ODM Internal gear type horizontal rotary drive device Manufacturer, Factory

The internal gear type horizontal rotary drive device is an integrated mechanical and electrical module that combines "internal gear rotary support" and "horizontal drive assembly".

Its core features are:

Gear internal: The inner ring of the rotary support is equipped with internal gears.

Horizontal input: The motor and reduction system are installed horizontally.

Output rotation: The final output is rotational motion around a vertical axis. 

Product Description

Core Advantages
Unparalleled Central Space

The central area features a large fixed column or an open passage, permanently accommodating large pipelines (hydraulic, electrical, optical fibers), ladders, or elevator shafts without slip rings or entanglements.

Outstanding Rigidity

Loads act directly on the large rotating housing. With a short and symmetrical force flow path, structural rigidity is significantly higher than central flange output designs.

Clean Sealing & Design

All transmission components are enclosed within the rotating housing, offering a smooth shape that achieves high protection levels (IP69K), perfect for harsh operating environments.

Large-Diameter Rotation

Perfectly engineered for demanding industrial and mechanical applications that require driving a large platform, cabin, or drum to rotate.

Typical Application Scenarios
Large Ship Deck Cranes & Radar Bases The center fixes large columns to support hydraulic stations and cables, while the rotating part controls the entire crane arm or radar dome.
Giant Mining & Pier Machinery Rotating Platforms Perfect for installations like the central column of stacker-reclaimers where the rotating part consists of long booms and bucket wheels.
Satellite Communication Ground Station Antenna Drives Designed to keep all central feeders and cables fixed while smoothly rotating the entire heavy parabolic antenna structure.
Large Amusement Facilities (Observation Cabin Drives) Applies driving rotation to structures like Ferris wheel cabins while keeping the main tower column static in the center.
Special Industrial Furnaces / Rotary Kiln Drives Drives the entire kiln body rotation while ensuring the central feed and exhaust pipes remain stable and properly fixed.
Frequently Asked Questions
What are the primary benefits of the central open space in these slewing drives?
The central open passage or fixed column allows for the permanent routing of large hydraulic lines, electrical wiring, fiber optics, or mechanical structures like ladders and shafts without using complex slip rings, preventing cable wrapping or wear.
How do horizontal slewing drives maintain high structural rigidity?
The external load acts directly on the outer rotating housing. This structural setup creates a short, symmetrical force path, yielding far superior rigidity and load distribution compared to traditional center-flange output setups.
Are these units protected against harsh environmental conditions?
Yes. Because all primary transmission parts are fully enclosed within the rotating housing, these slewing drives achieve up to IP69K protection, making them ideal for heavy marine, mining, and dusty industrial applications.
What range of tracking precision can be expected from the WSP series?
The WSP series offers high tracking precision tailored to application needs, ranging from ≤0.1° for advanced tracking systems (like satellite ground antennas) to ≤0.2° for heavy machinery applications.
Which industries find the WSP series most applicable?
Typical industries include marine (ship deck cranes), satellite communications (antenna base rotation), bulk material handling (stacker-reclaimers), heavy entertainment rides (Ferris wheel cabins), and processing industries (rotary kilns).
