EG Series Slewing Drive

回转传动是齿轮箱处理径向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.
