What and how ? Hydromotors for the rotation of smaller construction machines are much less complex than those of larger models. There are two most popular types of hydraulic motors used to drive the rotation of smaller construction machines. These are piston and rotary engines, so-called “rotators”. How do you recognize if the swing motor
Due to the influx of a large number of driving engines of construction machinery other than excavators. I decided in a short article to describe their principle of operation and whether it can be properly regenerated. So to restore their efficiency at a much lower price than associated with the purchase of a new engine.
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
Did you forget Many owners, operators of mini diggers forget about servicing their machines in the winter. In 99% of cases, smaller mini diggers are not as necessary to work as in the summer because they are not strong enough to overcome the permafrost layer, so remember that that winter is the only time when
Planetary gear: What is it and what is it for? Travel final drive planetary gear is a drive wheel that is used in planetary propulsion transmissions. Depending on the construction, there are: one, two or three rows of satellites (driving gears). Each row has 2 to 5 gears. Rows of satellites are counted from the
Rental of construction machinery is an extremely popular alternative. It pays off for both private individuals and companies. Buying a construction machine is really a great investment, and of course it doesn’t end with the purchase. The machine must be maintained, stored somewhere, and above all, remember about its servicing and the replacement of operating
Angular contact bearings and axle regeneration. Why are they mounted in gears? What and how? Very often, angular bearings – asymmetrical are installed in driving gears. They differ mainly from ordinary bearings by the asymmetrical position of the outer race relative to the inner bearing. This is to increase the running surface while occupying a
Tracked vehicles require the use of effective protection for the bearings of running, support and returnable rollers, hubs or axles of wheel drives against the penetration of dust, sand, mud, stones or soil. In other words, a sliding seal is a metal sealing of the reducer, which aims to maintain the tightness of the hydromotor
The drive motor shaft is an element of the excavator driving hydromotor drive system. Transmits the drive directly from the engine piston pump to the final drive where it connects with the final drive shaft. These two gear shafts are a great duo! Driving motor shaft The motor shaft has two multi-key teeth along its
Are you looking for travel gearbox parts? Do you want to know how to look for them effectively? In this article we will show you how to search for parts not only for excavator final drive but also for other machines using planetary or cycloidal drive. Did your planetary gear get broken? Hydromotor drive or
