The principle of the parallel heterodromous double-output gearbox is as follows: it is rotatory to drive the countershaft through the input shaft, because this countershaft is the unipolar so that turning to at both ends the same, and output shaft one and output shaft two that are connected respectively with the countershaft both ends then be mutual reverse rotation, it is further, this gear box forms fixedly with the cylindric lock through designing into the components of a whole that can function independently with the spline housing connection with the countershaft both ends, consequently, be convenient for dismantle the maintenance alone of left box and right box, do not influence the main tank body at the dismantlement in-process, and its connection structure is comparatively simple, extract cylindric lock alright direct separation, the dismantlement time of later stage gear box maintenance has been shortened greatly, required extracting tool is also less, whole practicality has been increased.
In the parallel heterodromous double-output gearbox, the two side walls of the main box body are respectively clamped with bearings for supporting the auxiliary shaft, the end surface of one bearing is abutted against the bevel gear and is fixed by arranging the clamping ring, and the other bearing is directly fixed by the clamping ring.
In the parallel heterodromous double-output gearbox, the main box body is split, one side of the main box body is sealed by the box cover, and one bearing is clamped in the box cover.
In the parallel heterodromous dual-output gearbox, the top of the main box body is provided with the access cover which is made of plastic and is fixed with the main box body in an interference fit manner.
In foretell parallel incorgruous dual output gear box, the outside of left side box and right box all is linked firmly the apron through the screw.
In the parallel heterodromous double-output gearbox, the spline sleeves are provided with grease nipples.
In the parallel heterodromous double-output gear box, the input shaft, the first output shaft and the second output shaft are mutually parallel, and the output ends of the first output shaft and the second output shaft are positioned on the same side.
In the parallel heterodromous double-output gear box, the output ends of the first output shaft and the second output shaft are respectively provided with a circle of limiting steps of an integrated structure.
Compared with the prior art, the parallel heterodromous dual-output gearbox has the advantages of being more convenient to disassemble and maintain in the later period by designing the two ends of the auxiliary shaft into split structures and connecting the split structures through the spline sleeve and the cylindrical pin, and is simple in connecting structure and low in manufacturing cost.
