Planetary gear and its application – FHU SOJKA

The use of planetary gears in other construction machinery.

The planetary drive train is used in a very wide range of construction machinery. In principle, all machines moving on caterpillars are driven by a hydromotor transmitting power to the planetary gear. In our opinion, these types of gearboxes are the best way to change the drive speed of tracked machines. Their great advantage is that they are virtually indestructible. Remember to control the oil level in gears, bearing in mind that it does not necessarily have to leak. Gear oil tends to develop quickly. That is why we recommend that it be monitored at least every 100 hours. We should also remember to monitor the condition of gear seals. It should be checked that there are no signs of “sweating” at the connection point between the gear unit and the engine or the frame. This is the first sign that gearbox seals are damaged.

By following these recommendations, you will minimize the probability of transmission failure to a minimum. Returning to the planetary gear applications. This year, we’ve already received a lot of devices from unusual machines, such as: a plum harvester, scissor lift, a robot used to detonate explosives, a remote-controlled micro-excavator and several others.

For example, the transmission in Dutch scissor lifts resembles the transmission used in Polish HSW bulldozers combined with the Linde forklift truck motor. However, I note that they only remind – because they are not identical, which would greatly simplify the matter. As you can see planetary gears are extremely popular among a wide range of construction machinery.
