Background technique
Total institute is known, and gearbox is a kind of deceleration, a kind of mechanical transmission that increases moment.Generally, a speed changer drives a working machine job, in the time that two working machines on a machine are worked, just needs two speed changers to drive, and takies large quantity space, and difficulty is arranged in the space that has increased speed changer, and cost increases thereupon.If when space does not allow two speed changers to occur, this operation just cannot complete simultaneously.
Differential roller sheller unit is exactly this series products, and in process, there are the following problems installing and using: the man-to-man layout of speed changer and working machine, take space, and difficulty is arranged in the space that has increased speed changer, and cost increases thereupon; In particular cases, space does not also allow to occur many speed changers simultaneously.For this reason, many manufacturers and research institution have all carried out R and D, but do not have so far desirable product to emerge.
Summary of the invention
For overcoming the existing above-mentioned deficiency of existing speed changer, the object of the invention be to provide a kind of simple and reasonable, easy to install, transmission is effective, have two power speed changer of coaxial differential in the same way of coaxial differential output in the same way.
The invention solves the problems of the technologies described above adopted technological scheme, it comprises gearbox casing, drive input shaft, transition axis, driver output axle, described driving input shaft and driver output axle are vertically set on gearbox casing mutually, transition axis and driver output axle are arranged in parallel on gearbox casing, drive input shaft to be provided with the first bevel gear, one side correspondence of driver output axle is provided with the second bevel gear and the second cylindrical gears, the opposite side of driver output axle is provided with the Cylinder Gear wheel shaft that can mutually rotate, on transition axis, correspondence is provided with first and three cylindrical gear, the first bevel gear engages with the second bevel gear, the second cylindrical gears engages with three cylindrical gear, the first cylindrical gears engages with Cylinder Gear wheel shaft, driver output axle and Cylinder Gear wheel shaft rotating Vortex, drive input shaft to input a power, the coaxial output of driver output axle and Cylinder Gear wheel shaft two power.
The further scheme of the invention, described Cylinder Gear wheel shaft is arranged on rotationally on gearbox casing and by inner bearing and is coaxially arranged on driver output axle by outer bearing.
The further scheme of the invention, the rotating speed of described driver output axle is greater than the rotating speed of Cylinder Gear wheel shaft.
The further scheme of the invention, the corresponding outside framework oil seal that is provided with between described Cylinder Gear wheel shaft and gearbox casing and between driver output axle and Cylinder Gear wheel shaft.
The further scheme of the invention, is marked with lubricant oil in described casing.
Adopt after said structure, have the following advantages compared with the prior art and effect: in the time driving a power of input shaft input, the driver output axle of clutch end and Cylinder Gear wheel shaft are exported two power of differential in the same way, coaxial differential gearbox arrangement is in working machine one end in the same way, can realize two working machines works simultaneously, and coaxial differential rotation in the same way, compact structure, transmission efficiency is high, volume is little, good airproof performance can be used for severe working environment, and the coaxial in the same way output of speed changer power makes working machine more steadily reliable in the time of work.
