EGE12 Series Slewing Drive
A slewing drive is usually considered a gearbox since the core moving parts would be the slewing bearing plus the worm shaft. Because the core element could be the slewing bearing drive, the slewing gearbox can easily withstand axial and radial forces. Additionally, it consists of auxiliary components, including seals, housings, and motors. The motor drives the welding principle of slewing drive to drive the outer ring from the slewing bearing to rotate; the outer ring outputs torque by way of the flange, and the inner circle of your slewing bearing is fixed in the housing.
A slewing drive is usually considered a gearbox since the core moving parts would be the slewing bearing plus the worm shaft. Because the core element could be the slewing bearing drive, the slewing gearbox can easily withstand axial and radial forces. Additionally, it consists of auxiliary components, including seals, housings, and motors. The rotary motor is usually a DC planetary gear or an AC gear motor as an energy supply. AC hydraulic motors are primarily employed in construction machinery as a power drive technique. The motor drives the welding principle of slewing drive to drive the outer ring from the slewing bearing to rotate; the outer ring outputs torque by way of the flange, and the inner circle of your slewing bearing is fixed in the housing.
Since the worm gear drive has the reverse self-locking function, the slewing drive has the reverse self-locking function. This function significantly improves the stability and security element of the host operation. Compared with conventional slewing merchandise, the slewing drive gearbox is easy to set up, uncomplicated to keep and saves considerable installation space.

FAQ About Slew Drives
1. What is the prime mover for slew drive?
A: An electric or hydraulic motor is the prime mover for slew drive.
2. Does slew drive requires a brake or not?
A: Slew drive is used for any machine having turning movement. Usually, it is used with slew bearings with internal or external teeth, and the gearbox has a pinion on the output shaft that drives the big gear of the slew bearing.
4. What type of gearbox is used in slew drive?
A: Planetary gearbox is used in slew drive.
5: What kind of braking arrangement is provided for slew drive?
A: Normally, slew drives are electric or hydraulic. The electric type has got shoe type brake or Negative electromagnetic brake on the motor. At the same time, the hydraulic type has got a multidisc hydraulic brake.
6. What type of bearings are used in this slew drive?
A: Normally, the slew drive has a pinion with a corrected profile to ensure a complete contact pattern with bearing gear.
A: To adjust the backlash between the pinion and slew gear, the gearbox's mounting is slightly eccentric to adjust the backlash precisely.
