Abstract
The utility model relates to a speed reducing device with a planetary gear and small teeth difference, belonging to a speed reducers with planetary gears and small teeth difference. The utility model is characterized in that an eccentric shaft and another eccentric which are unequal are arranged in the same plane, and passes through a bearing and another bearing; the eccentric shafts are respectively connected with the planetary gear; two eccentricity respectively ensures the planetary transmission with the small teeth difference of a ring gear of a planetary gear pair with small teeth difference, between the planetary gear and the ring gear, and the planetary gear; the ring gear is fixed with a housing; internal tooth difference is fixed with an output shaft; a duplicate gear is composed of the two planetary gears; the number difference of the teeth of the ring gear of the planetary gear pair, the planetary gear and the ring gear of the planetary gear pair, and the planetary gear is not equal.
Description
The utility model belongs to a kind of planet gear speed reducer with small tooth difference, is specially a kind of small teeth number difference planet gear speed reducer.
Existing existing planet gear speed reducer with small tooth difference all has complicated power take-off mechanism, and ratio coverage is little.
The purpose of this utility model is the speed ratio that can obtain zero-hundreds of thousands by the compound transmission that two-stage fewer differential teeth planetary internal gear is paid, and is simple in structure, reduced rate of fault, improves working life.
The purpose of this utility model is achieved in that it is made up of output shaft (1), eccentric shaft (2), bearing (3), planetary pinion (4), (7), ring gear (5), (6), bearing (8), eccentric shaft (9), equilibrium block (10), output shaft (11) and housing etc.It is characterized in that: in same plane, have two unequal eccentric shafts (2) and link to each other with eccentric shaft (9).And by bearing (3), bearing (8), eccentric shaft (2), (9) link to each other with planetary pinion (4), (7) respectively, two throw of eccentric guarantee that respectively small teeth number difference planet gear is paid ring gear (5), planetary pinion (4) lacks the transmission of tooth difference with the planet of ring gear, planetary pinion (7), ring gear (5) is fixed with housing, internal tooth poor (6) is fixing with output shaft (11), duplicate gear is formed in two planetary pinions (4), (7), and planetary pinion is paid ring gear (5), planetary pinion (4) is unequal with the number of teeth difference that planetary pinion is paid ring gear (6), planetary pinion (7).Advantage of the present utility model is: compares with present existing retarder, and in light weight, speed ratio is broad, speed ratio is big more broad more.Compare with JZQ series gear reducer, owing to adopt the internal gear transmission, onesize gear, driving torque can improve more than two times, and volume has only about 1/3.Subtract main device with worm and gear and compare, mechanical efficiency of the present utility model can reach more than 90%.On international market since the eighties, most widely used cycloidal-pin wheel retarder is compared, the planet wheel of cycloidal-pin wheel retarder adopts the symmetric double escapement, bearing pin output, planet wheel bearing are restricted, and the utility model does not have the bearing pin output mechanism, and the bearing on the planetary pinion can select the big bearing of ability to bear, cycloid wheel, pinwheel seat, output shaft pin-and-hole required precision height, need to use special purpose machine tool, and the utility model can just can be made with general purpose machine tool, reduces cost.When cycloidal-pin wheel retarder velocity ratio is big, need more than the two-stage, just can obtain several ten thousand even hundreds of thousands large speed ratio very and planet gear speed reducer with small tooth difference of the present utility model only need change speed ratio difference that two pairs of fewer differential teeth planetary internal gears pay.
Fig. 1 is the utility model structural principle schematic representation.
1,11-output shaft, 2,9-eccentric shaft, 3,8-bearing, 4,7-planetary pinion, 5,6-ring gear, 10-equilibrium block.
Below in conjunction with accompanying drawing in detail the utility model most preferred embodiment is described in detail: it is by output shaft (1), eccentric shaft (2), bearing (3), planetary pinion (4), (7), ring gear (5), (6), bearing (8), eccentric shaft (9), equilibrium block (10), compositions such as output shaft (11) and housing, in same plane, have two unequal eccentric shafts (2) and eccentric shaft (9), and by bearing (3), bearing (8), eccentric shaft (2), (9) respectively with planetary pinion (4), (7) link to each other, two throw of eccentric guarantee that respectively small teeth number difference planet gear pays ring gear (5), planetary pinion (4) and ring gear (6), the few tooth difference transmission of the planet of planetary pinion (7), ring gear (5) is fixed with housing, internal tooth poor (6) is fixing with output shaft (11), two planetary pinions (4), (7) form duplicate gear, planetary pinion is paid ring gear (5), planetary pinion (4) is paid ring gear (6) with planetary pinion, the number of teeth difference of planetary pinion (7) is unequal, under the effect of input shaft, eccentric shaft is done eccentric revolution, drive planetary pinion by bearing and do few tooth difference transmission with ring gear respectively, because ring gear (5) is fixed with housing, ring gear (6) is fixing with output shaft (11), planetary pinion (4), (7) be fixed into duplicate gear, make gear pair (4), (5) with gear pair (7), (6) small teeth number difference planet gear transmission constitutes compound motion, and equilibrium block can be eliminated eccentric shaft (2), (9) vibrations that produced.When the two-stage number of teeth difference of retarder equates, when modulus equated, eccentric shaft two throw of eccentric were equal.
