The difference between WEA slew drive and SE slew drive

SE Series slew drive is helical gear type, and WEA Series slew drive is turbine type. They play an important role in production. Many industries are inSEparable. I believe many people have this question. What are their respective advantages? What's the difference? This article has carried on the summary for you, believed that after reading, you will understand this more.

1.SE Series slew drive (helical gear)

2.WEA Series slew drive (worm gear)

3.Advantages and disadvantages of SE Series slew drive and WEA Series slew drive

1.SE Series slew drive (helical gear)            

SE Series is fence type slew drive. Rotary drive device is a new type of rotary products, which is also called slewing bearing. It is usually compoSEd of worm, slewing bearing, shell, motor and other parts. Because the core component is slewing bearing, it can bear axial force, radial force and overturning moment at the same time. Compared with traditional rotary products, slew drive has the characteristics of simple installation, easy maintenance and saving installation space. The product can be widely used in heavy plate transport vehicles, container cranes, truck mounted cranes, aerial vehicles, solar power generation systems and other engineering machinery and new energy fields. SE Series worm gear drive can realize reverse self-locking.

2.WEA Series slew drive (worm gear)            

WEA Series is a heavy slew drive with high torque and self-locking function. The rotary bearing is used as the driving follower and mechanism attachment. One of the inner and outer rings of the slewing ring is attached with the driving member, driving source and cover, and the other ring is regarded as both the driving follower and the connecting base of the driven working parts. Thus, the slewing bearing itself is full circle rotation With the characteristics of the connecting piece, the driving power source and the main transmission parts are configured efficiently, which makes it a universal deceleration transmission mechanism with simple structure, convenient manufacturing and maintenance, which integrates the functions of rotation, deceleration and driving.

3.Advantages and disadvantages of SE Series slew drive and WEA Series slew drive

According to the difference of variable speed transmission forms of rotary drive, it can be divided into gear type rotary drive and worm gear type slew drive. Inheriting the respective characteristics of gear drive and worm gear drive, theSE two slew drive can adapt to medium high speed and low speed applications respectively. In terms of bearing capacity, the performance of worm gear type is better than that of gear type, and when enveloping worm drive is adopted, its bearing capacity is better than that of gear type The load capacity, anti deformation ability and transmission rigidity are further improved, but the worm gear slew drive is inferior to the gear rotary drive in efficiency.

No matter the gear type or the worm gear type slew drive, Because the size difference between the driving and driven parts is very large, it is easier to realize the transmission with large transmission ratio, which is also difficult for many other types of variable speed transmission mechanism.            

Worm gear transmission has the characteristics of reverse self-locking, which can realize reverse self-locking, that is, only worm can drive worm gear, but not worm gear. This feature makes the slew drive can be widely used in lifting, high-altitude operation and other equipment. It not only improves the technology content of the main engine, but also greatly improves the working stability and safety factor of the main engine. Compared with traditional rotary products, slew drive has the advantages of simple installation, easy maintenance and saving installation space. Compared with the traditional gear transmission, worm gear transmission can get a relatively large reduction ratio. In some cases, it can save the reducer parts for the main engine, so as to reduce the purchase cost for customers and greatly reduce the failure rate of the main engine.

The characteristics of SE Series slew drive and WEA Series slew drive are obvious. The common applications are engineering, construction machinery, solar energy, wind energy and so on. They are also widely used in the field of industrial robots. The above is the summary of the difference between SE Series slew drive and WEA Series slew drive. Xuzhou Wanda Slewing Bearing can provide customized service for you, whether it is the whole WEA Series, SE Series or others.
