EWA7 Series Slewing Drive

Slewing drives are created by manufacturing gearing, bearings, seals, housing, and motor along with other auxiliary elements and assembling them into a finished gearbox. The slewing drive is usually a gearbox that will safely hold radial and axial loads, together with transmitting torque for rotating. The rotation can be within a single axis or in several axes together.

Slewing drives are created by manufacturing gearing, bearings, seals, housing, and motor along with other auxiliary elements and assembling them into a finished gearbox. The slewing drive is usually a gearbox that will safely hold radial and axial loads, together with transmitting torque for rotating. The rotation can be within a single axis or in several axes together.

Slewing drives perform with regular worm technology, by which the worm around the horizontal shaft acts as the driver for the gear. The rotation of the flat screw turns a gear about an axis perpendicular to the screw axis. This blend lowers the pace with the driven member and multiplies its torque, expanding it proportionally as the velocity decreases. The speed ratio of shafts depends upon the relation between the variety of threads on the worm on the array of teeth inside the worm wheel or gear.

As technological innovation has improved, additional slewing drives are working with hourglass worm technological innovation, through which the worm is shaped to engage much more teeth during the gear. This enhanced tooth engagement leads to higher strength, efficiency, and sturdiness.

Due to their various uses, slewing drives can be found in many different model sizes, effectiveness ranges, and mounting characteristics. The drives are well suited for applications requiring each load holding and rotational torque from the same gearbox. They can also be manufactured with dual axes of rotation (turning axes simultaneously) or dual drives around the same axis (two worm threads driving the identical ring gear in one particular axis).

Typical Slewing Drive Applications

There are many applications in which the slewing drive can be utilized, primarily because it is perfect for applications that require both load-holding power and rotational torque strength. Typical slewing drive applications include but are not limited to:

  • Solar Trackers
  • Wind Turbines
  • Man Lifts
  • Hydraulic Machinery
  • Telescopic Handlers
  • Digger Derricks
  • Lifts
  • Cranes
  • Drilling equipment
  • Military Equipment

Company Profile

In line with honest management and customer service, the company is constantly committed to researching and developing new technologies and machines for double-worm slewing drives, small slewing drives, large slewing drives, and slewing bearings. Alternatives. We specialize in creating our brand with many experienced terms and top-notch equipment. The products are exported to Europe, America, Australia, St. Petersburg, Bahamas, Peru, Sydney, and other regions, and the products are sold worldwide. We hope to establish a long-term cooperative relationship with all customers and hope that we can improve our competitiveness and achieve a win-win situation with our customers. We sincerely welcome customers from all over the world to contact us with any need! Welcome domestic and foreign customers to visit our factory.

Due to the practical design, accurate detail processing and dimension, and one-time assembly, the product meets the customer's requirements. The slewing drive is very flexible. No noise, perfect overall accuracy, the center distance cannot be adjusted during the rotary drive assembly, the matching size requirements are relatively strict, and the matching size must be strictly controlled during the design and processing process. Otherwise, problems will arise during the assembly process and be difficult to resolve.

Our slewing drives are available in a large variety of standard design sizes. We will gladly develop a slew drive tailored to your requirements if you are looking for an individual solution.
