Steel Spiral Bevel Gears Spiral Tooth System Ratio 1.2:1 – 1.6:1

Steel spiral bevel gears with a spiral tooth system and ratios between 1.2:1 and 1.6:1 are specialized mechanical components designed to transmit power between intersecting shafts, typically at a 90-degree angle. These gears feature curved, angled teeth (spiral teeth) that provide smoother, quieter operation and higher load capacity compared to straight bevel gears. The gear ratio, ranging from 1.2:1 to 1.6:1, indicates the speed relationship between the pinion and gear, calculated by dividing the number of teeth on the gear by the number of teeth on the pinion. These gears are ideal for applications requiring precise torque transmission, such as in automotive, marine, or industrial machinery.

The gear ratio, ranging from 1.2:1 to 1.6:1, indicates the speed relationship between the pinion and gear, calculated by dividing the number of teeth on the gear by the number of teeth on the pinion.

Typically made from materials like 42CrMo4 (for modules up to 1.5) or 16MnCr5 (for modules 2.0 and above), these gears have induction- or case-hardened teeth for durability, with soft hubs and bores. They are designed with a cyclo-palloid or palloid spiral tooth system, adhering to standards like DIN 3967 for tooth quality. These gears are ideal for applications requiring precise torque transmission, such as in automotive, marine, or industrial machinery.
