Custom Precision Spur Gear
2 month ago
Product details
一、Product Description
This custom precision spur gear with a keyway is manufactured from 42CrMo alloy steel, a material offering excellent strength, toughness, and fatigue resistance. Capable of withstanding high torque and alternating loads, it is ideal for medium-to-high-speed, heavy-duty transmission applications, effectively resisting tooth surface wear and the risk of tooth breakage. The gear undergoes a black oxide surface treatment, creating a uniform protective layer that enhances rust resistance while reducing friction losses on the tooth surfaces. We offer comprehensive OEM customization services, allowing for adjustments to the module, number of teeth, face width, bore diameter, keyway specifications, and set screw locations based on customer drawings. These gears are widely used in power transmission systems such as gear reducers, conveyor equipment, and industrial transmission modules. As a reliable, OEM-quality component, the gear profile, bore, and keyway dimensions are strictly controlled to ensure precise assembly with the drive shaft, stable transmission, and reliable torque output. With its robust mechanical properties, this 42CrMo spur gear is a preferred choice for heavy-duty transmission applications.

三、Manufacturing Process
42CrMo alloy steel bars are cut to size, and Turning Services are used to perform rough turning of the gear blanks’ outer diameter, inner bore, and end faces. For high-precision areas such as the gear’s mounting bore and reference end face, Precision CNC Turning Services are employed for finish turning, with strict control over coaxiality and roundness tolerances. The turned blanks are high precision CNC turned parts. Subsequently, gear hobbing is performed to form straight-tooth profiles, followed by machining of keyways and set screw holes, and deburring. Once all machining is complete, a blackening treatment is applied. Finished parts undergo tooth profile inspection and keyway dimensional verification to ensure assembly accuracy and interchangeability for batch-produced parts.
