EP-B100 ヘビーデューティーコンパクトベーラー用ギアボックス - 70～100kW、ブルーシリーズ増速機
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 ラウンドベーラーギアボックス 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駆動シャフト 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.

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.

現場での応用シナリオ
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
100 KW Without a Tube
Full EP-1800B power capacity in a compact direct-mount housing. No tube, no intermediate bearings, no extension couplings. Simpler installation, fewer maintenance points, and a more rigid baler frame connection.
デュアル出力インターフェース
Both 8×42×48×8 spline and Ø190 bolt flange in one unit. Cover spline-coupled and flange-coupled baler drive systems with a single gearbox SKU — simplifying OEM procurement and dealer inventory across multiple baler models.
Extended Bearing Span
The 639 mm housing with 428 mm lower output section provides generous bearing separation for superior shaft support at sustained 1,173 rpm and 100 KW. Less deflection means longer bearing life and quieter operation.
Blue Series Identification
Instant visual identification as a compact baler speed increaser. Blue distinguishes from red tillage gearboxes and green harvester units — faster service, cleaner inventory, fewer installation errors across mixed-equipment farms.
設置およびメンテナンス
取り付け手順
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.
メンテナンススケジュール
◆ 梱包作業の前に毎回 — Check oil level; inspect input and output splines; verify frame bolt torque.
◆ 最初の100時間後 — 初回オイル交換：オイルを抜き、フラッシング後、新しいSAE 80W-90 GL-5オイルを補充します。
◆ 400時間ごと — Oil change (high-RPM thermal interval for speed increasers).
◆ 800時間ごと — Inspect output bearing play; check spline and keyway for deformation; examine input spline condition.
◆ わらシーズン終了 オイルを補充し、露出したシャフト表面に防錆剤を塗布し、PTOを外した状態で保管してください。

顧客レビューと現場報告
★★★★★
“We manufacture mid-size round balers with close-coupled frames that cannot accommodate tube-output gearboxes. The EP-B100 gives us the same 100 KW power rating as the EP-1800B in a direct-mount package that integrates perfectly into our frame design. We switched our entire product line to the EP-B100 last year — zero assembly issues across 80+ units and no field warranty claims on the gearbox.”

“I run a contract baling service with a 130 HP Daedong tractor and a Korean mid-size baler. The EP-B100 handles sustained full-load baling in heavy corn stover without any temperature or performance issues. Previously I was limited to the EP-B80 which was borderline at 80 KW for my application. The B100 gives me the headroom I need with no overheating during long baling days.”

“Our cooperative upgraded from EP-B80 units to EP-B100 across eight balers used for wheat straw and grass hay. The power increase eliminated the thermal shutdowns we occasionally experienced during peak harvest in hot weather. Only 4 stars because the B100’s different input spline (8×32×38×6) required us to purchase new PTO shafts for all eight machines — an additional cost we had not anticipated.”
