The 3rd installation shaft 9 and 10 liang of output shaftsPerson's axial direction is parallel to each other. Said structure can be realized the transmission from driving force, and it hasBe convenient to dismounting, maintenance, and advantage simple in structure.
As preferably or alternatively embodiment of one, the centre bore of secondary duplicate gear 3 andBetween one installation shaft 4 and/or between the centre bore of three grades of duplicate gears 5 and the second installation shaft 6 and/ or the centre bore of secondary gear 8 and the 3rd installation shaft 9 between be connected by bearing.
Bearing can reduce the frictional force of movable connection structure effectively, improves transmission efficiency.
As preferably or alternatively embodiment of one, secondary duplicate gear 3, three grades of duplex-gearsWheel 5, secondary gear 8 and tertiary gear 11 number are separately at least two.
Multiple secondary duplicate gears 3 and multiple three grades of planetary gear speed reducing mechanisms that duplicate gear 5 formsIn, each strength of gear is comparatively balanced, and not only the process of transmission mechanism transferring power is comparatively steady,And the reliability of transmission mechanism is even more ideal.
As preferably or alternatively embodiment of one, internal gear 71 is preferably pivoting support 7Inner ring, fixed body 1 is fixedly connected with the outer ring of pivoting support 7 or both are for integral typeStructure.
Being fixedly connected with to be preferably of the outer ring of fixed body 1 and pivoting support 7 used bolt to be connected.
Pivoting support 7 is again turntable bearing, is a kind of large size bearing that can bear combined load,Can bear simultaneously larger axially, radial load and tilting moment.
Said structure utilizes the inner ring of pivoting support 7 as the ring gear of epicyclic transmission mechanism, inGear ring rotates as output speed. Owing to having roller between the inner ring of pivoting support 7 and outer ringOr ball, so the frictional force between upper shell and lower house is less, the transmission effect of revolution powerRate and transmission efficiency are high.
As preferably or alternatively embodiment of one, fixed body 1, revolution power output 12Be the shell of reductor, the outer upper shell of fixed body 1, revolution power output 12 is lower house.
Between fixed body 1, pivoting support 7 and revolution power output 12, form liquid sealing chamberChamber, secondary duplicate gear 3, three grades of duplicate gears 5, secondary gear 8 and tertiary gears 11Within being all positioned at liquid sealing chamber.
Liquid sealing chamber has formed full-closed structure, and this structure can make all gear members and peace thereofBearing between dress axle, gear and installation shaft, in the housing of a sealing, has reduced reductorThe probability of leakage of oil.
Below by reference to the accompanying drawings 2 and Fig. 3 concentrate explanation optimal technical scheme provided by the invention:
In the reductor that optimal technical scheme provided by the invention provides:
Fixed body 1 is that the outer ring of upper shell and pivoting support 7 fixes. Input gear axle 2Power is delivered to the power intake of input gear axle 2 by shaft coupling by motor. Secondary duplexIt is fixed on fixed pin shaft I in the first installation shaft 4 by bearing gear 3. Fixed pin shaft II.e. the first installation shaft 4, itself and upper shell are fixedly connected. It passes through axle three grades of duplicate gears 5Holding and being fixed on fixed pin shaft II is in the second installation shaft 6. Fixed pin shaft II i.e. the second installation shaft 6,Itself and upper shell are fixedly connected. Pivoting support 7 its inner rings, outer ring can relatively rotate, outerCircle is connected with upper shell, and inner ring is connected with lower house. It is fixed on secondary gear 8 by bearingFixed pin shaft III i.e. the 3rd installation shaft 9. I.e. the 3rd installation shaft 9 of fixed pin shaft III, itself and lower houseBe fixedly connected. The rotation output shaft 10 that output shaft 10 is reductor. Tertiary gear 11 is with defeatedShaft 10 is connected. The inner ring of lower house and pivoting support 7 fixes.
Power is inputted by input gear axle 2, input gear axle 2 first with secondary duplicate gear 3Gear wheel end engagement, secondary duplicate gear 3 around fixed pin shaft I the first installation shaft 4 rotate,The pinion end of secondary duplicate gear 3 (pinion end or title: pinion, also can be called for short:Small end) with the gear wheel end of three grades of duplicate gears 5 (gear wheel end or title: gear wheel, also canTo be called for short: end greatly) engagement, three grades of duplicate gears 5 are around i.e. the second installation shaft 6 of fixed pin shaft IIRotation, the pinion end of three grades of duplicate gears 5 engages with pivoting support 7 inner rings, thereby drivesInner ring rotation. Outer ring and the upper shell of pivoting support 7 are fixed together, and inner ring and lower house are solidFix on together, inner ring drives lower house to rotate together, thereby makes reductor have a revolution speedDegree. Input gear axle 2 engages with secondary gear 8 simultaneously, and secondary gear 8 is around fixed pin shaftIII i.e. the 3rd installation shaft 9 is rotated, and secondary gear 8 engages with tertiary gear 11, drives three grades of teethWheel 11 rotations, tertiary gear 11 is fixed together with output shaft 10, makes reductor have oneRotation output.
The revolution output of the reductor that in sum, optimal technical scheme of the present invention provides adopts rowStar slows down, and first carries out double reduction by two duplicate gears, utilizes pivoting support 7 simultaneouslyThe rotatable characteristic of Internal and external cycle, exports the inner ring speed of pivoting support 7 as revolution speed,Make total compactness, transmission efficiency high, less parts can improve the assembling effect of reductorRate. Reductor rotation utilizes input gear axle 2 rotating speeds to obtain output speed through double reduction.Whole reductor adopts totally-enclosed design, and all gear members, in the housing of a sealing, reduceThe probability of reductor leakage of oil.
As shown in Figure 2 to 3, the Mixing Machine that the embodiment of the present invention provides, comprises that first stirsMix the arbitrary technical scheme reductor of body, the second stirring body and the present invention, wherein:
The first stirring body and the second stirring body include blade keeper and and blade separatelyKeeper is fixedly connected with or is the stirring vane of integral type structure.
