Described by engine-driven gear stepped transmission that surmounts, structural principle is the power object difference of getting with [0008].3. beneficial effect:
The gear stepless speed variator that surmounts of the present invention, by the clockwise and anticlockwise displacement of four control device control leading screw cranks, promptly control the velocity ratio i of rack pinion, i.e. the rotating speed that advances of can regulate output shaft, hypervelocity rotating speed, reverse gear rotating speed, portion is stepless, and also can obtain the neutral gear rotating speed is 0.Conversion is arranged on the position of the middle shift fork of linkage gear, the i.e. positive and reverse steering of can regulate output shaft.The gear stepless speed variator that surmounts of the present invention not only can replace traditional speed changer, and can substitute the automatic transmission in the vehicle.Number of spare parts of the present invention is used in has only 173 in the automatic transmission, compare with A341E and A342E automatic transmission in the Japanese Lexus LS400 car, and A341E and A342E automatic transmission overall number of components reach 435, and overall number of components reduces 60%.The Z3040x16 type radial drilling machine that China designs voluntarily, gear rack add totally 51 of worm and gears, if go to drive with two cycloidal-pin wheel reducing motors of the present invention, need only 12 of gears, and the gear part sum reduces 78%.Go design if surmount gear mechanism with hydraulic pressure of the present invention, gear quantity has only 8, and the part sum reduces 84%, 60 gears of X6132 type milling machine, 56 of gear hobbing machine tool gears sums; Go design with this law, number of spare parts can reduce 62%.Surmount gear stepless speed variator and also be suitable for the design of dryer, double rotor flapping-wing aircraft, double rotor grab bucket, timber lathe, double drum wheel slicer, road heading machinery etc.Moreover, and can substitute traditional friction driving product.There is many can the connection with this core technology in existing mechanism, produces new equipment.Traditional tidal power generation need be built reservoir, and construction investment is big, if the unidirectional generating in single storehouse, generating dutation are 9-11 hour, if the two-way generating in single storehouse (two-way water turbine is installed), generating dutation also has only 14 1 16 hours, also has the one-way type generating of two storehouses, and generating dutation did not reach 24 hours yet.If use the present invention to surmount the tidal power generating device of gear transmission speedup, generating dutation is 23-24 hour, and generating dutation is long, less investment.
The double rotor output mechanism that surmounts gear stepped transmission of the present invention, two reverse output shafts constitute dual-rotor structure, can be used for stirrer, propeller cavitation, development machine, honing machine, saw blade or the like.Helicopter can increase lift with twin screw, improves the stability and the airborne amount of helicopter; Principle with the double rotor multiatage axial flow compressor can be made lightweight gas turbine, is used for power field, aviation field, also can be applicable to the robot research field; Surmount gear double rotor principle and also can be applicable on the light-duty rotation three-dimensional radar (non-phased-array radar and lidar), realize the omnidirectional tracking in high-altitude and low latitude.Be used for axial flow hydraulic turbine; can make traditional axial flow hydraulic turbine active wheel become twin screw by single propeller cavitation; make its generating capacity improve 40-50%; surmounting gear double rotor output mechanism is applied in the reaper of farm machinery; in the axial flow double rotor rotating drum threshing machine, make reaper and threshing machine raise the efficiency 1 times.Surmount gear and be applied in before and after four-wheel (or the six take turns) driven vehicles in the differential mechanism, can obtain extraordinary differential lock mechanism, prevent that automobile from skidding, simple in structure more a lot of than differential lock in the Torsen differential mechanism.The Torsen differential mechanism is installed on Audi 80 and 90 automobiles 6 worm gears, and 6 worm screws and 12 spur gears and 2 worm screws of antero posterior axis are formed, and differential carrier has spline to be connected with hollow shaft.3 worm-wheel shafts are installed along chord lengths such as differential carrier circular cross sections, see that thus Torsen differential lock structure is very complicated.Gear stepless speed variator of the present invention is non-slip, transmitted power is big, transmission efficiency is high, speed ratio accurately and reliably, speed-regulating range width, service life of gear is long.Practical speed ratio R=0-150 of the present invention, traditional speed ratio R=2-5 can.When the liquid presses piston pole tooth bar directly drives gearwheel,, can produce huge running torque by 2 grades of decelerations.By 4 grades of speedups, can realize tidal power generation.4. working principle:
Surmount gear stepless speed variator and surmount gear stepped transmission, stepless rotating speed that will be by a different modes input or grade rotating speed is arranged through the rectification of the gear assembly on the jack shaft, makes the to-and-fro motion of tooth bar and piston rod tooth bar be converted to unidirectional rotating speed output.
