eg series slewing drive

A slewing drive is a gearbox that handles radial or axial loads with high rotational torque. In addition, the slewing ring bearing at the heart of the drive enables it to withstand high cantilever or moment loads. A descendant of the “worm” lead screw, slewing drives are found in construction machinery, manufacturing, military equipment, and many other applications where strength and precision are required.

A slewing drive is a gearbox that handles radial or axial loads with high rotational torque. In addition, the slewing ring bearing at the heart of the drive enables it to withstand high cantilever or moment loads. A descendant of the "worm" lead screw, slewing drives are found in construction machinery, manufacturing, military equipment, and many other applications where strength and precision are required.

Slewing drives are available in many configurations depending on the task at hand. These may be single-axis or dual-axis turning in unison.

An hourglass configuration expands the capability from a single gear tooth to as many as 11 to create rotational torque by contacting the worm screw. Multiple gear teeth interacting at once allows the equipment to be more efficient and generate more torque.

Slew drives work best for applications in which high torque can create precision positioning and rotational accuracy. This design results in a device that works smoothly and powerfully with minimal backlash.

Because of the power and dependability generated by slew drive technology, the functions of this engineering technology apply to many types of equipment. One particular use, for example, involves solar technology, tracking the sun’s movements in perfect time to generate maximum energy output.

Application Case

Slewing drives are best suited for applications where high torque can produce precise positioning and rotational accuracy. This design results in a smooth working, powerful device with minimal backlash.

The list of active applications for slew drives is extensive. Several types of industries require some form of slewing drive to improve the efficiency of their operations. Mining, construction, metalworking, and other applications that require unrelenting strength and flawless precision use rotary technology for safety and accuracy.

Powerful equipment such as aerial lifts, rotary forklifts, truck-mounted cranes, cable winders, fire trucks, hydraulic machinery, and utility equipment depends on the safety and strength of slewing drives. Precision equipment such as military equipment, satellite dishes, solar trackers, printing presses, and telescopic devices benefit from the adequate precision offered by slewing drives.
