Stainless Steel Bevel Gears Straight-Tooth System Ratio 1:1 – 4:1

Stainless steel bevel gears with a straight-tooth system and gear ratios from 1:1 to 4:1 are conical gears designed to transmit power between shafts intersecting at a 90-degree angle. The straight-tooth design features teeth cut directly along the conical surface, parallel to the gear's pitch cone, resembling a spur gear but conical in shape. These gears are typically made from stainless steel grades like 1.4305 (AISI 303) for corrosion resistance, making them suitable for food machinery and harsh environments.

Ratios like 1:1 (miter bevel gears) involve equal tooth counts, while ratios up to 4:1 use differing tooth numbers to adjust torque and speed. They have a 20-degree pressure angle, milled or crowned teeth, and are sold singly, requiring matched pairs for operation. Applications include industrial mixers and printing presses, but they're limited to lower speeds (under 1000 rpm) due to noise and stress from abrupt tooth engagement.
