IMPROVED DESIGN OF THE TRACKED
TRACTOR TRANSMISSION
ABSTRACT
This article describes in detail the design of this content and design ideas. The
design is mainly in the DFH 1302R prototype on the basis of the analysis improvements,
focus on the prototype design deficiencies and the problems. Analysis of crawler tractor
in the work environment and agriculture operations on the basis of a re-arrangement of
the distribution of transmission ratio, manipulation of the optimization, and improving
the mode of engagement are done, such as increasing the scope of the transmission ratio,
increasing a low-speed operation block, and the favorable environment for plex,
shifting the original style of direct pull shift into gear meshing sets shift, shifting more
convenient and reliable. In order to prevent tooth playing with greater impact and
improve the tractor started in suit performance of the dual role of the structure of the
clutch, the output power and transmission shaft in different light moment, and
combining the features were in agricultural production is very necessary.
For structural design pact three-axis, it can meet pact structure,
material savings. For gear settings, as far as possible to save space, a reasonable layout
is done. Using contour shape of a large number of circular arc transitions so that the
casting performance enhancement, reasonable structure, pleasing in appearance.
Agricultural mechanization in the number of such gear today, with the development an
