Slew Drive

A VE (Vertical-Enveloping) Slew Drive, often referred to as a vertical-mounted slew drive, is a type of slewing drive mechanism designed to provide high torque transmission, precise rotation control, and low backlash. The VE Slew Drive typically consists of a vertical shaft with an attached worm gear, a slewing ring bearing with external or internal gearing, and the worm gear's mating pinion.

Features of Vertical Mounted Slew Drive:

High Torque Transmission: VE Slew Drives deliver high torque output, enabling the efficient and controlled rotation of heavy loads.

Compact Design: The vertical arrangement of the worm gear mechanism allows for a compact size, making it suitable for applications with limited mounting space.

Precision Rotation Control: The VE Slew Drive offers precise rotation control, providing exact positioning for various applications where rotational accuracy is essential.

Low Backlash: The enveloping design of the worm gear ensures low backlash, which contributes to smoother operation, fewer vibrations, and longer lifespan.

Self-locking Capability: The worm gear in the VE Slew Drive has a high gear reduction ratio and often features self-locking properties, preventing the driven load from rotating uncontrollably and enhancing safety.

Applications of VE Slew Drive:

VE Slew Drives are used in a variety of industrial applications, such as:

Solar trackers: For single-axis and dual-axis solar tracking systems, helping to optimize the collection of solar energy by allowing solar panels or mirrors to follow the sun's path.

Cranes: Providing controlled rotation and stability in heavy lifting cranes or mobile cranes.

Wind turbines: Used in yaw and pitch control systems for optimal orientation against the wind and protecting the equipment from excessive forces.

Excavators and heavy machinery: Providing robust and precise rotation control for heavy equipment, such as excavators, tunnel boring machines, and drilling rigs.

Robotics and automation: Used in applications requiring high precision and high torque transmission for controlled movements.

Price of VE Slew Drive:

The cost of a VE Slew Drive can vary significantly depending on factors like size, load capacity, torque transmission capabilities, material, and manufacturer. Generally, prices can range from a few hundred to several thousand dollars. To get the most accurate and up-to-date pricing for specific VE Slew Drive models, it is recommended to consult with manufacturers or distributors who can provide quotes based on your application requirements and specifications.
