Abstract
The utility model relates to a double-row planetary drive gearbox, which is composed of an input shaft, a left planetary gear train, a right planetary gear train, a backing and a going clutches, an output shaft, a box body and a hydraulic pressure system, wherein, power is transferred to the output shaft via the input shaft and a planetary gear system to manipulate hydraulic pressure to control the opening and the closing of the backing and the going clutches; different combination of drive gears can be obtained, consequently realizing the decelerating positive and the reverse rotation or the idle rotation of the output shaft The gearbox is used for the power systems of a ship and engineering machinery, and has the advantages of compact structure, small volume, light weight, strong bearing capacity, low noise, stable drive, operational safety, long service life, convenient maintenance, low cost, etc.
Description
The utility model relates to a kind of speed reduction gearing, is particularly useful in the power system of steamer or construction machinery and equipment, can finish deceleration, ahead running, a kind of new gear case of function such as reversing, neutral.
At present, the gear case that uses in steamer or the construction machinery and equipment adopts the stud wheel transmission of parallel multiaxis garden, its structure as shown in Figure 1:
Among Fig. 1,1---input shaft, 2---input gear, 3---the ahead running clutch gear, 4---the reverse clutch gear, 5---the ahead running power-transfer clutch, 6---the ahead running driving gear, 7---reverse clutch, 8---the reversing driving gear, 9---the output big gear wheel, 10---output shaft.
The major defect of said gear case is: one, the transmission middle gear is by the monodentate engagement, and in the high pulling torque transmission, the modulus of gear is very big, Gear Processing expense height.Two,, damage causing the accident easily because monodentate engaged transmission axle is stressed asymmetric, and its bearing bears very big warp-wise load.Three, owing to reasons in structure, the casing width surpasses the driving engine width, uses inconvenience is installed.
The purpose of this utility model is, provides a kind of load-carrying capacity strong, and volume is little, and is in light weight, handling ease, use reliable, double planet pinion case easy for installation.
The purpose of this utility model is achieved in that the input shaft of packing into, sun gear, left lateral gear rack, left lateral star gear, left inner gear, right lateral gear rack, right lateral star gear, right inner gear, output shaft, ahead running power-transfer clutch, reverse clutch etc. in casing, form double planet pinion system.Sun gear of double planet pinion system share, a public input shaft, a public output shaft.By the combination of the different gears of double planet pinion internal system, realize slowing down, ahead running, functions such as reversing, neutral.Because in planetary transmission, can arrange a plurality of (3---5) planetary wheel around sun gear, thus in transmission, there is multiple sets of teeth to mesh simultaneously, and the load that each tooth is shared can reduce greatly, thus module of gear also can correspondingly reduce.Because planetary wheel is symmetrically distributed on week in same garden, sun gear can not produce warp-wise power on inner gear, the planetary gear carrier, so its block bearing does not bear warp-wise load yet in addition.The planetary transmission compact conformation, box sizes can reduce greatly.
Owing to adopt such scheme, module of gear has reduced greatly, it is easy that Gear Processing will become, its expense reduces, and block bearing does not bear very big warp-wise load simultaneously, and bearing life will improve greatly, can increase the reliability of use, box sizes has reduced in addition, expendable weight not only, and give to use to install and bring very big convenience.
Below in conjunction with accompanying drawing, the utility model is further specified.
Fig. 2 is a structure principle chart of the present utility model.
Among the figure, 1---input shaft, 2---reverse clutch, 3---the left lateral gear rack, 4---left inner gear, 5---right inner gear, 6---the right lateral gear rack, 7---the ahead running power-transfer clutch, 8---output shaft, 9---left lateral star gear, 10---sun gear, 11---right lateral star gear, 12---oil cylinder, 13---oil cylinder, 14---change-over valve.
In Fig. 2, input shaft 1 is fixed as one with sun gear 10, and left lateral gear rack 3 is sleeved on the input shaft 1, and reverse clutch 2 connects with left lateral gear rack 3 by spline one end, and the other end connects with casing.Left side inner gear 4 is fixed as one with right lateral gear rack 6 output shafts 8.Right inner gear 5 is sleeved on the output shaft 8.Ahead running power-transfer clutch 7 connects with right inner gear 5 by spline one end, and the other end connects with casing.Left lateral star gear 9 is contained on the left lateral gear rack 3, interior and sun gear 10 engagements, outer and left inner gear 4 engagements.Right lateral star gear 11 is contained on the right lateral gear rack 6, interior and sun gear 10 engagements, outer and right inner gear 5 engagements.Reverse clutch 2 is by oil cylinder 13 and change-over valve 14 control foldings, and ahead running power-transfer clutch 7 is by oil cylinder 12 and change-over valve 14 control foldings.Transmission principle is such: neutral, change-over valve 14 mediates, reverse clutch 2 and ahead running power-transfer clutch 7 all are in disengaged condition, left lateral gear rack 3 and right inner gear 5 all are in free state, input shaft 1 can not be to output shaft 8 transfer torques, sun gear 10 can only dally, and at this moment is convenient to engine starting.Ahead running: change-over valve 14 is in location right, ahead running power-transfer clutch 7 closes under the effect of oil cylinder 12, reverse clutch 2 is still thrown off, at this moment right inner gear 5 is braked, transmission is input shaft 1 in proper order---sun gear 10---right lateral star gear 11---right lateral gear rack 6---output shaft 8, this moment output shaft 8 turn to identically with input shaft 1, be used to advance.Reversing: change-over valve 14 is in left position, reverse clutch 2 closes under the effect of oil cylinder 13, and ahead running power-transfer clutch 7 is thrown off, at this moment left lateral gear rack 3 is braked, transmission is input shaft 1 in proper order---sun gear 10---left lateral star gear 9---left inner gear 4---right lateral gear rack 6---output shaft 8, this moment output shaft 8 turn on the contrary with input shaft 1, be used to retreat.Slow down: change the number of teeth combination of sun gear, planetary wheel, inner gear, can obtain 2.5---10 times different reduction ratios.
Realization of the present utility model does not have special technical requirement, and all other parts can adopt on the corresponding universal machine tools to be processed, i.e. universal process processing.
