Detailed description of the invention
This detailed description of the invention provides a kind of planetary reducer, when it can avoid moment of torsion moment to become large,The gear of reductor is the problem of damage easily.
Below, with reference to accompanying drawing, embodiment is described. In addition the embodiment shown in, is not to rightRequire the summary of the invention of recording to play any restriction effect. In addition, embodiment represented formation belowThe solution of the invention that full content is not limited to record as claim is necessary.
Refer to Fig. 1-Fig. 4, a kind of planetary reducer that this detailed description of the invention provides, comprise ring gear 11,Planetary gear 12, casing 13 and resilient snubber 14.
Wherein, planetary gear 12 is meshed with the internal tooth of ring gear 11 and carries out public affairs along the inner ring of ring gear 11Turn, ring gear 11 is enclosed within the inside of casing 13, and ring gear 11 can rotate with respect to casing 13.
Resilient snubber 14 is arranged between casing 13 and the periphery of ring gear 11, in the time that ring gear 11 rotates,Resilient snubber 14 produces the elastic force with ring gear 11 direction of rotation.
In the time that planetary reducer is worked, planetary gear 12 revolves round the sun and rotation in ring gear 11, when negativeCarry or moment of torsion moment while becoming large, planetary gear 12 can drive ring gears 11 to rotate suddenly, due to ring gear 11And between casing 13, being provided with resilient snubber 14, resilient snubber 14 produces elastic deformation, recovery deformationActive force is the damping force that stops ring gear 11 to rotate, and then effectively buffering has been fallen the moment of torsion of unexpected increase,Drive disk assembly is formed to effective protection, avoided because of load or the increase of moment of torsion moment, and damaged driving sectionThe problem of part. In addition, in technical scheme provided by the invention, between ring gear 11 and casing 13, be provided with bulletProperty bolster 14, belong to the unsteady load balancing mechanism pattern of ring gear 11, this load balancing mechanism not only can be balancedLoad, the bearing capacity of raising gear, also can reduce running noise, improves stationarity and reliability, withTime can also reduce the requirement to the accuracy of gear, thereby reduce manufacturing cost.
