Slewing Drive - Overview

A slew drive is a compact, robust, and complete rotary system that integrates a slewing ring bearing, a worm gear, and a sealed housing to provide smooth, controlled rotation for heavy loads in various applications like cranes, construction equipment, and solar trackers. It translates rotational motion from the worm gear to a perpendicular worm wheel, increasing torque and providing high holding torque to safely support radial and axial loads without needing a separate brake.

Application

The field of beam transport vehicles
The core components of the traditional beam truck slewing assembly mostly use traditional slewing ring products. Compared with the slewing drive, the slewing ring does not have an outer shell, and the corrosion resistance is not ideal, and hydraulic cylinders are used to drive the steering of the tires. In terms of the system, the rotation angle range of the tire is also greatly restricted. The selection of a slewing drive device as a slewing component can not only improve the corrosion resistance of the component, but also increase the steering angle of each group of tires.

The field of aerial work vehicles
Aerial work trucks are an important application area of slewing drive. Generally, high-altitude work trucks require the host to have a higher safety factor. The high safety of slewing drive (self-locking of worm gears) is the majority of users choose it as an aerial work platform accessory On the other hand, the worm gear transmission has a larger transmission speed ratio, so that while improving the safety factor of the main engine, a set of worm gear reducers can also be omitted for the main engine, thereby reducing the manufacturing cost of the main engine.

The field of photovoltaic power generation
Photovoltaic power generation is an important application field of slewing drive. Solar photovoltaic modules with slewing drive as a rotating part can accurately adjust the rotation and elevation angle of the host according to the different positions of the sun during the day. The solar panels are always in good condition. Receiving angle.

Wind power generation
Similar to photovoltaic power generation, the slewing drive can be applied to the yaw part of the wind generator to realize the horizontal 360° rotation of the mechanism, so as to better adjust the receiving angle.

The field of construction machinery claws
Construction machinery auxiliary equipment is a new application field of slewing drive. The slewing drive is used as the claw of the rotating mechanism, which makes the design structure more concise, which is more conducive to use and maintenance. At the same time, the worm gear drive has a larger reduction ratio, which makes the claws, etc. The positioning accuracy of construction machinery aids has also been greatly improved.

The field of industrial robots
Due to the compact structure and short transmission chain, the slewing drive is easier to achieve higher accuracy and easier to carry out digital control, so it is also widely used in the field of industrial robots. Recently, robots derived from AGV (mobile robots), spot welding robots, welding robots, arc welding robots, laser processing robots, vacuum robots, clean robots and other varieties have slewing drive applications.

Structure of Slewing Drive

Slewing drive usually consists of two parts: slewing support and slewing drive. The slewing support device is used to connect the slewing part of the crane with the non-slewing part, and to provide the constraints required by slewing movement to ensure that the slewing part has certain movement. At the same time, it provides a stable support for the slewing part to withstand the vertical load, horizontal load and overturning moment from the slewing part.The rotary drive device is used to drive the rotary part relative to the non-rotary part to realize the rotary movement.

In order to ensure the reliable operation of the rotating machinery and prevent overload, it is generally necessary to install a limit torque limiter in the transmission system.Most active machines use electric motors, but most mobile slewing cranes use internal combustion engines.Most of the rotary driving elements use gear (or needle wheel), but some cranes use driving roller or rope traction.

According to the use and construction of the crane, the rotary drive device can be arranged in two ways:
The slewing drive is mounted on the slewing part of the crane, and the last stage of the large gear ring (or needle wheel) is mounted on the rack of the non-slewing part. In the slewing mechanism of the port crane, this form is adopted in most cases.

Slewing drive is mounted on the non-slewing part of the crane, and the last stage of the large gear ring (or needle wheel) is mounted on the slewing part of the crane, which is sometimes used in some large fixed column cranes and tower cranes.

FAQ

Q: How to mount a slewing bearing?

A: When installing the slewing bearing (turntable bearing), first we should make the radial-positioning ,the mounting bolts should be cross-tightened. And the swing of the slewing bearing should be checked. To ensure a smooth bearing drive, the gears should be engaged before the mounting bolts are tightened.

Q: What are slew drives used for?

A: Slew drives are often used in industrial turntables to rotate and position large or heavy items. These turntables are used in various manufacturing processes and need to provide precise control. Slew drives enable accurate rotation and positioning, which is essential for the efficiency of production lines.

Q: What is the efficiency of slew drive?

A: Typical slew drive efficiency is about 30%.
