Abstract
The utility model relates to a multi-shaft planetary differential speed reducer with a duplex gear, which is formed by that a planetary speed reducing mechanism and a differential speed reducing mechanism are connected in series. A planetary speed reducer comprises a sun wheel, a planetary wheel and a fixed tooth ring, wherein, the sun gear, the planetary wheel and the fixed gear ring are meshed in order; the planetary wheel is composed of two gears in rigid connection; one gear is meshed with the sun wheel and the fixed tooth ring; the other gear is meshed with a moving inner tooth ring; the diameter difference of the two gears of the duplicate gear is equal to the diameter difference of the fixed tooth ring and a moving tooth ring which is provided with a power output shaft in the axial direction. The utility model can obtain larger speed reducing ratio, simple structure, smaller volume and higher efficiency by that few components are added on the basis of the planetary speed reducer.
Description
The utility model relates to a kind of gear type speed reducer, particularly a kind of gear-driven structure of gear type speed reducer.
In the prior art, planetary speed reducer has intermeshing sun gear, planetary pinion and decides ring gear, and the axle of sun gear is a power input shaft, and planetary pinion drives a driving wheel, and the axle of driving wheel is a pto, the exportable low rotating speed of rotating speed than input.The reduction speed ratio of this speed reducer is generally smaller, need just need what reducing gear and be cascaded than the occasion of big retarding ratio, causes that the speed reducer volume is big, efficient is low.
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose the gear type speed reducer that a kind of reduction speed ratio is big, volume is little, efficient is higher.
The utility model is realized with the following method.
Multiaxis duplicate gear planet differential speed reducer is a kind of gear type speed reducer, multiaxis duplicate gear planet differential speed reducer has the sun gear of the order engagement identical with common planetary speed reducer, planetary pinion and decide ring gear, the axle of sun gear is a power input shaft, different with common planetary speed reducer is, its planetary pinion is a duplicate gear, duplicate gear has coaxial two gears that are parallel to each other, gear of duplicate gear is with above-mentioned sun gear and decide ring gear and be meshed, another gear of duplicate gear is meshed with another moving ring gear, moving ring gear axle axially arranged, the axle of moving ring gear is a pto.Two gear diameters of duplicate gear are unequal, and the diameter of deciding ring gear and moving ring gear is also unequal, the difference of two gear diameters of duplicate gear and decide ring gear and equate with the difference of moving ring gear diameter.
This speed reducer is equivalent to be composed in series by planetary gear speed reducing mechanism and differential reducing gear.The ratio of the rotating speed of the rotating speed of power input shaft and duplicate gear revolution can be considered the reduction speed ratio i of planetary gear speed reducing mechanism
OKExpression, the reduction speed ratio i of differential reducing gear
DifferenceExpression, reduction speed ratio i then of the present utility model should be the reduction speed ratio i of planetary gear speed reducing mechanism
OKReduction speed ratio i with the differential reducing gear
DifferenceProduct, i.e. i=i
OK* i
DifferenceThe difference of two gear diameters of duplicate gear less than one in the duplicate gear with above-mentioned sun gear with when deciding the diameter of the gear that ring gear is meshed, i
DifferenceAbsolute value greater than 1.i
DifferenceI is just changeed in output when being positive number
DifferenceOutput counter-rotating when being negative.The difference of two gear diameters of the duplicate gear of this multiaxis duplicate gear planet differential speed reducer less than one in the duplicate gear with sun gear with decide the diameter of the gear that ring gear is meshed.The difference of two gear diameters of duplicate gear is more little, i
DifferenceBig more, its variance ratio is very big.
Multiaxis duplicate gear planet differential speed reducer can only increase parts seldom on the basis of planetary speed reducer, can obtain bigger reduction speed ratio, and simple in structure, and volume is less relatively, and efficient is higher.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of multiaxis duplicate gear planet differential speed reducer.
Among Fig. 1, multiaxis duplicate gear planet differential speed reducer is composed in series by planetary gear speed reducing mechanism 1 and differential reducing gear 2 usefulness duplicate gears 3.Planetary gear speed reducing mechanism 1 dynamic input shaft 4, sun gear 12 is arranged on the power input shaft, compound planet gear 3 is arranged in this speed reducer, compound planet gear is rigidly connected by planetary pinion 31 and planetary pinion 32 and forms, be engaged with one～six planetary pinion 31 around the sun gear 12, compound planet gear 3 preferably has four, outside the circumference of planetary pinion 31, be engaged with and decide ring gear 11, planetary pinion 32 is meshed with moving ring gear 21, and the difference of the diameter of planetary pinion 31 and the diameter of planetary pinion 32 and the diameter of deciding ring gear 11 equate with the difference of the diameter of moving ring gear 21.The difference of the diameter of the diameter of planetary pinion 31 and planetary pinion 32 is less than the diameter of planetary pinion 31.The axial axle 5 of moving ring gear 21 is ptos.
