Slewing drive

The slewing drive is a gearbox that can safely hold radial and axial loads, as well as transmit a torque for rotating. The rotation can be in a single axis, or in multiple axes together. Slewing drives are made by manufacturing gearing, bearings, seals, housing, motor and other auxiliary components and assembling them into a finished gearbox.

History
The slewing drive is a modernized take on the worm drive mechanism that dates back many centuries and was widely used during the Renaissance Era. Pappus of Alexandria (3rd century AD), a Greek mathematician is credited for an early version of the endless screw, which would later evolve into the worm drive. This mechanism was also used by Leonardo da Vinci as a component in many of his designs for machines. It can also be found in the notebooks of Francesco di Giorgio of Siena.
Many slewing drive concepts found prominence with the emergence of larger scale construction and engineering in the height of the Greek and Roman Empires.
Technology
Slewing drives function with standard worm technology, in which the worm on the horizontal shaft acts as the driver for the gear. The rotation of the horizontal screw turns a gear about an axis perpendicular to the screw axis. This combination reduces the speed of the driven member and also multiplies its torque; increasing it proportionally as the speed decreases. The speed ratio of shafts depends upon the relation of the number of threads on the worm to the number of teeth in the worm wheel or gear.

As technology has improved, more slewing drives are using hourglass worm technology, in which the worm is shaped to engage more teeth in the gear.This increased tooth engagement results in greater strength, efficiency and durability.

 

Performance characteristics

Because of their multiple uses, slewing drives come in a variety of model sizes, performance ranges and mounting characteristics. The drives are well suited for applications that require both load holding and rotational torque from the same gear box. They can also be made with dual axes of rotation, (turning axes at the same time) or with dual drives on the same axis, (two worm threads driving the same ring gear in one axis).

 

Materials

The specifications for drives and gears varies depending on the material the gear is composed of. However, a majority of the drives and gears commonly used are composed of steel and phosphor bronze. According to an extensive series of tests by the Hamilton Gear & Machine Co., chill-cast nickel-phosphor bronze ranked first in resistance to wear and deformation.

SE-2 Series slewing drives, slew drives are combined by housing, slewing ring, two hourglass worm and some matching parts,it achieved 2 times of tooth contacting. In the same volume and installation spave, it improved nearly double output torque, greatly improving the product's performance.

 

Note
1. Different motors (AC,DC,Hydraulic) can be designed according to customer's requirement.
2. Shaft opposite to motor can choose to be hex head or not hex head.

 

WEA series slewing drive,slew drive is a new series of slewing product, also named as slewing reducer. It is commonly composed of worm,slewing bearing, housing, motor adapter, end cap and other components. By adopting slewing bearing as its core component, slewing drive can bear axial force, radial force and tilting moment simultaneously. Comparing with SE series slewing drive, WEA series have the advantages

of better protective performance, great transmission torque, better impact resistance and long working life.

WEA series slewing drive is widely applied in the relatively rotary parts of machinery and solar energy field. Solar tracking system Rotary chassis

of aerial working machinery Truck crane Rock drill, drilling machine Grasping wood machine, code molding machine.

 

Open Housing Slewing Drive Dual Worm

 

Opening house dual worm slewing drive's structure make it run more smoothly, mainly apply to the application with high output torque but limited mounting space. It can be use for not high working condition requirement for dust proof, rain-proof and anti-corrosion occasion. Precision grade IP65.

 

Special Slewing Drive Vertical Type

VE means vertical installation slewing drive, mainly apply to the high working condition requirement for dust proof, rain-proof and anti-corrosion occasion. Precision grade IP65.
The Slewing Drive can be used for any occasion where the need for full-cycle rotation and variable speed requirements. When the need for larger torque power transmission, the higher accuracy of the motion transmission or the compact structure of the body requires a higher mechanism selection, the rotary drive Is the best solution.Enclosed dual axis slewing drive can realize the movement in two different direction,vertically and horizontally. Usually apply to the dual axis solar tracking systems or some machinery equipment with similar working condition.

 

Electric and planetary gearboxes of Special Slewing Drive Dual Axis can be designed according to customer requirements. Rotary drives have the advantage of saving equipment space, maximum load capacity, compact design, extensive servicelife and reduced maintenance costs.

 

Note:

1) Tilt Torque: The load is multiplied by the distance between the load position and the center of the rotary support. If the torque

generated by the load and distance is greater than the rated tilting moment torque, the rotary drive will be reversed.
2) Axial load: parallel to the slewing bearing
3) Radial load: perpendicular to the slewing bearing
4) self-locking: only when the load, the rotary drive can not reverse rotation, so called self-locking.
5) Hold torque: Reverse torque. When the drive is rotated backwards, the parts are not damaged
6) The maximum torque achieved is called the holding torque.

 

Slew Drive Gear Reducers

• Tilting Moment Torque:

Torque is the load multiplied by the distance between the position of load and the center of slewing ring. If the torque generated by load and distance is greater than the rated Tilting Moment Torque, slewing drive will be overturned

• Holding Torque:

It is the reverse torque. When the drive is rotating reversely, and parts are not damaged, the maximum torque archived is called Holding Torque.

• Axial Load: Load parallel to the axis of slewing ring.

• Radial Load: Load vertical to the axis of slewing ring.

• Self Locking: When loaded, the slewing drive can not reverse rotation and thus called self-locking Slewing Bearings
