14 Inches Big Hydraulic Slew Drive For Cranes And Construction Machines
Hydraulic Slew Drive Description
1. Tooth type: Helical tooth
2. Bearing load: light load
3. Drive type: Motor drive
4. Module: 5/3.75
5. Number of worm shafts: 1
6. Gear Ratio: 85: 1
7. Efficiency: 40%
8. Self-locking gears: YES
9 Weight: 63 kg
Tilting Moment Torque: This torque is the gravity load multiplied by distance between the position of load and the center of slewing bearing. If the actual torque is greater than the rated tilting moment torque, slewing drive will be overturned.
Radial load: The load vertical to the axis of slewing bearing
Axial load: The load parallel to the axis of slewing bearing
Holding torque: It is the reverse torque.When the drive is rotating reversely, and parts are not damaged,The maximum torque achieved is called holding torque, it is also seen as broken torque.
Self-locking: Only when there is load, the slewing drive is not able to reverse rotate and thus called self-locking.
