Steel straight bevel gears with a straight tooth system and a 2:1 ratio are conical gears designed to transmit power between intersecting shafts, typically at a 90-degree angle. The 2:1 ratio indicates that the larger gear (driven gear) has twice as many teeth as the smaller gear (pinion), resulting in the driven gear rotating at half the speed of the pinion while doubling the torque. These gears have straight teeth cut parallel to the cone's generators, resembling conical spur gears, which makes them simpler to manufacture but noisier at high speeds due to abrupt tooth engagement. Commonly made from materials like C45 steel, they are used in applications like machinery, automotive differentials, and power tools, with a typical speed limit of 1000 feet/min or 1000 rpm for small gears to avoid excessive noise and stress. They are sold individually, requiring matched pairs for operation, and are not interchangeable with other gear types.
