Скоростна кутия за ВОМ на фуражния смесител | Заменя Comer C3A

Преглед на продукта

Mowers cut. Tillers dig. Mixers grind. The C3A is a feed mixer PTO gearbox built for the slow, relentless torque demands of TMR (total mixed ration) mixing wagons — the machines that blend silage, hay, grain, and supplements into uniform livestock feed. Unlike mower or cutter gearboxes that spin at 800-1,800 RPM, the C3A operates at PTO speed (540 RPM) in 1:1 mode or reduces to approximately 300 RPM in 1.8:1 mode, delivering the crushing torque needed to turn heavy, wet feed materials through vertical auger screws against high resistance. At 92 kW (125 HP) input capacity, this is one of the most powerful gearboxes in our range — and every kilowatt goes into torque, not speed.

The C3A replaces the Comer Industries C3A with matching 1-3/4 inch, 20-spline connections on both input and output. The cast iron housing contains the heavy-duty gear set required for the sustained, high-torque loading profile that feed mixing imposes — typically 2-4 hours of continuous operation per mixing session, twice daily on commercial dairy operations. This селскостопанска скоростна кутия за ВОМ is compatible with Aksa, DAF Agro, Falke Maschinenbau, and other mixer wagon brands using the Comer C3A specification.

Спецификации

Understanding the Dual Ratio

The C3A offers two internal gear configurations. In 1:1 mode, the output matches the 540 RPM PTO input — used for mixer wagons with lighter feed loads or smaller auger designs that need higher rotational speed. In 1.8:1 reducing mode, output drops to approximately 300 RPM while torque increases proportionally — the configuration for large vertical auger mixers processing heavy, wet silage-based TMR rations where the auger screws encounter maximum resistance. The correct ratio depends on the mixer wagon manufacturer's specification. Check the nameplate on your existing Скоростна кутия на ВОМ or consult the mixer wagon manual to confirm which ratio your machine requires.

The ability to choose between two ratios at the point of purchase — rather than being forced to buy a single fixed-ratio unit — simplifies inventory for equipment dealers and cooperatives that service multiple mixer wagon brands. Both configurations share the same housing, mounting dimensions, and shaft specifications, so a dealer stocking just two SKUs (1:1 and 1.8:1) can service the entire C3A-equipped Скоростна кутия на ВОМ replacement market in their region.

Where This Gearbox Works

Dairy Farm TMR Preparation

Korean dairy operations serving 50-500+ head use TMR mixer wagons to produce consistent, nutritionally balanced feed rations. The C3A powers the vertical auger screws that blend corn silage, hay, grain concentrates, and mineral supplements into a homogeneous mix. The Скоростна кутия на ВОМ runs at full 92 kW load during the mixing cycle — typically 15-30 minutes per batch — making thermal management and bearing durability critical design factors.

Beef Cattle Feedlot Operations

Large-scale beef operations use mixer wagons for daily ration preparation and distribution. The 1.8:1 reducing ratio is popular in this segment because beef TMR rations tend to be denser (more grain, less moisture) than dairy rations, requiring higher auger torque to achieve proper mixing.

Operating Environment and Maintenance

Feed mixer Скоростна кутия на ВОМ operation differs fundamentally from field implement gearboxes. The loading is sustained and predictable rather than intermittent — the auger screws turn at constant resistance for 15-30 minutes per mixing cycle, twice or more daily. Total annual operating hours on a commercial dairy may reach 700-1,000 hours, comparable to the most intensive field operations. The 92 kW rating generates significant heat during these sustained cycles, so oil condition monitoring is important. Use SAE 90 as specified — not 80W-90, which is thinner at operating temperature and may not provide adequate film thickness at the high contact pressures inside this Скоростна кутия на ВОМ.

The operating environment is generally less dusty than field work but introduces different contaminants — feed particles, moisture from wet silage, and corrosive compounds from fermented materials. Keep the housing exterior clean and inspect shaft seals regularly for feed material buildup that could work past the dust lips. Change oil at the manufacturer-recommended interval or every 500 hours, whichever comes first.

Качество и сертификати

Korea Ever-Power manufactures the C3A under ISO 9001:2015-certified quality management. Each Скоростна кутия на ВОМ undergoes individual bench testing for gear noise, torque accuracy, and seal integrity before dispatch. The cast iron housing material meets agricultural implement grade standards. We provide a 12-month warranty covering manufacturing defects, with replacement seals and bearings stocked for immediate shipment from our Korea warehouse. Technical support for cross-referencing, compatibility verification, and ratio selection is available during Korean business hours.

Driveshaft and Companion Products

Mixer wagon PTO driveshafts must handle the 125 HP continuous torque that the C3A transmits. The 1-3/4 inch, 20-spline connection on both ends requires the heavy-duty shaft class — smaller shafts will fail under these loads. Korea Ever-Power manufactures matched Комплекти от карданни валове rated for the continuous high-torque service that mixer wagons demand, with slip clutch or friction disc overload protection to safeguard the gearbox if the auger encounters a foreign object (wire, rope, tool) in the feed material.

Our каталог на селскостопански скоростни кутии includes the full Comer C-series mixer gearbox range (C3A, C7A, C17) plus side drives, planetary reducers, and chain case assemblies used in various mixer wagon configurations.
