EGE7 Series Slewing Drive

The slewing drive gadget is also identified as a slewing reducer, a gear reducer, a turntable reducer, a slewing mechanism, and a slewing drive pair. All reducers use slewing bearings because the direct assistance, plus the auxiliary drive source, utilize gears or worms as the driving components to achieve deceleration and full-circle rotation functions. The composition of the slewing drive primarily involves gears (or worms), slewing bearings, motors, housings, and bases. The slewing drive can be divided into single worm drive, slewing drive, double worm drive, slewing drive, and the particular type of slewing drive.

The slewing drive can be divided into single worm drive, slewing drive, double worm drive, slewing drive, and the particular type of slewing drive.

Slewing drives usually consist of an inner ring separated by balls and an outer ring with helical gears or suitable worm gears. It is mounted on a standard housing containing the worm shaft and shaft support bearings.

Grease fittings allow relubrication of bearing races, worm gears, and support worm shaft bearings. Rings can contain threaded or clearance holes for bolts. The shims usually separate the rolling elements, and the raceways are hardened and ground. Nitrile rubber seals retain lubricant in the bearing and prevent contamination from entering.

Industry Applications

The slewing drive may be utilized in any condition requiring full-circle rotation and variable pace. When it can be necessary to achieve additional fantastic torque energy transmission, more excellent precision motion transmission, or even the variety of a mechanism that calls for a higher degree of compactness and integration from the body structure, the slewing drive may be the most excellent solution.

The more general applications will be the full-circle slewing structure of engineering and development machinery, solar vitality, wind vitality, and long-term automated monitoring machinery. Due to the compact style and short transmission chain, the slewing drive is much easier to realize higher accuracy and even more. It's easy to carry out a digital handle, so there are numerous applications in the discipline of industrial robots.

What Problems Should Be Considered in the Selection of Slew Drive?

A slewing drive is essentially a slewing support device, but it has more advantages than a slewing bearing; increasingly, traditional industries are now using slewing drives to replace slewing bearings.

The slewing accuracy and other conditions that slewing drives can provide enable some mechanical techniques that require precise control. Choosing the right swing drive is critical to the smooth running of machinery.

Many issues should be considered when designing a rotary drive, such as axial load, radial load, tilting moment, positioning accuracy, transmission ratio, etc. So what should be considered when choosing the right slewing drive?

(1) Equipment performance requirements:

We always talk about value for money when we buy something. The same goes for slewing drives. When meeting equipment performance requirements, choosing a smaller slewing drive can save costs. For example, equipment must reach specific loads, achieve greater precision, and withstand more excellent tilting moments. According to different requirements, choose the slewing drive that meets the requirements.

(2) Installation form:

Slew drive has various shapes, which can be installed horizontally and vertically. Therefore, the style of slew drive should be selected according to the installation space conditions of the mechanical equipment.

(3) Operating conditions:

Consider the environmental conditions of the machinery used. The rotary drive has an open and closed type of meeting different working conditions. The enclosed slewing drive is protected by housing and has a higher degree of protection. It can be used in harsh environments such as dust, humidity, sand, etc. Open slewing drives offer better prices and can be used in typical environments.

(4) Rotation direction required by mechanical equipment:

The primary function of slewing drive is rotation. If there is only one azimuth rotation, you can select a single-axis slew drive, then choose horizontal or vertical installation to meet a single azimuth rotation. Still, if the mechanical equipment needs to rotate in different directions, you can select a dual-axis slew drive to complete the horizontal and vertical process.

(5) Rotation accuracy required by mechanical equipment:

The slewing drive provided by HZPT has ordinary and precision products. If the mechanical equipment has high requirements for rotation accuracy, you can choose the precision slew drive. If the mechanical equipment has no requirements on rotation accuracy, you can choose the ordinary accuracy slew drive.

(6) Power source of mechanical equipment:

When choosing a suitable swing drive, it is also necessary to consider whether the power source has sufficient power. If you select a device with a smaller motor and a larger slewing drive, likely, the engine will not drive the slewing drive, resulting in the slewing drive being unable to rotate. Therefore, when choosing a slewing drive, the power source of the mechanical equipment must also be considered.

Slewing drive selection is a matter of considering these issues, which can be a complicated process for you. You don't need to solve these problems yourself. Contact us, and our engineers will help you choose the right economic slewing drive.
