Gearbox Baler Kompak EP-B80 — 50 hingga 80 KW, Peningkat Kecepatan Pemasangan Langsung Input Samping

EP-B80 Compact Baler Gearbox — Product Overview

Compact Direct-Mount — No Tube Required

Not every baler needs a long-tube gearbox. Compact round balers, light-duty straw return machines, and smaller straw choppers position their internal drive hub close to the PTO attachment point — within the reach of a directly mounted gearbox housing. The EP-B80 compact gearbox mesin pengepak jerami bundar is engineered for exactly this configuration: a short, rigid unit that bolts directly to the baler’s structural frame with no intermediate tube, no extension shaft, and no separate bearing supports.

Side-Input Power Path

Unlike the top-mounted input on the EP-1800B/EP-2250B family, the EP-B80 accepts PTO power through a side-mounted input shaft. This lateral input orientation aligns naturally with baler frame geometries where the Poros penggerak PTO approaches from the side rather than from above. The side-input configuration also lowers the overall height of the gearbox-plus-baler assembly, reducing the machine’s center of gravity for improved stability during hillside baling operations.

1,153 RPM — Tuned for Light-to-Mid Balers

The EP-B80’s 0.468 : 1 ratio produces 1,153 rpm output — approximately 7% slower than the EP-1800B’s 1,234 rpm. This slightly lower speed is deliberately calibrated for compact balers with smaller pickup reels and chamber rollers that achieve optimal material handling at moderate rotor speeds. The 50–80 KW power rating covers tractors from 68 to 110 HP, matching the compact baler segment where the EP-1800B’s 100 KW ceiling is unnecessary.

Compact Direct-Mount Architecture — Engineering for Close-Coupled Balers

Why Compact Beats Tube for Short-Frame Machines

The EP-1800B and EP-2250B use 900–1,125 mm tubes to bridge the distance between the PTO input and a remotely positioned drive hub. But in compact balers and light straw return machines, the drive hub sits within 460 mm of the PTO connection — a tube gearbox would be oversized, unnecessarily heavy, and waste mounting space. The EP-B80 addresses this by packaging the same speed-increase function into a rigid, direct-mount housing that bolts to the baler frame without any tube extension.

Antarmuka Keluaran Ganda

The EP-B80 provides two output connection options from a single unit: an 8×42×48×8 spline for direct spline coupling, and a Ø190 bolt flange (4-Ø13) for flanged connections. This dual-interface design allows baler manufacturers to use one gearbox model across product lines that have different internal drive hub types — simplifying procurement and spare parts inventory. The stepped output shaft (Ø45 to Ø30/Ø26) accommodates bearing seats and coupling elements at different positions along the shaft length.

Blue Housing Identification

Korea Ever-Power uses a color-coding system across its baler gearbox range: the EP-B80 and EP-B100 compact models feature blue-painted housings, distinguishing them visually from the red-painted tillage gearboxes and the unpainted tube-output baler units. This color coding helps dealers, technicians, and end users immediately identify the gearbox type during installation, maintenance, and inventory management without needing to read nameplate data.

EP-B80 vs. EP-1800B — Compact or Tube-Output?

Choosing between the compact EP-B80 and the tube-output EP-1800B depends on your baler’s frame geometry and power requirements:

Skenario Aplikasi Lapangan

Compact Round Balers (0.9–1.2 m Bale Diameter)

Korean and Japanese compact round balers producing 0.9–1.2 meter diameter bales use shorter frame designs where the drive hub sits immediately behind the PTO connection point. The EP-B80’s 460 mm depth and side-input configuration mount cleanly in these tight envelopes, providing the 1,153 rpm output that smaller chamber rollers and pickup reels require for efficient straw handling at moderate ground speeds.

Light Straw Return Machines

Straw return machines designed for small-to-mid farms (50–80 HP tractors) use compact frame layouts with the chopping rotor positioned close to the PTO input. The EP-B80’s direct-mount design eliminates the heavy tube assemblies that would be overkill for these lighter machines, reducing overall implement weight and keeping the total cost within reach of small farm operators.

Multi-Brand OEM Platform

The EP-B80’s dual output interface (spline plus flange) makes it a versatile platform for OEM baler manufacturers who produce multiple models with different internal drive coupling types. One gearbox SKU covers both spline-coupled and flange-coupled designs, simplifying production procurement and reducing the number of distinct part numbers carried in the assembly warehouse.

Why Choose the EP-B80

Instalasi & Pemeliharaan

Prosedur Pemasangan

❶ Position the EP-B80 on the baler frame with the side-input boss aligned to the PTO drive shaft approach angle. Secure the housing using the frame mounting bolts; torque in a star pattern.

❷ Connect the output to the baler’s internal drive hub using either the 8×42×48×8 spline or the Ø190 bolt flange, depending on your baler’s coupling type.

❸ Connect the PTO drive shaft to the side-mounted input. Ensure the shaft angle does not exceed the universal joint’s rated operating angle. Install the safety guard.

❹ Fill gear oil (SAE 80W-90 GL-5) and run a 5-minute idle test. Verify smooth 1,153 rpm output rotation, zero leaks, and no abnormal noise before field engagement.

Jadwal Pemeliharaan

◆ Sebelum setiap sesi pengemasan jerami — Check oil level; inspect output spline/flange and input shaft seal.

◆ Setelah 100 jam pertama — Penggantian oli pertama: kuras, bilas, isi ulang.

◆ Setiap 400 jam — Penggantian oli (interval termal RPM tinggi).

◆ Setiap 800 jam — Inspect output bearing play; check spline and keyway for wear.

◆ Akhir musim jerami — Tambahkan oli hingga penuh; oleskan penghambat korosi pada permukaan poros yang terbuka; simpan dengan PTO dilepas.

Produk Pelengkap & Komponen Penggerak

Poros Penggerak PTO

The EP-B80’s side-input configuration requires a PTO drive shaft with the correct angular approach. Korea Ever-Power supplies matched cardan shafts with wide-angle CV joints rated for the lateral entry geometry typical of compact baler installations.

Kotak Gigi Pengolahan Tanah di Luar Musim

Tractors running the EP-B80 for autumn straw baling typically mount a gearbox kultivator putar for spring and summer tillage. Korea Ever-Power manufactures the complete range of tillage intermediate gearboxes from 40 to 150 KW, keeping your tractor productive year-round across all seasons.
