The beneficial effects of the utility model are mainly: (1) different standard pitch circle of the present utility model slow down reversible reduction gear arrangement simple, manufacture simple and easy, low price, medium transfer ratio can be reached; (2) volume is little, lightweight, efficiency is high; (3) adjustable clockwise and anticlockwise, multi-change speed is realized; (4) operate steadily, noise is little; (5) easy for installation, superior performance.
Accompanying drawing explanation
Fig. 1 is that different standard pitch circle of the present utility model slows down the overall structure schematic diagram of reversible reduction gear.
Fig. 2 is that different standard pitch circle of the present utility model slows down the structural blast figure of reversible reduction gear.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Figure 1-2, different standard pitch circle slows down reversible reduction gear, and comprise input shaft 1, input shaft is connected with line of input carrier 21 time, line of input carrier 2 be provided with 3 along the circumferential interval of line of input carrier 2 equally distributed different tooth associating planetary gear set 3.Particularly, this different tooth associating planetary gear set 3 comprises two directions along input shaft 1 and to arrange successively the first associating planetary pinion 31 and the second associating planetary pinion 32 that the concentric that is fixed together and reference radius do not wait.Line of input carrier 2 be socketed with fixing ring gear 4 and export ring gear 5, and fixing ring gear 4 and do not export ring gear 5 concentric, reference radius not etc., wherein, the first associating planetary pinion 31 is meshed with fixing ring gear 4, and the second associating planetary pinion 32 is meshed with output ring gear 5.This shows that this different standard pitch circle slows down reversible reduction gear arrangement simply, can effectively reduce design difficulty and fabricating cost.
Two associating planetary pinions in the present embodiment are fixed together with dead in line, and with it for input driving component, drive fixing ring gear 4 and export ring gear 5 and rotate.
In the present embodiment, preferably the height H of fixing ring gear 4 equals the height H of the first associating planetary pinion 31
1, the thickness h exporting ring gear 5 equals the thickness h of the second associating planetary pinion 32
1.The number of teeth of the first associating planetary pinion 31 and the second associating planetary pinion 32 is equal or not etc., can needed for actual production, the planetary modulus of adjustment two associating, makes the number of teeth of two gears equal or not etc., to realize multi-change speed.Particularly when the two combination gear numbers of teeth do not wait, effectively can increase the range of choice of transfer ratio.
In the present embodiment, different tooth associating planetary gear set 3 is positioned on planet carrier 2 by edge connection in locating stud 6.Certainly in other embodiments of the present utility model; different tooth associating planetary gear set 3 also can connect by other means and is positioned on planet carrier 2; this is not restricted, as long as the function that can substitute locating stud 6 mosaic mode is all within protection domain of the present utility model.
If the radius of fixing ring gear 4 represents with D11, the radius exporting ring gear 5 represents with D21, and the radius of the first associating planetary pinion 31 represents with D12, and the radius of the second associating planetary pinion 32 represents with D22, wherein, D11, D21, D12, D22 meet relation:
D22＝D12+(D21-D11)；
Wherein, when different tooth associating planetary pinion 3 turns around along system centre axle, (1-(D11*D22)/(D12*D21)) * 360 spends relative to the relative movement of fixing ring gear 4 to export ring gear 5, and velocity ratio is 1/ (1-(D11*D22)/(D12*D21)).
In this case, power is passed in line of input carrier 2 by input shaft 1, thus drives the different tooth associating driving gear set 3 on planet carrier 2 to rotate, and different tooth associating driving gear set 3 is rotated around fixing ring gear 4, thus drives output ring gear 5 to rotate, outputting power; When the reference radius D11 of fixing ring gear 4 is greater than the reference radius D21 exporting ring gear 5, export and input in the same way, retarder rotates forward, when the reference radius D11 of fixing ring gear 4 is less than the reference radius D21 exporting ring gear 5, export with input reverse, retarder reverses.Therefore transfer ratio wider range of reduction gear of the present utility model.Due to the distribution of 3 different tooth associating planetary gear set 3 Homogeneous Axisymmetricals, make different tooth combine planetary gear set 3 uniform force, operate steadily.
In the present embodiment, the structure of preferred 3 different tooth associating planetary gear set 3 is all consistent, makes different tooth combine planetary gear set 3 uniform force, operates steadily.
The above only lists the way of realization of the utility model design; protection domain of the present utility model should not be regarded as being only limitted to the concrete form that embodiment states; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
