Description
Technical field
The utility model relates to planetary speed reducer with small tooth number difference, relates in particular to a kind of circular mobile tooth planetary reducer.
Background technique
In existing planetary speed reducer with small tooth number difference, have two hang-ups: 1, rotary arm bearing makes bearing life shorter because of its diameter of limitation that is subjected to the space is little; 2, the bearing pin of output mechanism influences its insufficient strength because of diameter is less.The most basic solution is to use high-quality good material, but this can cause its cost to improve greatly, the structure and the kind of drive that change retarder are existing feasible methods, as the sleeve planetary speed reducer with small tooth number difference, though on its planet wheel, cancelled a circle pin-and-hole, solved the problem of pivot pin insufficient strength, but do not made the rotary arm bearing increasing diameter what add, bearing life is still shorter; Another kind is an osculating circle oscillating tooth planetary reducer, though the rotary arm bearing diameter is increased, the thin walled cylinder intensity of output mechanism is subjected to bigger restriction, is not suitable for high-power transmission, and cylinder is located at output shaft simultaneously, has many square hole difficulty of processing very big again.Therefore, these two kinds of retarders all fail to solve simultaneously above-mentioned two hang-ups.
Summary of the invention
For overcoming one's shortcomings, solve above-mentioned two hang-ups simultaneously, the purpose of this utility model is to provide a kind of rotary arm bearing diameter bigger, and the also bigger circular mobile tooth planetary reducer of bearing pin distribution circle diameter of output mechanism, this retarder bearing life-span is longer, and output mechanism intensity obviously improves.
The utility model is realized as follows for achieving the above object: it is made up of input shaft, planet wheel and pin-and-hole formula output mechanism, be provided with eccentric bushing, rotary arm bearing and inner ring roller, circular mobile tooth and the fixing ring gear of input shaft periphery in the planet wheel, described circular mobile tooth is the cylindrical roller oscillating tooth, rotary arm bearing outer ring directly empty cover inner ring roller, the cylindrical roller oscillating tooth is contained in the outer ring of inner ring roller, and cylindrical roller oscillating tooth outer ring is meshed with the flank profil of the ring gear of fixing again simultaneously; Output mechanism comprises output shaft and the bearing pin and the pin-and-hole of band pin dish, and pin-and-hole is located on the pin dish, and its bearing pin is replaced by the cylindrical roller of circular mobile tooth, and an end of cylindrical roller inserts in the pin-and-hole.
The utility model compared with prior art, be that bearing pin with original cylinder oscillating tooth pin-and-hole formula output mechanism unites two into one, and the bearing pin of pin-and-hole formula output mechanism and the assembling and the drive connection of pin-and-hole put upside down mutually, make the space of rotary arm bearing increase, diameter increases, and bearing pin distribution circle diameter also obviously increases, therefore, improve the life-span of rotary arm bearing and the intensity of bearing pin, can realize high-power transmission.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Referring to Fig. 1, Fig. 2: this retarder is made up of input shaft, planet wheel and pin-and-hole formula output mechanism, and input shaft 1 periphery in the planet wheel is provided with eccentric bushing 2, rotary arm bearing 3 and inner ring roller 4, circular mobile tooth 5 and fixing ring gear 6; Its circular mobile tooth 5 is the cylindrical roller oscillating tooth, directly empty cover inner ring roller 4 on rotary arm bearing 3 outer rings, and inner ring roller 4 outer rings are cylindrical roller oscillating tooth 5, cylindrical roller oscillating tooth 5 is meshed with the flank profil of the ring gear of fixing 6 again; Output mechanism comprises output shaft 9 and the bearing pin and the pin-and-hole of band pin dish 11, and its bearing pin is replaced by the cylindrical roller of circular mobile tooth 5, and an end of its cylindrical roller inserts in the pin-and-hole.Equilibrium block 7 is housed on the input shaft 1, all carrying of the effect of all carrying has been housed on the cylindrical roller oscillating tooth 5 of replacement bearing pin has encircled 8, support 10 is fixed in the retarder periphery.In the existing retarder, bearing pin is located on the pin dish 11, and planet wheel is provided with pin-and-hole, and the bearing pin of pin-and-hole formula output mechanism of the present utility model is replaced by cylindrical roller oscillating tooth 5, it is united two into one and makes bearing pin and the assembling of pin-and-hole and drive connection are put upside down mutually.The diameter of rotary arm bearing is increased greatly.
Above-mentioned cylindrical roller oscillating tooth 5 is meshed with the flank profil of the ring gear of fixing 6, belongs to the interior engagement of concavo-convex contact, and the cylindrical roller oscillating tooth 5 here unites two into one with the bearing pin of pin-and-hole formula output mechanism.The tooth number Z of ring gear 6
2With roller oscillating tooth 5 tooth number Z
1Differing is one, and its velocity ratio is Z
1Value.Nie He the number of teeth is Z in theory simultaneously
1Half, be multiple tooth engagement.Two Gear center O
2And O
1Be eccentric, input shaft 1 and output shaft 9 be concentric (be O
2).
When input shaft 1 rotation, eccentric bushing 2 on it drives rotary arm bearing 3 rotations, make the inner ring roller 4 and the cylindrical roller oscillating tooth 5 of the overhead cover in rotary arm bearing 3 outer rings do eccentric motion and side set motion, make cylindrical roller oscillating tooth 5 both do revolution at a high speed, do the planetary motion of low speed rotation again.The other end of the rotation of cylindrical roller oscillating tooth 5 by its cylindrical roller be as bearing pin, is in contact with one another all the time and rotates with pin-and-hole on the output shaft 9 pin dishes 11, and the low speed, the dead axle that the planetary motion of cylindrical roller oscillating tooth 5 are become output shaft 9 rotate, and slows down realizing.
The effect that 4 pairs of cylindrical roller oscillating tooths 5 of inner ring roller have isolation, location and all carry makes driving component have rollerization and rollingization.This two circle roller structures are compared with similar individual pen roller structure, realized full rolling, so transmission efficiency are higher.
The flank profil of ring gear 6 can adopt the short width of cloth of conjugate curve or the recessed flank profil of interior circular arc of prolate hypocycloid and very approximate conjugation to substitute, and adopts general grinding machine to carry out the grinding of hard tooth, and to improve the contact strength of the flank of tooth, its contact strength of tooth surface improves greatly.
Also can be referring to the inner ring roller 4 among Fig. 3,4: Fig. 1,2 embodiments by the oscillating tooth seat ring 4 ' replacement of band circle-arc tooth nest, cylindrical roller oscillating tooth 5 is contained in its circle-arc tooth nest.
