ABSTRACT
This type of ZL15 loader that I have designed has the common virtues of the traditional loaders.And it has some new-improved virtues and function.
In my design progress,I put emphasis on the gearbox design. The ZL15 loader belongs to pint-size earthmoving machine.It is suitable for the construction site, the freight yard and so on, where the bulk materials are placed. Other more, it can dig and level lightly.
ZL15 loader belongs to ZL series, using wheeled walking system, hydro mechanical drive, articulated car frame, so the loader has many advantages, such as good maneuverability、turning agility、high productivity、operate portability, and so on. In addition, setting the latter bridge as Swing Bridge increases the overall stability and the safety of the machine.
The ZL15 loader is adopted fixed-axis gear-box, which can simplifies the structure of the whole machine, lowers production costs and make it easier for general service. In the design, after referring to the same type machine, the best transmission scheme is adopted finally, which can minimize the number of the parts and makes the machine has reasonable transmission ratio, so as to satisfy the demand of operation. The fixed-axis gear-box adopts dynamic gear-shifting, which makes the operation of the cab handier, and reduces the intensity of labor.
Gearbox design, including: the choice of transmission type, to determine the final drive ratio, transmission schematic design (three after three stalls), all gears with teeth, Ⅰaxis and Ⅱaxis clutch design, structural design (including the axis , the choice of bearings and gears check prices). Finally I use CATIA to analyze the stress situation of the output axis.
