Designing & Manufacturing ANSI Standard Steel Spur & Bevel Gears for Power Transmission
Donghua specializes in the design and manufacturing of ANSI standard steel gears-precision components that transmit power, change direction, and modify torque in industrial machinery. Our portfolio includes both spur gears for parallel shaft applications and bevel gears for intersecting shaft drives. As a leading global manufacturer since 1991, we combine advanced heat treatment, precision machining, and decades of power transmission expertise to deliver gears that perform reliably in the most demanding environments.
Our Gear Technology: Precision Engineering for Reliable Power Transmission
ANSI standard steel gears are the backbone of industrial power transmission. Donghua manufactures both spur and bevel gears to exacting specifications:
Spur Gears: The simplest and most common gear type, with straight teeth parallel to the axis of rotation. Ideal for transmitting power between parallel shafts with high efficiency.
Bevel Gears: Conical-shaped gears designed for intersecting shafts (typically 90 degrees). They change the axis of rotation and can modify torque-either increasing or decreasing it-while inversely affecting angular speed.
Key Capabilities: Module range 0.5–16, teeth count 11–180, hardened teeth (35-55 HRC), materials including 20CrMnTi, 20Cr, 40Cr, and C45.

Bevel gears allow you to modify torque and speed through gear ratio selection. The mechanical advantage (MA) is determined by the relationship between torques, radii, and tooth counts:
Mechanical Advantage: MA = τb/τa = rb/ra = Nb/Na (where N is the number of teeth)
Torque Modification: Increasing the number of teeth on the driven gear results in larger output torque.
Speed Relationship: Higher mechanical advantage reduces output speed: MA = ωa/ωb
Typical Ratios: A 10:1 gear ratio for increased torque, or 1:5 for increased speed.
