Product Overview<\/h2>\n

This unit is built around a precision-ground spiral bevel gear pair. The helical tooth profile distributes load across multiple teeth simultaneously, producing smoother torque transfer and substantially lower noise than straight bevel designs. Available with dual input shafts and multiple output shaft configurations, the unit installs in any orientation. Industries:<\/strong> Agriculture | Food Processing | Building Construction | Forest & Paper | Metalworking | Chemical & Environmental.<\/p>\n

How It Works<\/h2>\n

The input shaft drives a spiral bevel pinion whose helical teeth mesh with the crown gear mounted on the perpendicular output shaft. At 1:1, the output shaft rotates at the same speed as the input. The spiral tooth geometry ensures gradual engagement, eliminating impact loads. Gears are carburized and quenched to HRC 58-62 surface hardness over an HRC 33-40 tough core, providing both wear resistance and shock absorption.<\/p>\n

Core Advantages<\/h2>\n
\n
⚙ Exact 1:1 Ratio<\/strong><\/p>\n

Precise matching of input and output speeds; no unintended speed change at the output shaft.<\/p>\n<\/div>\n

🔊 Low Noise 60-68 dB<\/strong><\/p>\n

Achieved through spiral tooth geometry and precision grinding to ISO Grade 5-6.<\/p>\n<\/div>\n

🔄 Flexible Mounting<\/strong><\/p>\n

Any installation orientation. Dual input and multiple output shaft options available.<\/p>\n<\/div>\n

🔧 Premium Materials<\/strong><\/p>\n

20CrMnTi gears, 42CrMo shafts, cast iron\/ductile iron housing for industrial durability.<\/p>\n<\/div>\n

✅ 94-96% Efficiency<\/strong><\/p>\n

Minimizes energy loss; reduces motor power requirements and operating cost.<\/p>\n<\/div>\n<\/div>\n

Structure and Material Details<\/h2>\n

The housing is precision-machined from cast iron or ductile iron (HBS 190-240). Gears are from 20CrMnTi alloy steel, carburized to 1.0-1.4 mm case depth, quenched and precision ground to Grade 5-6. Shafts from 42CrMo alloy steel (HRC 25-30). Sealing: NBR double-lip seals rated -30 to +120 deg C. Lubrication: GB L-CKC220-460 or Shell Omala 220-460 oil bath.<\/p>\n
