Abstract
The utility model discloses a carrier structure of a planetary reducing mechanism. The frame structure of the planetary reducing mechanism comprises a planet carrier, a planetary gear and a partition. A plurality of through holes are formed in the planet carrier. One bolt is fixed in each of the through holes and the planetary gear is in rotating connection with the bolt. Spacers are arranged on two end faces of the planetary gear. A slot is arranged on the end portion of the bolt. A retainer ring is arranged in the slot. All the bolts penetrate the partition arranged between the ring and the spacers. Since all the bolts penetrate the partition and the partition can not be driven to relatively rotate when the single planetary gear rotates, the partition cannot relatively rotate with the retainer ring and the abrasion of the retainer ring is avoided.
Description
Technical field
The utility model relates to a kind of reducing gear, relates in particular to a kind of frame structure of planetary gear speed reducing mechanism.
Background technique
Characteristics such as planetary speed reducer is in light weight, volume is little, gear range is big, efficient is high, running is steady, the low adaptability of noise is strong.Speed reducer is widely used in industrial departments such as metallurgy, mine, lifting transportation, electric power, the energy, building materials, light industry, traffic.
Referring to Fig. 1, the frame structure of planetary gear speed reducing mechanism comprises planet carrier 1 and planetary pinion 2, and described planet carrier 1 is provided with through hole 11, in the described through hole 11 latch 3 is arranged fixedly, and described planetary pinion 2 is rotatably connected on the latch 3.All be provided with pad 21,22 on two end faces of planetary pinion 2.In order to prevent that planetary pinion 2 from skidding off from latch 3, the end of described latch 3 is provided with draw-in groove 31, is provided with a back-up ring 32 in the described draw-in groove 31.
During use, planetary pinion 2 rotates under the drive of central gear, and back-up ring 32 and planet carrier 1 do not rotate, and pad 21,22 plays an insulating effect, friction planet carrier 1 and back-up ring 32 when preventing planetary pinion 2 rotations.When but planetary pinion rotates, still can drive pad and rotate, especially relatively rotating between pad and the back-up ring can make the back-up ring wearing and tearing, and then cause planetary pinion to move outward, causes transmission failure.
Summary of the invention
The utility model provides the frame structure of planetary gear speed reducing mechanism at deficiency of the prior art, can prevent that filling up back-up ring weares and teares.
For solving the problems of the technologies described above, the utility model is solved by following technical proposals: the frame structure of planetary gear speed reducing mechanism, comprise planet carrier and planetary pinion, described planet carrier is provided with a plurality of through holes, in each described through hole a latch is arranged fixedly, described planetary pinion is rotatably connected on the latch.All be provided with pad on planetary two end faces, the end of described latch is provided with draw-in groove, is provided with a back-up ring in the described draw-in groove, also comprises a dividing plate, and all described latches pass described dividing plate, and described dividing plate is between described back-up ring and described pad.Because all latches all pass dividing plate, when single planetary pinion rotates, can not drive dividing plate and relatively rotate together, so dividing plate can not relatively rotate with back-up ring, avoid back-up ring to wear and tear.
Above-mentioned technology is in the scheme, and is preferred, is provided with bearing between described planetary pinion and the described latch.Frictional force when bearing can reduce the planetary pinion rotation is increased work efficiency.
Above-mentioned technology is in the scheme, and preferred, the neutral position of described planet carrier is provided with internal gear.Internal gear matches with output shaft, with the power output of retarder.
The beneficial effects of the utility model are: because all latches all pass dividing plate, when single planetary pinion rotates, can not drive dividing plate and relatively rotate together, so dividing plate can not relatively rotate with back-up ring, avoid back-up ring to wear and tear.
Description of drawings
Fig. 1 is the schematic representation of the frame structure of existing planetary gear speed reducing mechanism.
Fig. 2 is the utility model embodiment's schematic representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: referring to Fig. 2, the frame structure of planetary gear speed reducing mechanism comprises planet carrier 1, planetary pinion 2 and dividing plate 4.Be processed with a plurality of through holes 11 on the end face of planet carrier 1, these through holes 11 circumferentially evenly distribute along the end face of planet carrier 1.In each through hole 11 latch 3 is arranged fixedly, latch is fixed in the through hole 11 by the mode of interference fit.The neutral position of planet carrier 1 is provided with internal gear 12.
Planetary pinion 2 is rotatably connected on the latch 3.Concrete, latch 3 is provided with bearing 4, and the inner ring of bearing 4 is fixed on the latch 3, and the outer ring of bearing 4 links to each other with planetary pinion 2 inner rings.Frictional force when bearing 4 can reduce planetary pinion 2 rotations.
All be provided with pad 21,22 on two end faces of planetary pinion 2, the end of latch 3 is provided with draw-in groove 31, is provided with a back-up ring 32 in the draw-in groove 31.All latches 3 pass dividing plate 4, and dividing plate 4 is between back-up ring 32 and pad 21.
During use, central gear drives planetary pinion 2 and rotates, and planetary pinion 2 drives pad 21,22 and rotates when rotating.When pad 21 rotated, the bottom of friction spacer 4 was a plurality ofly located by latch 3 but have on the dividing plate 4, and dividing plate 4 can't just can not relatively rotate with back-up ring 32 with pad 21 rotations yet.So dividing plate can completely cut off the friction between pad 21 and the back-up ring 32, avoid taking place back-up ring and damage because of wearing and tearing.
