The Bonfiglioli company has been operating since 1956 and provides propulsion technology solutions for many industries. Currently, it is a modern, international group, as well as one of the leaders in the drive industry. Travel drives for tracked machines are also very popular. /Bonfiglioli travel final drive/
The design of Bonfiglioli products is always carried out using the latest available methods. The production of all transmission components takes place on fully automated production lines, which allows obtaining the highest level of quality of finished products. Thanks to all these factors, Bonfiglioli customers have access to compact, light and quiet-running machine drives that are widely recognized around the world.
Bonfiglioli travel final drive
In other words travel final drive is a planetary gear or travel gearbox. 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.
Bonfiglioli travel final drives are characterized by high efficiency, including high torque in a small space. The brand supplies 700CK and 700CP series drive drives. Torque range of the 700CK series is between 1,200 and 220,000 Nm. The gear range is between 20 and 120. The reducers of this series are used in tracked machines weighing from 1.5 tonnes to 70 tonnes. 700CP series has drives with a torque of 1,200 to 5,000 Nm, while the gear ratio is 18.5 to 57.5. 700CP series is used in mini excavators with a weight range of 1-6 tons. Lightweight, efficient and smooth to operate, 700CK Series track drives are powered by integrated axial piston hydraulic motors, developed in cooperation with Kayaba. The 700CP series was developed in cooperation with Poclain Hydraulics.
Travel final drive advantages
Planetary gears are very popular because they allow you to freely chenge speed and rotation force. They are used especially in those machines that operate at high turns and are small overall dimensions. Their adventage is the mulitpoint drive transport. Thanks to which individual teeth in the toothed wheels are exposed to lower load. This affects the life of the planetary gear.
For years the use of planetary gearbox is the best method of drive transfer in tracked machines.
