Abstract
The utility model discloses a planetary gear driving system comprising a main shaft, a sun gear sleeved on the main shaft and a planetary disk gear, wherein a planetary gear shaft parallel to the main shaft is arranged on the planetary disk gear, a planetary gear engaged with the sun gear is sleeved on the planetary gear shaft, and the planetary gear shaft is an eccentric shaft. According to the utility model, the planetary gear shaft is the eccentric shaft, if a gap is generated between the engaged planetary gear and the sun gear because of friction, the eccentric shaft can be rotated to shorten the distance between the axial lines of the planetary gear and the sun gear so as to eliminate the gaps between the engaged teeth of the two gears to recover the system precision.
Description
Technical field
The utility model relates to a kind of driving mechanism, relates in particular to a kind of planetary transmission system.
Background technique
Much all will adopt the planetary kind of drive on the mechanical transmission so that the transmission speed and the moment of adjustment equipment, but there is a lot of problems in existing epicyclic gear system, for example precision is difficult to keep, and stability is not enough etc.Planetary pinion and sun gear are intermeshing in the existing epicyclic gear system; But after using the long period, because rubbing action, the gap can appear in the engagement place; Thereby influence transmission accuracy; And can't adjust voluntarily, as through the electric means adjustment, can increase the coefficient of cost and wearing and tearing.
Summary of the invention
The utility model provides a kind of planetary transmission system, has solved the problem that the gap of appearance can't be adjusted after the wearing and tearing between traditional epicyclic gear system gear.
A kind of planetary transmission system; Comprise main shaft; Be set on sun gear and planetary plate gear on the main shaft; Said planetary plate gear is provided with the planet pin with spindle parallel, and said planet pin upper sleeve through has and the sun gear planet gear meshed, and described planet pin is an eccentric shaft.
Described sun gear quantity is two, and wherein first sun gear directly is solidly set on the main shaft, and secondary sun wheel is set on the main shaft through bearing.
Described main shaft upper sleeve through has the driving gear with the secondary sun wheel interlock.
Described planetary plate gear is made up of planetary pinion tube and the gear ring that is fixed on the planetary pinion tube.
The utility model planet pin is an eccentric shaft; Between planet gear meshed and sun gear because of the friction-produced gap, can eccentric rotation axis, dwindle the distance between planetary pinion and the sun gear axis; And then eliminate the gap between their both engaging tooths, recovery system precision.
Description of drawings
Fig. 1 is the structural representation of the utility model planetary transmission system.
Embodiment
As shown in Figure 1; A kind of planetary transmission system; Comprise main shaft 1, be set on sun gear 4,5, driving gear 6 and planetary plate gear 2 on the main shaft, wherein be provided with bearing between sun gear 4, driving gear 6 and planetary plate gear 2 and the main shaft; And sun gear 5 directly is to be fixed on the main shaft 1, sun gear 4 and driving gear 6 interlocks.
Planetary plate gear 2 is made up of planetary pinion tube 201 and the gear ring 202 that is fixed on the planetary pinion; Planetary plate gear 2 is provided with the planet pin 7 parallel with main shaft 1; Planet pin 7 is an eccentric shaft, is with planetary pinion 3 on its eccentric segment, is provided with bearing between them; Planetary pinion 3 all meshes with sun gear 4,5, and this system comprises 3 planetary pinions with the number of teeth.
Owing to planetary pinion 3 and sun gear 4, have frictional force between 5, after long-term the use, the gap can appear between cog, influence transmission accuracy, rotates planet pin 7, can eliminate inter-lobe clearance, the recovery transmission accuracy.
