FGE Series FGE25 Slewing Drive Gearbox For Excavator Accessories
Excavator accessories (swing drive gearbox)
The rotary drive gearbox is not only used for excavators but also a variety of mobile cranes. These transmissions have different capacities and can be equipped with negative brakes. They can also be installed with slewing ring and pinion transmission, and different types of slewing pinion are available.
Hourglass worm profile
The hourglass worm profile provides higher gear function and durability for the rotary drive gearbox. It has 11 teeth in contact with the worm shaft simultaneously, making it more robust, durable, and efficient than the traditional worm gear. It is also suitable for applications requiring precise positioning of workpieces, such as metal cutting and forming. Its low backlash ensures high precision results.
Hourglass worm has many advantages, including low maintenance and better component protection. The ever-power FGE series has an IP55-rated housing, integrated mounting flange, and hourglass worm technology. These gearboxes can be installed vertically or horizontally and have a range of mounting configurations.
The swing drive gearbox has various capacities and models. Some models have dual axis drive functions and can be used for dual axis. Others are designed for heavy-duty applications with double-row slewing bearings.
Double row slewing bearing
Slewing bearing is made of chrome steel or GCr15SiMn, which is used for slewing drive gearbox of the excavator. They are usually sealed with nitrile rubber or iron and packed in wooden cases. Ever power provides these slewing bearings for various excavator brands, including Komatsu and Kobelco. If you need to replace the slewing bearing, you should look for a reputable supplier who can provide slewing bearings of the same model, brand, and model.
The slewing ring on the excavator is a crucial component hidden deep in the machine. Bearing failure in this critical component may result in inefficient machine movement. Severe wear of the slewing ring will also affect the whole machine. To obtain the best performance, the slewing bearing must resist the inevitable wear during use.
Slewing bearing combines traditional bearing elements, including gears, mounting holes, and lubrication, to smooth the rotation of heavy parts. The horizontally installed slewing bearing is used for the slewing drive gearbox of the excavator. The slewing bearing can be installed on the frame and chassis of the excavator. The double-row slewing bearing provides 360-degree rotation.

Application
hzpt slewing drive is a gearbox designed to handle radial or axial loads using high rotational torque. In addition, the slewing ring bearing, at the heart of the drive, enables it to withstand high overhung or moment loads. A descendant of the "worm" screw, slewing drives are present in construction machinery, manufacturing, equipment, and many other applications that require strength and precision.
The physics of the slew drive makes it a versatile solution for many applications. In operation, the slew drive's axial movement, or motion around its axis, interacts to create radial torque. The action occurs by meshing the grooves of the horizontal screw with the teeth of a perpendicular gear. While turning, the worm gear's axial movement transfers magnified torque force to the radial gear. The number of threads on the horizontal screw and the number of gears that interact will determine the speed ratio of the setup.
Slewing drives are available in many configurations depending on the task at hand. These may be single-axis or dual-axis turning in unison.
