Embodiment
The embodiment who provides below in conjunction with accompanying drawing is further described the utility model.
What present embodiment provided is to be used for the step-up system that the dismounting of car rear axle semi-axis sleeve pipe is used.
With reference to accompanying drawing, this step-up system is in the outside of casing 1 driving gear 2 to be housed, and (small transmission gear 3 is housed in rotating shaft a) with driving gear is coaxial in casing.The first driving gear 4 that has been connected with a joggle below small transmission gear and is equipped with bevel pinion 5 on the first driving gear coaxial (rotating shaft b).Bevel pinion be connected with a joggle perpendicular to the large bevel gear 6 on the rotating shaft c of rotating shaft b, and on the large bevel gear coaxial (rotating shaft c) second small transmission gear 7 is housed.The third-largest driving gear 8 on second small transmission gear and the rotating shaft d is connected with a joggle, and on the third-largest driving gear coaxial (rotating shaft d) the 3rd small transmission gear 9 is housed.The 3rd small transmission gear and power output gearwheel 10 are connected with a joggle, and power output gearwheel is fixedlyed connected with output sleeve 11, the dynamic output leading screw 12 that in output sleeve, is connected with a joggle, and the axle sleeve 13,14 that is fixed on the casing is passed at power output leading screw two ends.Power output leading screw passes axle sleeve 14 ends and is provided with keyway 15, and key 16 is housed in keyway, and output sleeve rotates drive power output leading screw along continuous straight runs and moves.The power output leading screw the other end is provided with connecting thread 17.Be provided with pressure bearing 21 between output sleeve left end and casing.Be installed in small active gear 18 on the e axle being connected with a joggle above the driving gear.On driving gear, small active gear, be equipped with square spindle nose 19, cover assembled cranking bar 20 on square spindle nose.
The utility model designer presses the step-up system that present embodiment is implemented 240 * 280 * 150 millimeters of boundary dimension, only 42 kilograms of main frame weight.42 millimeters of small active gear diameters, the number of teeth 12, modulus 3,132 millimeters of driving gear diameters, the number of teeth 45, modulus 3,42 millimeters of small transmission gear diameters, the number of teeth 12, modulus 3; 114 millimeters of first driving gear diameters, the number of teeth 35, modulus 3,67 millimeters of bevel pinion diameters, the number of teeth 10, modulus 5; 99 millimeters of large bevel gear diameters, the number of teeth 16,49 millimeters of modulus 5, the second small transmission gear diameters, the number of teeth 12, modulus 3.5; 122.5 millimeters of the third-largest driving gear diameters, the number of teeth 33,63 millimeters of modulus 3.5, the three small transmission gear diameters, the number of teeth 12, modulus 4.5; 183 millimeters of power output gearwheel diameters, the number of teeth 40, modulus 4.5, output sleeve is that 48 millimeters of diameters, 8 millimeters square threaded forms cooperate with power output leading screw.During work, crank is enclosed within rotation small active gear or driving gear input rotatory force on the square spindle nose, when rotating small active gear during 163 weeks, power output gearwheel rotated for 1 week after gear transmission, and leading screw moves horizontally 8 millimeters.This step-up system can realize that with artificial hand rotation crank the pulling force or the pressure of power output leading screw can reach more than 100 tons.
