EP-B100 Heavy-Duty Compact Baler Gearbox — 70 to 100 KW, Blue Series Speed Increaser

EP-B100 Heavy-Duty Compact Baler Gearbox — Product Overview

Heavy-Duty Power in a Compact Form Factor

Mid-to-large round balers and commercial straw return machines operating in the 95–135 HP tractor class need more power than the EP-B80 can deliver, but their frame geometry does not accommodate the 900+ mm tube of the EP-1800B. The EP-B100 heavy-duty compact yuvarlak balya makinesi şanzımanı fills this exact gap: 100 KW continuous power in a direct-mount blue housing that bolts to the baler frame without any tube extension, intermediate shaft, or separate bearing supports.

1,173 RPM Output — Calibrated for Heavy Baling

The EP-B100’s 0.46 : 1 ratio produces 1,173 rpm — a speed optimized for mid-to-large baler chamber rollers and pickup reels that are physically larger and heavier than those in compact balers. These larger components achieve their target surface speed at a slightly lower RPM than compact-baler counterparts, and the 1,173 rpm output is precisely calibrated to match this requirement. Running a large baler at the faster 1,234 rpm of a tube-output unit would over-speed the rollers, increasing vibration and accelerating bearing wear without improving bale quality.

8×32×38×6 Spline Input

The EP-B100 uses an 8×32×38×6 spline input — a different profile from the EP-B80. This spline is widely used on mid-power Korean agricultural equipment and connects directly to standard PTO tahrik mili assemblies without adapters. Verify your existing PTO shaft spline matches the 8×32×38×6 specification before ordering, or contact Korea Ever-Power for a compatibility check.

Blue Series Comparison — EP-B80 vs. EP-B100

Korea Ever-Power’s Blue Series compact baler gearboxes are available in two power tiers. Both share the same direct-mount philosophy, blue housing identification, and dual output interface, but differ in power rating, ratio, and internal spline specifications:

Heavy-Duty Compact Engineering — How the EP-B100 Handles 100 KW

Enlarged Gear Set with Greater Tooth Contact

The EP-B100 uses a larger spiral bevel gear pair than the EP-B80, with increased tooth face width and pitch diameter. The additional tooth contact area distributes the 100 KW load across a larger gear mesh surface, keeping the contact stress per unit area within the same safe design limits as the lighter EP-B80 at its 80 KW rating. This scaling approach means the EP-B100 achieves its higher power ceiling without resorting to exotic materials or unconventional tooth profiles — the same proven 20CrMnTi alloy steel at 58–62 HRC does the job, simply with more contact area to share the load.

Reinforced Housing with Extended Output Section

The EP-B100’s 639 mm overall length (versus 460 mm for the EP-B80) reflects a reinforced housing design that provides additional bearing span and wall thickness at the critical output section. The Ø224 mm upper housing section encloses the enlarged gear chamber, while the extended 428 mm lower section houses the output bearings with generous separation for improved shaft support rigidity. This extended bearing span is essential for controlling shaft deflection at the output under 100 KW sustained loads at 1,173 rpm.

Thermal Management at 100 KW

The larger housing volume provides a greater oil capacity and more external surface area for convective heat dissipation — both critical at 100 KW continuous operation. The EP-B100 maintains oil temperatures below 85°C during sustained full-load baling in 35°C ambient conditions, keeping the lubricant within its optimal viscosity range throughout the straw-season workday. The 400-hour oil change interval (standard for all Korea Ever-Power speed increasers) accounts for the thermal load on the oil at these elevated power levels.

Mid-to-Large Round Balers with Close-Coupled Frames

Some mid-to-large round balers (1.2–1.4 meter bale diameter) use close-coupled frame designs where the drive input hub sits within direct reach of a mounted gearbox — no tube extension needed. The EP-B100 serves these machines with the same 100 KW power ceiling as the tube-output EP-1800B, but in a shorter, more rigid direct-mount package. The 1,173 rpm output matches the roller and pickup speeds these larger-chamber balers require for consistent bale density at full-width straw intake.

Commercial Straw Return Machines

High-capacity straw return machines processing heavy rice straw or corn stover at 100+ HP tractor power demand the EP-B100’s full 100 KW rating. The reinforced housing and enlarged gear set handle the sustained torque loads of high-volume chopping without the thermal limitations that affect lighter gearboxes during continuous all-day operation. The direct-mount configuration suits machines with centrally positioned chopping rotors that do not need a long-reach tube output.

Multi-Crop Heavy-Duty Processing

Farms and contract operators baling multiple crop types — rice straw, wheat straw, and corn stover — need a gearbox that handles the heaviest material without compromise. Corn stover demands significantly more compression force than rice straw, and the EP-B100’s 100 KW rating provides the thermal and torque margin to process this thicker, more fibrous material at full ground speed without backing off tractor power to protect the gearbox.

Why Choose the EP-B100

Kurulum ve Bakım

Montaj Prosedürü

❶ Secure the EP-B100 housing to the baler frame mounting points. Align the output spline or flange with the baler’s internal drive coupling. Torque frame bolts in a star pattern.

❷ Connect the output using either the 8×42×48×8 spline (for spline-coupled balers) or the Ø190 bolt flange (for flange-coupled designs). Torque output bolts to specification.

❸ Connect the PTO drive shaft to the 8×32×38×6 input spline. Verify full engagement depth and install the safety guard. Ensure the PTO shaft angle does not exceed the universal joint’s rated limit.

❹ Fill gear oil (SAE 80W-90 GL-5) and run a 5-minute idle test. Verify smooth 1,173 rpm output rotation, zero leaks, and no abnormal noise before field engagement.

Bakım Programı

◆ Before every baling session — Check oil level; inspect input and output splines; verify frame bolt torque.

◆ İlk 100 saatten sonra — İlk yağ değişimi: yağı boşaltın, temizleyin ve yeni SAE 80W-90 GL-5 yağı ile doldurun.

◆ Her 400 saatte bir — Oil change (high-RPM thermal interval for speed increasers).

◆ Her 800 saatte bir — Inspect output bearing play; check spline and keyway for deformation; examine input spline condition.

◆ End of straw season — Top off oil; apply corrosion inhibitor to exposed shaft surfaces; store with PTO disconnected.

Yardımcı Ürünler ve Tahrik Sistemi Bileşenleri

PTO Tahrik Milleri

Korea Ever-Power supplies matched cardan shafts with the 8×32×38×6 spline interface for direct connection to the EP-B100’s input. Properly rated shaft selection is critical at 100 KW — the shaft must handle full tractor PTO torque without speed reduction at the input side.

Off-Season Tillage Gearboxes

Tractors running the EP-B100 for autumn straw processing typically mount a döner kültivatör dişli kutusu for spring and summer tillage work. Korea Ever-Power manufactures the complete range of intermediate gearboxes from 40 to 150 KW, keeping your tractor productive across every season.
