EP03型干草翻晒机用农业齿轮箱

EP03 翻晒机齿轮箱 — 专用 2.63:1 转子驱动

EP03 是一款专用 动力输出轴变速箱 专为翻晒机转子驱动应用而设计。许多农用变速箱服务于多种农机具，而EP03则专注于一项任务：通过精确的2.63:1减速比，将400转/分的水平动力输出轴输入转换为约152转/分的垂直转子输出。这种专注的设计造就了一款针对翻晒机特定负载模式、转速范围和安装要求而优化的变速箱。

Hay tedding is fundamentally different from other PTO-driven operations. The tedder's rotor arms contact the cut hay windrow in a cyclic pattern — each tine arm experiences a brief peak load as it lifts and throws the hay, followed by an unloaded return arc through open air. This creates a pulsating load signature that differs from the steady-state loading of a rotary cutter or the continuous heavy loading of a feed mixer. The EP03's gear geometry, bearing selection, and lubricant volume are calibrated for this specific cyclic pattern rather than for the worst-case continuous load that general-purpose gearboxes must accommodate.

对于韩国的牧草养殖场——忠清道和全罗道的奶牛场、江原道的肉牛场以及首尔附近日益增多的马场——EP03 农业齿轮箱 提供了一种尺寸合适的解决方案，既避免了尺寸过大的通用齿轮箱的成本，也避免了尺寸过小的替代方案（并非为耙草机服务而设计）的过早失效风险。

 

技术规格

The 400 RPM input speed is a non-standard PTO speed — most agricultural PTO systems deliver 540 or 1000 RPM. The 400 RPM specification indicates that the EP03 is designed for implements with a dedicated speed reduction stage between the tractor PTO and the gearbox input, or for tractors with adjustable PTO speed settings. Korean operators should verify their tractor's PTO output speed matches the 400 RPM specification before installation, or confirm that an intermediate speed reduction device is present in the drive line.

何时选择 EP03 — 选择决策指南

Selecting the right gearbox for a hay tedder involves matching the gearbox to the implement's specific operational requirements. The EP03 fits a defined envelope of conditions. Operating outside this envelope suggests a different gearbox model.

EP03 是最佳选择

• ● 您的搂草机使用 400 RPM 的输入转速（可以通过减速动力输出轴或传动系统中的中间减速装置实现）。
• ● 为了有效撒播干草而不损失作物叶片，转子转速大约需要达到 150 转/分钟。
• ● 您的耙草机机架采用十字型 (X) 输入轴接口连接变速箱。
• ● 您正在更换旋转式耙草机上现有的 EP03 或尺寸相同的齿轮箱。
• ● 您的应用场景是轻型至中型干草翻晒，采用循环式（非连续式）装载。

考虑采用不同的模型

• ⚠ Your PTO delivers 540 or 1000 RPM without an intermediate reduction — the EP03's 400 RPM input specification will not match, and running at higher input speed risks bearing and gear damage
• ⚠ 您的搂草机每个变速箱有超过 6 个转子臂，或者在厚重的草条上作业，产生连续（而非循环）载荷——这就需要一个扭矩容量更高的重型变速箱。
• ⚠ 您的农机具需要不同的传动比——有些搂草机在干燥条件下需要更快的转子转速（更低的传动比），而有些搂草机则需要更慢的转速（更高的传动比）来处理苜蓿等娇嫩作物。
• ⚠ 您的变速箱安装接口采用的是花键式输入轴，而不是十字（X）式输入轴——轴接口不匹配需要适配器或更换变速箱型号。

专用翻晒机齿轮箱与通用角传动装置

有些操作人员试图在搂草机上使用速比相近的标准直角变速箱。虽然这种变速箱在尺寸上可能匹配，但性能和使用寿命方面的差异却非常显著。

The core advantage of the EP03 over a general-purpose alternative is precision matching. Hay tedding requires a specific rotor speed window — too fast and the tines shatter dry leaf material (reducing forage nutritional value), too slow and the hay is not adequately spread for even drying. The EP03's 2.63:1 ratio at 400 RPM input produces the specific rotor speed that optimizes spreading action. A general-purpose gearbox with a 2.5:1 or 3:1 ratio produces a rotor speed 5-15% outside the optimal window, which accumulates into measurable forage quality differences over a season of tedding operations.

韩国干草和饲料作业应用

• ◈ 奶牛饲料作业 忠清南道和全罗南道的韩国奶牛场自行生产干草和青贮饲料，并使用翻晒机加速收割后的田间干燥。EP03 驱动翻晒机的转子以精确的速度运转，将收割的牧草均匀地铺撒在田间，同时最大限度地减少叶片损失。对于优质奶牛饲料而言，保留叶片至关重要——叶片含有奶牛产奶所需的大部分蛋白质和可消化能量。
• ◈ 肉牛干草生产 — Korean Hanwoo cattle operations, particularly in Gangwon-do and Gyeongsangbuk-do mountain regions, produce timothy hay and Italian ryegrass for winter feed. These operations run tedders during the May-October growing season, accumulating 200-400 gearbox operating hours annually. The EP03's optimized design for cyclic loading provides reliable season-long service at these duty levels without the maintenance intensity that a mismatched gearbox would require.
• ◈ 马术设施干草管理 — Horse farms and equestrian training centers near Seoul, Jeju Island, and other Korean metro areas require premium-grade hay with high leaf retention and minimal dust. The EP03's precise rotor speed control through the 2.63:1 ratio helps maintain 动力输出轴变速箱 支持优质干草质量的性能标准——这是马匹养殖场的首要任务，因为饲料质量直接影响动物的健康和生产性能。
• ◈ 农业服务提供商 — Korean custom hay operators who provide tedding and baling services to multiple farms carry spare gearboxes to minimize field downtime. The EP03's specific application focus means service operators stock one gearbox model for their tedder fleet rather than tracking multiple general-purpose alternatives with different ratios and mounting configurations.

转子转速和泰丁效率分析

变速箱传动比、转子转速和翻晒质量之间的关系并非线性关系。转子转速的微小变化就会对牧草处理产生可测量的影响。

2.63:1 的转速比处于有效翻晒范围的中间位置。在 152 转/分的转子输出转速下，耙齿尖端的转速既足以将干草提起并抛撒到广阔的范围内，又不会过快导致冲击力过大而压碎干燥的叶片。韩国的牧草条件——干草通常需要翻晒两次（一次是在收割后仍略微潮湿时，一次是在田间部分干燥后）——得益于这种平衡的转速，因为相同的转子转速在两种不同的水分含量下都能有效工作。

包装、运输和收货检验

• ● 包装标准 每台EP03均采用独立的保护纸箱包装，内部泡沫填充物可有效防止运输过程中外壳受到冲击。输入轴和输出轴均配有保护盖，以防止花键或螺纹损坏。纸箱内装有干燥剂，可在储存和运输过程中控制湿度，防止加工表面氧化。
• ● 油位状态 — EP03 出厂时不含润滑油。首次使用前，请加注 SAE 80W-90 GL-5 齿轮油至油位塞处。切勿在无油状态下运行变速箱，即使是短暂运行也不行——锥齿轮在无润滑的情况下接触会导致表面立即出现无法修复的划痕。
• ● 收货检验 — 收货后，请在打开包装前检查纸箱是否有运输损坏。拆箱后，用手旋转输入轴数圈，以确认齿轮啮合顺畅。检查壳体是否有裂纹（尤其是在安装螺栓凸台周围），并确认两个轴封均完好无损且安装到位。如有任何损坏，请在收到后 48 小时内报告。
• ● 安装前的储存 — 将EP03存放在干燥、有遮盖的地方，避免阳光直射。内部加工表面的防腐涂层可提供6-12个月的储存保护。如果需要更长时间的储存，即使近期不打算安装，也应向变速箱内加注润滑油——与原厂防腐剂相比，润滑油能提供更优异的长期防腐蚀保护。

完成泰德驱动线

EP03 通过以下方式连接到拖拉机动力输出轴 (PTO)： 动力输出轴 sized for the tedder's power requirements. For tedder applications, a PTO shaft with a slip clutch provides overload protection when tine arms encounter obstacles (rocks, fence posts, irrigation risers) that produce sudden peak loads exceeding the gearbox's design torque. Shear bolt protection is also acceptable but requires carrying spare bolts in the field for immediate replacement after a protection event.

常见问题解答

我可以在不使用减速器的情况下，将 EP03 安装在 540 RPM 的动力输出轴上吗？
不。EP03 型号的额定输入转速为 400 转/分。如果以 540 转/分的转速运行，输出转子转速将增加到约 205 转/分——远高于最佳翻晒转速范围——并且轴承和齿轮的负载也会超出设计规格。如果您的拖拉机动力输出轴 (PTO) 的转速只有 540 转/分，您可以选择在 PTO 和变速箱之间安装一个串联减速装置，或者选择一款专为 540 转/分输入转速设计的、具有更高减速比的翻晒机变速箱，以产生约 150 转/分的输出转速。

一台EP03变速箱可以驱动多少个转子位置？
EP03 驱动单个转子位置。多转子搂草机（4、6 或 8 个转子）每个转子使用一个变速箱，通过横轴驱动系统连接，该系统同时将动力输出轴 (PTO) 的动力分配给每个变速箱。所需的 EP03 单元数量与搂草机机架上的转子位置数量相匹配。

在韩国的干草生产中，其预期使用寿命是多久？
对于典型的韩国牧草作业，每年运行200-400小时，EP03在标准维护（每年更换机油、季前密封件检查）下可提供8-12个作业季的服务。年运行时间更长或翻晒厚重潮湿的草条的作业可能需要缩短轴承维护周期。磨损的第一个迹象通常是齿轮噪音增大——应在噪音增大导致轴承失效之前及时处理。

EP03 是否适用于除牧草以外的其他作物翻晒？
The EP03's 2.63:1 ratio and ~152 RPM output speed work well for most tedded crops including timothy, orchardgrass, Italian ryegrass, and mixed grass-legume hay. For pure alfalfa or clover tedding, some operators prefer slightly lower rotor speed (higher ratio) to minimize leaf loss from these more fragile legume crops. Consult our technical team if your primary crop is pure legume hay.

EP03 在淡季存放期间需要进行哪些维护？
存放前加满油，以尽量减少壳体内的空气空间（空气中含有水分，会促进腐蚀）。清除壳体外部的干草碎屑和泥土，以免水分滞留。用塑料盖或胶带盖住输入轴和输出轴的开口，防止昆虫和水分进入。存放在干燥、有遮盖的地方。

韩国牧草经营者报告

张敏硕，奶牛场——忠清南道洪城，2025年9月

"Replaced the original tedder gearboxes on our 6-rotor unit after 9 seasons. The EP03 replacement gearboxes produced noticeably smoother rotation than the worn originals — less vibration in the tedder frame, and the hay spread pattern is more even. Our nutritionist measured 1.5% higher protein in the first cutting after the gearbox swap, likely because the correct rotor speed stopped shattering leaf material."

崔妍瑞，韩牛养殖场——江原道平昌，2025年7月

"At elevation in Gangwon-do we only get 3 cuttings per year, so every cutting has to be tedded efficiently to dry before the next rain. The EP03 gearbox on our 4-rotor tedder has handled 3 seasons of mountain hay operation — uneven terrain, rocky fields, occasional tine impacts on stones. No bearing noise yet. The compact size helps on our narrow mountain field access lanes."

Shin Dong-woo，定制干草操作员 — 忠清南道瑞山市，2025 年 6 月

"We ted for 40+ farms across the Seosan area. Our main tedder runs 600+ hours per season — harder use than most farm-owned units. EP03 gearboxes last us 4-5 seasons at this duty level before needing bearing service. I carry one spare gearbox on the service truck during peak season. The 20-minute swap time means we lose less than half an hour if one fails in the field."

李娜妍，马场——济州岛，2025年5月

"Horse hay quality standards are strict — dusty or stemmy hay causes respiratory problems in performance horses. The EP03's rotor speed produces a gentle spreading action that preserves leaf quality. We tested hay from our EP03-equipped tedder against hay from a farm using a faster generic gearbox. Our hay had visibly more intact leaf material and tested 2% higher in digestible protein."

韩承佑，农机经销商——全罗南道罗州市，2025年4月

"EP03 is our most-requested tedder gearbox. Most calls come from dairy and beef operations replacing worn units on imported tedders. The cross-type input shaft fits the majority of European-style tedders that Korean farms operate. We stock 8-10 units year-round and typically sell through the inventory twice during the main hay season from May to September."
