What is a slewing drive?

Slewing drive is a full circle rotary reduction transmission mechanism that integrates a driving power source. It uses a rotary bearing as the driving follower and mechanism attachment. By attaching an active component, driving source, and cover to one of the inner and outer rings of the rotary bearing, the other ring is used as both the driving follower and the connecting base of the driven working component. This takes advantage of the characteristic that the rotary bearing itself is a full circle rotary connector, Efficient configuration of the driving power source and main transmission components makes it a universal reduction transmission mechanism that integrates rotation, deceleration, and driving functions, while also having a simple structure and convenient manufacturing and maintenance.

According to the variable speed transmission form of slewing drive, it can be divided into gear slewing drive and worm gear slewing drive. Inheriting the respective characteristics of gear drive and worm gear Worm drive drive, these two slewing drives can respectively adapt to the applications of medium high speed and low speed. In terms of bearing capacity, the worm gear type is better than the tooth type, and when using enveloping Worm drive drive, its bearing capacity The resistance to deformation and transmission rigidity have been further improved, but the efficiency of worm gear slewing drive is inferior to that of toothed slewing drive

Characteristics of slewing drive

Slewing drive is a highly integrated full circle rotary reduction mechanism, and its characteristics go beyond that. The difference in the maximum and minimum slewing drive can drive components and loads is tens of times, but their dimensions, especially the axial dimensions of the transmission chain, are not significantly different. This is conducive to flattening the structural form of the series transmission connecting components, thereby reducing the size of the entire mechanical equipment.
In addition, whether it is a tooth type or a worm gear worm type slewing drive, due to the large size difference between the driving and driven parts themselves, it is easier to achieve high transmission ratio transmission, which is also difficult for many other types of variable speed transmission mechanisms to achieve.

Advantages of slewing drive

• Modularization
  Due to the high integration of the slewing drive, users do not have to purchase and process each component of the rotating device one by one, which to some extent reduces the preparation process at the beginning of product production and greatly improves labor productivity.

• Security
  Worm gear Worm drive has the characteristics of reverse self-locking, which can realize reverse self-locking, that is, only the worm can drive the worm gear, but not the worm gear. This feature makes the slewing drive widely used in lifting, aerial work and other equipment. While improving the scientific and technological content of the host, it also greatly improves the operating stability and Factor of safety of the host. Compared with traditional rotary products, slewing drives have the advantages of simple installation, easy maintenance, and greater space savings.

• Simplify host design
  Compared with the traditional gear drive, the worm gear Worm drive can obtain a relatively large reduction ratio. In some cases, it can save the reducer parts for the host, thus reducing the purchase cost for customers, and also greatly reducing the failure rate of the host.

Applications of  Slewing Drive

• High altitude work platforms

• Fire truck ladder

• Marine crane

• Log transfer machine
