The article gives a method of selecting gear transmission for the implementation
of the working stroke (logging) tracked skidder, taking into account the real characteristics motor-transmission setting, natural production conditions (slipping, rolling
resistance, the volume of packets), and normal distribution of traction resistance in
specific fixed conditions operation. Calculated criteria for selecting gear ratios, how
and why they vary and affect performance. The cycle of the skidder consists of four
main elements: a set of packs, cargo shift (skidding), reset packets, idling. The most
energy-intensive and loaded a cargo move, the effectiveness of the implementation
97
of which requires the implementation of a maximum cardinality towing machine parameters. Providing this condition is associated with the optimal choice of gear
transmissions. In previously published papers on the choice of gear ratios and industrial timber tractors often do not take into account such features of the skidders as:
the impact of traction hook on the work of the tractor, the impact of slippage is taken
into account only the limit of adhesion, but does not take into account the effect of
slippage on the actual speed and power of the tractor in the process of logging, and
do not always take into account the real nature of the load (resistance to change in
traction) skidder when performing the working stroke. In our opinion, as the performance criteria can serve as the value of average power and average speed (which under these conditions ensures maximum transport capacity). As an auxiliary criterion
can be taken the average specific fuel consumption and average unit cost of fuel per
unit of cargo.
