玉米收割机动力输出轴变速箱

Gear sets are manufactured from vacuum-degassed 8620H alloy steel, then carburised and precision-ground to AGMA Class 11 quality — exceeding the AGMA Class 8-9 found in most agricultural gearboxes.

Every housing design is validated through FEA stress analysis and modal analysis to eliminate resonance and stress concentration points — a level of engineering rigour absent from mass-produced budget alternatives.

Our gearboxes are compatible with advanced synthetic lubricants from day one, enabling extended drain intervals of up to 2,000 hours. Many competitors use seal materials that degrade when exposed to synthetic oils.

Proprietary gear tooth profile modifications absorb up to 300% momentary overloads without damage — critical for applications involving sudden impacts from rocks, stumps, or dense crop material.

Optimised gear geometry and bearing preload settings ensure smooth operation from -25°C to +55°C ambient temperature, outperforming competitors that become stiff and noisy in cold conditions.

All shaft seals can be replaced without removing the gearbox from the implement, saving hours of labour compared to designs that require complete gearbox removal for seal replacement.

Before installation, confirm the PTO gearbox specifications against the corn picker’s technical manual. Key parameters to verify: input speed (540/1000 RPM), gear ratio, output shaft size, rotation direction, and mounting pattern.

Disconnect the tractor PTO shaft and secure it in the parked position. Switch off the tractor engine and remove the key. Engage the parking brake and chock the wheels.

Remove the existing gearbox if applicable. Tag and photograph all connections for reference during reassembly. Drain and properly dispose of old lubricant.

Trial-fit the new PTO gearbox to the corn picker frame. Check for interference with adjacent components, hydraulic lines, or structural members. Shim if necessary to achieve correct alignment.

Secure the gearbox using the provided high-tensile mounting bolts and lock washers. Apply thread-locking compound (medium strength, e.g., Loctite 243) to all critical fasteners.

Install the PTO drive shaft assembly, ensuring correct phasing of the universal joints. Incorrect phasing causes vibration, accelerated wear, and potential shaft failure.

Connect the output drive to the corn picker’s mechanism. Use new O-rings, gaskets, or seals at all connection points. Apply sealant only where specified in the installation manual.

Fill the gearbox with fresh lubricant through the filler port. Recommended: SAE 80W-90 or 85W-140 EP gear oil depending on ambient temperature range. Refer to the capacity plate on the gearbox housing.

Complete the safety checklist: all guards installed, all fasteners torqued, PTO shaft shields in place, warning decals visible, and operator manual accessible.

Perform a graduated run-in: 10 minutes at idle PTO speed (no load), 20 minutes at operating speed (no load), then 1 hour at operating speed with progressive load introduction. Monitor for any abnormalities.

The correct gear ratio depends on your tractor’s PTO speed (540 or 1000 RPM) and the required implement speed. For most corn picker applications, ratios between 1:1.29 and 1:3.0 are common. Our engineering team can calculate the optimal ratio based on your specific tractor and corn picker model. 联系我们 请提供您的具体要求，我们将免费为您提供建议。

Yes, our PTO gearboxes are designed as direct replacements for major brand corn picker gearboxes. We offer matching mounting patterns, spline configurations, and gear ratios for popular models from brands like John Deere, Case IH, New Holland, and others. Provide us with your current gearbox part number or machine model for exact cross-reference compatibility.

标准型变速箱可在 5-7 个工作日内从我们的仓库发货。定制型变速箱，例如采用非标准传动比、轴配置或特殊材料的变速箱，通常需要 15-25 个工作日。我们备有大量常用农用变速箱型号的库存，可快速响应紧急订单。

我们建议在运行 50 小时（磨合期）后进行首次换油，以清除齿轮初始磨合过程中产生的金属颗粒。之后，应每 500 小时或每年换油一次，以先到者为准。在严苛工况（高温、多尘环境、连续运行）下，换油间隔应缩短至 250 小时。务必使用指定等级的齿轮油。

是的，我们为批量订单提供阶梯式定价。标准型号的最低起订量仅为 1 台，但批量折扣从 5 台起（5-8% 型号优惠），20 台起（10-15% 型号优惠），50 台以上起（项目价格可协商）。OEM 客户和分销商可享受额外的项目优惠。 索取报价 根据您的具体需求量。

Absolutely. Our corn picker PTO gearbox is designed with generous safety factors (typically 2.0-2.5x rated load) to absorb the shock loads and transient peaks common in corn picker applications. The hardened gear teeth, oversized bearings, and robust housing all contribute to excellent shock load resilience. For extreme applications, we offer reinforced models with even higher ratings.
