Caixa de engrenagens da tomada de força (TDF) para roçadeira de martelos T-310A | Substituição com relação de 1:3

Visão geral da caixa de engrenagens da tomada de força (TDF) do cortador de grama de martelos

The T-310A Caixa de engrenagens da tomada de força (TDF) da roçadeira de martelos is a cast-iron right-angle transmission unit that channels tractor PTO power into the high-speed rotation required by flail cutting heads. Built around a 1:3 speed-increasing gear set, this gearbox takes a 540 RPM input and delivers approximately 1,620 RPM at the output shaft — the blade tip speed most flail mowers need for effective vegetation shredding. The housing is manufactured from GGG40 ductile cast iron, a grade chosen specifically for agricultural service because of its impact absorption and fatigue resistance. Peak input capacity is 22.1 kW (roughly 30 HP), and maximum input torque reaches 420 Nm.

Esse caixa de engrenagens da tomada de força do trator serves as a direct dimensional and functional replacement for the Comer Industries T-310A (OEM part reference 310702). The input shaft accepts a standard 1 3/8-inch, 6-spline PTO coupler (Z6), while the output side features a 33 mm h7 precision-ground cylindrical shaft. All bolt patterns and mounting geometry match the original design, allowing installation without frame modifications. The unit ships dry — operators fill with their preferred 80W-90 gear oil (0.8 L capacity) before first use.

Korea Ever-Power PTO Shaft Co., Ltd manufactures this Caixa de engrenagens da tomada de força agrícola under ISO 9001-certified processes with individual bench testing for gear mesh noise, seal integrity, and torque verification. It is well-suited for Korean and Southeast Asian farms where flail mowing of rice paddy levees, hillside brush, and perennial weed growth is a seasonal requirement.

Especificações técnicas

Below is the verified specification sheet for this Substituição da caixa de engrenagens da tomada de força (PTO) unit. All values are based on factory test bench data at standard 540 RPM input. The T-310A supports both increasing (1:3) and reducing (3:1) configurations depending on shaft orientation. For applications at different PTO speeds, contact our technical team for recalculated torque limits.

All gearboxes ship without oil. First oil change after 50-70 operating hours, then every 500-700 hours or at least annually.

Como funciona a caixa de engrenagens desta roçadeira de martelos

Power Transmission Path

The tractor delivers rotational energy through the PTO driveshaft at 540 RPM. This shaft connects to the gearbox input via a 1 3/8-inch, 6-spline coupling, transmitting torque into the first stage of a spiral bevel gear pair. The smaller driving gear meshes with a larger driven gear to multiply speed by three, sending approximately 1,620 RPM to the output shaft that drives the flail cutting head. This 90-degree power redirection is standard geometry for tractor-mounted flail mowers where the PTO input runs horizontally and the blade rotor axis runs perpendicular to the driveline.

Internal Gear and Bearing Assembly

Inside the GGG40 housing, two spiral bevel gears sit on taper roller bearings that manage both radial loads and the axial thrust from the bevel mesh. The gear teeth are case-hardened to handle the impact loads unique to flail mowing — every hammer strike sends a shock pulse back through the drivetrain. Oil bath lubrication coats the gear contact zone and bearings during operation; the 0.8-litre reservoir is compact but adequate for the contact area involved. A breather vent prevents internal pressure buildup as operating temperatures rise. The design allows field-swappable seals on both input and output shafts without full disassembly, reducing maintenance downtime during peak mowing season.

Principais vantagens

Estrutura e Material

Construção de Habitações

The T-310A uses a split-case housing made from GGG40 grade ductile cast iron. This particular alloy contains nodular graphite inclusions that give the metal its distinctive combination of high tensile strength and shock absorption. Unlike grey cast iron, which is brittle and prone to fracture under sudden impact, ductile iron deforms slightly before cracking — a meaningful advantage in flail mower service where blade-to-rock impacts send repeated shock pulses into the gearbox shell. The two housing halves are machined to tight flatness tolerances on the mating surface, then secured with high-strength cap screws and sealed with an anaerobic gasket compound that withstands operating temperatures up to 120 degrees Celsius.

Gear and Seal Details

Inside, a matched pair of spiral bevel gears transfers power through a 90-degree turn. Both gears are forged from chromium-molybdenum alloy steel, then carburized and ground to achieve a surface hardness of 58-62 HRC on the tooth flanks while retaining a tough, ductile core. This "hard skin, soft core" combination prevents surface pitting while allowing the gear body to flex under peak loads without brittle fracture. Taper roller bearings on both shafts are press-fitted into precision-bored housing seats. The input shaft seal is a double-lip nitrile rubber type rated for continuous service from -30 degrees to +110 degrees Celsius. A magnetic drain plug on the bottom of the housing captures ferrous wear particles, giving operators a visual check on internal wear condition at each oil change.

Application Scenarios for Flail Mower PTO Gearboxes

Pasture and Grassland Maintenance

Livestock farms across Korea's central and southern provinces rely on flail mowers equipped with this gearbox to keep pastures trimmed after grazing rotations. The 1:3 ratio delivers the 1,500-1,700 RPM blade speed needed to shred grass stems into fine mulch that decomposes quickly and returns nutrients to the soil. The 22.1 kW input capacity suits the 25-35 HP compact tractors common on mid-size Korean cattle and dairy operations.

Roadside and Embankment Vegetation Control

Municipal crews use tractor-mounted flail mowers to clear weeds, brush, and small saplings along roads, drainage ditches, and reservoir embankments. The GGG40 housing on this caixa de transferência de força is particularly important here, where the cutting head frequently contacts rocks, debris, and uneven terrain. The cast iron absorbs these repeated impacts without developing stress fractures that would sideline an aluminium-housed unit.

Gestão do solo do pomar

Apple orchards in Gyeongsang provinces and pear farms in Chungcheong require periodic flail mowing between tree rows. The high blade speed pulverizes fallen fruit, pruning debris, and cover crop residue without clogging. At 18 kg, this gearbox keeps the overall mower assembly compact enough for narrow inter-row passes on small-to-medium orchard operations.

Gestão da vegetação em parques solares

Solar installations need regular ground cover control to prevent tall vegetation from shading panels. Flail mowers powered by this Caixa de engrenagens da tomada de força cover large flat areas efficiently, and the 500-hour service interval means fewer stops during intensive mowing seasons in late spring and early autumn.
