Ever Power 90 Degree Spiral Bevel Right Angle Speed Reduction Gearbox<\/h1>\n

The EVER POWER 90-degree right-angle speed reduction gearbox combines directional change with speed reduction in a single compact housing. Where a commutator provides direction change only, this unit provides direction change plus speed reduction simultaneously – the efficient choice when a standard-speed motor (750-1450 rpm) must drive a slower-running output device through a 90-degree shaft change.<\/p>\n

Product Overview<\/h2>\n

Speed reduction variants (1.5:1, 2:1, 3:1) are the most widely used bevel gearbox configurations. By combining right-angle drive with speed reduction in one housing, machine designers eliminate a separate inline reducer, reducing total component count, overall drivetrain length, and potential failure points. Typical Uses:<\/strong> Conveyor drive stations | Fan drives | Pump drives | Mixer and agitator drives | Screw press drives | Kiln and rotary drum auxiliary drives. Request a quote<\/a><\/p>\n

How It Works<\/h2>\n

The pinion is on the horizontal input shaft and meshes with a larger spiral bevel crown gear on the output shaft. The ratio between crown gear and pinion tooth counts determines speed reduction: 1.5:1, 2:1, or 3:1. A 1450 rpm motor input produces 967 rpm (1.5:1), 725 rpm (2:1), or 483 rpm (3:1) at the output, while output torque is multiplied by the same ratio (less friction losses). The spiral tooth high face overlap ratio enables a smaller, lighter gearbox for a given torque compared to straight bevel designs.<\/p>\n

Core Advantages<\/h2>\n
\n
📅 One-Stage Direction Change + Reduction<\/strong><\/p>\n

Combines two functions in one housing; eliminates separate inline reducer saving space and cost.<\/p>\n<\/div>\n

📈 Three Ratio Options<\/strong><\/p>\n

1.5:1, 2:1, 3:1 covers the most common motor-to-equipment speed reduction requirements.<\/p>\n<\/div>\n

⚡ Higher Efficiency than Worm<\/strong><\/p>\n

94-96% single-stage; significantly better than comparable worm configurations at these ratios.<\/p>\n<\/div>\n

🛠 Compact Design<\/strong><\/p>\n

Single bevel stage inherently more compact than bevel plus inline combination for same output torque.<\/p>\n<\/div>\n

🔄 Reversible as Speed Increaser<\/strong><\/p>\n

Use the larger-gear shaft as input for generator and test rig speed increase applications.<\/p>\n<\/div>\n<\/div>\n

Structure and Material Details<\/h2>\n

The asymmetric gear pair is precision-engineered with optimized tip relief and lead crowning to reduce edge loading across the full torque range. Housing section sizes are designed for the tooth separation force at maximum ratio. Shafts are stepped to provide both the gear mounting register and interference-fit bearing journal in one component. Oil fill is sized for the maximum fill line consistent with all mounting orientations.<\/p>\n
