Embodiment
Referring to accompanying drawing, an example of embodiments of the present invention is elaborated.
As shown in background technique, simple planetary decelerator series involved in the present invention is made up of the different simple planetary speed reducer of reduction speed ratio.
In the 1st mode of execution of the present invention, utilize Fig. 1, Fig. 2 to describe an example of the 1st secondary series in simple planetary decelerator series.In the simple planetary speed reducer 100 (200) of the 1st secondary series, on the radial direction of wheel support body 124 (224), possess supporting this takes turns the bearing (main bearing) 134 of support body 124 (224) in the outside of the bearing position of planet pin 120 (220), 138 (234, 238), this bearing 134, 138 (234, 238) inner ring and this are taken turns support body 124 (224) and are integrally formed, and be formed with internal gear 122 (222) (as modified embodiment of the present embodiment at shell 142 (242), also can form internal gear in shell split.)。And, in the 1st secondary series, its feature is, shell 142 and shell 242 become shared, and the bearing position of planet pin 120 (220) in sun gear 114 (214), planetary pinion 116 (216) and wheel support body 124 (224) changes according to described reduction speed ratio.
At this, the simple planetary speed reducer 100,200 shown in Fig. 1, Fig. 2, due to only mechanically reduction speed ratio be respectively approximately 1/4 and approximately 1/10 and different, so the simple planetary speed reducer 100 of Fig. 1 is elaborated.
Simple planetary speed reducer 100, possess sun gear 114, be engaged in the internal gear 122 of engagement in 116 of planetary pinion 116, this planetary pinions of this sun gear 114, rotatably mounted this planetary pinion 116 planet pin 120, support this planet pin 120 and the wheel support body 124 of synchronizeing with the revolution composition of described planetary pinion 116.In addition, shell 142 is by the rotatably mounted support body 124 of taking turns of bearing 134,138.
Described sun gear 114 is pressed in input shaft 110.Input shaft 110 has the patchhole 110A that inserts not shown motor reel, and motor reel is inserted in patchhole 110A and in conjunction with input shaft 110 and motor reel.In sun gear 114, for example, be provided with helical gear (can be also spur wheel) and be meshed with planetary pinion 116.
More than 116 of described planetary pinions are disposed at the periphery of sun gear 114, revolution in the time of sun gear 114 rotation.Planetary pinion 116 is supported on planet pin 120 by planetary bearing 118.Planetary bearing 118 is needle roller to be divided into 2 and with the bearing of total roller state configuration on axial O.Therefore,, in the time that sun gear 114 and planetary pinion 116 are meshed, can reduce an end in contact of needle roller.In addition, needle roller is owing to using under the total roller state that there is no retainer, so can be by large transmission of torque to planet pin 120.
Described internal gear 122 comprises the toothed region engaging with planetary pinion 116 and is integrally formed at shell 142.
Described planet pin 120 is supported on wheel support body 124.Planet pin 120 forms with 124 splits of wheel support body.Therefore, planet pin 120 can be processed with high surface accuracy (shape or roughness etc.), thus can make planetary bearing 118 long lifetimes, and can reduce the torque loss of planetary pinion 116.
The described support body 124 of taking turns becomes the structure that links wheel carrier phosphor bodies 126 and wheel support body plate 128.Wheel carrier phosphor bodies 126 links by bolt 130 or is fixed on takes turns support body plate 128.Therefore, wheel support body 124 is synchronizeed with the revolution composition of planetary pinion 116, with planet pin 120 these revolution compositions of taking-up and rotate.In addition, wheel support body 124 be formed be pressed into planet pin 120 be pressed into hole 126B, 128B.Change according to reduction speed ratio this formation position that is pressed into hole 126B, 128B.Be integrally formed with the output shaft 132 of flange shape in a side contrary to planetary pinion of wheel carrier phosphor bodies 126.Be provided with multiple bolts hole at its end face, carry out the driven shaft of connecting object machinery by linking not shown bolt at the bolt hole of its output shaft 132.
Described bearing 134,138 be disposed at wheel support body 124 radial direction outside and as main bearing, and the rotatably mounted support body 124 of taking turns.Bearing 134,138 is angular contact ball bearing, possesses respectively ball 135,139 and outer ring 136,140, and their inner ring is integrally formed with wheel support body 124.Therefore, when split arranges with wheel support body with inner ring, compare, can guarantee the part 126A of the wheel support body 124 between planet pin 120 and bearing 134,138, the wall thickness of 128A without the profile that increases shell 142, can also widen the diameter of planet pin 120 simultaneously.
And bearing 134,138 clips internal gear 122 and is axially configuring on O.And bearing 134,138 configures with back-to-back combination.Therefore, can support high radial load and axial load.In addition, outer ring 136,140 and the shell 142 of bearing 134,138 become Split type structure.Therefore,, even bearing 134,138 differences, shell 142 also can be directly to share use in the 1st secondary series.The inner race track face of bearing 134,138 is formed at the outer circumferential face 127,129 of wheel support body 124.
In addition, the latch part E that the periphery 142A of shell 142 becomes benchmark when installing with the not shown link shell tabling of object machinery plays a role.On shell 142, on axial O, link stage casing cover 144 and leading portion cover 146 with bolt 148.Between stage casing cover 144 and input shaft 110, be provided with oil sealing 152.And, disposing bearing 112 in the inner side of stage casing cover 144, stage casing cover 144 is by the rotatably mounted input shaft 110 of bearing 112.Bearing 112 by stage casing cover 144 and leading portion cover 146 on axial O, be placed into and fix.In addition, the mark 150 of Fig. 1 is to be disposed at the oil sealing between shell 142 and output shaft 132 in order to seal the inside and outside of simple planetary speed reducer 100.
The effect of simple planetary speed reducer 100 then, is described.
For example, thus the rotation that utilizes not shown motor is rotated sun gear 114 by input shaft 110.If like this, sun gear 114 and planetary pinion 116 are meshed and when planetary pinion 116 rotation, revolve round the sun around sun gear 114.Now, with the interior internal gear engaging 122 of planetary pinion 116 in stationary state, so trailing wheel support body 124 takes out the revolution composition of planetary pinion 116.Wheel support body 124 makes the driven shaft rotation of the object machinery that is installed on output shaft 132.
At this, the simple planetary speed reducer 200 shown in Fig. 2 also moves in the same manner with the simple planetary speed reducer 100 of Fig. 1.But the reduction speed ratio of simple planetary speed reducer 100 is approximately 1/4, with respect to this, the reduction speed ratio of simple planetary speed reducer 200 becomes approximately 1/10.Therefore, compared with the number of teeth of sun gear 114, the number of teeth of sun gear 214 is less, and the number of teeth of planetary pinion 216 is more (from magnitude relationship compared with the number of teeth of planetary pinion 116, sun gear 214 is less compared with sun gear 114, and planetary pinion 216 is larger compared with planetary pinion 116).In the 1st secondary series, shell 142,242 is made as shared, so link radius R 1, the R2 unequal (R1 > R2) of each circle (pitch circle) of the central position of planet pin 120,220, wheel support body 124 is also different from wheel support body 224.Particularly, planet pin 120,220 formation position (being pressed into the pitch diameter in the hole) difference that is pressed into hole 126B (128B), 226B (228B) separately.That is, according to reduction speed ratio, for example reduction speed ratio changes to approximately 1/10 o'clock from approximately 1/4, and the sun gear 114 of simple planetary speed reducer 100, planetary pinion 116, wheel support body 124 change to respectively sun gear 214, planetary pinion 216, wheel support body 224.In addition, in the present embodiment, although that planet pin 120,220 also becomes is shared, as modified embodiment of the present embodiment, planet pin also can be non-sharing.
Present embodiment is following mode: on the radial direction of wheel support body 124 (224), in the arranged outside bearing 134,138 (234,238) of the bearing position of planet pin 120 (220), be integrally formed the inner ring of bearing 134,138,234,238 with wheel support body 124,224.Therefore, can increase to greatest extent bearing 134,138 (234,238), even the low reduction speed ratio that is for example approximately 1/4 at simple planetary speed reducer 100, also can guarantee the part 126A of the wheel support body 124 that supports planet pin 120, the wall thickness of 128A, can also widen planet pin 120 diameters simultaneously.Therefore, finally can increase the planetary bearing 118 being disposed between planetary pinion 116 and planet pin 120.Therefore, without making the maximization of speed reducer own can improve output torque.Especially in the present embodiment, due to planet pin 120 (220) and wheel support body 124 (224) are made as to split, so can make planetary bearing 118 long lifetimes.Meanwhile, the inner ring of bearing 134,138 (234,238) is not made as to separate part, so can reduce part number of packages.And, as the 1st secondary series, make to be integrally formed shell 142 (242) sharings of internal gear 122 (222), so can seek the minimizing of the total part number of packages in series, total minimizing of quantity in stock and the minimizing of cost of parts.
And in present embodiment, bearing 134,138 (234,238) clips internal gear 122 (222) and is axially being used 2 on O, and bearing 134,138 (234,238) becomes back-to-back combination.Therefore, can support high radial load and axial load.
And, present embodiment is because shell 142 (242) is for sharing, become same shape so be connected in the part of object machinery and be the periphery 142A of shell 142, so according to the object required output torque of machinery or rotating speed, can easily carry out the exchange in simple planetary decelerator series, when exchange, the periphery 142A of shell 142 plays a role as latch part E, can easily carry out thus axle center alignment.
Therefore, according to present embodiment, when making internal gear 122,222 sharing, without making the maximization of speed reducer own can improve output torque.
Then,, in the 2nd mode of execution of the present invention, utilize Fig. 1, Fig. 3 to describe an example of the 2nd secondary series in simple planetary decelerator series.
In present embodiment, simple planetary speed reducer 100 and simple planetary speed reducer 300 form the 2nd secondary series.; in the 2nd secondary series; simple planetary speed reducer 100 (300) is on the radial direction of wheel support body 124 (324); possess supporting this takes turns the bearing 134,138 (334,338) of support body 124 (324) in the outside of the bearing position of planet pin 120 (320); the inner ring of this bearing 134,138 (334,338) and this are taken turns support body 124 (324) and are integrally formed; and on shell 142 (342), be formed with internal gear 122 (322) (as modified embodiment of the present embodiment, can shell split form internal gear).And in the 2nd secondary series, its feature is, shell 142 (342) changes according to reduction speed ratio, and the bearing position of planet pin 120,320 is made as shared, takes turns thus support body 124 and wheel support body 324 becomes shared.
At this, the simple planetary speed reducer 100,300 shown in Fig. 1, Fig. 3 only in function reduction speed ratio be respectively approximately 1/4 and approximately 1/3 and different.Therefore, omit about the constitutive requirements of simple planetary speed reducer 100,300 and the explanation of effect.
The reduction speed ratio of simple planetary speed reducer 300 is approximately 1/3, is the low reduction speed ratio lower than the reduction speed ratio of simple planetary speed reducer 100.At this, shell 342 and shell 142 are made as while sharing, the radius R 3 of pitch circle becomes the radius R 1 that is more greater than pitch circle, and the wall thickness of part of the wheel support body between planet pin and main bearing and the danger of the thickness of planet pin cannot be fully guaranteed in appearance.Therefore, the wall thickness dividing for the wheel carrier body of fully guaranteeing between planet pin and main bearing and the thickness of planet pin, simple planetary speed reducer 300 saves radius of a circle with simple planetary speed reducer 100 and is set as identical (R1=R3).Thus, the bearing position of planet pin 120,320 becomes shared, can wheel support body 324 and wheel support body 124 is made as shared.In addition, in the 2nd secondary series, planet pin 120,320 becomes shared.
; the 2nd secondary series makes to have the simple planetary speed reducer 100 (300) of the feature that can increase output torque identical with the 1st secondary series; sharing wheel support body 124 and wheel support body 324; and internal gear 122 (322) not reduces thus part number of packages and can realize cost degradation.
Meanwhile, although shell 142 (342) does not share, joint radius of a circle is made as to shared (R1=R3), so can the profile of shell 342 is made as identical with the profile of shell 142.; the part that is connected in object machinery due to shell 342 is that periphery 342A and the periphery 142A of shell 342 is same shape; so easily cross the exchange of the simple planetary speed reducer in the 2nd secondary serial series according to the required reduction speed ratio of object machinery; when exchange, the periphery 342A of shell 342 plays a role as latch part E, can easily carry out thus axle center alignment.,, for identical object machinery, the 2nd secondary series has the interchangeability that is connected with the 1st secondary series.
And, bearing 134,138 and bearing 334,338 can be made as identically, and various piece 342B, the 342C of the shell 342 corresponding with various piece 142B, the 142C of the shell 142 of block bearing 134,138 can be made as to condition of equivalent thickness.Therefore,, even if shell 142 (342) does not share, also can guarantee equal output torque to the simple planetary speed reducer of crossing in the 2nd secondary serial series.
And, by forming simple planetary decelerator series by the 1st, the 2nd secondary series, can make up than the reduction speed ratio with reduction speed ratio wider scope of the 1st secondary series only, and with respect to identical object machinery, can make the 1st, the 2nd secondary series seamlessly corresponding according to reduction speed ratio.
Then,, in the 3rd mode of execution of the present invention, utilize Fig. 4, Fig. 5 to describe an other example of the 1st secondary series in simple planetary decelerator series.
Present embodiment is the mode that the angular contact ball bearing of each bearing 134,138 (234,238) of the simple planetary speed reducer of the 1st mode of execution 100 (200) is changed to angular contact roller bearing.Therefore, except the roller of bearing 434,438 (534,538) and outer ring 436,440 (536,540) and (being formed with inner race track face) wheel support body 424 (524) differences that are integrally formed inner ring corresponding to bearing 434,438 (534,538), identical with the 1st mode of execution, so add the rear identical mark of 2 bit digital, description thereof is omitted.
In the present embodiment, main bearing is used to roller, and do not use ball, so can strengthen the resistance to load of main bearing.Therefore,, compared with the 1st secondary series of the 1st mode of execution of low torque loss property excellence, can make simple planetary speed reducer 400,500 further strengthen resistance to load, and can improve durability.At this, the outer ring 436,440 (536,540) of bearing 434,438 (534,538) becomes split with shell 442 (542), so when can making shell 442 (542) shared, easily change the kind of bearing.,, in the 1st secondary series of simple planetary speed reducer, can adopt angular contact ball bearing and angular contact roller bearing to be used as main bearing.Now, become Split type structure by outer ring and the shell of main bearing, except main bearing and the wheel support body that be integrally formed inner ring corresponding with the kind of main bearing, without change, can provide simple planetary speed reducer according to the requirement of output torque or durability.In addition, even present embodiment is applied in the 2nd secondary series, if the kind of main bearing is identical, also wheel support body can be made as sharedly, and can obtain corresponding effect.

And, in the above-described embodiment, be used in combination 2 bearings with back-to-back, but the present invention may not necessarily be limited to this, can be also the situation that uses 1 bearing.For example, also can only configure 1 crossed roller bearing and use, its outer ring and shell are made as to Split type structure and form.Now, the axial load that also can bear twocouese on the axial O of the driven shaft of object machinery, and can obtain the same action effect when using 2 bearings, and then realize the shortening to axial O of simple planetary speed reducer.
And even while using 2 bearings, also can use tapered roller bearing, its combination is also not limited to the back side, can be positive combination or combination side by side.
And, in the above-described embodiment, although planet pin and wheel support body are made as to split, the invention is not restricted to this.For example, also planet pin can be integrally formed to wheel support body.In the 1st secondary series at this moment, prepare according to reduction speed ratio and the different wheel support body in the formation position of planet pin.In the 2nd secondary series, can be by the wheel support body that is integrally formed planet pin directly to share use.
