Abstract
The utility model discloses a decelerator for decelerated transmission between input and output components, in particular to a planetary reducer which pertains to the transmission apparatus field. The utility model comprises the input and output components, a sun wheel for decelerated transmission, wherein, the sun wheel is arranged between the input and the output components, and inner gear wheel and the planetary wheel that is located between the sun wheel and the inner gear wheel and can be engaged meanwhile; the planetary wheel is distributed on the circle between the sun wheel and the inner gear wheel by planetary frame. The output component consists of the output shaft and the planetary frame, and an extended end is arranged on the end of planetary frame; the extended end is embedded and inserted inside the hole of output shaft, which makes the output component consisting of the output shaft and the low speed plane through the bolt. The utility model solves the problems of the prior planetary frame of planetary decelerator as complex processing technology, large difficulty in processing, and needing the special device for processing, and reduces the volume and weight of the planetary frame.
Description
Affiliated technical field:
The utility model relate to a kind of can be used for importing and output link between the retarder of gearing down, particularly a kind of planetary reducer belongs to the mechanical transmission field.
Background technique:
Planetary reducer generally comprises input, output link, in input, be provided with the sun gear that constitutes gearing down between the output link, internal gear and the planet wheel that between the two, also is meshed with it simultaneously, planet carrier is distributed on the circumference between sun gear and the internal gear planet wheel, in such planetary reducer, output shaft and planet carrier are made into a substantial integral body, being about to the planet carrier end prolongs and enough length, serve as output shaft, this body structure of planet carrier more complicated, volume is big, and technological requirement is higher, and output shaft and planet carrier are made the volume weight that one has not only strengthened planet carrier, and since the part of serving as output shaft to process the bearing position and in, fit on face, this has just more increased the difficulty of processing of planet carrier, the inaccessible processing request of manufacturer of feasible general no special device.
Summary of the invention:
The purpose of this utility model is: a kind of above-mentioned the deficiencies in the prior art that overcome are provided, change the structure of planet carrier, make the processing technology difficulty of planet carrier reduce the improved planetary reducer that does not need special device to process.
The utility model is to realize above-mentioned purpose by following technical solution:
This planetary reducer is made up of input, output link, between input, output link, be provided with the sun gear that constitutes gearing down, internal gear and the planet wheel that between the two, also is meshed with it simultaneously, planet carrier is distributed on the circumference between sun gear and the internal gear planet wheel, it is characterized in that: output link is formed by output shaft and planet carrier connection, and there is an extending end planet carrier end, and this extending end edge is inserted in the hole of output shaft.Be provided with resilient bushing between planet carrier and the planet wheel shaft.The material of resilient bushing is a polyoxymethylene.
The utility model compared with prior art has following beneficial effect:
Because planet carrier and output shaft two-part for dividing, like this extending end of planet carrier end only need reserve can make output shaft circumferentially location and length that can the balance moment of flexure get final product and be linked together with planet carrier again after output shaft then can process separately, so avoided all processing requests are concentrated on the planet carrier.Thereby reduced the technology difficulty of planet carrier processing, made and under the situation of no special device, also can process.
Description of drawings:
Accompanying drawing is the overall structure sectional view of planetary reducer.
Among the figure: 1. output shaft, 2. output link, 3. extending end, 4. casing, 5. internal gear, 6. planet wheel, 7. bearing, 8. planet wheel shaft, 9. resilient bushing, 10. bidentate wheel coupling, 11. internal gears, 12. planet wheels, 13. bearing, 14. planet wheel shafts, 15. bidentate coupling, 16. input shafts, 17. high speed level planet carrier, 18. high speed level sun gears, 19. slow speed turbine stage planet carriers, 20. the slow speed turbine stage sun gear, 21. bolts, 22. holes.
Embodiment:
Shown in accompanying drawing, this planetary driving device is provided with gear for two stage planetary gear train, two internal gears (5) and internal gear (11) but be inlaid in after the machine shaping on the casing (4), also can directly go up processing at casing (4), planet wheels at different levels (6) and planet wheel (12) are all by the bearing (7) and bearing (13) supporting that are installed on planet wheel shaft (8) and the planet wheel shaft (14), what the utility model adopted is a pair of single-row centripetal roller bearing, level sun gear (18) connects with input shaft (16) by bidentate coupling (15) at a high speed, slow speed turbine stage sun gear (20) links by a bidentate wheel coupling (10) and a high speed level planet carrier (17) again, so just, having constituted low-speed sun pinion floats, the load balancing mechanism that high-speed carrier and sun gear float simultaneously, slow speed turbine stage planet carrier (19) is by resilient bushing (9) supporting planet wheel shaft (8), prevent slow speed turbine stage planet carrier (19) or planet wheel shaft (8) rapid wear, and can play buffering vibration, make the output of motion steady.Resilient bushing (9) is preferably made by material polyoxymethylene heat-resisting and that wear-resisting property is balanced, output link (2) is formed by output shaft (1) and slow speed turbine stage planet carrier (19) connection, the two can pass through bolt (21) and connect, there is an extending end (3) slow speed turbine stage planet carrier (19) end, this extending end (3) edge is inserted in the hole (22) of output shaft (1), the necessary long enough of the length of insertion, as: 50～80mm, with the circumferential location of assurance output shaft (1), and can bear certain bending moment.
Claims (3)
1. planetary reducer: form by input, output link, between input, output link, be provided with the sun gear that constitutes gearing down, internal gear and the planet wheel that between the two, also is meshed with it simultaneously, planet carrier is distributed on the circumference between sun gear and the internal gear planet wheel, it is characterized in that: output link is formed by output shaft and planet carrier connection, and there is an extending end planet carrier end, and this extending end edge is inserted in the hole of output shaft.
2. planetary reducer according to claim 1 is characterized in that: be provided with resilient bushing between planet carrier and the planet wheel shaft.
