Description
Technical field
The utility model relates to power transmission technical field, particularly relates to a kind of differential actuating unit.
Background technique
At present, on economic field, blanket retarder and speed increaser major part are all external gear pump drive mechanism and the planetary gear transmission mechanisms of coaxial line structure, are exactly by branched power formula external gear pump structure in the situation that of especially big moment.The slip ratio that increases gear engagement due to planetary gear transmission mechanism is drawn the effect of optimization to volume and quality, but moment is when very large, has to rely on external gear pump structure.Because coaxial line gear ratio deploying type gear transmission structure has had very large progress, always also fail to obtain sufficient effect, and in the level of needs, can not realize for the very volume of high-torque power transmitting deice and the optimization of weight.
Concerning the technical merit of gear driven type power transmitting deice, except the quantitative indexes such as volume and weight, depend on the quality index such as vibrations, noise, temperature rising, reliability, life-span.Now, in the solution process of gear driven type power transmitting deice technical merit, be mainly fixed against the physical characteristics (engineering index) such as quality (machining accuracy), material and heat treatment of manufacture.When solving the reliability of gear driven type power transmitting deice and life-span, under static strength condition, investigated manyly, the effect of the effect that does not take into full account unit to kinetic characteristic and dynamic characteristic.Although so the quality of manufacturing has been improved very much, also occur failing fully reducing and shaking and level of noise, or the shortcoming in unsecured reliability and life-span, thereby to economic development adverse effect.Particularly, on aspect super-huge gear type power transmitting deice, there is certain necessary very deep technical problem solving.Although because meet strength condition in Machine Design engineering, reach life time before, usually there is the phenomenon of the destroyed replacement of some gear.
At present, aspect Design and manufacture machine driven system, due to the narrow limitation of gear driven type power transmitting deice technology, just fail to improve starting characteristic and fail to reduce the power source number of electrodes of (comprising motor and generator), thereby cause very big energy loss.Now the number of electrodes of high power motor be nearly all 8 extremely more than, and for generator, even rise to 24,48 extremely more than.Here it is while obtaining identical moment on economic aspect, fails one of reason reducing power consumpiton.In the past, in prime mover part of machine driven system, the in the situation that of same power, because failing to reduce volume and quality cost is also high, and the unit materials consumption of gear driven type power transmitting deice increases, and in a word, the manufacture cost of product is high.
Model utility content
For solving the problems of the technologies described above, the utility model provides the differential actuating unit that a kind of transmission is safe and reliable and operate steadily.。
Differential actuating unit of the present utility model, comprise casing, the outside side of described casing is provided with motor, described box house is provided with driving gear, differential gearing gear, driving shaft, hinged support, differential gear, gear of output end, driven gear and driven shaft, described motor is connected with described driving gear and driving gear rotation on earth, described driving gear matches with described differential gearing gear, described differential gearing gear is set on described driving shaft by described hinged support, the opposite side of described differential gearing gear matches with described differential gear, the described driving shaft the other end is provided with gear of output end, described driven gear matches with described gear of output end, described driven gear is set on described driven shaft.
Optionally, be also provided with differential gear wheel shaft and be set in the sliding bearing on described differential gear wheel shaft in described casing, described differential gear is arranged on described differential gear wheel shaft by described sliding bearing.
Optionally, described differential gear is stepped gear.
