Ever Power 2-Extended Shaft Spiral Bevel Gearbox Reducer<\/h1>\n

The EVER POWER 2-extended shaft spiral bevel gearbox delivers simultaneous power to two output shafts from a single input, enabling synchronized twin-axis drives without external shaft couplings or separate gearboxes. Both extended shaft ends rotate at the same speed and torque, making this ideal for twin-shaft augers, dual-roller conveyors, and synchronized lifting systems.<\/p>\n

Product Overview<\/h2>\n

In the standard bevel gearbox, the cross shaft exits from one side. The 2-extended shaft variant extends this cross shaft through both sides, creating two simultaneous output points. Single input with dual output is the most common configuration; dual input with single output is also available. Primary Uses:<\/strong> Twin-shaft screw conveyors | Dual-roller conveyors | Agricultural fertilizer spreaders | Synchronized lifting platforms | Twin-drum winding systems<\/p>\n

How It Works<\/h2>\n

The crown gear on the cross shaft is machined as a full-width gear extending across the entire housing bore. Both sides of the cross shaft are supported by tapered roller bearing pairs, and both shaft ends exit the housing through lip-sealed bearing covers. The spiral bevel pinion drives the crown gear, which distributes torque equally to both extended shaft ends rotating at the same direction and speed – making external synchronization hardware unnecessary.<\/p>\n

Core Advantages<\/h2>\n
\n
↔ Twin Simultaneous Output<\/strong><\/p>\n

Both extended shaft ends deliver equal torque simultaneously; no synchronization shaft required.<\/p>\n<\/div>\n

📈 Simplified Drivetrain<\/strong><\/p>\n

Replaces two gearboxes plus coupling – reduces parts count, weight, and failure points.<\/p>\n<\/div>\n

⚙ Equal Load Distribution<\/strong><\/p>\n

Symmetric cross shaft design ensures equal bearing loads on both sides; extends bearing life.<\/p>\n<\/div>\n

🔄 Custom Shaft Lengths<\/strong><\/p>\n

Extended shaft protrusion length customizable to match existing machine center-line distances.<\/p>\n<\/div>\n

🛠 All Four Ratios<\/strong><\/p>\n

1:1, 1.5:1, 2:1, 3:1 available; same ratio applies equally to both output shafts.<\/p>\n<\/div>\n<\/div>\n

Structure and Material Details<\/h2>\n

The housing is elongated along the cross-shaft axis to accommodate both extended shaft bearing housings. Both output shaft exits are sealed with double-lip NBR seals and labyrinth grooves. Crown gear: 20CrMnTi alloy steel, carburized and ground to Grade 5-6. Cross-shaft diameter sized with safety factor 2.0 on yield. Bearing pairs on both output sides are pre-loaded to control backlash.<\/p>\n
