion 24 used when fastening through bolt 26 altogether.The through hole 24A (not being form screw) that through bolt 26 runs through is formed in each load reverse side base portion 24.Load reverse side cover 18 possesses opening (omitting diagram) in its radial central authorities, and cooling fan 19 links through the output shaft (omit and illustrate) of this opening and motor M1.Symbol 25 is fan guard.
4 through bolts 26 are used in this execution mode.The head 26A of each through bolt 26 abuts with the load reverse side base portion 24 of load reverse side cover 18.Further, through bolt 26 runs through the through hole 28A described later of the through hole 24A of this load reverse side base portion 24 and the protrusion 28 of chassis body 14 respectively, and its front end is screwed into the screw 22A of the load-side base portion 22 of load-side cover 16.Thus, chassis body 14, load-side cover 16 and load reverse side cover 18 are linked by 1 through bolt 26 through load-side base portion 22 and load reverse side base portion 24.
At this, the structure around protrusion 28 is described.4 protrusions 28 are same structure substantially.In this execution mode, as the miscellaneous part being installed on protrusion 28, prepare the framework (omitting diagram) be used at ground or equipment and install the foot 60 of motor M1 and the hanging bolt 70 for lifting by crane motor M1.The installation of the corresponding foot 60 of each protrusion 28 and both installations of hanging bolt 70.
In addition, in each accompanying drawing, foot 60 and hanging bolt 70 are all shown with 2, represent that from then on another 1 shown in the mounted state of 1 shown in inside solid, dotted line is about to mounted state respectively.
At each protrusion 28, run through the through hole 28A be formed with for inserted through through bolt 26 vertically.Further, as shown in Figure 6, each protrusion 28 possesses the installed surface 28A parallel with 2 limit S1, the limit S3 of the tetragonal S of described imagination and the installed surface 28B parallel with 2 limit S2, the limit S4 of imagination quadrangle S respectively.In addition, the top intersected at 2 installed surfaces 28A, 28B is formed with the chamfering 28C of 45 degree.The opposed distance L2 of installed surface 28A, 28B of each protrusion 28 and diagonal distance L4 is all less than length of side L3 and the diagonal length L5 of each limit S1 ~ S4 of imaginary tetragonal S, becomes protrusion 28 and is converged in size in imaginary tetragonal S.
2 spot-facing portions (engaged part) 52 are formed at each installed surface 28A, 28B.That is, spot-facing portion 52 is formed with 4 altogether by each protrusion 28, is formed with 16 altogether in whole framework.Screw (internal thread) 54 is formed in the central authorities in each spot-facing portion 52.
When protrusion 28 installs the foot 60 prepared as miscellaneous part, be used in upper 2 the spot-facing portions 52 formed of 1 installed surface 28A (or 28B) of protrusion 28 for 1 foot 60.During present embodiment, form two juts (holding section) 62 corresponding with 2 spot-facing portions 52 of protrusion 28 in foot 60 in advance.Further, the through hole 64 (especially with reference to figure 4) that the screw 54 being formed with axle center and protrusion 28 side in the central authorities of each jut 62 coincide.
Further, when protrusion 28 installs the hanging bolt 70 prepared as miscellaneous part, 1 spot-facing portion 52 (using the spot-facing portion 52 of other protrusions 28 when installing 1 pair of hanging bolt 70) is used for 1 hanging bolt 70.For this reason, hanging bolt 70 threaded portion 74 that there is the large-diameter portion (holding section) 72 corresponding with the spot-facing portion (engaged part) 52 of protrusion 28 and screw togather with screw 54.
In this execution mode, the reductor G1 linked with motor M1, adopts the reductor possessing the planetary gear reducing mechanism (omitting diagram) being called oscillating internal engagement type.This reductor G1 possesses the power shaft (omit and illustrate) linked with the not shown output shaft of motor M1, exports the rotation after slowing down from the output shaft 57 coaxial with this power shaft.
The profile L1 of reductor is greater than the profile L2 (being certainly greater than diagonal distance L4) of the protrusion 28 of the chassis body 14 of motor M1.In other words, protrusion 28 is converged in from perspective plane during end on observation reductor G1.And then the profile L1 of this reductor G1 is greater than the diagonal distance L4 of the apex portion of the tetragonal S of described imagination.Namely, the profile of reductor G1 is greater than the size of the outermost outline portion of fin 32, and the cooling air being configured to flow through along the fin 32 of chassis body 14 cooling fan 19 come blows to the load-side cover 16 linked with reductor G1, thus the shell 17 of this reductor G1 can also be cooled in the lump.
Then, the effect of this gearmotor GM1 is described.
If the power supply opening of motor M1 and become operating condition, then the cooling fan 19 linked with the output shaft of motor M1 rotates and cooling air is delivered to fin 32 side of chassis body 14.In the frame structure of present embodiment, be formed with protrusion 28 at 4 places, it is all configured between load-side base portion 22 and load reverse side base portion 24, even if in the cooling originally just not having also can expect hardly in the motor in the past of protrusion in this part.Especially, in this embodiment, because protrusion 28 is converged in the inner side of imaginary tetragonal S, so there is new problem hardly about the cooling between load-side base portion 22 and load reverse side base portion 24.
On the other hand, (avoid the position of through bolt) in the past and form protrusion each other at fin, so the flowing of cooling air is obviously obstructed and cooling effectiveness decline.But, in present embodiment, owing to not forming any protrusion each other at fin 32, so the flowing of cooling air can not be obstructed.Therefore, efficiency cooling higher than ever can be carried out as a result.And, along fin 32 flow through come cooling air due to blow to have than this fin 32 maximum profile (namely, the diagonal distance L4 of limit S1 ~ S4 of the tetragonal S of imagination) the load-side cover 16 that links of the shell 17 of reductor G1 of larger profile L1, so the shell 17 of this reductor G1 effectively can be cooled.
In addition, the advantage that cooling effectiveness is high is also can be interpreted as according to word " raising of cooling performance ", but obtain cooling performance as in the past just in sufficient situation, such as, by the height that reduces fin this advantage turned to more miniaturized, the lightweight of framework entirety etc.
On the other hand, when protrusion 28 installs foot 60, if make the jut of foot 60 (holding section) 62 be sticked in the spot-facing portion (engaged part) 52 of the installed surface 28A (or 28B) being about to the protrusion 28 installed, then automatically carry out the location of the installed surface 28A of the relative protrusion 28 of this foot 60, the axle center of the axle center of the screw 54 of protrusion 28 and the through hole 64 of foot 60 coincide.Therefore, bolt is screwed into screw 54 from the dorsal part of foot 60 through through hole 64 (omitting diagram), the installation of foot 60 can be completed.
And, when protrusion 28 installs hanging bolt 70, if make the threaded portion 74 of hanging bolt 70 be screwed together in the screw 54 of the central authorities in the spot-facing portion (engaged part) 52 of the installed surface 28A (or 28B) being about to the protrusion 28 installed, then the large-diameter portion 72 of hanging bolt 70 engages with the spot-facing portion 52 of installed surface 28A soon, thus can be mounted opposite face 28A and vertically and firmly install hanging bolt 70.
The holding section of spot-facing portion (engaged part) 52 or jut 62, large-diameter portion 72 etc. is machined, in advance so can carry out the high installation of accuracy.
The position of the space P1 ~ P4 of protrusion 28 near the summit of the tetragonal S of imagination is formed at 4 places, and, the spot-facing portion 52 that each protrusion 28 is formed along right angle orientation respectively is respectively formed with 2 meters 4, and no matter all can tackle with same structure (having interchangeability) for foot 60 or for hanging bolt 70, so such as reductor G1 or the position for terminal box 30, symmetrical foot 60 or hanging bolt 70 can be installed extremely neatly.
In addition, in above-mentioned execution mode, the projected direction of fin is given prominence in the mode that every two faces are orthogonal, but in the present invention, the projected direction of fin etc. are not particularly limited, such as can be outstanding to radiation direction.
Further, in above-mentioned execution mode, protrusion is converged in the imagination quadrangle that connects than the top of fin more in the inner part in the section rectangular with the axle of chassis body, even if but outstandingly a little also can obtain corresponding effect.
And, in above-mentioned execution mode, show and be suitable for example of the present invention at the gearmotor of motor and reductor integralization, but motor involved in the present invention is without the need to must to use with the state of reductor integralization, such as also can being suitable for when having and combinationally use with the reductor of the framework of motor independently shell.
And, in above-mentioned execution mode, form 4 protrusions and form multiple engaged part for installing miscellaneous part or bolt hole at each protrusion, but in the present invention, the quantity of protrusion, the quantity of engaged part formed, the quantity of bolt hole are all not particularly limited.Further, the miscellaneous part of multiple kind can be installed at the protrusion of same structure, but in the present invention, the miscellaneous part also can installed by each forms protrusion itself, engaged part or bolt hole respectively.Also be not limited to said structure about engaged part and the shape of the holding section of miscellaneous part side that engages with this engaged part, such as, also convex with recessed relation can be turned around and the shape of engaged part is also decided to be round shape without the need to one.
In addition, in the present invention, at protrusion also without the need to this engaged part must be formed.Such as (without engaged part) only can form bolt hole, the stage that also can occur at generation installation requirement, aft-loaded airfoil engaged part or bolt hole.This is also identical for the holding section corresponding to miscellaneous part.
