BLED ชุดเกียร์ทดรอบแบบไซโคลสองขั้นตอนแนวตั้งแบบติดตั้งหน้าแปลน

ภาพรวมผลิตภัณฑ์

เดอะ BLED cyclo gear reducer combines double-stage cycloidal reduction with a vertical flange-mounted housing configuration. This produces an extremely high-ratio, compact-footprint drive unit that mounts directly above or below the driven equipment through a bolt-on flange interface. The BLED double stage vertical cycloidal gearbox reaches compound ratios from 99:1 to 7,569:1, delivering output shaft speeds as low as 0.2 rpm from a standard 1500 rpm motor input.

Frame sizes range from 120 through 184. The smaller frames (120, 130) weigh between 72 and 95 kg and suit medium-duty agitator drives, while the larger frames (174, 184) weigh 700 to 1,280 kg and handle heavy sludge thickeners, rotary dryer feeds, and large-scale industrial turntable positioners. All BLED vertical flange-mounted cyclo drive units feature GCr15 chromium bearing steel cycloidal discs, alloy steel pin rings, and HT200 cast iron housings with precision-bored bearing seats.

The BLED is dimensionally interchangeable with Sumitomo vertical double-stage equivalents. This cross-reference is provided solely for customer selection convenience.

Retrofit and Upgrade Guide: Replacing Other Reducer Types with the BLED

Many facilities upgrading from aging เกียร์ทดรอบแบบหนอน or multi-stage helical gearboxes to the BLED double stage cycloidal gearbox face a common set of installation questions. This guide addresses the most frequent retrofit scenarios.

Replacing a Vertical Worm Reducer

Worm reducers and BLED cycloidal units rarely share the same flange bolt pattern or shaft dimensions. The retrofit typically requires a custom adapter plate that bridges the old bolt hole positions to the BLED flange pattern. Korea Ever-Power supplies pre-machined adapter plates for common worm-to-cyclo conversions. Provide us with the old unit's flange drawing and we will supply a matched adapter with the BLED order. The key benefit of this conversion is the efficiency gain: at equivalent ratios above 100:1, switching from worm to cycloidal often improves transmission efficiency by 20 to 30 percentage points.

Replacing a Vertical Multi-Stage Helical Unit

Helical-to-cycloidal conversions are typically motivated by improved shock load tolerance and reduced maintenance. The BLED vertical flange-mounted cyclo gear reducer is usually shorter in axial length than a 3-stage or 4-stage helical box at the same ratio, which may require spacer blocks or a modified mounting bracket to maintain correct vertical alignment. Shaft diameter differences are handled by coupling adapters or by ordering the BLED with a custom output shaft diameter to match the existing driven connection.

Replacing a Same-Brand Cycloidal Unit

When replacing an existing Sumitomo, Nidec, or other cycloidal brand with the Ever-Power BLED, the conversion is usually a direct bolt-in. The flange bolt circle, shaft dimensions, and center height are matched to the original equipment manufacturer's specifications. Send us the existing nameplate data (brand, model number, ratio, and frame size), and our engineering team will confirm the matching BLED frame within one business day. This is the simplest retrofit path, requiring no adapter plates, no bracket modifications, and no re-alignment of the driven equipment.

Applications in Heavy Industry and Mining

เดอะ BLED cyclo gear reducer sees regular deployment in heavy-duty industrial sectors where reliability under punishing conditions is more important than upfront cost savings. These environments push equipment harder than typical manufacturing applications, and the cycloidal mechanism's multi-tooth rolling contact provides a distinct advantage over single-tooth-pair gear systems in absorbing the shock loads common to these industries.

Foot-Mounted vs Flange-Mounted Cyclo Reducers: When Does Each Configuration Make Sense?

The BLED belongs to the flange-mounted family, while its counterpart the BWED uses foot mounting. Both deliver the same internal reduction performance, but the mounting method determines how the unit connects to your equipment and what structural support is required. Choosing the right configuration at the design stage avoids costly retrofit work later.

เดอะ BLED vertical flange-mounted cyclo gear reducer is the natural choice when the output shaft must point downward into a tank, vessel, or processing chamber. The flange interface self-centers during installation, which simplifies alignment compared to a foot-mounted unit where the base must be shimmed and grouted to achieve correct shaft centerline height. For vertical agitator drives in chemical reactors, wastewater digesters, and food blending tanks, the BLED eliminates an entire alignment step from the installation process.

The foot-mounted BWED remains preferable for horizontal drive trains where the reducer sits on a concrete pad or steel frame at floor level, such as conveyor head drives, kiln rotation mechanisms, and machine tool feed systems. In these layouts, the BWED's four-bolt foot provides a stable, vibration-resistant platform that distributes reaction torque evenly across the foundation.

คำถามที่พบบ่อย

When should I choose the BLED vertical flange-mounted cyclo gear reducer instead of the BWED horizontal foot-mounted version?

Choose the BLED when the output shaft must point downward (or upward) into a vessel, tank, or vertical mechanism. The flange mount eliminates the need for a floor-level baseplate and simplifies vertical shaft alignment. Choose the BWED when the drive train runs horizontally at floor level.

Does the BLED double stage cycloidal gearbox need an oil pump for vertical mounting?

Yes. In vertical orientation, the upper cycloidal stage sits above the oil bath level. An internal oil pump driven by the input shaft circulates lubricant to the upper bearings. This pump is included as standard on all BLED vertical-rated models. Verify that the pump is engaged before first start.

Can the BLED handle the weight of a heavy agitator impeller hanging from the output shaft?

Within limits. The output shaft bearings handle both torque and axial thrust from the impeller weight. For heavy impellers or long shaft assemblies that create significant axial and bending loads, an external thrust bearing support mounted below the BLED is recommended. Provide the impeller weight and shaft length in your inquiry so our team can verify bearing capacity.

Is it possible to retrofit a BLED in place of an old worm reducer without modifying the mounting frame?

In most cases, a custom adapter plate is needed because worm and cycloidal flange bolt patterns differ. We supply pre-machined adapters designed for common worm-to-cyclo conversions. Send us the existing mounting drawing and we will design the appropriate adapter plate at no additional engineering charge.

What efficiency should I expect from the BLED at a 500:1 compound ratio?

At 500:1, a double-stage cycloidal unit typically operates at 75 to 80% overall efficiency. This is lower than single-stage models (85-92%) because the power passes through two disc-and-pin sets. However, it is still significantly better than a worm reducer at the same ratio, which typically drops below 55%.

Cho Hyun-woo, Senior Maintenance Engineer, Gwangyang Steel Mill (January 2025)

"We fitted BLED-163 units on two ladle turret positioners. The vertical flange mount was essential because there is zero floor space available near the casting area. After 8 months of three-shift operation, the units are running within all thermal and vibration specifications. The multi-tooth contact design clearly handles the intermittent shock loads from ladle positioning better than the helical boxes we replaced."
