Caterpillar 374D 374F Final Drive Travel Motor 513-0834

In other words /513-0834/ travel final drive or travel gearbox is a planetary gear. It is applicable to all machines that run on caterpillar tracks. In excavators, there are always two travel gearbox, far apart from each other, not forming a compact structure. They are mainly used to increase the torque and thus reduce the speed on the tracks.

In /513-0834/ travel final drive transmission is carried out using interlocking gears. Depending on the construction of the planetary gear we can distinguish the reduction sets of the first, second and third order.

The operation of the planetary gear is quite often compared to the solar system, as the name itself suggests. The mechanism of action can be described as follows: In the centre of the planetary gear there is a sun wheel and the others elements are circling around it like planets. When gears

rotate around their own axis, the energy is divided into individual satellite wheels inside carrier assy. These wheels transmit the energy to the next elements of the system.
