Embodiment
Following with reference 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 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 that one example of the 1st secondary series in the simple planetary decelerator series is described.In the simple planetary speed reducer 100 (200) of the 1st secondary series, on the radial direction of wheel support body 124 (224), this takes turns the bearing (main bearing) 134,138 (234,238) of support body 124 (224) to possess supporting in the outside of the bearing position of planet pin 120 (220), it is integrally formed that the inner ring of this bearing 134,138 (234,238) and this are taken turns support body 124 (224), and be formed with internal gear 122 (222) at shell 142 (242) and (, also can form internal gear in the shell split as modified embodiment of the present embodiment.)。And, in the 1st secondary series, its characteristics are that shell 142 and shell 242 become shared, and sun gear 114 (214), planetary pinion 116 (216), and wheel support body 124 (224) in the bearing position of planet pin 120 (220) change according to described reduction speed ratio.
At this, the simple planetary speed reducer 100,200 shown in Fig. 1, Fig. 2 since only mechanically reduction speed ratio be respectively about 1/4 with about 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 synchronous with the revolution composition of described planetary pinion 116.In addition, shell 142 is by bearing 134, the 138 rotatably mounted support bodys 124 of taking turns.
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 (also can be spur wheel) and be meshed with planetary pinion 116.
More than 116 peripheries that are disposed at sun gear 114 of described planetary pinion, revolution in the time of sun gear 114 rotations.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, when sun gear 114 and planetary pinion 116 are meshed, can reduce an end in contact of needle roller.In addition, needle roller is not owing to use under total roller state of retainer having, so can be with big transmission of torque to planet pin 120.
Described internal gear 122 comprises the toothed region that meshes 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 or is fixed in by bolt 130 takes turns support body plate 128.Therefore, wheel support body 124 is synchronous with the revolution composition of planetary pinion 116, takes out these revolution compositions and rotates with planet pin 120.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 an opposite side with planetary pinion of wheel carrier phosphor bodies 126.Be provided with a plurality of bolts hole at its end face, link the driven shaft that not shown bolt comes connecting object machinery by bolt hole at its output shaft 132.
Described bearing 134,138 be disposed at wheel support body 124 the radial direction outside and as main bearing, and the rotatably mounted support body 124 of taking turns.Bearing 134,138 is an angular contact ball bearing, possesses ball 135,139 and outer ring 136,140 respectively, and their inner ring is integrally formed with wheel support body 124.Therefore, compare when the support body split is provided with wheel with inner ring, the profile that need not to increase shell 142 can be guaranteed the part 126A of the wheel support body 124 between planet pin 120 and the bearing 134,138, the wall thickness of 128A, and the while can also be widened the diameter of planet pin 120.
And bearing 134,138 clips internal gear 122 and is axially disposing on the O.And bearing 134,138 disposes with back-to-back combination.Therefore, can support high radial load and axial load.In addition, the outer ring 136,140 and the shell 142 of bearing 134,138 become the branch body structure.Therefore, even bearing 134,138 differences, shell 142 also can be directly with shared 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.
The latch part E that becomes benchmark when in addition, the periphery 142A of shell 142 conduct is installed with the not shown binding shell tabling of object machinery plays a role.On shell 142, axially linking stage casing cover 144 and leading portion cover 146 with bolt 148 on the O.Be provided with oil sealing 152 between stage casing cover 144 and the input shaft 110.And, disposing bearing 112 in the inboard of stage casing cover 144, stage casing cover 144 is by bearing 112 rotatably mounted input shafts 110.Bearing 112 is placed on axial O by stage casing cover 144 and leading portion cover 146 and fixes.In addition, the mark 150 of Fig. 1 is the oil sealings that are disposed in order to seal the inside and outside of simple planetary speed reducer 100 between shell 142 and the output shaft 132.
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 planetary pinion 116 rotations the time, around sun gear 114 revolution.At this moment, be in stationary state, so trailing wheel support body 124 takes out the revolution composition of planetary pinions 116 with the internal gear 122 that meshes in the 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, simple planetary speed reducer 200 shown in Figure 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 about 1/4, and with respect to this, the reduction speed ratio of simple planetary speed reducer 200 becomes about 1/10.Therefore, compare 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 comparing planetary pinion 216 with the number of teeth of planetary pinion 116 is more (from magnitude relationship, to compare sun gear 214 less with sun gear 114, and to compare planetary pinion 216 bigger with planetary pinion 116).In the 1st secondary series, shell 142,242 is made as shared, unequal (R1＞R2), wheel support body 124 is also different with wheel support body 224 so link radius R 1, the R2 of each circle (pitch circle) of central position of planet pin 120,220.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 changed to about 1/10 o'clock from about 1/4, and the sun gear 114 of simple planetary speed reducer 100, planetary pinion 116, wheel support body 124 change to sun gear 214, planetary pinion 216, wheel support body 224 respectively.In addition, in the present embodiment, though that planet pin 120,220 also becomes is shared, as modified embodiment of the present embodiment, the planet pin also can be non-shared.
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), with the inner ring of wheel support body 124,224 integrally formed bearings 134,138,234,238.Therefore, can increase bearing 134,138 (234,238) to greatest extent, even be under the situation of about 1/4 low reduction speed ratio for example at simple planetary speed reducer 100, also can guarantee to support the part 126A of the wheel support body 124 of planet pin 120, the wall thickness of 128A, can also widen planet pin 120 diameters simultaneously.Therefore, finally can increase the planetary bearing 118 that is disposed between planetary pinion 116 and the planet pin 120.Therefore, need not to make the maximization of speed reducer own can improve the output torque.Especially in the present embodiment, because planet pin 120 (220) and wheel support body 124 (224) are made as split, so can make planetary bearing 118 long lifetimes.Simultaneously, the inner ring with bearing 134,138 (234,238) is not made as separate part, so can reduce the part number of packages.And, as the 1st secondary series, make shell 142 (242) sharings of integrally formed internal gear 122 (222), so can seek the minimizing of the total part number of packages in the series, the minimizing of total quantity in stock and the minimizing of cost of parts.
And in the present embodiment, bearing 134,138 (234,238) clips internal gear 122 (222) and axially is being used 2 on the 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 shared, so being connected in the part of object machinery and being the periphery 142A of shell 142 becomes identical shaped, so according to object required output torque of machinery or rotating speed, can carry out the exchange in the simple planetary decelerator series easily, the periphery 142A of shell 142 plays a role as latch part E during exchange, can carry out the axle center alignment thus easily.
Therefore, according to present embodiment, when making internal gear 122,222 sharings, need not to make the maximization of speed reducer own can improve the output torque.
Then, in the 2nd mode of execution of the present invention, utilize Fig. 1, Fig. 3 that one example of the 2nd secondary series in the simple planetary decelerator series is described.
In the present embodiment, simple planetary speed reducer 100 and simple planetary speed reducer 300 constitute the 2nd secondary series.Promptly, in the 2nd secondary series, simple planetary speed reducer 100 (300) is on the radial direction of wheel support body 124 (324), this takes turns the bearing 134,138 (334,338) of support body 124 (324) to possess supporting in the outside of the bearing position of planet pin 120 (320), it is integrally formed that the inner ring of this bearing 134,138 (334,338) and this are taken turns support body 124 (324), and on shell 142 (342), be formed with internal gear 122 (322) (, can form internal gear) in the shell split as modified embodiment of the present embodiment.And in the 2nd secondary series, its characteristics are, shell 142 (342) changes according to reduction speed ratio, and the bearing position of planet pin 120,320 are made as shared, take turns support body 124 thus and wheel support body 324 becomes shared.
At this, the simple planetary speed reducer 100,300 shown in Fig. 1, Fig. 3 only on function reduction speed ratio be respectively about 1/4 with about 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 about 1/3, is the low reduction speed ratio that is lower than the reduction speed ratio of simple planetary speed reducer 100.At this, shell 342 and shell 142 are made as when shared, the radius R 3 of pitch circle becomes more greater than the radius R 1 of pitch circle, and the danger of the thickness of the wall thickness of part of the wheel support body between planet pin and the main bearing and planet pin can't be fully guaranteed in appearance.Therefore, for the wall thickness of fully guaranteeing the wheel carrier body portion between planet pin and the main bearing and the thickness of planet pin, simple planetary speed reducer 300 is set as identical (R1=R3) with the radius of simple planetary speed reducer 100 pitch circles.Thus, the bearing position of planet pin 120,320 becomes shared, can be made as wheel support body 324 and wheel support body 124 shared.In addition, in the 2nd secondary series, planet pin 120,320 becomes shared.
Promptly, the 2nd secondary series makes the simple planetary speed reducer 100 (300) with feature that can increase output torque identical with the 1st secondary series, sharing wheel support body 124 and wheel support body 324, and be not internal gear 122 (322) reduce the part number of packages thus and can realize cost degradation.
Simultaneously, though shell 142 (342) is not shared, the radius of pitch circle is made as shared (R1=R3), so can be made as identical with the profile of shell 142 profile of shell 342.Promptly, because the part that shell 342 is connected in object machinery is that the periphery 342A and the periphery 142A of shell 342 is identical shaped, so cross the exchange of the simple planetary speed reducer in the serial series of the 2nd pair easily according to the required reduction speed ratio of object machinery, the periphery 342A of shell 342 plays a role as latch part E during exchange, can carry out the axle center alignment thus easily.That is, 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 condition of equivalent thickness.Therefore, even shell 142 (342) is not shared, also can guarantee equal output torque to the simple planetary speed reducer in the series of crossing the 2nd secondary series.
And, by constituting the simple planetary decelerator series by the 1st, the 2nd secondary series, can remedy than only with the reduction speed ratio of reduction speed ratio wider scope of the 1st secondary series, and, can make the 1st, the 2nd secondary series seamlessly corresponding according to reduction speed ratio with respect to identical object machinery.
Then, in the 3rd mode of execution of the present invention, utilize Fig. 4, Fig. 5 that an other example of the 1st secondary series in the simple planetary decelerator series is described.
Present embodiment is the mode that the angular contact ball bearing of each bearing 134,138 (234,238) of the simple planetary speed reducer 100 (200) of the 1st mode of execution 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 corresponding to (being formed with the inner race track face) wheel support body 424 (524) of the integrally formed inner ring of bearing 434,438 (534,538) different, identical with the 1st mode of execution, omit explanation so add the back identical mark of 2 bit digital.
In the present embodiment, main bearing is used roller, and do not use ball, so can strengthen the anti-load of main bearing.Therefore, lose the 1st secondary series of the 1st mode of execution of excellent with low torque and compare, can make simple planetary speed reducer 400,500 further strengthen anti-load, and can improve durability.At this, the outer ring 436,440 (536,540) of bearing 434,438 (534,538) and shell 442 (542) become split, so when can make shell 442 (542) shared, change the kind of bearing easily.That is, 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.At this moment, outer ring and shell by main bearing become the branch body structure, need not change except the wheel support body of main bearing and the integrally formed inner ring corresponding with the kind of main bearing, can provide the simple planetary speed reducer according to output torque or durability requirement.In addition,,, also the wheel support body can be made as sharedly, and can obtain corresponding effects if the kind of main bearing is identical even present embodiment is applied in the 2nd secondary series.
